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, GS Caltex Jointly Develop New Bacteria to Produce Biobutanol
KAIST and GS Caltex, Korea"s second-largest refiner, have jointly developed a new strain of bacteria to produce biobutanol, which is regarded as a promising next-generation biofuel, KAIST authorities said on Monday (June 2).
A research team led by Prof. Sang-Yup Lee of the Chemical and Biomolecular Engineering Department and researchers of GS Caltex succeeded in developing an improved strain of bacteria which enables to produce a large amount of biobutanol in the process of fermenting biomass. The research team has applied for international patent for the new technology.
Biomass refers to living and recently dead biological material that can be used as fuel or for industrial production. It usually refers to plant matter grown for use as biofuel, but it also includes plant or animal matter used for production of fibers, chemicals or heat.
In the 1970s and 1980s when scientists began researching the possibilities of alternative fuels, bacteria were used in the process of fermenting biomass. This ABE (acetone, butanol, ethanol) fermentation process yields butanol, acetone, and ethanol in a ratio of 6:3:1, respectively. Acetone produced in this process is not usable.
The newly developed technology to produce biobutanol has an advantage of lowering production cost by eliminating the process to separate acetone from butanol. This has been made possible by improving the bacteria used for the fermentation in metabolic engineering terms, and producing butanol and ethanol only in a ratio of 6:1, while curbing the generation of acetone.
In comparison with bioethanol, also a biofuel mixture which is currently under widespread use in some countries, butanol is more easily transported with gasoline and diesel through pipelines because of its lower tendency to separate from the fuel when contaminated with water. Butanol is also less corrosive than ethanol, another reason its transport through pipeline is preferable.
Global interest in full utilization of biomass and development of other alternative energy including biobutanol has deepened in recent years, as crude oil prices have skyrocketed to record levels and climate changes resulting from the excessive use of fossil fuel have been causing various problems around the world.

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.
