Dear reader, Time flies when you’re having fun, and that means that we are already halfway through this lustrum year! About time for a new T-Licht as well, since there have been many great activities to celebrate the 60th birthday of Japie during the diesweek. And of course there are some nice celebrations coming up during the second half of the year that will already be considered in this T-Licht. My name is Limi Kalapurackal and I am a first year bachelors student. One of those who is doing the bachelor’s program in English for the first time! I was born and raised mainly in Vienna, Austria but I am originally from the southern state of Kerala in India (lived there for six years). I have done my schooling completely in English so that is the language I am most fluent in, but I also speak German and Malayalam fluently (en leer nu Nederlands). Ever since I was a kid, I have been engaged in a lot of reading and writing (thanks to my dad) and over the years my interest in the field has only grown and hence here I am now - a part of the T-Licht editorial board, hoping to be able to entertain you through the art of writing! I hope you enjoy the many articles in this new T-Licht! Limi Kalapurackal

Relaxation By the chairman

During my years as a student I switched a lot between sporting and drinking beer as my most favorite relaxing activity. During a year as a board member of Japie, beer is present a lot of times and I would like to give you some insights in my experiences. I think the balance between sports and beer is the tool to success. In my first year as a student I studied in Delft and had a lot of fun going out and drinking beers at the bar of the study association. With all of the beers I drank, my sports ambitions were quickly drained and within weeks I went from playing sports four to five times a week to a very nice round zero. At the start of my first year I was very energetic and could focus well on the problems I had to solve. Throughout the year however, I started to have troubles getting out of bed and was nearly always late for my lectures. On the flip side, I did know a lot of people and was very active at my student association. In the end, as some of you know, I sadly failed my year and made the switch to Eindhoven. In Eindhoven the first thing I did was to start playing sports again. It started with once a week but this

soon became two and sometimes four times a week. Besides the fact that I could not stop eating I noticed that I started sleeping less, was more on time for lectures and was able to focus on my studies. Where I wasn’t able to concentrate for 30 minutes before, I could now easily study for two hours. This didn’t mean I was less active at the study association or actively tried to drink less. The parties were still fun and I think I went to Stratum twice a week on average. I combined my sports life with my student life and was still able to complete my first year here in Eindhoven.

“I think the balance between sports and beer is the tool to success.” People like to say that they don’t make the same mistake twice. Guess what, I did. During my year as treasurer of the F.O.R.T. I again stopped my sports activities and repeated the above mentioned spiral. During the summer holiday this year I started sporting again and behold, I experienced the same changes within me.

T-Licht Issue 22.2

To conclude, I found that sports are in my experience really important for your physical and mental health. Most people think that the student life won’t combine with your sporting life or shouldn’t combine. I strongly believe that sporting once or twice a week will greatly improve your overall performance and life experience.

Tom van den Berg As chairman of Japie, Tom would like to share his thoughts on the delicate physical and mental balance of sports and beer in student life.

Science fiction or science fact? Education

When writing this, the first quarter is already over and when reading this, the second quarter is heading to its end. With this fact I’m aware that time is going faster than it seems and that 2030 is heading towards us faster than we think. Although I hope that most of you will not take part in the educational system anymore by then, I think that we will face some changes because of the plans that are being made. Sometimes, it seems that the education at the TU/e stands still. There are still no extra lecture halls and there still is no extra place to study. Therefore, I am happy that I can tell you that the TU/e is making plans about what the university will look like in 2030. There are lots of ideas, some of which I will explain to you. First, the money that the government ‘saves’ by stopping the scholarship and having the feudal system will partly be donated to the universities. The TU/e has plans to invest this

“They think, and I agree with them, that students are learning too much theoretical stuff.” money in the educational system, which seems a great idea to me! The TU/e wants to use this money to hire more student assistants. By hiring more student assistants it will be possible to give education in smaller groups and give individual students more attention. Another idea is the introduction of ‘streaming.’ This means that the lecture will be video streamed online. An advantage is, for example, that only one lecture hall is needed for every lecture that can be streamed, instead of two or three halls with the phenomena ‘live lecture halls’. Next, the executive board is thinking about not only full-time studying, but they are also thinking about introducing part-time studies. With a shorter ‘route’ you will not get the same diploma as a fulltime student, but you will get a diploma with which you can apply for a job.

The last change that the executive board wants to prosecute is that all students will be involved in researching earlier. Now, students are not really involved in doing research apart from your end projects and the TU/e wants to change that. They think, and I agree with them, that students are learning too much theoretical stuff. The plan is to prepare students better for both researching and working at a company. I hope that I have informed you enough about the changes the TU/e is hopefully going to prosecute. If you might have any questions, don’t mind asking me about it!

Noord-Korea Even schoppen

Vandaag in deze rubriek van ‘even schoppen’ gaan we de situatie bekijken in ons favoriete dictatoriale land Noord-Korea! Van intercontinentale ballistische raketten tot moordaanslagen met het zogenaamde zenuwgas VX, Noord-Korea doet het allemaal. Voordat we eens flink gaan veroordelen (lees: Kim Jong-un alle hoeken van het land laten zien), zullen we maar eens kijken hoe het met de geschiedenis van dit land zit. Van 1910 tot 1945 werd Korea bezet door Japan. In die periode werden Koreaanse tradities en cultuur onderdrukt door Japan en werd het land hoofdzakelijk gebruikt om de Japanse economie te stimuleren. Het einde van de Tweede Wereldoorlog betekende ook een einde van Japan als heerser over Korea en het land werd verdeeld door de Verenigde Staten en Rusland (drie keer raden welk deel Rusland kreeg). Dankzij de Koude Oorlog werden Noord- en Zuid-Korea uit elkaar gedreven en begonnen de landen andere politieke systemen en interesses erop na te houden. Ondertussen is het alweer 1950 en de Koreaanse Oorlog is uitgebroken. Nadat Noord-Korea Zuid-Korea

binnen was gevallen, begonnen de Verenigde Staten en China zich ermee te bemoeien. De twee Aziatische landen werden verwoest onder het conflict van de twee grootmachten. Na het einde van de oorlog in 1953 werden de grenzen en de gedemilitariseerde zone wederom opgesteld en begon het conflict tussen het noorden en het zuiden van Korea. Dit conflict heeft zich over de jaren heen geuit als verscheidene moordaanslagen, ontvoeringen van beroemdheden en zogeheten burenruzies aan de grens. Tegenwoordig zijn we meer gewend geraakt aan het testen van ballistische raketten van Noord-Korea en de militaire oefeningen van de Verenigde Staten met Zuid-Korea. Deze situatie

escaleerde wederom in september toen Noord-Korea een waterstofbom testte die vervolgens een aardbeving van 6,3 op de schaal van Richter veroorzaakte. Hoe dreigend is de situatie in NoordKorea nu eigenlijk? Volgens NoordKorea deskundige Remco Breuker valt dit wel mee. “Als Noord-Korea oorlog wilde, hadden we dat namelijk al lang gehad. Het land wéét dat die oorlog namelijk niet gewonnen kan worden.” Noord-Korea stelt zich dus eerder verdedigend op met hun kernwapens, krijgsmachten en raketten. De belangrijkste les is dus: schoppen mag, maar doe het wel met mate.

Like a Jewel wrapped in Gold FoLuCie

Every five years, a lustrum is celebrated among the study association of T.S.V. â&#x20AC;&#x2DC;Jan Pieter Minckelersâ&#x20AC;&#x2122; which brings along festivities, special activities and parties to never forget. But there is another part of Japie that you all know and love, besides its members, books or comfortable couch in the Japie room. Namely the famous F.O.R.T., celebrating its 6th Lustrum year! Letâ&#x20AC;&#x2122;s take a look at how the F.O.R.T. makes their lustrum years extra special!

“Activities that are still being used by the F.O.R.T.-committee to this day. Which ones you ask?” In the very beginning, when the F.O.R.T. existed only ten years, a Lustrum Month was brought to life in order to celebrate this milestone. There was only a month where additional festivities and activities had taken place, not a year! I would like to elaborate more on what actually happened, however time and alcohol may lead to loss of documentation and memories. One side of the F.O.R.T. that will never change: what happens in the F.O.R.T., stays in the F.O.R.T. Only to eventually be forgotten by its guests, bartenders and committees. Luckily, in later years the Lustrum month changed into the Lustrum year that we all know and love today. And with more time, it became possible to allow for more and BIGGER activities to never forget, even after several craft

