Despite her rigorous course load and all of the other challenges of being a freshman, Stephanie landed on the dean’s list for both semesters of her first year at Georgia Tech. Her ChBE professors say that she is an “impressive student.”

In high school, Stephanie was a threeyear letterwinner in diving and was team captain her junior and senior seasons. She qualified for the America Cup and participated in the platform diving event at the U.S. Junior Nationals. Additionally, she won district championships in three consecutive seasons. In the meantime, she also excelled in the classroom, ranking third in her graduating class. She was a member of the National Honor Society, the Chemistry Honor Society, the German Honor Society, and Mu Alpha Theta. Parents Gordon England and Susan Eggers are naturally extremely proud of their multitalented daughter. During what little free time she enjoys these days, Stephanie likes to rollerblade and go to the beach. Keep up the good work, Stephanie!

At this year’s AIChE Southern Regional Conference in New Orleans, four undergraduate students from Georgia Tech made presentations on research they conducted as members of faculty research groups: Veda Bartlow (Prof. Nair), Joshua Hutcheson (Prof. Prausnitz), David Meyer (Prof. Eckert), and Holly Paskow (Prof. Rousseau). A panel of three chemical engineers judged the papers based on technical content and research quality, as well as on the student’s presentation of the paper and his or her ability to respond to questions about the material. All four Georgia Tech students did an excellent job presenting their work, and Veda Bartlow won the first prize in her group as well as second place overall. She received a cash prize of $1,250 and was later recognized at the 2005 ChBE Student Honors Luncheon.

Focus on the School Message from the Chair By Ronald W. Rousseau School Chair

The School faculty, staff, and students have had a busy and eventful academic year 2004-2005. In thinking about this communication, I am reflecting on what seems to have been an extraordinarily busy time. I want to tell you first of many of the highlights of the year: • Counting those expected to graduate at the end of the coming summer semester, we will award about 93 BS, 20 MS, and 25 PhD degrees. We anticipate the number of BS degrees to increase gradually over the next few years as our undergraduate enrollments are increasing. The number of PhDs will be the highest we have awarded, and this number is likely to be more typical of our future. • The undergraduate student advisory board has matured into a thoughtful, constructive group that has played a positive role in improving many aspects of student-faculty relations. • Employment of our undergraduates is strong and reported salary offers again place our graduates at the top of the salary scale. • Research output, as measured by research publications and patents applied for or granted, was superb, and signs indicate continued growth. • A number of our faculty received national or international awards in the past year, recognizing them for their unique strengths, including: Charles Eckert & Charles Liotta: Presidential Green Chemistry Challenge Award, given jointly by the U.S. Environmental Protection Agency and ACS Martha Gallivan: NSF CAREER Award Dennis Hess: Award in Solid State Science and Technology, given by the Electrochemical Society

• Two new faculty members, Rachel Chen and Hang Lu (see related story page 8), joined our faculty and brought additional strength in biologically related programs to the School. They also provided our female students two more outstanding role models.

In the last newsletter, Dr. Sue Ann Bidstrup Allen was introduced as the new Associate Chair for Student Initiatives. Her work on several new programs has been outstanding. Therefore, it is with mixed feelings that I inform you that she has accepted President Clough’s offer to be the Executive Assistant to the President. We know she will do well with her new responsibilities, and we are happy for and proud of her for being selected (see related story page 8).

• Levi Thompson will join us in the fall as the Hercules, Inc./ Thomas L. Gossage Chair. He will add to our research capabilities in catalysis and fuel cells and will bring significant leadership experience to his new position. • Alumni were cited for their contributions at the COE Awards Ceremony (see photo page 11):

Many in the field of chemical engineering have been wondering about the health of our discipline. Some have worried that the changes in the names of academic units long known simply as Chemical Engineering to Chemical & Biomolecular (or Biological) Engineering reflected a departure from

long-established traditions. It may not be possible to allay such concerns in the space available here, but I would like to state unequivocally that we do not believe that to be the case. Moreover, I think the new name merely indicates that we chemical engineers are saying to the rest of the world that we intend to add some tools and applications to our portfolio. We will be even stronger in our use of molecular sciences because we’ve added biology to the blend. We will include new applications of our systems outlook; as we have done with non-biological chemicals, we will design, develop, and use processes that rely on living organisms to generate, modify, or otherwise influence products. We will continue to view our milieu as extending from angstrom-length entities to huge ecosystems. And most importantly, we will continue to address problems of great importance, including those dealing with energy, environment, food, health, poverty, and quality of life, using problemsolving skills developed in the study of our discipline.

