Professor Soon-Heung Chang meets with Bill Gates and discusses possible collaboration
Professor Soon-Heung Chang from the Department of Nuclear and Quantum Engineering, KAIST, who is also the president of Korea Nuclear Society (KNS), met Bill Gates, the co-founder and former chief executive officer (CEO) of Microsoft, on August 16, 2012 and discussed ways to cooperate for the development of a sodium-cooled fast reactor (SFR), a next generation nuclear power reactor. According to Professor Chang, Bill Gates was amazed at Korea’s successful bids for nuclear power plants in the United Arab Emirates, even though Korea was a latecomer in the field of nuclear power. Bill Gates also showed a keen interest in Korea’s low electricity rates. Gates focuses on solving fundamental problems in order to help improve the quality of life for humanity, rather than short-term temporary solutions, through infrastructure development such as energy. Particularly, he considers nuclear power as one of the most effective ways to supply clean energy which can provide electricity at a low cost while keeping carbon dioxide emission levels much lower than fossil fuels. Bill Gates is a primary investor for an energy company called “TerraPower” based in Bellevue, Washington. TerraPower develops and commercializes nuclear power technology for a traveling wave reactor (TWR) that is designed to use spent fuels, i.e., depleted uranium, and runs technically “forever” because once fueled, the reactor does not need to be refueled for over 50 years. TerraPower’s TWR is to use metallic fuel, and Korea is the only country that currently develops SFR (KALIMER 600) using metallic fuel. “Korea has an outstanding supply chain for the entire lifecycle of a nuclear power station from equipment manufacturing to operation,” said Professor Chang, while emphasizing the synergistic effects of forming partnership between Korea and TerraPower. Professor Chang emphasized that Korea should create an opportunity based on lessons learned from the Fukushima crisis and actively move forward to achieve its leading position in the field of next generation nuclear reactors. He said that cooperation with Bill Gates will be a significant step towards the development of next generation nuclear reactors. About Sodium-cooled Fast Reactor (SFR) Sodium-cooled Fast Reactor (SFR) is a next-generation nuclear power reactor that will use spent fuels from conventional reactors. Arrangement of a fuel recycling system in conjunction with currently-developing pyroprocessing technology would enable U-238, which makes up over 99% of natural uranium, to be used as a nuclear fuel. This would greatly reduce the toxicity and volume of spent fuels by up to 1,000 times and 100 times respectively when compared to existing reactors. This is truly a breakthrough innovation in spent fuel disposal and recycling.

KAIST researchers verify and control the mechanical properties of graphene
KAIST researchers have successfully verified and controlled the mechanical properties of graphene, a next-generation material. Professor Park Jung Yong from the EEWS Graduate School and Professor Kim Yong Hyun from the Graduate School of Nanoscience and Technology have succeeded in fluorinating a single atomic-layered graphene sample and controlling its frictional and adhesive properties. This is the first time the frictional properties of graphene have been examined at the atomic level, and the technology is expected to be applied to nano-sized robots and microscopic joints. Graphene is often dubbed “the dream material” because of its ability to conduct high amounts of electricity even when bent, making it the next-generation substitute for silicon semiconductors, paving the way for flexible display and wearable computer technologies. Graphene also has high potential applications in mechanical engineering because of its great material strength, but its mechanical properties remained elusive until now. Professor Park’s research team successfully produced individual graphene samples with fluorine-deficiency at the atomic level by placing the samples in Fluoro-xenon (XeF2) gas and applying heat. The surface of the graphene was scanned using a micro probe and a high vacuum atomic microscope to measure its dynamic properties. The research team found that the fluorinated graphene sample had 6 times more friction and 0.7 times more adhesiveness than the original graphene. Electrical measurements confirmed the fluorination process, and the analysis of the findings helped setup the theory of frictional changes in graphene. Professor Park stated that “graphene can be used for the lubrication of joints in nano-sized devices” and that this research has numerous applications such as the coating of graphene-based microdynamic devices. This research was published in the online June edition of Nano Letters and was supported by the Ministry of Science, Technology, and Education and the National Research Foundation as part of the World Class University (WCU) program.

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.