T-Licht Issue 22.2

beers. Activities that are still being used by the F.O.R.T.-committee to this day. Which ones you ask? Ever since the 5th Lustrum of the F.O.R.T., the variety of activities increased dramatically, as during this year, the term ‘Superdonderdag’ was invented. Four big themed Thursday drinks were organized over the year, with a different theme and even with food. And I don’t mean a hotdog or grilled cheese sandwich that is served every other Thursday. I am talking about sandwich with gyros, or a whole chicken. Naturally, guests would need something to wash it down and quench their thirst after a hard day of study or work. So with the themes

came a craft beer to tag along in the experience. The chicken was accompanied with Weihenstephaner beer, which was a nice play on words on the Dutch word for rooster: ‘Haan’. During Easter, kegs of Palm were imported to the F.O.R.T. for the Palm Easter Drink. Most of the Palm beer was free if you were lucky enough, as guests could win Palm beer (and other various goodies) via a lottery system. A concept that is still being used, like the Oktoberfest we held this year, as the F.O.R.T.-Lustrum committee, which you may or may not remember. The Pantry was transformed into a Bavarian beer tent, with two different Weihenstephaner beers on draft, a typical bratwurst and, of course, a custom made tankard! Another idea came in the form of the Big 25 and the Beer Investment Game, where an activity during one day or evening wasn’t enough anymore. These activities where held over several weeks. The Big 25 was a competition/trial for lovers of craft beers, where 25 selected beers (because of the age of the F.O.R.T.) needed to be consumed by the guests during a Thursday drink, in order to obtain your Beer Drinking Diploma. A small ceremony was held to let everyone know that someone had completed all the beers, along with applause from the audience. On the other hand, the Beer Investment Game included all of the craft beers available in the F.O.R.T. Participants needed to trade in ‘shares’ for several breweries, containing a number of beers. At the end of each Thursday, the general stock was counted and, based on the amount of beer consumed, shares would rise or drop, along with a random chance or event added in for dramatic effect. This meant that all the participants were riling up guests to drink beers, in order to maximize the rise of the shares. This year we organize the Brand Pearl Race, which

combines the Big 30 (we are five years older now) with a cycling based game. Participants have to complete six different legs with five different beers, carefully selected to mimic a real-life cycling tour, in order to take home the prize! So, what are we going to do as F.O.R.T.-Lustrum committee this year? How can we improve on these great activities? Well, this lustrum is going to be bigger than ever before by organizing a craft beer festival on the TU/e campus. These festivals are becoming more and more popular over the years, and every year a large group of Japies goes to visit some of the biggest in the Netherlands. These include the Week of the Dutch Beer in The Hague, the Dutch Craft Beer Festival in â&#x20AC;&#x2DC;s Hertogenbosch, and

many other. Here they enjoy some of the finest beers ever produced, crazy ingredients from which you thought it was never possible to put in a beer, alongside good food and friends. What better to bring this experience to the university for every Japie to enjoy? We plan to make the festival open to everyone, so that you can bring along friends and family. But wait, there is more! The festival will be the biggest activity on the agenda, however we will organize some smaller drinks and activities. Keeping up with the theme of craft beer, there will be a trip to several breweries in and around Eindhoven. A nice warm-up towards the festival. Additionally, why not learn to brew your own craft beer, as we meet up with a professional to learn the ins and outs of the brewing process. Get a taste of what is possible with our own XXX beer in the F.O.R.T., brewed independently at home and soon available for you to enjoy! Not all of our activities will be about craft beers though. This year, the F.O.R.T.committee and F.O.R.T.-Lustrum committee join hands and hijack the DiescafĂŠ during the Dies week, as the board is already busy enough during the birthday of Japie. Traditionally, the beer relay will be present at this evening, but the F.O.R.T. always

likes to play more than one kind of game. We transformed Beerpong into Cannonpong, where you will shoot your enemies into oblivion. Or drink blast your opponent away with Battleships, completing this pirate themed drink. So, we have plenty of activities in store for you during this year and we hope to see you at our activities. Cheers!

Nog goedkoper dan de Action Carte blanche

Een telefoonhoesje voor een euro, een portemonnee voor drie euro en zelfs een tablet voor maar 30 euro. Als je nog goedkoper spullen en hebbedingetjes wilt kopen dan bij de Action of Wibra kun je ze tegenwoordig vrij gemakkelijk uit China bestellen. Onder andere via de webshop AliExpress heb je zo je bestelling geplaatst. Vaak moet je dan wel een maand wachten tot je pakketje eindelijk wordt bezorgd. Maar zitten er eigenlijk nog meer nadelen aan? Er wordt vaak gespeculeerd over de kwaliteit van de producten. Hoe kan het zo goedkoop en toch van goede kwaliteit zijn? De kwaliteit verschilt natuurlijk wel per product, maar omdat je direct vanaf de fabriek bestelt, zijn er geen extra kosten van importeurs of winkels. Deze webshops werken ook met een feedbacksysteem waarbij je wordt gevraagd je ontvangen product te beoordelen. Op basis van de beoordelingen van anderen kun je dus een redelijke inschatting maken van de kwaliteit van het product dat je wilt bestellen. Het tweede puntje is dat je altijd recht hebt op garantie wanneer je in Nederland of binnen de EU iets bestelt. Buiten de EU is dit niet het geval. Op Aziatische websites is erg weinig over garantie te vinden, al zegt bedrijf Alibaba, moederbedrijf van AliExpress, dat producten altijd terug kunnen worden gestuurd en dat ook geld terug kan worden gevraagd. Zij hanteren namelijk een systeem waarbij verkopers via hun website spullen kunnen verkopen aan klanten. AliExpress verkoopt zelf in principe niets. Wel houden zij het

T-Licht Issue 22.2

geld in beheer wat de verkoper betaalt voor een product, totdat de bestelling is ontvangen. Zo garanderen zij dat je gewoon je geld terugkrijgt wanneer je je bestelling niet ontvangt.

“De ontzettend lage prijzen maken het erg verslavend… ” Juridisch gezien sta je echter wel zwak. Als het product dat je koopt niet voldoet aan je verwachtingen kun je natuurlijk altijd proberen met de verkoper tot een goede oplossing te komen, maar zeker van deze oplossing ben je niet. Zelf heb ik al regelmatig wat uit China besteld. Dit zijn vooral kleine hebbedingetjes zoals nagellak of oorbellen. Ik durf nog niet helemaal iets duurs te bestellen, omdat ik bang ben dat het dan toch tegenvalt. Bij een bedrag onder de drie euro maakt dat niet zoveel uit, maar wanneer

je bijvoorbeeld meer dan tien euro betaald is het toch jammer als je niet binnenkrijgt waar je op had gehoopt. Mijn huisgenoten weten inmiddels als er weer een gek pakketje wordt bezorgd, dat ze dat op mijn kamer kunnen leggen. Als je ook wilt beginnen met bestellen uit China, pas op! De ontzettend lage prijzen maken het erg verslavend…

Excursion to BP Japie on tour

After more than six years of studying chemical engineering the inevitable moment has come for me that I have to think about what to do in my working life. The chemical engineer has a few different industries to choose from: chemicals, plastics or the petrochemical industry. To take a look at the latter, a mixed group Japies (because you cannot be too young to think about later) went to the far western end of the Botlek to visit the BP refinery. Among the petrochemical industry in the Rotterdam harbour the BP refinery is known as â&#x20AC;&#x2DC;the traderâ&#x20AC;&#x2122;. This will become clear when viewing aerial photograph of the plant: most of the plant area is occupied by the storage complex consisting of around hundred operating tanks. More storage capacity simply means more flexibility when trading products, hence the nickname. This day something special happened in the complex: one of the tanks caught flame which resulted in an emergency at regional level. Luckily this was just a fire drill, but only simulation already involves a lot of people. Our main host was involved as well and had to leave us a few times for the drill.

T-Licht Issue 22.2

So long for storage tanks. We visited the improvement engineering department, which deals with short term problem solving in the refinery and is also the department were most beginning engineers start. This fall a major turnaround has taken place in the plant and this was used in the case we got presented. Simply stated: after start-up the hydrodesulphurization unit malfunctions and the product is not on spec. The only things handed to us were a few e-mails and some flowsheets.

Developing a new extraction solvent from aqueous solutions PhD article

Deep Eutectic Solvents (DESs) are designer solvents analogous to ionic liquids but with lower preparation cost. Until recently, all DESs were water-miscible, but recently water-immiscible DESs have also been discovered. These hydrophobic DESs have a high potential for recovering molecules from aqueous solutions. In 2001, I started working at the TU/e as a technical assistant in the Process Development group of professor Jos Keurentjes. When he left the TU/e, I continued my work in the Polymer Chemistry group of professor Cor Koning. 2.5 years ago, Professor Maaike Kroon asked me if I was interested in performing a PhD project within the InSciTe Horizontal Project. I had many doubts, but it was a ‘once in a lifetime opportunity’, so I decided to take the challenge. Unfortunately, Maaike left just after I started, but luckily I could continue my PhD under the supervision of Professor Martin van Sint Annaland and Fausto Gallucci.

Biomass Biomass has received a vast amount of attention in the last years, both as renewable raw material and as an energy source. Cellulose and hemicellulose are the macro sugar polymers in biomass that can be hydrolyzed to free sugar monomers (e.g. glucose and fructose), which can be further converted into different platform chemicals. For example, furfural (FF) and hydroxymethylfurfural (HMF) can be obtained by acid hydrolysis of these sugar monomers. FF and HMF are the mostly investigated sugarderived chemicals, because they are intermediates from which many other products can be made, such as monomers for bioplastics. Moreover, they can be obtained from various renewable agricultural resources and residues from forest products. Separations, purifications and solvent recovery determine the economic feasibility of the FF and HMF production processes. The isolation of these sugar-derived chemicals is the main challenge in their production. To prevent their further conversion

through successive reactions, an efficient in-situ separation is required. In my project, the development of novel ‘green’ solvents and their integration in membranes is investigated for the production of FF and HMF from lignocellulosic biomass. The reaction yield and selectivity can be enhanced by the use of a non-mixing solvent for the in-situ extraction from the aqueous reaction mixture. The solvent should be both hydrophobic (immiscible with water) and polar (high affinity for FF and HMF extraction). Most conventional organic solvents do not satisfy these requirements. They are either polar and water miscible, or apolar and water immiscible. Therefore, these solvents either have problems with cross-contamination and large solvent losses, or with very low extraction efficiencies. Instead, natural ionic liquids and their analogues, e.g. DESs, often combine a high polarity with water immiscibility and are therefore very promising new solvents for the in-situ extraction of FF and HMF.

enhanced the transport of FF and HMF through the polymeric membrane support.