A team of ChBE students was recently awarded first prize in the undergraduate student paper competition sponsored by the Georgia Chapter of the Product Development Management Association (PDMA). In their winning paper, the team of Robert Casey, ’05, George Parker, ’04, Nisha Shah, ’04, and Robyn Smith, ’04, described a new product that they developed in ChBE 4803: Chemical Product Design, Engineering, and Optimization.

Michael Lazzaroni received the Separations Division Graduate Student Research Award in Extraction from AIChE for 2004. The award recognizes outstanding graduate students in any of the Separations Division’s research areas. Prof. Charles Eckert is Michael’s advisor.

For the class project, they chose lip balm as a benchmark product they wanted to improve. They applied a general product design algorithm that they learned in class to develop an improved product. Utilizing a “Stage/Gate Process” akin to those used in industry, the team carried out the design process in stages. Their final design consisted of a replacement cap for lip balm tubes that contains a dispenser for breath strips and is compatible with any tube of lip balm. The team describes it as “a complete mouth care product” that is small, lightweight, and eliminates the need to carry both products separately.

The 17th annual Graduate Student Symposium was a great success From left: Charles Eckert and under the leadership of Chairs Michael Lazzaroni at AIChE’s Elizabeth Giambra and James Separations Division Dinner. Falabella and Vice Chairs Christopher Gill and Justin Johnson. The student-run event, which was held March 31-April 1, provides a forum for graduate students to interact with industry representatives. Graduate students presented research from their projects through both oral presentations and posters, and the industry representatives selected the winners in both categories. This year, the winners for the Oral Presentations were: 1st Place – Anshul Dubey, 2nd Place – James Russum, and 3rd Place – James Broering. For the Poster Presentations, the winners were: 1st Place – Laura Draucker, 2nd Place – Kim Nelson, and 3rd Place (tie) – Anna Fallon and Paul Jason Williams.

In addition to being recognized by the PDMA at a banquet on April 28, the team received a cash prize of $1,000. This is the second year in a row that a team from ChBE’s Chemical Product Design class has taken home the top prize. This elective class is a new offering in the School that was first taught in 2003 by Prof. Christopher Jones. In 2004, Profs. Carson Meredith and Matthew Realff became involved, and the three professors greatly expanded the scope of the course with the support of a curriculum development grant from the Procter & Gamble Fund. The course has received rave reviews from students who have taken it and will continue to be offered every fall semester.

Six undergraduate students have been awarded merit scholarships to participate in the School’s Summer London Program. The scholarships were made possible through the generosity of Monsanto and Chevron Texaco. Recipients of the scholarships are Stephen Baehl, Stephen Fisher, Megan Lane, Craig Simpson, Rebecca Ugalde, and Lisa Wills.

Eighteen students participated in last year’s London Program. They are shown here with Prof. Cliff Henderson in front of the Chepstow Castle in Wales.

ChBE students have been participating in the program for more than 25 years. During the five-week-long course, students from Georgia Tech along with students from other ChE departments in the U.S. study unit operations at the Department of Chemical Engineering at University College London. In addition to the technical component of the program, students attend lectures on the history, culture, and sociology of Great Britain and visit chemical facilities, Roman ruins, and Norman castles. A total of 15 chemical engineering students from Georgia Tech will participate this summer from June 19-July 22 under the supervision of Associate School Chair F. Joseph Schork.

This spring, Shell Oil Company sponsored a design competition as part of ChBE 4505: Process Design and Economics. Rich Higgins, a representative from Shell, judged the finalists and selected the following students for the top prizes: first place: Sahil Kochhar, Rob Casey, Robert Eads, and Griffin Fulmer; second place: David Bryson, Haley Hudson, Craig Rowe, and Brandon Friloux; and third place: Sean Holton, Nina Paolella, and Clay Plavcan. Congratulations to all of these students for their outstanding analysis of a complex, real-life industry problem.

One undergraduate student (who is a Georgia resident) from each of the 34 institutions in the University System of Georgia is recognized for academic excellence through resolutions passed by the House and Senate. Justin received certificates from both the House and Senate.

