TU/e involved in major test with electric cars

Monday 6 January - Temperatures in the Finnish town of Juuka are barely sub-zero, but the giant igloo TU/e students plan to build will be realized anyway, says lecturer Arno Pronk (Built Environment), who’s supervising the Pykrete Dome project. The team hoped to start on the actual construction of the dome with a record diameter of thirty meters this Thursday night.

According to forecasts, temperatures will drop to -12 and even -20.

TU/ecomotive to develop practical and comfortable city car Wednesday 18 December - A practical, comfortable, and energy-efficient city car, cheaper than the Renault Twizy - it’s how TU/ecomotive describes its second electric car, which will be taking part in the Shell Eco marathon in May. The students are aiming for full approval of the car by the Dutch RDW, so their EM-02 can hit the Dutch road officially.

New Year ‘Special’

“Happy New Year everyone, and welcome to 2014!” The announcement was followed by the most amazing fireworks I’ve ever seen in my life.

Millions of people had been standing by for four to five hours to witness this moment. As the clock struck twelve, people popped bottles of champagne, shared them with strangers, and wished everyone the best.

The moment felt very special and heart-warming to me - happiness and love were in the air.

The night’s celebration ended, we came home, slept, and got up again for the New Year’s Day out. My family believes that whatever you do on New Year’s Day reflects what you’ll be doing the rest of the year! And since I don’t want to be lazy for a whole year or want to spend it sitting at home, going out was the only option, despite the bad weather and being tired.

We concluded the day with a temple visit and a dinner outside. I was happy; the year had started well.

Then I thought: what has started, really? Nothing in my life ended on the 31st, nor did anything start on the 1st. I knew exactly what was waiting for me a few days back. Whatever I didn’t know then, like what I’ll be doing after I’ve graduated, I still don’t. It’s safe to say the arrival of 2014 hasn’t changed my life dramatically.

Yet we all love to celebrate and welcome the new, no matter how insignificant its influence. You might feel the New Year calls for resolutions and presents an opportunity to reorganize your life. If that’s what you did: wonderful.

If you didn’t, why not consider today to be a Special New Year’s Day, just for you?

And how are things in Loughborough?

More and more TU/e students go abroad for their studies to follow courses, internships or a doctorate path.

What is it like to find your way in a new country? Students tell their stories.

L’boro, Lufbra, and Lovebro are just a few ways to talk about the university I’m studying at as an Erasmus Exchange student. In this town, one thirds of the population consists of university students: fifteen thousand in total. Loughborough University isn’t renowned for its research, but rather for its athletic successes. For the past 33 years, they’ve won the BUCS (national student sports competition), and last year more than forty of its students competed at the Olympics in London.

The athletic possibilities at Loughborough are endless, and that was one of the reasons that made me want to go and study in England. I can choose to train between athletes that are among the best in the world in athletics! Apart from sports, I’m also working on my academics, of course: right now, I’m studying water and sanitation management in developing countries. In the courses I work with students aged 22 to 59 from Japan, Nigeria and the USA, to name but a few countries. Many of them have gained international experience, and have been to countries like Haiti, Pakistan and South-Sudan.

It’s a varied mix of people that can definitely teach me a lot.

After having spent three months on campus among six thousands students I’ve come to realize some of the prejudices about the English are true. They always think it’s summer, or at least they dress as such, and drinking is all about taking in as much alcohol as you possibly can - vomiting certainly isn’t a crime at our campus.

Still, there may be more to English students than meets the eye. Many of them volunteer and raise money for charity. Unfortunately, this year Loughborough’s students gained notoriety for a video that was uploaded to YouTube in November. Arguably, it’s ‘the worst YouTube video ever’. I’ll let you be the judge: http://tinyurl.com/qduwoad.

Life after TU/e

Name: Orlando Méndez Morales Place of Birth: Tlaxcala, Mexico Date of Birth: 17 July, 1977 Studied at TU/e: October 2007 - November 2009, joining the PDEng program in Software Tecnology (OOTI) Current position: Software analyst for financial services company Experian in Chili How did you reach your current position?

I started looking for a job already in the final phase of my degree project in 2009.

I was offered a job by Sioux Embedded Systems that year, but owing to a slow and inefficient migration process, I couldn’t start until October of 2010. My working relationship with Sioux lasted almost two and a half years. From 2010 to 2013, I’ve worked for different high tech companies (FEI, TomTom, ASML). I went back to Chili in May 2013, and was hired last October eventually. I’m now a software analyst for a financial services company called Experian. So far, I enjoy both what I do and the international working atmosphere.

