Flexible Nanogenerator Technology
KAIST research team successfully developed the foundation technology that will enable to fabrication of low cost, large area nanogenerator.
Professor Lee Gun Jae’s team (Department of Materials Science and Engineering) published a dissertation on a nanogenerator using nanocomplexes as the cover dissertation of the June edition of Advanced Materials.
The developed technology is receiving rave reviews for having overcome the complex and size limitations of the nanogenerator fabrication process.
A nanogenerator is an electricity generator that uses materials in the nanoscale and uses piezoelectricity that creates electricity with the application of physical force.
The generation technology using piezoelectricity was appointed as one of top 10 promising technologies by MIT in 2009 and was included in the 45 innovative technologies that will shake the world by Popular Science Magazine in 2010.
The only nanogenerator thus far was the ZnO model suggested by Georgia Tech’s Professor Zhong Lin Wang in 2005.
Professor Lee’s team used ceramic thin film material BaTiO3 which has 15~20 times greater piezoelectric capacity than ZnO and thus improved the overall performance of the device. The use of a nanocomplex allows large scale production and the simplification of the fabrication process itself.
The team created a mixture of PDMS (polydimethylsiloxane) with BaTiO3 and either of CNT (Carbon Nanotube) or RGO (Reduced Graphene Oxide) which has high electrical conductivity and applied this mixture to create a large scale nanogenerator.

High Capacity Molecular Storage Technology Developed by KAIST Professor Omar M. Yaghi
KAIST research team has succeeded in developing the technology that allows high capacity protein storage.
Professor Omar M. Yaghi (Graduate School of EEWS) and his research team succeeded in developing the core technology that enables the storage of various types of proteins by developing a metal organic structure. The result of their research was published in the May edition of Science magazine.
The newly developed technology can store various types and sizes of proteins. This property is expected to pave way to: 1) development of high capacity, high integration drugs 2) development of virus separation compounds 3) selective removal of protein causing negative reactions in the body 4) permanent preservation of rare polymeric proteins, among other expectations.
In addition it becomes possible to selectively remove and preserve all the body’s cells including stem cells which will aid the development of cures for incurable diseases and increase life expectancy and medical technology in general.
Conventional metal-organic structure used 7 Angstrom large small single molecules and therefore could not be used in the storage of large molecules or proteins. Its usability was proven only as potential high capacity gas storage structure. In addition the internal structure of the metal organic structure is cross linked which made it even more difficult to store large proteins within the structure.
Professor Yaghi’s team used molecular structure over 5nm in length in the development of the metal-organic structure to solve the problem associated with size of structure. The ordered structure of the structure’s pore was observed for the first time using Transmission Electron Microscope.
The new structure enables the ordered storage of large proteins and was able to store vitamin and proteins like myoglobin at high capacity for the first time in the world.

Scientists develop highly efficient industrial catalyst
http://english.yonhapnews.co.kr/business/2011/07/14/48/0501000000AEN20110714009600320F.HTML
SEOUL, July 15 (Yonhap) -- South Korean scientists said Friday that they have developed a highly efficient nanoporous industrial catalyst that can have a considerable impact on chemical and oil-refining sectors.
The team of scientists led by Ryoo Ryong, a chemistry professor at the Korea Advanced Institute of Science and Technology (KAIST), said the solid zeolite compound developed in the laboratory has a reaction speed five to 10 times faster than that of conventional materials.
Zeolite, which is made from silica and aluminium, is frequently used as an absorbent, water purifier and in nuclear reprocessing, although it is mainly employed in the chemical industry.
The annual size of the zeolite market is estimated at US$2.5 billion with output using the material topping $30 billion. At present, 41 percent of all catalysts used in the chemical sector are nano-scale zeolite materials.
The KAIST team said that because the new zeolite is made up of different sized pores, the material can be used as a catalyst when existing materials are unable to act as a changing agent.
"Existing zeolites only have pores under 1 nanometer in diameter, but the new material has holes that range from 1 nanometer to 3.5 nanometers, which are all arranged in a regular honeycomb arrangement," Ryoo said. A nanometer is one-billionth of a meter.
He said the ability to have both micro- and meso-sized pores is key to the faster reaction speed that is an integral part of raising efficiency. The South Korean researchers used a so-called surfactant process to make the different sizes of pores.
The development is a breakthrough because researchers and companies such as Exxon Mobil Corp. have been trying to build zeolite with different sizes of pores for the past two decades without making serious headway. There are more than 200 different types of zeolites in the world.
Ryoo, who received funding from the government, has requested intellectual property rights for the discovery, which has been published in the latest issue of Science magazine. He also developed another zeolite in the past that can transform methanol to gasoline up to 10 times more efficiently than existing catalysts.
Exxon Mobil has expressed interest in the two zeolites made by Ryoo"s team. Undisclosed South Korean petrochemical companies have also made inquiries that may lead to commercial development in the future.
"There are some technical issues to resolve, mainly related with mass production and stability," the scientist said.
He said full-fledge production will be determined by how much companies are willing to spend on research to speed up development that can bring down overall production costs.
The KAIST team said it took two years to make the new zeolite, which can be custom made to meet specific needs.