Prof. Chris Jones’ Ph.D. student John Richardson, a former NSF fellow, was awarded an NSF IGERT fellowship to participate in the crossuniversity, multidisciplinary program between Emory and GT from 20052007. John was chosen based on a competitive review process, including a written application followed by interviews with the program organizers. About 21 individuals applied and John was one of only five that were accepted. John also was the recipient of the 2004 AIChE Student Chapter Outstanding Teaching Assistant Award.

In addition to making important contributions to Prof. William Koros’ research group and achieving academic excellence, graduate student Hensley Sejour has another talent that he likes to hone in his spare time: he’s the Georgia Tech Men’s Ultimate (Frisbee) defensive captain and specialist. As a crucial part of his team, Hensley calls starting lines for defense as well as helping with overall team management. He received his Hensley Sejour (right) in the middle of B.S. degree from Lafayette one of his famous dives for the frisbee College in Spring 2001, where he during a game of Ultimate. ran track as an undergraduate Chemical Engineering major. Using his quick acceleration and overall speed, Hensley amazes onlookers with his layout defensive style and hard cuts on the offensive side of the disc. After watching him play, it’s surprising to find out he only began playing Ultimate three years ago. Now, he also plays on Atlanta’s Chain Lightning, a club team that consistently participates in Ultimate Club Nationals, the highest play level the sport has to offer. Under the leadership of Hensley, GT Men’s Ultimate hopes to have one of its most successful seasons ever.

For the second year in a row, a graduate student in both ChBE and the College of Management has placed in the top three in the Georgia Tech Business Plan Competition organized by the College of Management. Last year, Chris Power, ChE ‘03, MGMT ‘03, received the honor; this year the prize goes to Prof. Dennis Hess’ student Sudeep Vaswani. Sudeep graduated in May with a Ph.D. in Chemical Engineering and received an MBA in December 2004 from the College of Management. He and his wife, Akanksha Nagpal, a Ph.D. student in the School of Chemistry and Biochemistry, co-founded a company named ProFold. ProFold took first place for being the most fundable venture team, winning $32,500 in services. ProFold also took third place in writing, presenting, and defending the business plan category, winning a $2,500 cash prize. Additionally, they won the $500 first prize in the “Elevator Pitch” competition for presenting the best 60-second pitch. ProFold is a very early-stage venture with a key idea to design molecules and surfaces for correctly folding protein molecules, thereby improving the yield of protein-based drugs in the biopharmaceutical industry. Their offering would enable protein drug manufacturers to increase their drug yield, reduce waste of expensive proteins, and reduce the time to market. 4

Nanotechnology Focus on Research William J. Koros

J. Carson Meredith

Sankar Nair

Amyn S.Teja

Professor Koros works at the interface of membrane engineering and nanotechnology, developing advanced membranes to achieve more energyefficient separation of gas mixtures. Membranes selectively pass one of the components in a feed stream while keeping other components from passing across the membrane. The Koros group produces polymeric and carbon-based materials, as well as hybrid nanomaterials composed of polymers containing nanoscopic molecular sieve domains. The separation properties of ultra-thin (100 nanometer) selective layers of these materials, supported on porous fiber cores, are carefully engineered by adjusting the composition of these layers, creating many new opportunities for performing difficult separations. Large-scale membrane modules are then created by an integrated strategy spanning the nanoscale through to the macro-scale. Applications of the technology include purification of natural gas and production of nitrogen-enriched air for inert blanketing of fuel tanks or for pesticide-free storage of foods.

Professor Nair’s work focuses on developing new nanometerscale materials with novel properties, and then creating processing strategies to assemble them into functioning devices and systems. These capabilities are vital in the emerging field of nanotechnology, wherein functional devices can be created by precise chemical and physical manipulation of molecular “building blocks.” These devices will ultimately overcome the intrinsic limits of the currently available device fabrication and manufacturing technologies. For example, Dr. Nair’s group is currently synthesizing nanotubes and other similar “nanocomponents,” which are then assembled into arrays in which the operation of each component can be controlled separately. These arrays are being interfaced with existing integrated circuit technology to create new sensors that can identify and classify biomolecules like DNA and proteins many times faster, and in much smaller quantities, than current technology. An important component in this multidisciplinary program is to quantitatively explain the function of these nanometer-scale materials in terms of their molecular structure through combined experimentation, simulation, and theory.