DESs are mixtures of at least one hydrogen bond acceptor (HBA) and one hydrogen bond donor (HBD). When mixed in the proper molar ratio, they show a large decrease in melting point compared to the initial compounds (see Figure 2 and 3). DESs are often termed ionic liquid analogues, as they have similar properties to ionic liquids, e.g. low vapor pressure and tunability. Volatility For many applications in separation technology, it is necessary that the vapor pressure of the DES is as low as possible. For example, low vapor pressures allow compounds to be recovered from the DES by distillation without contamination by the DES and without any DES emissions into the atmosphere. It is generally assumed that DESs have a very low vapor pressure. However, almost no vapor pressure data for DESs have been reported. Knowledge of vapor pressure data is also of utmost importance for thermodynamic modelling as well as for comparison of different solvents. This is the reason why we started to find a new method to measure the volatilities DESs. In Figure 4 the vapor pressures of toluene and a hydrophobic DES, which had the highest volatile of the DESs that were studied, are compared. It was found that the vapor pressure of the most volatile DES is 150–1000 times lower than the vapor

vapor pressure, and the difference in vapor pressure with toluene will only be larger. Thus, the vapor pressures of the hydrophobic DESs are indeed negligible in comparison to commonly used volatile organic solvents such as toluene. Liquid-Liquid extraction The liquid-liquid extraction of FF and HMF with hydrophobic DESs from an aqueous environment is extremely fast (equilibrium is reached within 10 s) and the extraction with several DESs is 3-4 times better than with the industrial standard solvent toluene. Supported (SLMs)

Liquid

Membranes

The new hydrophobic DESs can also be impregnated in supported liquid membranes (SLMs). Their recovery would be easier and less DES would be required for FF and HMF recovery. Moreover, a supported liquid membrane reactor would allow for insitu FF and HMF removal, preventing further side-reactions. For the first time SLMs where made with DESs and tested on their performance. High diffusion was reached using supports with larger pores, DESs with lower viscosity and DES, which have stronger interactions with FF and HMF. Thus, the DES can be tuned for FF and HMF recovery. Very promising results were obtained and the addition of the DES significantly

Thus, after two years of research, with the help of many students (OGO groups, ASIA project from Fontys, graduate students), several hydrophobic DESs with three different promising processes for the extraction of FF and HMF from aqueous solutions were found.

In navolging van de

Jumbo Y van de Huismeester

Over Japie kun je een boel zeggen, maar niet dat ze niet creatief zijn. De studievereniging komt namelijk met een soort van voetbalplaatjesboek. Superorigineel natuurlijk, want het laatste jaar hadden alleen de Jumbo, Trekpleister, Leen Bakker en nog zo’n tien andere organisaties dit puike plan. Uitsluitend de tronies van de 66 actieve leden van Japie zullen straks op de plaatjes te zien zijn. Natuurlijk vind ik dit een prachtig idee. Zeker omdat dit concept weliswaar niet nieuw is, maar nog nooit binnen Japie is uitgewerkt. En nieuwe dingen zijn nu eenmaal niet eenvoudig te handelen voor de gemiddelde TUstudent, zoals die er ook binnen Japie veel rondlopen. Bij het presenteren van dit idee, ten overstaan van een haast volle zaal, werd natuurlijk direct de vraag gesteld hoeveel plaatjes er gedrukt zullen worden met de afbeelding van erelid Michael F.J.C. Scheepers erop, vanwege de waarschijnlijke schaarste. Van het verbijsterende antwoord schoot ik spontaan wakker: ‘Michael is geen actief lid, dus er komt geen plaatje van hem.’

Natuurlijk ben ik na het aanhoren van deze mededeling direct vertrokken en heb de toegangsdeuren van de ruimte afgesloten. Witheet heb ik Dienst Huisvesting gebeld en gezorgd dat de inblaas in de bewuste ruimte verhoogd werd van 20,4 graden naar 38,2 graden. Dit zal ze leren om mij geen actief lid te noemen. Ik heb er verdomme voor gezorgd dat de Japiekamer en de F.O.R.T. de afgelopen vijftien jaar volledig zijn ingericht, met de grootst denkbare luxe. Elke vraag die via Japie-leden bij mij werd neergelegd werd direct beantwoord en dit terwijl er volgens mijn baas pas binnen 48 uur geantwoord hoeft te worden. Natuurlijk blijft het hier niet bij en nog dagelijks doet er wel een Japielid een beroep op mij vanwege mijn kennis en kunde. En dan krijg ik

van zo’n opgeschoten jong met een spuuglelijk en veel te kort geel shirt te horen dat ik geen actief lid ben, en daarom geen eigen voetbalplaatje krijg. Dit is voor mij de spreekwoordelijke druppel. Mocht mijn portret niet alsnog verschijnen op de plaatjes van Japie, dan lever ik mijn erelidmaatschap in en ga ik me volledig richten op studievereniging Thor. Die lui van Japie hebben niet alleen een plaatje mét, maar ook vóór hun kop.

Gala Hoe heurt het eigenlijk

On March 23rd Japie’s lustrum gala will take place. For some of you this might be the first gala you will attend and you might have some questions about how you are supposed to conduct yourself during and before such an event. For example, how do you properly invite your date? What should you wear? And how should you behave during the evening? So for this rubric of ‘How is it supposed to be done?’ we thought it would be nice to explain some of the etiquette that apply to a formal gala.

“.. the gentleman should send the lady a letter, which is handwritten with a silver pen on blue paper..” Date When thinking about the upcoming gala, the first thing that comes to mind is that you would like to accompany that one nice boy or girl that’s always walking next to you in the hallway to this gala. However, you’re not sure how to approach him/her to be your date for the gala. Here’s what to do. Letters According to the formal etiquette, the gentleman should send the lady a letter, which is handwritten with a silver pen on blue paper. The lady then answers with a handwritten letter with golden pen on pink paper. In this letter she simply invites the gentlemen over for a cup of tea. However, if the gala takes place during a leap year, the roles switch and the lady should send the gentleman a letter. Tea During this visit the gala will not be mentioned, but the lady should make clear what the gentleman can expect from her and what her intentions are. If she doesn’t serve him anything with the tea, she rejects the request of the gentleman and will not accompany him to the gala. If she serves cookies with the tea, she will accept the gentleman’s request, but he shouldn’t expect anything more. When she serves pie, she is interested in more than just the gala, but the gentleman still has to conquer her heart after the gala. If she serves pie

with whipped cream, it means the gentleman has already conquered the lady’s heart. Color If the lady decides to accompany the gentleman to the event, she should try to make clear what color her dress will be. In this way the gentleman can adjust the color of the corsage to this. For example, the lady could let a small piece of the dress hang from the cupboard or she could place a flower bouquet in the same color as her dress on the table.

Clothing So you are going to attend the gala, that’s nice and all but what will you wear? A gala has a certain dress code which is set by the organizing party.

There are a multitude of options so let us start with the most classic options. White tie This option is the oldest and most formal option for a gala or any officious event for that matter. This starts with the gentlemen, whom should wear a dress suit or ‘rokkostuum’ for the Dutch students. A dress suit has a black jacket with a silk lapel (revers in Dutch). Furthermore this jacket has a longer back then front, which can be executed in the shape of two ‘tails’. Under this jacket is a white waistcoat (vestje) and a starched white shirt with an detachable collar. This goes with high-waist black trousers and the shoes are black patent leather. The outfit is topped off with a white bowtie, which is of course the origin of the name of this dress code. The outfit can be accessorized with decorations, a top hat and/or a white scarf. The ladies have it quite easy when it comes to rules, which doesn’t mean that being dressed to impress is easier though. A proper lady will go with a full length evening or ball gown. They then can accessorize with jewelry, gloves and a small bag or clutch.

Black tie A lot less formal and complicated and on top of that the most common dress code for events nowadays. For gentlemen it is simple, a tuxedo outfit. Meaning a jacket and pants in matching color and material in either black or midnight blue. This is accompanied by a waistcoat or cummerbund (buikriem) along with a white dress shirt and a pair of black patent leather shoes. This is topped off with, you’ve guessed it, a black bowtie. The ladies have some more options when it comes to this dress code. They can wear evening and ball gowns, a cocktail dress and in some cultures even pants with palazzo cut (which is a wide and wavy type of pants). The only classic condition is that the dress is sleeveless and this can be compensated by wearing a wrap or stole. Variations There are organizing parties which misinterpret the black tie dress code. Originally this had an evening dress as only option for ladies with an ankle length for dinner time and a length past the mid-calf at tea time. However, nowadays this is different with more and more variations with the dressing of ladies (and at times men). This is in line with black tie though, since ladies always dressed according to the current trends and fashion within that dress code. So in other words when an organizing party expects a full dress length for ladies with a black tie dress code this should be clearly mentioned. Of course different variations are possible but these should be explained explicitly as well. Corsage When going to a gala in company corsages are an option and certainly an entertaining one. This usually was executed with a flower arrangement but this isn’t specified in any rules. So

being students you can get creative with bottle openers, cards or even walkie-talkies. The only condition is that the gentlemen wear their corsage standing up and the ladies wear it upside-down.

