Prof. Woo's Team Discovers Eco-Friendly Solid-Oxide Fuel Cell System
A KAIST research team led by Prof. Seong-Ihl Woo of the Department of Chemical & Biomolecular Engineering has found a method to use glycerol, a byproduct from the production of biodiesel, as fuel for solid oxide fuel cells (SOFC), university authorities said on Tuesday (Oct. 27).
The research finding shows that glycerol can be an environmentally sustainable fuel when it is used for operating SOFCs with internal reforming, instead of hydrogen and methane. The finding was published in the Oct. 14, 2009 online edition of ChemSusChem, a sister journal of Angewandte Chemie, the world"s leading chemistry journal.
Biodiesel is an attractive alternative energy source because of its low sulfur content and demand is growing worldwide as oil price soars. Bio-derived glycerol will not contribute to the greenhouse effect and has the potential to contribute to reducing global warming.
Currently, glycereol is used as a raw material in the cosmetic, pharmacy, food, and tobacco industries. However, its supply exceeds its demand as the volume of biodiesel production increases. The production of 1 ton of biodiesel produces 0.1 ton of glycerol. Many researchers have investigated various routes for the consumption of surplus glycerol.
The research is expected to contribute to sustainable growth by reducing the emissions of carbon dioxide and reusing generated carbon dioxide for the production of biomass. The new method enables manufacturers to use glycerol as a fuel for operating SOFC.

Board Chairman Chung Makes First Visit to Building Named After Him
Moon-Soul Chung, chairman of the KAIST board of trustees, visited the building built with his donation on Monday (Oct. 19) for the first time since he made the deed of gift eight years ago, university authorities said on Monday (Oct. 19).
In 2000, Chung, founder and former CEO of Mirae Corp, manufacturer of semiconductor testing equipment, announced retirement and handed over the presidency of his company to one of his managing directors. One year later in 2001, he donated 30 billion won, then equivalent to $30 million, to KAIST. It was by then the largest amount given by a single donor.
The major part of his donation went to constructing a building for the newly-established Department of Bio and Brain Engineering, and it was named after him. However, Chung did not attend the ground-breaking and dedication ceremonies, saying that he would not enter the building until KAIST achieved a breakthrough technology which can inject a hope to Koreans.
On his first visit to the building, he was briefed on the major research outcomes of the department over the past seven years, which were highlighted by the recent invention of an apparatus for measuring perfusion rate of legs. A KAIST team headed by Prof. Chul-Hee Choi invented a light leakage prevention unit including a light emitting device for radiating light having a certain wavelength onto a living body injected with Indocyanine Green (ICG).
According to Prof. Choi, the invention relates to an apparatus for measuring the perfusion rate of legs. The invention also includes a light leakage prevention housing formed to prevent transmission of external light.
Chung expressing satisfaction with the achievements and encouraged professors, researchers and students working at the Moon-Soul Chung Building.

World Research University Heads Discuss Challenges in Global Financial Turmoil at 2009 International Presidential Forum in Seoul
Leaders of the world"s major research universities discussed the impact of the global economic crisis on institutions of higher learning and their research activities in particular and exchanged opinions and visions on ways to increase cooperation with governments and industry at a symposium organized by KAIST Monday (Sept. 21) at the Westin Chosun Hotel in Seoul.
More than 50 participants of the 2nd International Presidential Forum on Global Research Universities represented institutions in North America, Europe, Southeast Asia, Australia, China and Japan. They were joined by 20 presidents of Korean universities and two dozens of leaders from industry and the government.
Under the main subject of "Challenges to Global Research Universities," the international symposium proceeded in four panel sessions. The subjects of each session and their keynote speakers were:
-- "Institutional Management in Times of Financial Crisis" by Kurt Kutzler, President of Berlin Institute of Technology
-- "Innovations in Education & Research" by Brian Cantor, Vice Chancellor of University of York
-- "Globalization of Institutes of Higher Learning" by Gary Schuster, Provost and Executive Vice President of Georgia Institute of Technology
-- "The Roles of Government, University and Industry in Green Technology Development" by KAIST President Nam-Pyo Suh
KAIST President Suh expressed deep gratitude to all participants for their presentations focused on how universities weathered the difficulties from the economic turmoil and how they were continuing efforts for innovation in research and education. He observed that the 2009 International Presidential Forum was again most successful and productive after the first in 2008 and offered a precious opportunity for leaders of research universities to establish effective networking among their institutions.
"The world has witnessed a global financial turmoil of unseen magnitude and many nations are still struggling under the devastating impacts. While universities were no exception in facing economic turmoil, they have realized renewed pressures and expectations from their respective communities to provide answers to the great challenges,” he said in his welcoming remarks.
"The conference I am sure will have a far-reaching influence on the course our research universities will take to shoulder greater responsibilities for building a better future of the mankind."
Some of the participants in the 2009 International Presidential Forum came to KAIST’s Daejeon campus to take part in the EEWS (energy, environment, water and sustainability) workshop which was held on Tuesday, Sept. 22.
The Chronicle of Higher Learning, the Washington-based newspaper specializing in university education, reported from Seoul that the Forum revealed that, while American universities struggle amid the harshest economic climate in a generation, institutions in much of the rest of the world are sheltered from the fallout by strong government backing.
“Delegates to a conference of university presidents (in Seoul on Monday, Sept. 22) heard that colleges in Asia and Europe are pushing ahead with expansion plans – even as their U.S. counterparts cut back.
“The 2009 International Presidential Forum… was marked by a sharp divide in the tone set by European, Asian, and U.S. college leaders. The Americans often sounded a deeply gloomy note,” The Chronicle reported. “Never before has the impact been this bad,” the paper quoted Vishwanath Prasad, vice president for research and economic development at the University of North Texas, as saying.
On the other hand, Yves Poilane, vice president of the Paris Institute of Technology, said, according to The Chronicle, “The largely state financing of most European universities has so far acted as a shelter, and higher education remains a priority for both European and French Universities.”
The Korea Herald, published in Seoul, said in its Sept. 23 editorial:
“This week in Seoul, a symposium of leaders from international and Korean research universities heard top scholars and administrators reveal how their schools have suffered through the year under reduced government subsidies and private endowments which forced them to postpone various globalization schemes and cut down on research expenditures. Applications for master"s and Ph.D. programs declined while large percentages of graduates failed to find jobs.
“With their country showing a rapid pace of recovery, universities in Korea are in a better situation than many of their overseas counterparts, especially considering the substantial government outlays for research and development in "low carbon, green growth" projects that are largely dependent on research universities. The more the government seeks their direct contributions, the harder universities should try to increase transparency and accountability in the use of taxpayer money, so as not to betray the nation"s trust in them.
“In the wake of the global economic crisis, academia, government and industry find themselves in closer ties as they share new concepts of innovation and development in a common quest for growth. The tripartite cooperation has new significance in the recovery process. To achieve any development objectives, the other two partners must prioritize the funding of universities.”