Why did you go to Chili?

Although we considered staying in the Netherlands, my wife and I realized that would make it very difficult for her to develop professionally. And for me, the pressure of having to make do with just one income for a family of five was too much.

A risky single-point-of-failure, to put it in engineering terms. That’s what motivat ed us to return to Chili, where my wife is from.

Why did you go to TU/e and how do you look back on your time there?

It was the result of the contacts I made at TU Delft, where I did a Master’ s in Computer Science between 2002 and 2004. My thesis advisor, Professor Arie van Deursen, happened to know Harold Weffers, the OOTI program manager back then. A four-year PhD program didn’t sound very appealing to me, but I was excited about the two-year OOTI program. In general, it’s been a pleasant and demanding two years.

I was already married and had children when I joined OOTI, so the combination of private life and the student/working life required some juggling.

What happens to international students after they graduate from TU/e? Do they go job hunting in the Netherlands, pack their bags and explore the world, or return to their home countries? International TU/e graduates talk about their lives after TU/e.

What advice would you give current students?

My advice is that they should never stop pursuing their dreams. The very fact somebody dares to go for a degree in higher education says something about importa nt personals characteristics that go beyond a high IQ. To achieve your goals, you have to sink your teeth into them. Every student is in charge of the course of their (profess ional) life.

I trust their TU/e degree will provide the tools that are important in order to become successful, world-class engineers. Today, technological and econom ical changes are hard to keep track of, so it’s all about seizing opportunities, no matter what part of the planet (and perhaps in a few decades, the universe) they appear.

I appreciate readers’ reactions to this article, so feel free to drop me a line or two at mmoa33@hotmail.com. I’d be happy to read your comments.

Abo and

The New Year’s reception. That peculiar meeting at the beginning of the year. The morale of the troops is raised by a pep talk of the Executive Board. Smack kisses and half-kisses fly around, while some guests make do with feeble handshakes. The ideal indicator of mutual relations.

For Rector Hans van Duijn the half-empty glass that long threatened to characterize 2013 turned into a cornucopia yet. Successes in the intake, the Institutional Assessment, the Gravitation Grant and the solar-powered car in Australia turned the tide just in time. This has also considerably improved the prospect for the new year. Which is even more noticeable with the business community taking an active part in the creation of 250 extra doctoral candidate positions. The full glasses of Prosecco that were raised to celebrate this were emptied avidly.

A veritable audience circus formed itself around the new Executive Board President, Jan Mengelers, the TNO executive who will on March 1 join TU/e.

The amiably smiling newcomer was almost constantly surrounded by a cordon of men in very smart suits. Rector Van Duijn, every inch the chaperone, hardly moved from his side.

In a year the search for the Rector’s successor will also commence.

Compulsory attendance? | A must - that is how André Snoeck, a student of Industrial Engineering and Management Sciences, characterizes the meeting in the Senaatszaal.

Which means: especially in his capacity as spokesman for the Solar Team Eindhoven.

“I find it important that we put in an appearance here, but I also want to hear what things TU/e is involved in.” Still, honesty compels him to admit: “Personally, as a student, I would probably not have gone to this event”.

Close by some fellow students are hanging over a high table. Most of them are committee members of study association Industria, for that matter. Treasurer Debora Katerberg finds the New Year’s drink “a cozy event” at the beginning of the year to meet other people and to hear something about the university’s plans. Industria colleague Maarten Koek: “It’s nice to hear what the university achieved in the past year. You wouldn’t be hearing a lot about that otherwise.” He did pick up on the advent of a new Executive Board President, though, “but I do appreciate the Rector adding some personal notes to this”.

Although Marguerite de Faber has worked at the university for many years, she has barely any recollection of her latest attendance at the New Year’s reception. Last year she switched her many years’ departmental job for a new one at the Education and Student Service Center (STU). And she realized: “Departments are genuine islands. Now, at STU, I get to meet many more people, who come from all across the university. I feel more a part of the greater whole”.

José Leonardo Ferreira is feeling predominantly positive - which is in line with the Brazilian’s nature. “A new year is always a good thing, and it’s important to share that good feeling with others”, is how he accounts for his presence. That the Rector’s New Year’s speech was in Dutch -and hence a bit difficult to follow for the doctoral candidate at Electrical Engineering is something Ferreira shrugs at. Being together, that’s what it’s all about. “I’m a social person anyhow, but in addition I am and explicitly feel part of the university. Coming together here gives me positive energy.”

out half-empty glasses full glasses being emptied Knowing the customer’s wishes | During an interview with Anneke Michielsen at the bar, a special spectacle unfolds. The supervisor at Eurest sees people approaching and has the desired drinks standing ready even before people can order them. “They’re there for you”, she says to a man who is coming to get some beers. “I really go after that, to know the favorite drinks of as many people as possible. It makes them feel welcome”, says Anneke, who is taking care of the New Year’s drinks for the 27th time.