The evening itself Travelling to the gala It’s the day of the gala. The gentleman picks up the lady at her house and greets her with a kiss on her hand, except for when the lady is wearing gloves. The gentleman accompanies the lady to the location of the gala. The lady should always walk on the left arm of the gentleman. An exception is when there is a dangerous situation, then the gentleman walks on the unsafe side. During the evening The gentleman should always let the lady go first. The only exception for this is when using the stairs, in order to prevent inappropriate glances. If the stairs are very steep however, the gentleman should have the lady go first, so that he can catch her should she fall down. Both the gentleman and the lady shouldn’t bring a lot of stuff to the gala. A watch is inappropriate. The gentleman, however, should bring two napkins. One for himself and one for the lady. The lady can bring a small handbag. Dancing If the gentleman wants to ask the lady for a dance, he should make a small bow. If the lady also wants to dance

she nods one time. If she has already promised a dance to another, she can reject the gentleman, otherwise not. The gentleman who got rejected shouldn’t walk directly to another lady, because she might get the feeling to be second choice.

“So, being students you can get creative with bottle openers...” After the gala The gentleman should make sure that the lady can go home with appropriate transportation.

Chemistry

in the bedroom Real life chemistry

According to the internet, an aphrodisiac is a substance or food that is believed to enhance your sexual drive. So, the next time you want to feel extra frisky, why don’t you try something like strawberry, nutmeg or meth? Whether aphrodisiacs really work is debated and one might pose the question: is there any science behind it? The name aphrodisiac comes from the Greek goddess of love, pleasure and procreation Aphrodite. Much like the tales of Aphrodite, the idea that products from nature can stimulate the sexual drive or help along the process of procreation has been around for quite some time. An example of an old aphrodisiac is ambergris, which is a substance that can be found in lumps from the guts of a sperm whale. Although it does not sound very stimulating coming form the guts of a whale, ambergris is used in Arab countries as an aphrodisiac. The ambergris is used in a wide range within folk medicine but it was found that it actually works as an aphrodisiac. The ambrein found in this ambergris increases the

T-Licht Issue 22.2

levels of several hormones including testosterone, which in turn influences dopamine receptors and the sexual behavior. Ambrein also enhances the trafficking within central nerve systems thus stimulating sexual arousal. Apart from ambrein, ambergris also contains ambroxan, which is used in perfumes. This smell might be the reason this application of ambergris was found since a lot of people find certain aromas attractive. An aphrodisiac that is used in eastern countries and dates back to prehistoric times is Bufo toad skin. This contains the substance bufotenine and other derivatives of this substance. This forms the active ingredient in West Indian ‘love stones’ and a Chinese

medication called ‘chan su’. However, it is unknown if this substance actually functions as an aphrodisiac. You might know the toads for a whole other reason though, since the bufotenine and other substances from the toads skin are hallucinogenic. So, these are the toads people lick in order to have hallucinations . Another natural drug that is thought to have an aphrodisiac effect are the kolaand betel nut, which are widespread in Africa, Asia and Latin America. There is no proof for this however, but these nuts do contain carcinogenic substances. While we’re on the topic of drugs anyway, it can be mentioned that a nonspecific increase in sexual behavior occurs when taking drugs that stimulate the central nerve system such as marijuana.

The functionality of aphrodisiacs is broader than just sexual drive or behavior. They are classified into the following groups: libido (sexual desire), pleasure and potency increasing. Potency refers to the healing or decreasing of erectile dysfunctions. Some plants were found that actually do this (within pharmacology). An example is ‘safed musli’, from which the roots are used to cure impotency and generally increase potency. The active substances in these roots are saponins and stigmasterol, which have a testosterone-like effect. Another amazing plant is the date palm which pollen was used to increase the quality of sperm in adult male rats. In this research it was found that DNA errors in the sperm cells even decreased thus curing infertility. These effects are believed to be the result of estradiol and flovanoid components within these pollen. There are a lot more plants with similar effects or other ways to help with impotency, but I sincerely hope that male students don’t have to worry about these kind of medical problems. Some other products from nature weren’t necessarily researched, but are just straight up weird. This includes: cobra blood mixed with alcohol, sliced poisonous blowfish, baboon urine, roasted giant leave cutter ants and sea cucumber. However, none of the products named above were exactly ‘normal’. All those weird products are nice and all but what about something you can buy at your supermarket ? Well, as mentioned in the introduction nutmeg is believed to be an aphrodisiac, which has been studied and proven. Nutmeg significantly increased the sexual drive when tested

on male rats. So this might be a nice spice to try in your food some time, since nutmeg contains alkaloids and sterols that have nervous stimulating properties. Another supermarket product you might want to try is chili peppers . These peppers contain capsaicin that binds to pain detectors for heat. The body will release endorphins in response giving you a relaxed and slightly euphoric feeling, giving its aphrodisiac status.

“So, watch out for any weird stuff.” Pomegranate is another aphrodisiac that was actually found effective when tested on a large group of people, increasing their testosterone levels. Some popular supermarket products that are believed by some

to be aphrodisiacs are chocolate and saffron. Sadly enough, these products were actually found to not necessarily influence the sexual drive. In the end, none of the aphrodisiacs necessarily have a major impact on what people do in the bedroom. Some people spend a lot of time and money to find that one product that will work for them. Not all products are safe and some people even die searching to find the perfect aphrodisiac. So, watch out for any weird stuff . However, the next time you walk into the supermarket you could pick something up, or don’t. You will at least have a lot of random facts to use as a party-trick.

Pre T-Feest diner Met Roos en Rosa Spraakwater

Na de feestdagen is het belangrijk om gezond te eten, maar voor een T-Feest is een goede bodem noodzakelijk. Daarom delen wij vandaag de beste recepten van Roos en Rosa om een wilde nacht te overleven. Dit diner bestaat uit twee hoofdgerechten, een toetje en drankjes. Stap 1: vorm een tweetal en beslis wie Roos is en wie Rosa! Spaghettini met Boerenkoolpesto Spaghettini is dikke korte spaghetti, je mag ook zelf een stukje van de spaghetti afbreken. Verder gebruik je boerenkool, pijnboompitten, knoflook, olijfolie en kaas. Voor de vitamines kies je een groente, bedenk: champignons kunnen Ăłveral bij. Bak de pijnboompitten en doe alles in de blender tot het pesto is geworden. Kook ondertussen de spaghetti. Vergeet niet de Roos uit jullie tweetal langzaam uit te leggen dat je de blender niet al draaiend uit de bak moet halen. Mix de spaghetti en de pesto, strooi er een restje kaas over, haal de groente erbij en eet smakelijk. Drankjes Het drankje om te drinken tijdens deze maaltijd is El Picu Cocos-Spa Fruit. Het drankje moet gemixt

worden door de Roos, de juiste verhouding is half-half (de Rosa kan hier over klagen). RosĂŠ is absoluut verboden!

worden. Even goed mixen en klaar is kees. Belangrijk is dat deze spaghetti met vork en lepel gegeten wordt voor de ultieme ervaring.

Pasta Carbonara Haal voor de pasta carbonara in huis: eieren, spekjes, spaghetti, geraspte kaas, kookroom, een groente naar keuze en natuurlijk champignons. Kook de spaghetti en bak ondertussen de spekjes, champignons en groente in een pan. Terwijl de Rosa aan het bakken is gooit ze de helft naast de pan. Ondertussen maakt de Roos het sausje. Mix eieren, kookroom en geraspte kaas in een bakje tot het mengsel een lichtgele kleur heeft, dit kan op gevoel. Nadat de spaghetti is afgegoten moet direct het mengsel erbij gegooid worden, daarna kan ook het gebakken gedeelte toegevoegd

Overkill Stroopwafelcake Je kan stroopwafelcake maken uit een pak, maar je kunt het ook upspicen. Koop een pot speculoos (die je vervolgens nooit meer gebruikt), heel veel mini stroopwafels en wat speculaas. Doe de speculaas en de stroopwafels in een theedoek en sla hiermee op het aanrecht om er kleine stukjes van te maken. Maak de stroopwafel mix volgens het pak en doe hier alle kruimels en 4 eetlepels speculoos bij. We hopen dat je nog wat stroopwafeltjes over hebt, doe deze bovenop de cake dat ziet er schattig uit. Bak de cake en smikkel. We hopen dat jullie van deze simpele gerechtjes zullen genieten, smakelijk!