Professor Meredith’s research aims to discover fundamental “rules” for stabilizing nanoscale films and particles. The applications of nanotechnology in electronics, biomedicine, and sensors depend on controlling the stability of nanoscale thin films and particles. Molecular electronics is an emerging field in which thin organic films are used as semiconductors. Benefits of this technology are mechanical flexibility, lower costs, and versatility in electronic sensors and communications. Achieving stable semiconducting organic nanoscale films is a significant problem. Dr. Meredith’s students recently discovered a method for creating stable semiconducting interfaces down to a thickness of 20 nm, and an unexpected instability between 100 and 200 nm. These discoveries define important boundary conditions and illuminate problems to solve in patterning nanoscale organic semiconductors. The design of nanomanufacturing processes is also limited by a lack of reliable models for designing stabilized nanoparticles. Using an innovative molecular simulation model, Dr. Meredith’s group has presented the first calculations of nanoparticle chemical potentials, e.g., the energy required to disperse particles, and has validated them by comparison to experiments using novel techniques developed in their lab.

Professor Teja’s research focuses on developing near-critical and supercritical processes for synthesizing nanoparticles and nanocomposites, which can then be used for a wide range of technological applications. Solvents near their critical points offer many advantages in nanoparticle syntheses because of the tunability of their properties by very small changes in pressure and temperature. In addition, continuous processing using near-critical solvents offers ease of scale-up for nanoparticle manufacture, as well as better control of the factors that affect size, size distribution, and morphology of nanoparticles. Specific nanomaterials that are being synthesized via continuous near-critical processes include magnetic oxides for information storage applications, lithium iron phosphate as a cathode material for lithium-ion batteries, and metal oxide-carbon nanocomposites for catalytic applications. The transport properties of nanofluids (fluids containing dispersed nanoparticles) are also being studied to identify new high-performance heat transfer fluids for both large-scale cooling as well as for heat transfer in microfluidic devices.

The background image depicts a nanotube – a tubular material about a billionth of a meter across – which is one type of “building block” that nanotechnologists and nanoscientists are using to fabricate devices with entirely new capabilities.

Focus on Faculty Faculty News Charles Eckert was the organizer and chair of the Minisymposium on Tunable Solvents for Sustainable Technology at Georgia Tech. The event brought together an international group of leading chemists and chemical engineers in tunable solvents. The meeting was so successful that the group decided to make it an annual event. Dr. Eckert also gave ten invited lectures and presented 17 others.

Pete Ludovice presented a comedy routine at the Spring 2005 AIChE National Meeting and the Carpet America Recycling Effort National Meeting.

He also presented lectures at the Jet Propulsion Laboratory in Pasadena, the American Geophysical Union Fall Meeting in San Francisco, the Department of Earth and Atmospheric Sciences at Harvard, and the CDSNS Colloquium in the School of Mathematics at Georgia Tech. Additionally, research coauthored by Dr. Nenes was recently published in the Journal of Geophysical Research and has received a lot of media attention. The research focuses on the potential impact of air pollution on iron fertilization of the oceans, which if true, indicates that pollution can increase the amount of CO2 sequestered by the oceans, thus potentially having an impact on global warming.

Larry Forney presented an invited lecture entitled “UV Disinfection in Taylor-Couette Flow” to DuPont’s Clean and Disinfect Group. James Frederick was an invited speaker at the S.C. Governor’s Forestry Summit and spoke immediately after the governor on the topic “Assessing The Pulp and Paper Industry Outlook.” In October, he visited five countries in Southeast Asia to promote membership in the IPST Center at Georgia Tech and presented seminars at the Taiwan Forestry Research Institute in Taipei and at the Asian Institute of Technology in Bangkok. While overseas, he visited the world’s largest pulp mill, which is on the island of Sumatra in Indonesia.

Mark Prausnitz has been awarded the 2005 Controlled Release Society Young Investigator Award for his outstanding contributions in the science of controlled release. It is an international award from the leading drug delivery society to individuals under the age of 40. He was also appointed to the Advisory Board of the Center for Drug Delivery Research at the Southern School of Pharmacy at Mercer University. Additionally, Dr. Prausnitz gave invited lectures at Sandia National Laboratories, Rensselaer Polytechnic Institute, Emory University, and Brooklyn Polytechnic University.