“I also know the favorite drinks of the Executive Board members, and though I don’t know this for the new President, I’m going to find out soon enough.”

Anneke is a familiar face at drinks and vice versa.

“I think I know about 65 percent of the folks here.”

And everybody knows her, for between times she wishes lots of people Happy New Year. And they know precisely where they are with her. She quickly slips a former staff member who has become homeless a bite-sized croquette. “Have an extra one.”

De exit-poll | The first one to sneak away from the New Year’s meeting is prof. dr. Sjoerd Romme. “I have a meeting at the University Club at five about the redesign of the major of Industrial Engineering and Management Sciences. While I like the congeniality of this drink, I don’t need it to maintain or enhance my network. I talk to these people quite often anyway.”

He has a good feeling about it. Whether the Rector’s jokes during his speech also made him laugh seven times, like most of the audience? “I did smile.”

Lecturer trainer Esther Vinken is leaving the drink because she wants to be with her family for dinner. “I really think such a drink is great. For me it’s an opportunity to talk to people.

As TU/e colleagues you lose touch briefly during the holidays. Here I plot the course again.

I purposefully spoke to fifteen people, also to confirm what we agreed on last year.”

Drinks and students | A sip of champagne (or Prosecco) to mark the new year. In theory this could have been an illegal activity for some of the people attending this New Year’s drink.

After all, since January 1, minors cannot drink alcohol anymore, and every course has some first-year students among its numbers who have not turned eighteen yet. Nevertheless it seems unlikely that this law was actually broken on Monday afternoon. Indeed, only ‘active’

students were invited personally, such as committee members of study associations.

In general these are slightly older students, which is clear at the meeting.

The committee members of the study associations GEWIS (W&I) and Lucid (ID) are aware of the new situation. Both Departments count a number of students under 18, as the members present explain. The odd minor also showing up at a drink is easily recognizable for the bar tenders. “At bigger events we will perhaps start working with armbands”, says a Lucid committee member, “for we may be fined considerable penalties, and of course our budget does not allow for those.”

A small sample shows that alcoholic drinks are significantly more popular among students than non-alcoholic alternatives: three times more alcohol is drunk than soft drinks and juice, with wine and beer seeming to be equally popular. Altogether the estimated turnout of 425 persons drank some 100 liters of beer, 34 bottles of Prosecco, 25 bottles of white wine, 14 bottles of red wine, 10 liters of mineral water and 60 liters of orange juice.

The weight of light Interviews | Tom Jeltes Photos | Bart van Overbeeke COBRA is doing great. They’ve landed a twenty-million-euro Gravitation Grant, thanks to which the future of the research school is safeguarded for the next ten years. That time span will allow the club of Eindhoven electrical engineers and physicists to take on the issue of our ever-growing, energy-sucking digital data traffic - with photonics, the technology of light.

The Gravitation Grant is meant for consortiums of the very best research groups in a specific area of expertise - it’s only the best three percent that’s eligible for the grant.

The grant proves that COBRA has built an impressive reputation over the past two decades. And the people involved feel that way, too.

“Internationally, we hold an authoritative position in our field”, says main applicant prof.dr.ir.

Meint Smit. “In the world of optical communication technology, everyone knows COBRA.” His colleague and scientific director of COBRA prof.dr. Harm Dorren concurs: “We’ve become a brand”.

“COBRA has become a brand” The status of COBRA is also corroborated by an independent body. Several years ago, an evaluation committee stated that COBRA doesn’t face any competition from other academic research groups in Europe. It’s only commercial laboratories and “one or two US universities” that are a match for COBRA. In 1998, COBRA was acknowledged as one of six national Top Research Schools and has since operated in large part on funding from the Depth Strategy support program

by NWO, as National Research Center Photonics. That program ended last January 1, says Dorren.

“This Gravitation program, the Research Center for Integrated Nanophotonics, is really the successor of NRC Photonics.”

The most important difference is the incorporation of Physics of Nanostructures (FNA) of prof.dr.

Bert Koopmans, and Plasma and Materials Processing (P&MP) of prof.dr.ir. Erwin Kessels. Both professors are from the Department of Applied Physics. “Now the share of Electrical Engineering and Applied Physics within COBRA is more well-balanced”, says Smit.