Secrets

to making your bike theft proof Carte blanche

It will happen to most of us once in our life. You just had a marvellous time when you arrive at the place you left your bike. At first you look around confused, perhaps you put it somewhere else. However, after a long search you have to admit the inevitable: your bike was stolen. While itâ&#x20AC;&#x2122;s very difficult to make your bike 100% theft proof, you can make it thieves as difficult as possible. Lock your bike Obvious right? Make it thieves even more difficult by using two different types of locks, since most thieves are only specialized in one type. And do not forget to put the chain through the frame and the front wheel. Lock by the valve If you do not want to go through all the trouble of buying a chain lock you can also make sure that you lock your bike close to the valve. This way when they try to break the standard lock of your bike they will most likely also break the valve. Most thieves do not want a bike with a flat tire. Deflate your tire As mentioned above, thieves do not like flat tires. Yes, you would have to inflate it again when you want to use it again, but at least you will most likely still have a bike. Take your saddle Trying to get away quickly on a bike without a saddle is quite difficult. Off course thieves can just steal a saddle from another bike, but you did present them with another challenge. Cover your bike with stickers Did your bike get covered in stickers during the intro? Well, good! You

might have just left them on, because you thought they looked awesome, but they are also a big nuisance for thieves since they will have to take all the stickers off before they can sell the bike again. Color your bike Paint your bike in the brightest colour you can find. A bike that almost glows in the dark is not only a turnoff for thieves, but also makes it easier to spot between all the other bikes. Get an old and rusty bike As a student you do not have that much money to begin with so why not get a bike that is not only very cheap, but is also so old and ugly that thieves would not even consider stealing your bike. Off course you never know how desperate thieves are, but you might actually be glad to be rid of such an ugly thing.

AkzoNobel in the chemical industry Internship report

AkzoNobel is a company that most of you associate with paints, coatings and of course JoZo salt, which everyone can buy in the supermarkets. However, AkzoNobel produces more than just that. AkzoNobel also has a strong B2B integrated specialty chemicals division, which produces chemicals for the paint, pharmaceutical, food, cosmetics and many more industries. During the fall of 2017, I did my internship at the Industrial Chemicals department of AkzoNobel Rotterdam site, in DME Europoort plant. For those who do not know me yet, I am Eline Hermans, an MSMC master student. Early January 2018, I will (hopefully) finish my graduation project, which I am doing in the group of Prof. Emiel Hensen on the catalytic epoxidation of ethylene. Currently, you may know me as a member of the 6th F.O.R.T. Lustrum committee. In the past I had the honor to be a member of the 5th Lustrum committee F.O.R.T. ‘Pie Debye’, 56th board of T.S.V. ‘Jan Pieter Minckelers’ and several more committees within Japie. Before starting to look for a potential internship, I determined my internship criteria. I desired an internship abroad and in a large company. Furthermore, during my graduation project I already got a taste of how PhD life can be. Therefore, to broaden my orientation into the Chemical Engineering profession, I decided to aim for an internship in

the applied chemical industry and not in R&D field. During excursions and at the Bedrijvendagen, I made contact with several employees of different companies. At the Bedrijvendagen I came into contact with Fluor, which offered an all-inclusive internship in the United States. I did not get selected, but it was already a nice way to learn more about myself via their assessments. Furthermore, I got the opportunity to attend two masterclasses, which are a valuable way to network with the employees and get acquainted with a company’s culture. Thus, if you have the chance, apply for a masterclass! Eventually, I selected a few companies to apply for an internship, but almost all could not provide me with an internship abroad. In May 2017 I stopped searching for an internship abroad and contacted the earlier

approached companies again. I got invited for three interviews and got offered two internships. One project I declined, since it was in the R&D department, which indicates the importance of establishing your criteria in advance, and chose for an internship at AkzoNobel. AkzoNobel is a large multinational company, which has their head office in Amsterdam. The company focusses on three business areas: decorative paints, performance coatings and specialty chemicals. Early 2017 AkzoNobel was in the news due to overtake attempts of PPG, a competitor in the paint and coatings business. This led to the announcement that the specialty chemicals business will become a standalone company or will be sold. Thus, this is an interesting time for an internship in that business of AkzoNobel.

AkzoNobel Rotterdam consists of four factories in the Botlek and Europoort. In the Botlek, for example, chlorine, sodium hydroxide and metal alkylates are produced and a combined heat and power plant is operated for the companies at Botlek Business Park. In Europoort there is a dimethyl ether (DME) factory, where I am located. DME is a more sustainable alternative for oil based propellants, which are used in hair and body sprays, air fresheners and XPS foams. In China DME is used as fuel additive and as alternative for diesel engines.

â&#x20AC;&#x153;Thus, if you have the chance, apply for a masterclass!â&#x20AC;? On my first day I was really excited to drive along the highway towards Europoort and see all the plants positioned along the A15. In the following first weeks of the internship, I got acquainted with the reasonably small plant staff (only 18 employees, of which 10 operators divided in 5 shifts) and their individual responsibilities. Together with the process engineers I got a first glimpse

of the plant operation and got to learn what their daily job is like, since I share an office with them. Also due to the chance to join a few shifts I learned a lot about the operation of a chemical plant on a daily basis, how improvements are implemented and what the limitations of the production process are, some of which I got the chance to improve while making progress on my project. For my project I optimized the waste water purification section of the DME plant. During production, water and by-products are formed, which are separated from the product and un-reacted reactant stream and discharged into the harbor. Due to an environmental permit, by-product handling is required before letting process water into harbor, which is done in the water purification section (WZI). One complication is that the DME plant is not operating at full capacity and frequent production rate changes lead to different byproduct concentrations. In the past the WZI parameters were adjusted by the staffs own insights, which caused non-uniformities, often confusions, inefficient use of the purification chemicals and most importantly incidental environmental exceedances. Along my work, optimization was done by a literature study and analysis

of the operation of the DME plant. Furthermore, I updated the manual for operation of the unit. To accomplish my goals, I worked together with all layers of the plant organization, from operators to engineers to plant manager, which I really enjoyed. Furthermore, the theoretical part of the project was right up my alley, since it was more catalysis and chemistry related, which may be a challenge for CPT students. However, the design and general operation part of the project, which should be easier for them, I found a bit challenging. However, I liked the mix between chemistry and chemical engineering and thus challenging myself. Furthermore, I got a good overview on what to expect when I get a job in industry. Therefore, I have decided to leave the academic world behind me as soon as I graduate and apply for a job in industry (possibly even at AkzoNobel).

Gentle fire down your throat Beer of the quartile

After going all the way to Estonia and Sweden for the last beer of the quartile, the stock managers of the F.O.R.T. decided that this time it should take place a bit closer to home. We took that quite literally, because this time the beer of the season is brewed only 1140 meters, as the crow flies, from our faculty, at Stadsbrouwerij Eindhoven. Having just finished the exams of the first quartile, former stock managers Brandon van Rosendaal, Troy Oude Bekke and Guido Hagenaars found their way to the F.O.R.T. again to taste some beers and to decide on the next beer of the season. Of course, good beer needs good food, so we started off with some nice stew to please our taste buds. Once we finished that, it was time for the infamous game of “stock managing”. My first tasting of the beer of the season as a F.O.R.T. stock manager had come to a good start as the beers swiftly followed up one another.

the absolute best was needed. An imperial stout brewed with chipotle named “Till death do us burn” was our undisputed favorite.

Some pretty good beers passed by, but in the end, no argument over

Then comes the taste: sweetness is what absolutely comes across first,

Let’s start with the most important thing: what does this beer taste like and what are its features? Of course, as with every imperial stout, this beer is pitch black. Together with its color, one of the first things that stands out is the viscosity of the beer, which is definitely higher than that of most beers. However, no real surprises up until now, because this is seen for most of the heavier stout beers.

but not in an unpleasant way. At this moment, it does not seem like a heavy beer at all. The softness, combined with the sweetness and some subtle hints of spice come up first. This does not last too long though, because soon the dark character of the malts starts to make its way to your tongue. Also, this is where the contribution of the special ingredient is beginning to be noticeable. During the brewing process, some chili peppers were added to give the beer its spice. Not just regular peppers though, they used the ‘Morita’ chipotle variety. These are Mexican jalapenos that are being harvested when they have changed their color from green

to red (just as with tomatoes). After that, the jalapenos are smoked on a wood fire and are called chipotles. The smoke accompanies the spiciness of the chipotles very well, and that is also exactly what comes forward in this beer by the Stadsbrouwerij. The spices that were in the taste from the very beginning, start to transform into some slight smokiness that the peppers bring with them. Not much after that, the chipotles also start to warm your throat very nicely. Don’t get scared at this point though: just as the brewery itself says, the spiciness stays very much on the background, and this is definitely not a beer that puts your mouth on fire. Maybe that is actually one of the things that is most remarkable about this beer, the brewers could very well have made an immensely heavy, spicy and in-your-face brew with these ingredients. Instead, they made an imperial stout that, despite its ABV of 11.5%, is still very drinkable and does not overdo the smoke or spice to scare away the moderate craft beer enthusiast. The “Till death do us burn” is part of a series of four beers by Stadsbrouwerij

Eindhoven, in which they try to reach for the outer spectrum of malts, as well as experimenting with extended boiling time. In this way, they create these thick and heavy beers, to which they add special ingredients every time. “Burn” is the third in this series of “Till death do us”, and was preceded by the “Roast” and “Smoke” versions. At the moment of writing this article, the fourth and last beer is not yet available, but it is certain that it will be a heavy imperial stout as well.

every beer is top-of-the-bill, but there definitely are some very enjoyable ones that can make Eindhoven proud of its beer culture once again!