Seeing Inside Cells with Fiber Optics
Professor Jiho Park’s research team was successful in receiving minute optical signals from inside the cell using optical nano fibers. Through the invention of this technology, we can now look inside cells in high resolution without the use of equipment such as endoscopes that damage cells. We will be able to study the biological phenomena within cells, and thus cure diseases more effectively. Recently, ultra high resolution microscopes have been used to analyze incubated cells. However, because of the need for a very complex and large system, it had been impossible to monitor cells in the less transparent areas of the body in real time. The research team created the wire with a semiconductor created with tin oxides to be only 100 nanometers in diameter (1nanometer= 1/1billion meters). The nanowire is connected to the end of the optical fiber, and the light that comes through the optical fiber is transmitted to particular spots in the cell, and the optical signals from the cell are retrieved back from the cell as well Together with this, based on the fact that nanowires do not damage cells, the research team covered the end of the wire with a photo reactive material and entered this into the cell. They were able to check that the material reacted to light and entered the cell when they transmitted light Accordingly, this showed the possibilities of the use of this technology as a method of treatment to effectively transfer the medication into the cells. Prof. Jiho Park stated that “in this research, we only used cells incubated outside the human body, but soon we will use this technology to stimulate and control cells within the body in a minute scale” as well as that “soon, we will be able to study the biological phenomena inside a cell to study diseases and apply this to cure them more effectively”. This research result has been published in the online publication of ‘Nature Nanotechnology’ on December 18. This study was done through the cooperation of various schools. Besides Prof. Jiho Park, Prof. Seungman Yang from the Biochemistry department, and Doctor Chuljoon Huh from KAIST, Prof. Yeonho Choi from Biomedical Science department of Korea University, Professor Peidon Yang and Doctor Ruoxue Yan from UC Berkeley’s chemistry department, and Luke Lee from UC Berkeley’s bioengineering department participated in the project.

Ten Breakthroughs of the Year 2011 by Science
Porous Zeolite Crytals Science, an internationally renowned scientific journal based in the US, has recently released a special issue of “Breakthrough of the Year, 2011,” dated December 23, 2011. In the issue, the journal introduces ten most important research breakthroughs made this year, and Professor Ryong Ryoo, Department of Chemistry at KAIST, was one of the scientists behind such notable advancements in 2011. Professor Ryoo has been highly regarded internationally for his research on the development of synthetic version of zeolites, a family of porous minerals that is widely used for products such as laundry detergents, cat litters, etc. Below is the article from Science, stating the zeolite research: For Science’s “Breakthrough of the Year, 2011”, please go to: http://www.sciencemag.org/site/special/btoy2011/ [Excerpt from the December 23, 2011 Issue of Science] Industrial Molecules, Tailor-Made If you ever doubt that chemistry is still a creative endeavor, just look at zeolites. This family of porous minerals was first discovered in 1756. They"re formed from different arrangements of aluminum, silicon, and oxygen atoms that crystallize into holey structures pocked with a perfect arrangement of pores. Over the past 250 years, 40 natural zeolites have been discovered, and chemists have chipped in roughly 150 more synthetic versions. View larger version: In this page In a new window Assembly required. Porous zeolite crystals are widely used as filters and catalysts. This year, researchers found new ways to tailor the size of their pores and create thinner, cheaper membranes. CREDIT: K. VAROON ET AL., SCIENCE334, 6052 (7 OCTOBER 2001) This abundance isn"t just for show. Three million tons of zeolites are produced every year for use in laundry detergents, cat litter, and many other products. But zeolites really strut their stuff in two uses: as catalysts and molecular sieves. Oil refineries use zeolite catalysts to break down long hydrocarbon chains in oil into the shorter, volatile hydrocarbons in gasoline. And the minerals" small, regularly arranged pores make them ideal filters for purifying everything from the air on spaceships to the contaminated water around the nuclear reactors destroyed earlier this year in Fukushima, Japan. Zeolites have their limitations, though. Their pores are almost universally tiny, making it tough to use them as catalysts for large molecules. And they"re difficult to form into ultrathin membranes, which researchers would like to do to enable cheaper separations. But progress by numerous teams on zeolite synthesis this year gave this “mature” area of chemistry new life. Researchers in South Korea crafted a family of zeolites in which the usual network of small pores is surrounded by walls holed with larger voids. That combination of large and small pores should lead to catalysts for numerous large organic molecules. Labs in Spain and China produced related large- and small-pore zeolites by using a combination of inorganic and organic materials to guide the structures as they formed. Meanwhile, researchers in France and Germany discovered that, by carefully controlling growth conditions, they could form a large-pore zeolite without the need for the expensive organic compounds typically used to guide their architecture as they grow. The advance opens the way for cheaper catalysts. In yet another lab, researchers in Minnesota came up with a new route for making ultrathin zeolite membranes, which are likely to be useful as a wide variety of chemically selective filters. This surge of molecular wizardry provides a vivid reminder that the creativity of chemists keeps their field ever young. Related References and Web Sites