“And our scope has widened, too.”

FNA and P&MP bring expertise to the COBRA table in the areas of spintronics and atomic layer deposition. Originally, COBRA

knows a vertical structure. Of the three initial core groups, Photonics and Semiconductor Nanophysics (supervised by prof.dr. Paul Koenraad, who’s also the director of education at COBRA) develops new materials, which are subsequently processed into optic components by the group headed

by Meint Smit (Photonic Integration, PhI). The third core group, ElectroOptical Communications (ECO, run by prof.ir. Ton Koonen and Harm Dorren), researches how those components might fit into full systems like data centers and networks that are the final link to the end user. “We continue each other’s work almost organically”, as Dorren puts it. And that’s exactly what the parties involved consider the basis for the success of COBRA.

Low-temperature optical probe station (PSN)

A solution to a serious problem With the Gravitation Grant, the TU/e researchers want to find a solution to a serious problem that’s quickly surfacing. According to Moore’s Law, the capacity of our computers grows by a factor of approximately one hundred every ten years.

However, data traffic increases thousandfold in the same time.

To prevent everything from crashing, the infrastructure is currently being expanded like mad: mega data centers spring up everywhere. Still, that process has to end at some point, if only for the fast-growing electricity consumption of those behemoths. Smit: “In the United States, data centers are already responsible for two percent of the total energy consumption.

Taking the current technology into account, that percentage will rise to more than twenty within the next ten years. And that means trouble.”

Closer to home, inside even, limitations are tangible, says Ton Koonen. The last meters to the end user, through fiber-to-the-home and wireless networks, that’s where telecom networks consume most of their energy, he says. “And here, too, optical techniques can reach a higher capacity and save energy.”

If the current trend continues, either consumers will be paying much more for their digital services

within the foreseeable future, or they’ll have to settle for last-century (download) speeds. Unless there’s a way to market a faster and more energy-efficient technology.

And optical communication through light signals instead of electrical currents is just that. So the strategy researchers have come up with is to make all data communication between and within computers optical, down to the PCBs and chips. Eventually, only the processors will be electronic, and the

entire data stream will consist of light.

That development is already in full swing: today, long-distance data transport is already done by means of optical fiber exclusively. In the next decade, COBRA wants to make important contributions to the integration of photonics in computers, data centers, and the last meters to the end user.

And it’s not just NWO that has contributed to the new Research Center for Integrated Nanophotonics; TU/e will be paying for the operating

costs of the cleanroom (NanoLab@ TU/e). The university has also granted COBRA the appointment of four female researchers from the WISE tenure program. Smit: “That will bring our percentage of female staff members to 25, which is quite an impressive score in our line of work”.

Scanning near-field optical microscopy on lensed fibers (PSN)

Spintronics in the STM lab (FNA)

COBRA: Research Center for Integrated Nanophotonics Goal of the new COBRA program is to improve the energy-efficiency and speed of digital systems by making as much of the data transport as possible optical (as light, with the use of new photonic technology). In line with the vertical setup of COBRA, the new technology is implemented at several levels, ranging from the manipulation of a few light particles to complete optical networks. A short overview of future plans.

have to find ways to force the light into a much tinier space than it actually wants to be in. Doing so requires new semiconducting materials, and structures with numerous thin layers of isolators and metals.” The latter issue will hopefully be resolved by the expertise of that other newcomer, Erwin Kessels. And then there’s Kessels’ colleague dr. Ageeth Bol, whose work on graphene may offer interesting possibilities for optical technology.

One of the important challenges is the development of optical memories in which the data stream can be stored temporarily. Right now, there isn’t a good method to store information as light yet, says Paul Koenraad. “But it’s an interesting challenge to try to do so with spintronics (through the interaction between light and the magnetic properties of atoms, ed.), which is why Bert Koopmans’ group is involved in this project.”

“Working on the verge of what’s possible”

We also have to bear in mind that the optical components have to be fitted onto ever-smaller electronics.

That’s not easy either, Koenraad explains: “Electronic transistors only measure a few dozen nanometers, which is much smaller than the wavelength of light. We therefore

The ultimate step towards minia­ turization is using only a few light particles (photons) to work with.

After all, less light generally means a more economical system. Prof.dr.

Andrea Fiore of PSN has been working on such systems. It’s unsure whether or not they will ever be implemented on a large scale, because they have to be cooled to a few degrees above absolute zero. Meint Smit doesn’t see a problem there, though: “Truly, Andrea is working on the verge of what’s possible, but he may well learn things we can use

in other aspects of the program.”