Dennis Thuy As the new stock manager of the F.O.R.T., Dennis wanted to share his thoughts on the new beer of the season

The Stadsbrouwerij Eindhoven was only founded two years ago, in order to be able to provide local craft beers to the people of Eindhoven, which had not been the case for many years. By now, almost every person in the city has heard of the brewery, and tasted some of their beers. At the beginning, the brewers started with some of the more traditional beer styles, because their equipment was more suitable for them. Quickly however, they joined in on the craft beer revolution and started to experiment with their beers. Two years on the go, and there already is a very long list of all kinds of beer styles that have their origin in the kettles of the Stadsbrouwerij. In all fairness, not

Celebrating 60 years of Japie Dies week

Every year the week of the 6th of December is a week full of festivities, to celebrate the foundation of our beloved study association T.S.V. ‘Jan Pieter Minckelers’. This year this week is extra special, since it’s the 60th birthday of Japie! But, traditional as our association (sometimes) is, some elements are recurring in our Dies week: a cantus, a diescafe instead of a normal chemiecafe and of course a pub crawl. On Monday, the first day of the dies week, it was a day full with activities! How better to celebrate a birthday than with cake. So, during the lunchbreak on Monday the pantry was filled with hungry and sugar craving Japies to fill their empty stomaches with some nice cake, but only after singing (or shouting?) the Japie song. This year, the ACTcIE got the chance to not only organize one, but two activities! During the afternoon some Japies-soon-to-

be-Sherlocks discovered that the chairman from Simon Stevin had been brutally murdered.

with the committee to Grand Café Centraal for a yummy three course dinner.

Dutchies as they are, the Sherlocksto-be went through town by bike to solve cryptograms and to gain hints and tips about the killer and the murderweapon he or she, or maybe it, used. Unfortunately, no group could solve this intriguing mystery. Solving mysteries makes people hungry, so some Japie members went together

After the stomachs were filled, it was time for the second workshop of that day: Make Your Own Gin, at the bottle distillery in Eindhoven. Of course, it is impossible to make your own gin before tasting some. The group started by tasting the ‘bierbrand’, which is actually distilled beer. By adding some droplets of

water using a pipet (a real one, happy chemists all over the place), the taste and smell of the bierbrand could be enhanced. Next up were three gins, two of which even have one a prize, to taste the difference between several ingredients used in the gin. And last but not least, we got to garnish our own gin tonics by using ingredients like hubiscus, which is used to make it colour pink, or if you’re more up to something spicy, chili peppers could also be used. After the tasting it was time for making the gin! After calculating the wanted alcohol percentage and the amount of water and distills you had to add, one could make their own personalized gin. And again, to the delight of the chemists, we had to use erlenmeyers and beakers. After a great kickoff of the week on Monday by the ACTcIE, it was time to get some more beer involved in the festivities. Together, the F.O.R.T.committee and the FoLuCie put up the diescafé: xXx marks the spot. Traditionally, this pirate-themed evening was all about the beer relays. However, there was more. The committees had upgraded beer pong into a more heroic game: cannon pong, where instead of throwing the ping pong balls, you could shoot them at your opponent in order to win! Besides that, the participants could also have a try to sink their opponents fleet in a game of battleshots. After a thrilling final beer relay, in which the Go-team only just beat Go-team Senior, it was time for the award ceremony. This was the perfect occasion for the FoLuCie to open the ticket sales for their craft beer festival “Het Groene Loper Festival”, taking place in May of next year! A dies week can’t go without the traditional cantus. On Wednesday evening, about thirty participants

came to the F.O.R.T. again to join in singing and drinking beer. The 16th F.O.R.T.-committee were leading the evening as the Praesidium, deciding on all that happened at the cantus. All of the participants sang at their most passionate, and the Praesidium would hand out strict but fair punishments when they deemed necessary. After a great night filled with balloons, bananas, translators and windmills, there was still some time for some beers to soothe the throats that had gone sore from singing. Finally, on Thursday it was time for the grand finale of this already great week celebrating Japie’s sixtieth birthday. Of course there was the Thursday drink, which lasted an hour longer than usual. This meant that after the drink, everyone could immediately get ready for the nights highlight: the pub crawl in Maastricht! The Lustrum committee had prepared an awesome evening from start to end, even with the transportation to Maastricht. Because going by train was a bit inconvenient, and regular busses are a bit boring, the Lustrum committee had decided that the best way to make the trip south was by party busses! As everyone probably knows, going on two party busses with more than one hundred Japies implies great festivities. After some more than an hour of singing and drinking beers on the bus, we arrived in Maastricht. The pub crawl started off at De Twee Heeren, where everyone could get a free shot, and the party got to great heights already. Up next were Café Cliniq and Café van Bommel. Then the party moved on to the last bar

eventually, which was Café Défilé. Of course, the Japies did not tone down as the evening went on, and even though it got late everyone was still enjoying the dancing and the singing. Sadly, all parties come to an end, and so did this one. After singing the Japie song once more at the beloved statue of Jan Pieter Minckelers, it was time to go back on the bus to Eindhoven. Because some people had gotten a bit tired after all, the busses were divided into a party bus and a sleeping bus. After partying or sleeping our way back to Eindhoven, it was time for everyone to go to bed quickly in order to catch a few hours of sleep before the duties of Friday morning would come around already. The short sleep caused a lot Japies to be very hungover on Friday, and for that the board had organized the hangover activity in the F.O.R.T., where all were welcome to hang around on the couch and watch a movie or make something nice with the beads that were provided. Surprisingly, after an awesome week stuffed with Japie activities, many people didn’t have to doubt what they were making: a square lamp is always best!

of energy

Science news

I have always found plants fascinating. Not only do they provide a nice atmosphere for your house, but they are also still the worldâ&#x20AC;&#x2122;s main carbon sink, soaking up CO2 needed for photosynthesis. I understand that the few plants I have, have an almost nonexistent influence on the amount of CO2 in the air. But what if they could provide me with enough energy to power a LED lamp? Or what if the tree outside my house could give me free Wi-Fi? With temperatures rising and the energy consumption ever-growing, finding green energy solutions has become an important goal for many. Using plants as energy source is a concept that has been around for quite some time. Biomass, producing fuel from organic materials, is a relatively well-known subject that has been the center of many discussions. The main problem with biomass is the amount of farmland needed. Farmland that could better be used for food production, since there is still a shortage of food in many parts of the world. Biomass is, however, not the only existing technique that uses plants as an energy source. Plant-e, a Dutch spin-off from the sub-department of Environmental Technology of Wageningen University, has come up with a method to produce energy from plants without actually having to damage the plant itself . They would like to use this method to provide electricity to the poor areas of the world, areas that never had access to electricity before. For this mission Plant-e has won the â&#x20AC;&#x153;Maatschappelijke impact award 2017â&#x20AC;?, which is an innovation price for

social impact. This price has brought new attention to their patented technique that was developed by their CEO Marjolein Helder in 2009. So, generating electricity with living plants. Sounds promising, but how does it actually work? It all starts with photosynthesis, which plants use to produce organic material in the form of glucose. However, plants produce more glucose than they need and the excess is released through their roots into the ground. Bacteria that live around the roots use this glucose and break it down to CO2 and water. The production of water is actually a two-step process. First the bacteria will release a proton and electron, which will then further react with oxygen to create water. Plant-e has developed a way to separate these two steps by placing a membrane, anode and cathode into the ground. The first step of the water production takes place at the anode-side. There the electrons will flow into the anode and are transferred to a power-harvester after which they will continue to the cathode where the electrons flow back into the ground. At the

same time, the protons will have diffused through the membrane to the cathode side where step two of the water production takes place and the circle is closed. This process will produce electricity 24/7 and will only temporarily stop when the system is completely frozen . Using this method Plant-e can generate energy anywhere where plants can grow and water is abundant available. This means wetlands or watery fields such as rice

paddies would be ideal locations. All of this does mean that this process is not suitable for dry areas since it would use up too much water. Since it does not matter for the process if the water is polluted, this method would similarly be well suitable for areas that are too polluted and therefore unsustainable for growing crops. Looking at China, where land the size of Belgium has been categorized as being too polluted for farmland, this technology could kill two birds with one stone. It could be a new source for clean energy, while also helping reforestation in parts that cannot be used for farmland.

efficiency. Currently, Plant-e is able to produce 1 watt per square meter, which is relatively low compared to solar cells that on average generate around 150-200 watt per square meter. Plant-e believes that, if they can increase the power to 3 watt per square meter, they should be able to

“Will the tree outside your house provide you with the energy needed for your Wi-Fi in the future?”

Will the tree outside your house provide you with the energy needed for your Wi-Fi in the future? It is definitely a possibility and having a garden on your roof would certainly look nice. Perhaps we will all start planting like crazy if it could provide us with energy. Most importantly Plant-e shows that it is possible to come up with creative solutions for green energy that are not just an improvement of an existing technology. Let’s now hope that with all these ideas we are finally able to increase the amount of renewable energy, because drastic measures are needed if we want to meet the goal set by the Paris Agreement of keeping the global temperature rise below 2 degrees Celsius.

Written by:

While this all sounds very promising, Plant-e’s technology is not yet suitable to be incorporated into existing wetlands. Currently the process is only used in closed plant boxes in which Plant-e creates an ideal environment. However, they are working on a system that is not restricted by these boxes and that can be applied in a fresh, salt and brackish environment. Nevertheless, the main drawback of this process is still its

power the average Dutch home with 125 square meter land, which is the average size of land for a Dutch singlefamily home. So perhaps instead of building solar panels on our rooftops we will start building rooftop gardens. At the moment this is still a dream of the future, but Plant-e is currently working on a number of small-scale projects and they are actually able to power most of their main office using their technology.