World Research University Heads To Discuss Global Networking at KAIST Symposium
About 70 leaders of the world"s major research universities will discuss how to strengthen and operate global networks to share faculty, students, facilities and other resources for common advancement at a symposium Monday, Sept. 8, at the Westin Chosun Hotel in Seoul organized by KAIST, Korea"s foremost institute of science and technology education and research.
Participants of the 1st International Presidential Forum on Global Research Universities are from 39 universities in 20 countries. They include nine presidents of Korean universities.
The international symposium, the first such event to be held in Korea, will proceed in five panel sessions. The subjects of each session and their keynote speakers are:
-- "Roaming Professorships: To Whose Benefit?" by Dr. John Anderson, president of the Illinois Institute of Technology, USA,-- "Dual Degree Programs: Future Potential and Challenges" by Dr. Paul Greenfield, president of the University of Queensland, Australia, -- "Sharing Facilities and Expertise" by KAIST President Nam Pyo Suh,-- "An Approach to Joint Research Ventures with NASA" by Yvonne Pendleton, NASA, and-- "Globalization through Interfacing with Existing Networking" by Dr. Lars Pallesen, rector of the Technical University of Denmark.
KAIST President Suh said of the purpose of the conference: "Research universities have become global enterprises. Collaborations that were once primarily between individual researchers are now increasingly occurring at institutional and international levels. Similarly, educating students which used to be the responsibility of a single university has now become a multi-institutional undertaking, involving many universities in different countries.
"Now leading research universities in many countries depend on the continuous supply of outstanding graduate students from the "feeder" schools of developing nations. There are concerns that the current system may not be serving the interest and need of some institutions, especially those in developing nations. This should be examined and understood to devise international mechanisms that can accentuate the positive aspects of globalization.
"Through this forum, we hope to forge an international network of universities that will strengthen the effort of individual universities and create alliance for research and education that can become a new paradigm for global collaboration."
Prime Minister Han Seung-soo will give a speech at a dinner after the conclusion of the symposium. President of the Korea International Traders Association Lee Hee-beom will make a welcoming address at the start of the conference.
Co-sponsors of the international university presidents" forum include the Dong-a Ilbo, a major national daily, and the Dong-a Science magazine.
The research universities presidential forum will be followed on Sept. 9 by an international academic workshop at KAIST"s Daejeon campus on EEWS (Energy, Environment, Water and Sustainability).
Under the theme of "Challenges as Opportunities," research teams from MIT, CalTech, the Korean Ministry of Knowledge and Economy, KAIST Institute and KAIST EEWS team will present their research results at the workshop. Major Korean businesses, including SK Energy, GS Caltex and the Samsung Group will also introduce their research programs concerning EEWS, the most pressing prblems of today"s world.
A groundbreaking ceremony will be held at the KAIST campus in the afternoon of the same day for the construction of the KI Building, which will house all the eight research institutes of KAIST. The KI for Bio Century, KI for IT Convergence, KI for Design of Complex Systems, KI for Entertainment Engineering, KI for Eco-Energy, KI for Urban Space and Systems, and the KI for Optical Science and Technology were established between 2006 and 2008. More than 230 professors from 18 departments have actively engaged in research activities in their respective fields.
KAIST will start construction of the Pappalardo Medical Center in a ceremony on Wednesday with the attendance of Mr. Neil Pappalardo, chairman-CEO of Meditech Inc. of the United States who donated $2.5 million for the project. The medical facility for KAIST students, faculty and the residents of the university area will be completed in September 2009.
The President"s Advisory Council (PAC) for KAIST will hold its 3rd general meeting on Sept. 10 to discuss KAIST"s short- and long-term strategies to become the world"s top-ranked research university. The PAC was formed in 2006 with 11 foreign and 14 domestic figures from the business and academic circles.
Foreign PAC members include John Holzrichter, president of Fannie and John Hertz Foundation; Donald C. W. Kim, chairman of AMKOR A&E, Inc.; Chong-Moon Lee, chairman of AmBex Venture Group; Byung-Joon Park, founder of Bureau Veritas CPS, Inc.; Lars Pallesen, rector of the Technical University of Denmark.

