Storing Stably Hydrogen Atoms in Icy Materials Discovered
KAIST, Aug. 8, 2008 -- A KAIST research team led by Prof. Huen Lee of the Department of Chemical & Biomolecular Engineering has discovered that icy organic hydrates, which contain small cages that can trap guest molecules, can be used to create and trap hydrogen atoms at higher temperatures.
The properties and reactions of single hydrogen atoms are of great scientific interest because of their inherent quantum mechanical behavior; experimentally, they can be generated and stabilized at very low temperatures (4 K) by high-energy irradiation of solid molecular hydrogen.
The finding was reported in the journal of American Chemical Society and featured in the "Editor"s Choice" in the July 11 issue of Science as a recent research highlight.
Hydrogen is a clean and sustainable form of energy that can be used in mobile and stationary applications. Hydrogen has the potential to solve several major challenges today: depletion of fossil fuels, poor air quality, and green house gas emissions.
However, the trapping of hydrogen atoms in crystalline solid matrix has never been attempted mainly because of experimental difficulties in identifying the generated hydrogen atoms with either spectroscopic or microscopic technique.
"To overcome the barriers and limitations of the existing storage approaches, we have continuously attempted to find the new hydrogen storage media such as icy powders and other related inclusion compounds," said Prof. Lee
The discovery follows the breakthrough concept Prof. Lee"s research team proposed in Nature in 2005 to use pure ice to capture and store hydrogen molecules. At moderate temperature and pressure conditions small guest molecules are entrapped in pure ice powders to form the mixed icy hydrate materials.
"Stable existence of single hydrogen molecule/radical in icy crystalline matrices may offer significant advantages in exploring hydrogen as a quantum medium because icy hydrogen hydrates can be formed at milder conditions when compared with pure solid hydrogen, which requires the ultra low temperature of 4.2 K," said Prof. Lee.
The novel design and synthesis of ionic and radicalized icy hydrates are expected to open a new field for inclusion chemistry and ice-based science and technology. Specifically, the fact that hydrogen atoms can be stably stored in icy materials might provide versatile and practical applications to energy devices including fuel cells, ice-induced reactions, and novel energy storage process, according to the KAIST professor.

KAIST to hold 2008 Int
KAIST, Korea"s premier science and technology research university, will hold the 1st International Presidential Forum on Global Research Universities at the Westin Chosun Hotel in Seoul on Sept. 8, 2008. Presidents of research universities in all regions of the world have been invited to the conference aimed primarily at identifying common issues and opportunities in strengthening globalization of higher education and research.
Participants in the forum will exchange views and ideas on how to build and utilize global research network to promote the sharing of expertise and facilities, conduct joint researches and effectively implement dual degree and roaming professorship programs.
KAIST President Dr. Nam P. 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 form 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 alliances for research and education that can become a new paradigm for global collaboration."
Keynote presentations will be made on the following five major subjects: -- Roaming Professorship-- Dual Degree Program-- Sharing Facilities and Expertise-- Joint Research, and-- Globalization through Interfacing with Existing Networking
Leaders of the world"s major education and research institutions have been asked to lead panel discussions with their rich experiences in globalization programs.
Following the conference in Seoul, participants are invited to come to the KAIST campus in Daejeon, about 150 kilometers from Seoul, where a symposium on EEWS (environment, energy, water and sustainability) will be held to examine the progress in interdisciplinary research activities in these vital problems facing the mankind and look for a new direction in international collaboration.
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

Super-Fast Internet Data Chip Developed
A KAIST research team led by Prof. Kyoung-Hoon Yang of the Electrical Engineering & Computer Science Department developed a super-fast chip that could lead to huge advancements in broadband Internet technology, the Korean Ministry of Education, Science and Technology said on Thursday (June 26).
The multiplexer chip is the first of its kind to be developed using the quantum effect of resonant tunnelling diode, according to the Ministry.
The integrated circuit chip built at the university laboratory has an operating speed of 45 gigabits per second (Gb/s), while using roughly 75 percent less energy than the previous version. The speed enables the transfer of about 4 full-length movies in one second.
The best operational broadband Internet services provide users with data transfer speed of 40 Gb/s, while most other high-speed online connections offer 10 Gb/s.
"Besides speed, the greatest achievement is low energy use," Prof. Yang said. He stressed that energy use in chips is a crucial factor because power creates heat that can melt circuits and make them inoperable.
"By cutting down on energy use, the new chips can be made smaller and with faster data transfer speed," the scientist said.
He added that efforts are underway to increase operational speed to 100 Gb/s, with energy consumption to be cut to 10 percent of current chips like the high electron mobility transistor, the heterojunction bipolar transistor and the complementary metal oxide semiconductor.
The researcher speculated that such revolutionary chips could be developed in 1-2 years and become the new benchmark in this field since existing chips have limited development capabilities.
The project has received funding from the Education-Science-Technology Ministry since 2000. The Ministry"s financial support will last until 2010.