Dennis Hess served as a moderator at the Chemical Heritage Foundation “Moore’s Law at 40: Chemistry and the Electronics Revolution” symposium in Philadelphia in May. The event was co-sponsored by The Electrochemical Society and assessed both the impact of Moore’s law and the enabling role of chemical science and engineering in the development of the semiconductor industry. Jeffery Hsieh presented “From Industry to Academia” as a keynote speech to the Chinese-American Chemical Society during the AIChE 2005 Spring National Meeting in Atlanta.

Ronald Rousseau gave the presentation, “Processing Solids: The Forgotten Phase,” in an invited keynote address at the VI Chemical Engineering International Congress in Monterrey, Mexico. The Congress was organized by the Chemical Engineering Student Association at the Instituto Tecnológico y de Estudios Superiores de Monterrey (ITESM), a prestigious Mexican University. He also was a Warren L. McCabe Lecturer at North Carolina State University where he presented the seminar “Crystallization from Solution and the Phenomena that Determine Crystal Form, Purity and Morphology.”

Chris Jones has been honored with three prestigious awards. He received the Sigma Xi Young Faculty Award for 2004, which recognizes the originality of his scientific contributions and potential impact of research described in his series of papers on the molecular design of novel polymerization catalysts. The second award was a “Young Scientists Prize” from the International Association of Catalysis Societies for his work on silica-immobilized polymerization catalysts. Lastly, he was awarded a DuPont Young Professor Award, one of only about 12 presented annually.

Amyn Teja was recognized at the Faculty/Staff Honors Luncheon for his 25 years of dedicated service as a ChBE faculty member. (See page 6 for details about his current research activities in nanotechnology.)

William Koros was an invited lecturer at the first U.S./India Joint Meeting between AIChE and the Indian Institute of Chemical Engineering. He also presented at the National Research Council in Washington, D.C., and was the sixth annual Patten Distinguished Lecturer in the Department of Chemical and Biological Engineering at the University of Colorado at Boulder.

Agit Yoganathan has been awarded the 2005 Theo C. Pilkington Outstanding Educator Award from the American Society for Engineering Education (ASEE) Bioengineering Division (BED).

In recognition of the outstanding career achievements of Georgia Tech Chemical Engineering graduate C.J. “Pete” Silas,The Phillips Petroleum Foundation awarded a grant to the School of Chemical & Biomolecular Engineering to develop the Phillips Petroleum/C.J. “Pete” Silas Program in Ethics and Leadership. Ethics, leadership, and quality, founded on the basics of strong communication skills and professionalism, are regarded as essential components of an engineering education. This program spotlights the importance of ethics and leadership by focusing on technical and business decisions that have ethical ramifications. These topics and related areas are integrated into the required chemical engineering courses and are addressed in an annual public symposium with prominent industrialists and ethicists leading discussions on current issues of technology and ethics.

ChBE Dedicates Portrait of Founder & Names First Emerson-Lewis Faculty Fellow In a special ceremony on April 21, the School unveiled a portrait of William Henry “Big Doc” Emerson (1860-1924), the legendary educator who founded the chemical engineering program in 1901. He literally opened the door on the first day of classes at Georgia Tech, and also served as Dean of Engineering. School Chair Ronald Rousseau told the gathered faculty, staff, and students that displaying Dr. Emerson’s portrait in the main ChBE office was the perfect way to recognize the founder of the School. The portrait is a reproduction of an original 1920s oil painting by local artist Kate Edwards that hangs in a campus administration building.

Cherry L. Emerson & Mary Lewis Emerson are longtime supporters of the School. They are shown here with the first Emerson-Lewis Faculty Fellow, Mark Prausnitz.