Als procestechnoloog ben je breder inzetbaar dan je denkt Van de donateur

Een artikel schrijven voor het T-Licht, hĂŠt verenigingsblad voor Scheikundig Technologen, terwijl je zelf eigenlijk nooit als Scheikundig Technoloog hebt gewerkt, is dat nou wel zoâ&#x20AC;&#x2122;n goed idee? Juist wel, bedacht ik na een aantal dagen, want hoe kom je nu als procestechnoloog in een heel ander vakgebied terecht?

Ik heb bijna 8 jaar rondgewandeld op de faculteit. Best lang, maar zeker niet té lang. Met een jaar bestuur van Japie en allerlei mooi commissiewerk ernaast is de tijd omgevlogen. Bovendien moet ik de eerste recruiter die daar moeilijk over doet nog tegenkomen, die extra ervaring wordt juist erg gewaardeerd. Dat is dan ook meteen de eerste manier om ervoor te zorgen dat je ook interessant wordt voor andere functies dan alleen die van procestechnoloog. Een tweede manier om breder inzetbaar te worden, is te beginnen als (strategie) consultant. Je ziet veel verschillende bedrijven van binnen en leert in korte tijd heel veel nieuwe dingen. Het mooie is dat strategie consultants 30 tot 40% van de new hires bij de technische universiteiten vandaan halen, omdat die goed zijn in het gestructureerd aanpakken en oplossen van problemen. Omdat je als Scheikundig Technoloog niet heel veel financiële achtergrond hebt, op een keuzevak bedrijfseconomie na, ben ik in 2011 met een opleiding tot registercontroller gestart in Maastricht (ja, in de stad van onze Jan Pieter). Zo’n opleiding na je master is dus nog een derde manier om de

Op dit moment werk ik bij ASML, waar ik samen met 10 collega’s de twee presidenten en de Executive Committee help om de strategie uit te voeren, goede besluiten te nemen en veranderingen in de organisatie door te voeren.

uitdaging is. Veel nieuwe dingen opzoeken en uitproberen is daarmee de laatste tip om als procestechnoloog de breedte op te zoeken. Ik zou niet meer aan de slag kunnen in de procestechnologie en toch ben ik er elke dag mee bezig. Als teams te weinig output leveren, moet je soms de druk opvoeren of verstoppingen weghalen. Als twee mensen niet zo goed met elkaar samen kunnen werken, moet je soms wat verwarmen, roeren of een katalysator toevoegen om de chemie op gang te brengen. Tot slot kan het bij elkaar voegen van zeer verschillende teams soms tot exotherme of zelfs explosieve reacties lijden. Safety first geldt dus ook voor bedrijfsprocessen!

Living the PhD life Culture shock

After three years of bachelor courses in my beloved Brabant I felt the need to challenge myself and go on an adventure abroad. I ended up doing research on polymer chemistry at the University of Warwick. While suddenly being all alone in England was a larger culture shock than I had imagined. I definitely enjoyed starting from scratch and building up a new life in this marvellous country. Even before my first workday I was invited to a kick-off party at prof. O’Reilly’s place to initiate a new academic year. From that moment on I was warmly received in the research group and put on equal ground with the PhD’s and PDRA’s. I liked that just like them I’ve got my own desk, had to present my work and chair group meetings. Their enormous drive and diligence had a positive impact on me as I went with the flow working from 9 till 7. I genuinely felt like I was a part of this prestigious paper producing machine. The main campus of the University is lively and in contrast with most

British universities futuristic. There I joined the students tennis club, watched movies in the art centre and even went to parties. Unfortunately my requests to live on campus were declined and therefore I had to find shelter in Coventry, a city that’s an one hour bus ride away. Coventry once was a prosperous industrial city being home to Jaguar, Land Rover and a large scale weapon production. The latter was a good reason for the German Luftwaffe to bomb the city to the ground in 1940. Nowadays Coventry is best described as a ‘melting pot’ which is especially true for the poor neighbourhood I ended up in.

Luckily the house I lived in was fantastic and my fellow Erasmus student housemates were nice as well. Especially with my Italian friend Francesco I spend hours in the kitchen learning how the make ‘real’ risotto, avoiding the English food as best as we could. Don’t get me wrong, the breakfasts, high teas, pies and Sundays Roasts are delicious. But the dinners they serve consist mostly of glorified fastfood. It’s better to make your own. Whereas my time was dedicated to work during the weeks, I was completely free in the weekends. I’ve taken great advantage of the central location of Warwick and travelled to Birmingham, Stratford-upon-Avon, Southampton, Winchester, London and Liverpool. So In the end I would say that I’ve learnt a lot about British culture, chemistry and myself during this special placement.

De sjaarzen-immigratie Even schoppen

Elk jaar een terugkomend, maar niet minder ernstig probleem: de sjaarzenimmigratie. Behalve het feit dat dit een jaarlijks terugkerend fenomeen is, lijkt dit fenomeen de afgelopen paar jaar gegroeid te zijn. Waren er 7 jaar geleden nog ongeveer 1000 sjaarzen, tegenwoordig is dit aantal verdubbeld en lopen er 2300 frisse nieuwe studenten op de campus rond. Natuurlijk is het hartstikke mooi dat veel mensen een technische studie doen en nog mooier is het dat deze mensen dan voor het prachtige Eindhoven de gekste hebben gekozen, toch zijn er ook wat mindere kanten. Allereerst, een nieuw fenomeen dit jaar: de Swapfiets. Tijdens de intro waren zowel de campus als het stadscentrum overspoeld met oranje, blauwe, rode en zwarte exemplaren. Hoe mensen ooit in ietwat beschonken toestand hun fiets teruggevonden hebben in deze zee van Swapfietsen is voor mij een raadsel. Helaas bleef de toestroom van Swapfietsen niet beperkt tot de laatste week van augustus, ook in september was de campus nog

behoorlijk oranje en blauw gekleurd. Aangezien ook de sjaarzen zonder kamer tijdens de intro een fiets nodig hadden, en ze de huur van deze fiets in september er gratis en voor niets bij kregen, stonden er in september heel wat Swapfietsen de schaarse fietsenstallingruimte in te nemen. En bedankt, Swapfiets . Als ze nu eens opschieten met de verbouwing van de Matrix, dan hoef je er niet meer voor 08.30 uur te zijn om een plaatsje voor je fiets te bemachtigen. Ten tweede heb ik dit jaar ook voor het eerst in de file gestaan om de campus op te komen. Een fietsersfile wel te verstaan. Ik heb al lang niet meer voor 08.45 uur op de uni aanwezig hoeven zijn, maar

wanneer je verplicht college hebt, is het natuurlijk wel handig om er op tijd te zijn. Helaas waren er nog meer mensen met dit goede idee, met als gevolg dat ik met mijn goede gedrag al stil stond voordat ik Ăźberhaupt de campus op gefietst was. En te zien aan de hoeveelheid sjaarzen-tassen en Swapfietsen, is ook dit grotendeels toe te schrijven aan de sjaarzenimmigratie. Dan het laatste knelpunt: pauze houden in de Helix. Wanneer je zittend pauze wilt houden rond de tijd dat je honger hebt, vaak toch wel tussen 12.30 en 13.45 uur, dan kun je dit mooi vergeten wanneer de sjaarzen in de Helix college hebben. Of dit komt doordat er teveel sjaarzen zijn, of omdat de kantine te klein is, is natuurlijk een goede vraag, maar als oplossing kun je nu gelukkig ook je lunch aan een statafel nuttigen.

Better too be early... Or maybe not? Letting off some steam

I’ve always been someone who doesn’t like to be late. Because I’m a bit impatient, I also don’t really like it when other people are too late. That’s why I always try to be there a few minutes before the actual meeting time. I used to say: ‘Better too early than too late’. However, due to some annoying events, I’ve lately started to believe that this is not always the case. A few weeks ago, I had to go to an important meeting in Utrecht. I was going by public transport and had to take the bus to the station. I made sure I was at the bus stop a few minutes before the bus would leave. However, when I was approaching the bus stop, I could see that the bus was already at the bus stop. I started running, but I was too late. The bus was already leaving. I missed it, which also made me miss my train and caused me to be late for my appointment. The bus was too early, which, in this case, was not better than too late. A week later I ordered cycling shoes and I needed them the next day. The tracking details said they would be delivered between 17:00 o’clock and 19:00 o’clock. I went for a run and at

16:15 and I thought I still had enough time to take a shower. When I was in the shower I heard the doorbell ring, but just thought it wasn’t for me. After I got out of the shower I found a note in the mailbox, saying that they had tried to deliver my package, but nobody was home. They would try to deliver it again the next day between 16:00 and 18:00. I had learned from my mistake and was home one hour before the package would be delivered. Well, that was just on time, because at 15:15 I heard the doorbell ring and my package was delivered. The deliverer was way too early again, another example where being too early is not better than too late.

“In conclusion, to outrun any misery, the best thing to do is just to always be right on time.” Of course, if the bus had been too late I might also have missed my train, and if the deliverer was too late I might not have been home to accept it as well. Being too early isn’t always a good thing, but the same goes for being too late. In conclusion, to outrun any misery, the best thing to do is just to always be right on time.