On the other end of the spectrum we find the input of ECO, where Harm Dorren works on optical networks and optical switches in data centers (see also the article on doctoral candidate Stefano Di Lucente in Cursor 8). Within that same group, Ton Koonen is responsible for the final meters to the consumer. Those can be made optical too, wireless even, with the use of infrared light.

The level in between - the chips - is program leader Meint Smit’s area.

“In the time of NRC Photonics we’ve learnt how to integrate large numbers of optic components on a single chip”, he says. Among other things, it’s led to an optic switch matrix including over 450 components, which has been developed in the group of prof.dr. Kevin Williams.

“It’s one of the most complex chips that’s ever been created”, according to Smit. “Now we want to merge optical and electronic switches on one chip. We hope to realize that by developing a layer with an entirely optical network that goes on top of the electronic chip.” Every second, that layer will transfer hundreds of billions of bits to and from the processors (cores) on that chip.

Part of this process is the development of small, fast, and energyefficient light sources on chips:

nanolasers, of which each chip will need thousands. That challenge will be tackled with the help of the group of Andrea Fiore.

1 | cover The front cover shows a side-view scanning electron microscope (SEM) image of nanoscale semiconductor material: Indium Phosphide (InP) nanowire arrays grown on an InP substrate using MOVPE (a chemical vapor deposition method, ed.). Using catalyst engineering, we can tilt the growth direction of a crystal from vertical <100> to <111>, creating palm tree-like nanostructures. The back cover image is a transmission electron microscope (TEM) picture of a zigzag InP nanowire, which changes its growth direction twice during the growth process: from <100> into <111> and then back into <100> again.

2 | parties New materials are the base for new devices with new functionality or improved performance. My work enables people to explore new functional nanoscale devices, such as high-efficiency nanowire solar cells, nanowire LEDs, nanowire biosensors, and new nanostructures such as nanocrosses. Iâ&#x20AC;&#x2122;ve also spent a lot of time working on the modeling of the growth direction of nanowire, which could be considered boring. Using the model, however, enabled me to which growth direction is preferred. Finally, those boring modeling results turned out to be consistent with the more interesting experimental results, making the whole endeavor quite interesting entirely.

Photon detectors for secure information transfer 1 | cover My research project concerns photon detectors operating at either single-photon or at fewphoton level. The cover picture shows a pulse-height distribution of an integrated photonnumber-resolving detector (PNRD) and each pulse corresponds to the detection of zero, one, two, three, or four photons, respectively. A PNRD resolves how many photons in an optical pulse impinge on it. It’s crucial in quantum communications to detect eavesdropping, for example and it’s therefore crucial in quantum communication, for example to resolve the presence of eavesdropping.

2 | parties As confidentiality affects people in their daily lives, I usually make an analogy to online banking as an application. For the password transfers, classical channels are used. If someone eavesdrops on those channels and steals your password, they’re free to empty your account! Classical channels are prone to interception. However, if the channel is secured by password encryption based on quantum mechanical rules using single photons (this is called quantum key distribution, or QKD) then the password is transferred safely. For this purpose, single-photon or photon-number-resolving detectors are required to detect the photons.

3 | essential The detectors are based on superconducting material that I’ve developed in the NanoLab@ TU/e cleanroom facility. They operate in cryogenic setups (temperature ≤ 5K). Furthermore, these detectors are integrated using waveguides to establish a link between hundreds of detectors and single-photon sources. Thus, the cryogenic setup requires suitable optics.

4 | society benefit If anything, this research project will solve the problem of insecure information transfer.

Predicting knee pain

1 | cover Since my study focused on Osteoarthritis (OA), a very common disease in the knee, I’ve picked a photo of a painful knee. And because OA affects knee cartilage, you see two images of cartilage tissue, healthy above and diseased below. On the very bottom of the cover design, you see the arcade-like orientation of collagen fibers, which has a very important role in the mechanical functionality of the cartilage. Beside all these images, there are a number of squared mesh blocks symbolizing the Finite Element Method (FEM), the numerical approach I’ve used to investigate OA cartilage in my thesis.

2 | parties Many senior citizens suffer from knee pains, which may be a sign of OA. In order to avoid it, we need a predictive tool telling us about the current and future status of the knee. For my research project, we developed such a predictive tool for cartilage, which tells us about the initiation and progression of cartilage damage.

3 | essential My supervisor (dr. René van Donkelaar) and my promoter (prof.dr. Keita Ito) have been indispensable for my project.

4 | society benefit In the near future, my work may provide physicians with a computational predictive tool, which can help them in the prognosis and diagnosis of OA.