Cherry L. Emerson (William’s grandson) and his wife Mary Lewis Emerson attended the event, which also celebrated the introduction of the first Emerson-Lewis Faculty Fellow in ChBE, Prof. Mark Prausnitz. A generous and unrestricted 9

gift from the couple to ChBE was used to establish the faculty award program this year. The award’s name recognizes the importance of both families in chemical engineering: Cherry built a successful career in chemical engineering after studying at M.I.T. with Mary’s father Dr. Warren K. Lewis; and Mary’s brother, Dr. H. Clay Lewis, taught chemical engineering at Georgia Tech for more than 30 years. The Emerson-Lewis Faculty Fellow will be awarded annually for four years to recognize an outstanding faculty member who shows great promise early in his or her career. The fellowship will be $25,000 for the faculty member’s use in teaching and research activities. The School extends sincere appreciation to Mr. and Mrs. Emerson for their continued support of the School and their commitment to chemical engineering education.

Alumni Spotlight: J. D. Fleming, Jr., ChE, B.S.‘55, Ph.D.‘59

By Jenny Daley Director of Development

One very accomplished ChE alumnus calls J. D. Fleming “the brightest mind to go through Chemical Engineering at Georgia Tech.” But maybe Julian Denver Fleming, Jr.’s career practicing law was determined from the moment he was first called “J. D.” Chemical Engineering occupied important early steps along his path to being named one of “The Best Lawyers in America 2005-2006” based on a peer-review survey of 16,000 of the leading attorneys in the country. Dr. Fleming was born in Rome, Georgia, and later his fascination with high school chemistry took him out of the state to study during his first two years of college. When tuition monies ran low, he transferred to Georgia Tech and into Chemical Engineering – a move he says he has never regretted. “Georgia Tech was a place where hard work was expected. I liked that atmosphere,” Dr. Fleming says. He also recalls lighter times like the student prank of dynamiting the guard house on campus; no-one was ever hurt, but it was amusing to the students. He completed his BSChE with highest honors and decided to keep studying toward his Ph.D. At GT’s Engineering Experiment Station (the precursor to GTRI), he worked as a Research Engineer with high-temperature materials like fused silica, which is used for nosecones for missiles and rocket nozzles. He was also a Staff Consultant with the Oak Ridge National Laboratory. Dr. Fleming earned his Ph.D. and taught ChE for twelve years at Georgia Tech, rising to the rank of Professor. He remembers enjoying how the professors worked as a group. He cites an informality in the program then, with the 15 graduate students calling younger faculty members by their first names. He says that teaching was “unregimented” in that there was room for imaginative approaches to the discipline. While teaching and conducting research, Dr. Fleming supplemented his income by consulting for attorneys. His late wife, a psychiatrist, was then in her residency and working unusual hours. Dr. Fleming decided the time was right for additional education, although he did not plan to

pursue a degree. He began taking night classes at Emory Law School to learn the legal jargon he encountered in consulting – and discovered he enjoyed the coursework. As he neared the completion of the required classes for a Juris Doctor, classmates began asking him with which firms he planned to interview. It was then that he finally seriously considered starting a career as a lawyer. His stellar intellect and high marks J. D. Fleming, Jr. at Emory landed him a position with the respected firm Sutherland, Asbill, & Brennan. There was some skepticism in the legal field then of how a technical background would help an attorney. However, Dr. Fleming became invaluable to the firm, and over 30 years has built a practice in increasingly complex technology and intellectual property matters while developing well-recognized skills that address tax law issues and litigation for businesses. He practices primarily in the areas of civil and tax litigation and has substantial trial experience in controversies involving science and technology, including product liability, patent infringement, trade secrets, intellectual property, environmental matters, industrial technology, occupational health and safety, and federal taxation. Dr. Fleming believes that Chemical Engineering is still a valuable course of study, even for someone considering becoming an attorney. “You will do best going into law with broad knowledge, as someone who dabbles in many interests,” he says. Clearly, J. D. Fleming did more than dabble in Chemical Engineering. He has passed on his intellectual curiosity and devotion to education to his daughter, Julie, who is also an attorney and has studied biology. Dr. Fleming’s former students and legal clients are among those grateful for his trail-blazing career path.

The final component of the Biotechnology Complex – the Molecular Science and Engineering Building – officially broke ground during an April 15 ceremony. It joins the ES&T, BME and IBB buildings where ChBE faculty members have offices and laboratories. The School expects to have a presence in the building as nanotechnology, a major initiative in which ChBE professors are actively involved, is the primary research activity planned for its laboratories. The Molecular Science and Engineering Building will complete the Biotechnology Complex. This rendering shows the “M” Building’s location in relation to the Ford ES&T Building, home of ChBE.