Co-sponsors of the International Presidential Forum include the Dong-A Ilbo, a major national daily, and the Dong-A Science Magazine.
Message from KAIST President Suh:
Research universities have become global enterprises. Collaborations that were once primarily between individual researchers are now increasingly occurring at institutional and international levels. Similarly, educating students used to be the responsibility of a single university but has now become a multiinstitutional undertaking, involving many universities in different countries.
These changes are a consequence of globalization and integration of the world’s economy. Temporal andgeographical separations are no longer barriers to the collective generation and transfer of knowledge andenlightened education. It is also a natural response to the demand for educated workforce who can functionin any country.
Current globalization was preceded by the migration of graduate students who were seeking to fulfill theiraspirations for better education at the world’s leading universities. This international movement of studentshas benefited not only students but research universities as well. Now leading research universities in manycountries depend on the continuous supply of outstanding graduate students from the “feeder” schools ofdeveloping nations.
There are some concerns that the current system may not be serving the interest and need of some institutions,especially those in developing nations. This should be examined and understood to devise institutionalmechanisms that can accentuate the positive aspects of globalization.
The purpose of the International Forum of Research University Presidents, which will be held on Sept. 8 inSeoul, Korea, is to identify common issues and opportunities for research universities that further strengthenglobalization of higher education and research. Participants will hear diverse views and ideas and will learnfrom those who have been active in global education and research. Participants also will examine dualdegree programs that are already in place among many universities and the effective implementation of aglobal research network.
Through this process, we hope to forge an international network of universities that will strengthen the effortof individual universities and create alliances for research and education that can become a new paradigm forglobal collaboration.
Looking forward to meeting you in Seoul,
Prof. Nam P. SuhPresidentKAIST

The US Science Magazine Published KAIST News on Nov. 30
An educational innovation of our university arouses world"s interest.
The world science magazine, the U.S Science reports deeply President Suh Nampyo" KAIST reform, fund, tenure review, tuition, admission and faculty recruit in News Focus, internet version on 30 November. There is full text of the news below.http://www.sciencemag.org/cgi/content/full/318/5855/1371
News FocusHIGHER EDUCATION:MIT Engineer Shakes Korean Academia to Its CoreDennis Normile
Radical measures from the new president of the Korea Advanced Institute of Science and Technology are roiling a tradition-bound system
Worldly. To gain stature beyond Korea, KAIST has lured students from Vietnam, China, and Rwanda, among other countries.

DAEJEON, SOUTH KOREA--When the Korea Advanced Institute of Science and Technology (KAIST) announced on 19 November that an entrepreneur had donated $2.5 million to the university with promises of more to follow, it marked the latest in a string of coups for the new president, Suh Nam Pyo. A mechanical engineer on leave from the Massachusetts Institute of Technology (MIT) in Cambridge, Suh has raised an unprecedented amount--$12.5 million--in a country where donations to universities are rare. He"s challenging other traditions as well. For example, KAIST"s latest tenure review turned down several candidates, a shocking move by Korean standards.Suh says he is aiming to make KAIST "as good as the best [universities], including MIT." Many faculty members agree that Suh"s "overall philosophy and vision are correct," says KAIST systems biologist Lee Sang Yup. But there are concerns about how Suh will implement that vision at the 36-year-old university.
The KAIST community has reason to be cautious. In 2004, the university hired Nobel physics laureate Robert Laughlin as president--the first foreigner to lead a Korean university--with a mandate to transform KAIST into a world-class institution. Laughlin, on leave from Stanford University in Palo Alto, California, proposed privatizing KAIST and charging tuition, focusing on commercialization, and tripling undergraduate enrollment (Science, 25 February 2005, p. 1181; 20 January 2006, p. 321). But when Laughlin"s plans failed to materialize, "the faculty was disappointed," says KAIST molecular biologist Chung Jongkyeong. In 2006, the board of trustees decided to seek a new president.
The board turned to Suh. Born in Gyeongju, South Korea, in 1936, Suh moved to the United States with his family as a teenager and earned a doctorate in mechanical engineering from Carnegie Mellon University in Pittsburgh, Pennsylvania. As an MIT professor, Suh has won plaudits for his engineering design theories, earned more than 50 patents, and helped start several companies. In the early 1980s, he was assistant director for engineering at the U.S. National Science Foundation, and he headed MIT"s Department of Mechanical Engineering from 1991 until 2001.
Since arriving at KAIST in July 2006, Suh has opened undergraduate education to non-Korean students for the first time by insisting that many courses be taught in English. Suh decided that students who maintain "B" or better grades would continue to pay no tuition, whereas those with a "C" or below must pay about $16,000 per year starting in February. "We want students to take responsibility for their actions," Suh says.
Agent of change. KAIST"s faculty supports Suh Nam Pyo"s reforms, so far.