Interview with dr. ir. Ivo Roghair Interview

Ivo Roghair is an assistant professor at Eindhoven University of Technology since 2013. He currently teaches the courses “Numerical Methods” and “Practicum Process Technology” in the Bachelor phase. For his outstanding teaching methods he was granted the “Bachelor lecturer of the year” award last September. Let’s start with your professional background, where did it all start for you? I studied Chemical Technology in Twente and I graduated in the group of prof. dr. ir. van Sint Annaland and prof.dr.ir. Kuipers when they still worked there. I graduated on the subject “PIV/DIA” which is an experimental method to make photos of a fluidized bed with a high-speed camera. This is used to get more insight in the velocity of the particles and the behavior bubbles. After my graduation, I did my PhD there as well. During my PhD the group moved from Twente to Eindhoven. After this PhD, I did my post-doc, which was in Twente again. Then Martin (van Sint Annaland, red.) asked me to fill

up a vacancy in his group Chemical Process Intensification in Eindhoven. I applied and had a job interview. I was picked to fulfill the position and now I’ve been working here in Eindhoven since 2013. Knowing the numerical models and experimental techniques was an advantage for me as well as for the group. During the start of this year, you got an award for being the best bachelor lecturer on the university. How do you see yourself as the best lecturer? It is always a bit weird, since I was proposed by the students. It would make more sense to ask them why they picked me. Of course, I do have an idea, because the Rector Magnificus said during the award ceremony that I taught my students how to make crystal meth during the course “Numerical Methods”. This is obviously not true, but I did make the assignments in such a way that it was relatable, applicable and fun for the students to work with. I put a lot of effort and time into these assignments and I think this helped in making the students more enthusiastic for this course. This helps showing what the course is applicable for. I want to show that small physical problems can be extremely interesting to dive into. The trick is to make students

aware of the fact that a lot of the things around them can be explained or solved with numerical methods. A good example of this is one of the assignments on the classic double pendulum. The random motion it exhibits is a basic physical principle, but being able to create it yourself and seeing the output on a screen, helps students to stay motivated and solve these kind of problems. How did you learn to be such a great lecturer? I did my UTQ: University teaching qualification, so of course I learned a lot there about teaching and learning in higher education. Also I looked a lot at my own former teachers and lecturers, e.g. the courses I took over from dr.ir. Van der Schaaf and Prof. dr.ir. Zondervan. These courses were already in good shape, but I gave them my own twist. Also, as said before, I put a lot of time and effort into my courses, so that helps a great deal as well. What achievement in your life are you most proud of? The combination of my academic career, the award, but also my PhD, and my personal life. I’m really satisfied to have a nice balance between my job and my family, with my wife and two kids.

How do you spend your spare time? My work is an important part of my spare time as well, as I like to program and write scripts as a hobby. Also, I’m busy with my kids, building with LEGO Duplo or watching “Buurman en Buurman” and that can be very inspiring as well. My personal hobbies are photography and videogames. I have a PlayStation 3 and I love to play games like GTA V or Cities: Skylines. The problem is I really have to find the time to play a game. This of course is the same for photography. I mainly enjoy architecture and natural life. It works best if you go out into nature for a few hours and try to get the best photo. I’d rather take three hours to photograph a sparrow on a branch, than just go to a zoo and take a picture of a lion. Was being a teacher always your dream job? Actually it was not. When I was a little kid, I said I wanted to be a teacher in elementary school, but this later changed. I wanted to be a pilot or a surgeon. To accomplish this, I applied for med school, but I didn’t get in. Then I chose to study Biomedical Engineering as a way to get into med school. In my first year, I had to follow Chemical Technology and I forgot that I wanted to study something biological. I got in touch with the beautiful chemical processes and just never left. The switch wasn’t that strange though since I always enjoyed programming and even considered studying Computer Sciences. This also comes back in me enjoying numerical methods. Do you have any ambitions to become the best teacher in the master phase or even the Netherlands? Yes of course! I honestly don’t know how you enroll in such a competition,

but of course I would really enjoy the appreciation of the students for my courses. I feel like I want to reach for a certain standard and that the students see why the course is so much fun. If the opportunity comes along, I would love to become an Associate Professor or give a course in the master. Do you have big plans with the € 5000,- you won alongside with the award? In the Cursor I said I wanted to buy a PlayStation 4, but they told me I should spend the money on educational purposes. Don’t worry though, the PlayStation 4 will come! I’m still doubting where to spend the money on. ESA gave me the option to take a course for myself to improve my skills as a teacher, or to spend it on the course. For numerical methods this is hard, since I only need a laptop and the Matlab licenses are already bought. I might look for a student assistant who can help me making the exercises, or maybe it would be possible to go on a fieldtrip or something. For the practicum it is also hard, since we recently got a new set-up, and with €5000,- I would be able to buy one new mass flow controller so it wouldn’t change that much. Luckily I still have a lot of time to consider what I want to do with it.

Dilemma’s Research or education Education Interactive lectures or guided selfstudy Interactive lectures Lecture at 7 a.m. or lectures at 7 p.m. That’s a though one! I’d go for the lectures at 7 p.m. since we have a lot of students who don’t live in the city, so they won’t be able to make it to the lectures at 7 a.m. But only if the university will provide pizzas and beers though! Twente or Eindhoven Ah that’s a conscientious question! For the university I’m going for Eindhoven, but the area and surroundings of Twente I like much more. A final advice for our readers? Don’t be afraid to get distracted! I like to play videogames when I have to work, but it is a great way to reset your mind and get your focus back.

Language barriers Letting off some steam

I have always been aware of language barriers but I had my first real big struggle with it recently. The puzzle of the last edition was originally my responsibility but I made a mistake and made a Dutch one. When I tried to translate this cryptic puzzle to English it just resulted in a big mess. So with the bachelor now being in English too I wanted to look into and discuss the struggles with language barriers in everyday life.

Sayings Let’s start off with a classic: sayings. In the Netherlands there is an entire Facebook page of pictures describing situations in English with the most horrible, cringe-worthy and hilarious translations of Dutch sayings. So in order to get any international reader on track with me I’ll list a few. It’s raining pipes-stems , which comes closest to the English saying “It’s raining cats and dogs”. Looking the cat out of the tree, which is comparable to “waiting it out”. Or you bake nothing of it what just means you’re doing bad at what you’re doing. I could go on and on but that would just turn this

article into a list of Dutch sayings in English and some poor explanations of them.

Humor Another thing that is really hard when using another language is being funny. Because cracking a joke in another language can be quite a challenge. I think that all international students get this since a lot of Dutch students tend to make a quick regard or joke in Dutch in a fitting situation. However, this makes that any nonDutch speakers will just be sitting on the side-line in a somewhat awkward fashion until somebody translates or explains the situation.

Foods Foods are a personal pet-peeve of mine when it comes to other languages. Some vegetables for example have quite different names in English. Some names I have struggled with are zucchini (courgette), eggplant (aubergine) and arugula or rocket (rucola). And then there are the Dutch foods that simply don’t have a name in the English language like ‘hagelslag’ or

T-Licht Issue 22.2

‘chocolade vlokken’, ‘drop’ which you probably won’t like if you’re foreign and ‘stroopwafel’ which you will like. By the way, if you haven’t had ‘stroopwafels’ yet, why are you reading this? Go get your priorities straight! As a closing statement I would like to mention the platypus, which is an awesome animal. But in Dutch it’s called ‘vogelbekdier’ which is ‘birdbeakanimal’ when you do a literal translation.

Expedition On campus

After spending around a quarter of my life here on the campus of the TU/e, one would think that nothing on this campus surprises me anymore. While this might be true for the bigger part, the TU/e hides some public secrets in the far reaches of its campus. Since I didn’t find out about some of the following campus features until my student life here was well established, my thoughts were to share some of these secrets to speed up the process for you. Let’s start with some bare necessities for living anywhere in the Netherlands, a bike. Even though the campus does not sell bikes per se (don’t steal any please) it has always featured some form of a bike repair shop. In my freshmen year this shop was located near the SSC (see map [1]) and was pretty hidden for my taste. After this shop shut down a while ago, the bike shop has taken on a more mobile form. This mobile workshop is available from 12:00 to 13:00 on weekdays except Wednesdays for anyone missing the old services [2]. Next up, a more basic necessity for healthy living: food. The campus actually features a community garden

since 2013 [3]. The garden grows fruit, vegetables, experiments with any plant that can be called edible and many other so-called forgotten vegetables. Unfortunately I can’t tell you what these forgotten vegetables are. I might have forgotten. During the winter this spot might look like a glorified cabbage patch, but I implore you to just sometimes take a peek during summer to see what’s growing. It might bring some fun into your trip to and from Paviljoen. If any of you have ever seen the community garden, one shape in there might actually look really familiar. This dome shape looks like a small replica of the aptly called ‘Koepel’ (or Dome in English [4]) that can be

found at the farthest eastern corner of the campus. This dome is a huge structure that has long been used as a building ground for the faculty of Mechanical Engineering. Whether it still serves this purpose, I don’t actually know but the impression I got when visiting this structure recently was more one of dilapidation than of innovation. Another thing that struck me during my visit was that I had actually been there many years ago (six to be exact) during a fire safety course given by the on campus fire fighters. Fun times. I could go on about many, many more public secrets like the announcement board in IPO [5] that frequently features pays for human test subject (usually harmless and very simple) to the day care center that is situated right next to the bar of a study association [6] but some secrets are way more fun to discover yourself.