KAIST, ICU Agree to Merge
KAIST and the Information and Communications University, a state-run institution, decided to merge as they signed a memorandum of understanding for unification at the Westin Chosun Hotel in Seoul on May 23.
The MOU signing ceremony was attended by representatives of the two universities and related high-ranking government officials from the Ministry of Knowledge Economy and the Ministry of Education, Science and Technology.
Under the agreement, the two universities will form a joint committee to complete the merger process by the end of this year. According to the MOU, ICU will become the "IT Convergence Campus" (ICC) which will include KAIST"s IT related departments and research institutes. The projected ICC will be headed by a KAIST vice president, KAIST authorities said.
With the merger, the number of KAIST students in the IT area will increase to 2,850 from 1,951, while the number of IT-related faculty members will rise to 157 from 99.
ICU was established in 1997 by the Korean Ministry of Information and Communication, the Electronics and Telecommunications Research Institute, and some major Korean IT companies. Located in Daedeok Science Town in Daejeon where KAIST is also situated, ICU started as a graduate school and added the undergraduate course in 2002. It currently has a total enrollment of 1,121 students -- 481undergraduate students, 324 graduate students and 316 doctorate students.
KAIST said that it will treat ICU professors and staff equally after the merger. This year, the two universities will separately conduct freshmen recruitment procedures for 2009, but will then unify recruitment.
The unification of the two institutions is expected to give KAIST the competitive edge through a larger faculty, student body, and expanded facilities.
The agreement put an end to extended negotiations for merger which started in July 2006. The talk of merging the two universities surfaced when the Board of Audit and Inspection concluded that the government"s direct financial support for ICU was unlawful as ICU was established as a private school. When ICU was established in 1997, the Ministry of Information and Communication provided 200 billion won as the basic endowment and has continually provided 10 billion won in operating funds each year.

2008 Commencement Ceremony Held
The 2008 KAIST Commencement Ceremony was held on Feb. 29 at the KAIST Amphitheater in the presence of KAIST President Nam Pyo Suh, U.S. Ambassador to Korea Alexander Vershbow, alumni representatives and parents.
Other dignitaries on hand included National Assemblymen Sang-Kee Suh, Chang-Sun Hong and Sang-Min Lee; and Daejoen City Major Sung-Hyo Park.
President Suh and Vice President Soon-Heung Chang presented degrees to each of the 1,321 graduates (200 doctors, 725 masters and 396 bachelors) instead of just to representatives. Since its inception in 1971, KAIST has produced 7,067 Ph.D. graduates, 18,636 master"s degree holders and 8,998 bachelor"s degree holders. This year, 40 percent of the Ph.D. graduates, 79, were in their twenties upon graduation.
President Suh called on the graduates to return the favor they received from society by making their share of contributions to humanity. "You were chosen to be students of this unique university because the Korean people -- not only KAIST professors and staff, but also ordinary taxpayers -- believe that outstanding young people like you can change the world in which we live for the better. Now it is time for you to pay back their support," he said.
Notable graduates of this year include So-Yeon Yi, 29, the first Korean female astronaut candidate, who earned her doctorate degree in bio and brain engineering. She was granted a special award in recognition of her role in advancing space science in Korea but she could not attend the graduation ceremony due to her training schedule in Russia which will continue until April.
Eun-Gyu Oh, 26, was the youngest doctorate recipient in the ceremony and Won Hye-jeong, 21, recorded the top undergraduate GPA with a score of 4.20 over 4.3. Civil and environmental engineering major Seung-Hee Park, 28, published a total of eight papers in major international journals while attending KAIST and two more papers are currently under review.
So-Yeon Yi said: ``I frequently stayed up all night to research and write the paper. It was tough experience for me. Thanks to ceaseless support from professors and colleagues, however, I was able to complete the task,"" she said. ``I have done my best in studying, exercising and so on. I"m sure that my active, participatory attitude brought about this honorable moment.""
She is now training at Gagarin Cosmonaut Training Center near Moscow as a replacement astronaut in case Koh San, 31, who is to be the first Korean astronaut, is unable to go into orbit.
Koh and Yi were selected from more than 36,000 applicants last year. Koh was finally picked as the primary candidate last September. The two are serving as space ambassadors appointed by the Ministry of Science & Technology.