A new admissions process may also have broad impact. Previously, KAIST, like most of Korea"s top universities, selected the top scorers in a written exam. Most high school students spend their free time prepping for these tests in cram schools. But Suh says that scores "are a one-dimensional measure" that fails to identify leaders. So candidates for KAIST"s next incoming class were invited to campus this fall for interviews, to give presentations, and to engage in discussions while being observed by faculty members, who made selections based on scores and personal impressions. "We"re looking for future Einsteins and future Bill Gateses," says Suh.An even more radical step was putting teeth into tenure reviews. Traditionally, faculty members in Korea gain tenure after logging enough years. Suh insisted that KAIST professors up for tenure gather endorsements from experts in their field around the world. In September, 11 of 33 applicants were denied tenure and were given a year to find new jobs.
The tenure review "is the beginning of an educational revolution," says KAIST chemist Ryoo Ryong. But he and others worry about the fate of those denied tenure. Suh understands their predicament but is standing firm. The professors who didn"t make tenure "are very good people, but in terms of the standard we set, they"re not as good as we expect our professors to be." He is asking other universities to consider giving these professors a chance.
At the same time, Suh is looking to inject fresh blood--including foreigners--into the 418-strong faculty with a plan to add 300 professors over the next 4 to 5 years. (To expand the school, Suh is striving to win government approval for a doubling of KAIST"s base governmental support of $108 million.) His first catch is Mary Kathryn Thompson, who completed her Ph.D. in mechanical engineering at MIT last year. "It"s an exciting time to be here," says Thompson, who just started studying Korean when she arrived last August.
Although they support Suh"s initiatives, some faculty members chafe at his blunt public comments implying that Korea"s professors take life too easy. "I cannot agree," says Choi Yang-Kyu, an electrical engineer. "Most professors here are working very hard." Biomolecular engineer Kim Hak-Sung adds: "President Suh should have sticks and carrots, not just sticks."
Carrots don"t come cheap. "I"m spending most of my time trying to raise money," Suh says. Part of that effort is wooing private donors. "Giving to universities is not prevalent in Asia, but it is something I"m trying to nurture in Korea," he says. That"s a precedent all of Korea"s universities might want to embrace.

Nerve-protecting gene discovered
Korean scientists for the first time have identified a gene that blocks nerve damage from fevers and the use of narcotics, a state-run research institute said yesterday.
The finding may open the way for new medicine that can prevent the loss of brain function which is frequently caused by excessive stimulation of nerves and abnormally high body temperature.
"The research is in an early stage. But this approach has the potential to develop genetics-based preventatives against brain-attacking diseases," said Kim Jae-seob, a bioscience professor of the Korea Advanced Institute of Science and Technology, who led the study.
The researchers named the gene Pyrexia, which means fever. Kim"s team extracted it from genetically engineered fruit flies using a genome-screening system. In laboratory tests, they found that the gene is activated to 39 degrees Celsius or higher.
The researchers enhanced Pyrexia"s functionality in some fruit flies while removing the gene from others to observe their different reactions when exposed to high temperature.
"The fruit flies without the gene showed severe nerve disorder and suffered paralysis of brain function, while Pyrexia-enhanced flies maintained their normal brain conditions," the professor said.
The researchers got the same result from experiments with human cells, he said.
There are a lot of channel proteins, which enable ions to enter and exit the cell, that react to the level of temperature, but Pyrexia is the first of its kind that actually protects the neurons from external stimulus, he said.
The finding will appear on the March edition of the London-based science magazine Nature Genetics.