KAIST Opens "Bridge Program" for Prospective Freshmen from General High Schools
KAIST opened an academic study program to get the 150 prospective freshmen from general high schools ready for undergraduate course work at the tech university, university authorities said on Thursday (Sept. 3).
The "Bridge Program" is designed to offer online courses in mathematics, physics and chemistry to help students without sufficient knowledge in those subjects.
For the 2010 academic year, KAIST"s admission officers have chosen 150 prospective freshmen among a total of 651 students who had been recommended by their school principals. It is the first time that KAIST has alloted a certain number of freshman slots to applicants from general high schools.
The system was designed to prevent elite high school graduates from taking a disproportionately large share of admissions.
As a result, 91 high schools which never before had its student enter KAIST will have at least one enrolled in the university in the next academic year.
Among the selected 150 students, 132 applied for mathematics course, 125 for physics and 116 for chemistry.

Prof. Lee"s Team Pioneers Biotechnological Production of Chemical Using Renewable Materials
A research team led by Prof. Sang-Yup Lee of the Bio and Brain Engineering Department at KAIST has succeeded in engineering the bacterium E. coli to produce the industrial chemical putrescine, university authorities said on Monday (Aug. 31).
Putrescine, a four carbon chain diamine, is an important platform chemical with a wide range of applications for the pharmaceutical, agrochemical and chemical industries. It is currently used to synthesize nylon-4,6, a widely used engineering plastic.
The research result, published in the Biotechnology and Bioengineering journal, proviDrdes a renewable alternative to the traditional process using fossil fuels.
Currently the production of putrescine on an industrial scale relies on chemical synthesis, which requires non-renewable petrochemicals and expensive catalyst systems. This process is highly toxic and flammable with potentially severe repercussions for both the environment and human health.
"For the first time we have developed a metabolically engineered E. coli strain that efficiently produces putrescine," said Professor Lee. "The development of a bio-refinery for chemicals and materials is very important in a world where dependency on fossil fuels is an increasing concern."
The team developed a strain of E.coli capable of producing putrescine through metabolic engineering. This is where a cell"s metabolic and regulatory networks are enhanced in order to increase production of a needed material.
First the team weakened or deleted competing metabolic pathways within the E. coli strain before deleting pathways which cause putrescine degradation. They also amplified the crucial enzyme Spec C, which converts the chemical ornithine into putrescine. Finally the putrescine exporter, which allows excretion of intracellularly made putrescine, was engineered while a global regulator was engineered to further increase the concentration of putrescine. The final result of this process was an engineered E.coli strain which produced 24.2 g of putrescine per litre.
However, as it was believed that putrescine is toxic to microorganisms the team had to study putrescine tolerance in E.coli before it could be engineered to overproduce the chemical to the levels needed for industrial production.
The results revealed that E. coli can tolerate at least 0.5 M of putrescine, which is tenfold higher than the usual concentration in the cell. This level of tolerance was an important surprise as it means that E. coli can be engineered to overproduce putrescine to industrially competitive levels.
"The previously expected toxicity of putrescine may explain why its microbial production has been overlooked," said Lee. "Now a metabolically engineered E. coli strain has been developed which is capable of efficiently producing putrescine using renewable methods to an industrial level. This metabolic engineering framework should be useful for developing metabolically engineered microorganisms for the efficient production of other chemicals from renewable resources," he added.
