KAIST Scientists Creates Transparent Memory Chip
--See-Through Semis Could Revolutionize Displays A group of KAIST scientists led by Prof. Jae-Woo Park and Koeng-Su Lim has created a working computer chip that is almost completely clear -- the first of its kind. The new chip, called "transparent resistive random access memory (TRRAM), is similar in type to an existing technology known as complementary metal-oxide semiconductor (CMOS) memory -- common commercial chips that provide the data storage for USB flash drives and other devices. Like CMOS devices, the new chip provides "non-volatile" memory, meaning that it stores digital information without losing data when it is powered off. Unlike CMOS devices, however, the new TRRAM chip is almost completely clear. The paper on the new technology, entitled "Transparent resistive random access memory and its characteristics for non-volatile resistive switching," was published in the December issue of the Applied Physics Letters (APL), and the American Institute of Physics, the publisher of APL, issued a press release about this breakthrough. "It is a new milestone of transparent electronic systems," says researcher Jung-Won Seo, who is the first author of the paper. "By integrating TRRAM devices with other transparent electronic components, we can create a totally see-through embedded electronic system." Technically, TRRAM devices rely upon an existing technology known as resistive random access memory (RRAM), which is already in commercial development for future electronic data storage devices. RRAM is built using metal oxide materials between equally transparent electrodes and substrates. According to the research team, TRRAM devices are easy to fabricate and may be commercially available in just 3-4 years. "We are sure that TRRAM will become one of alternative devices to current CMOS-based flash memory in the near future after its reliability is proven and once any manufacturing issues are solved," says Prof. Jae-Woo Park, who is the co-author on the paper. He adds that the new devices have the potential to be manufactured cheaply because any transparent materials can be utilized as substrate and electrode. They also may not require incorporating rare elements such as Indium.

Prof. Kwon Unveils Home-Made Lunar Module
A KAIST research team led by Prof. Se-Jin Kwon at the Department of Aerospace Engineering has unveiled a small lunar module developed in cooperation with engineers at a local company, Space Solutions, university authorities said on Thursday (Nov. 27). The home-made lunar module, the vehicle that conducts survey on the surface of the moon, is 40 centimeters tall and weighs 25 kg. Equipped with a liquid-fuel rocket engine with a maximum thrust of 350 newtons (N), it is capable of carrying objects weighing around 20 kg to the lunar space from the space ship. Professor Kwon"s team held a demonstration of the lander for journalists at a KAIST lab on Friday (Nov. 28). Lunar landers are critical in developing lunar spacecraft, and countries with advanced aerospace technologies have been careful to protect their core technologies. According to Prof. Kwon, every part of the rocket engine, including the catalyst, was home made. The rocket"s propulsion system features a state-of-the-art propellant valve developed by Space Solutions, which enables thrust control. Lunar modules between the 100 and 200 kilogram range, developed by NASA (U.S. National Aeronautics and Space Administration), costs around $100 million, said Kwon. "It is expensive to guarantee the safety of developers of an American module because the fuel contains carcinogens. But the rocket engine created by KAIST team could cut development costs to about half that because it is powered by environmentally friendly fuel," he said. The lander, product of a six-year-long effort, represents remarkable advancement in the technology for developing spacecraft for lunar missions.

KAIST Collaborating with U.S. Universities to Advance Humanoid Robotics
Hubo, a life-size walking bipedal humanoid robot, is perhaps the best-known character in Korea that KAIST has ever produced. It was shown to the government heads of the Asia-Pacific region during the APEC held in Busan, Korea, in 2005 and appeared at the hit concerts of the pop singer Jang-Hoon Kim. The humanoid robot is soon likely to catch the fancy of Americans as a U.S. government-funded project seeks to create a Hubo that can work and interact with people in collaboration with Korean scientists. "We are going to give the brains to Hubo. (Japanese) Asimo can do only pre-programmed actions. We want to create a Hubo that can help people, interact with people," said Prof. Paul Oh of the Department of Mechanical Engineering & Mechanics at Drexel University in Philadelphia and leader of the five-year international project which was launched in November 2007. The U.S.$2.5 million project is funded through the Partnership for International Research and Education (PIRE) Program of the National Science Foundation (NSF) of the United States. It brings together world-renowned experts in humanoid design and information technologies. "Dr. Jun-Ho Oh"s lab at KAIST (that has created Hubo) is the world"s leader in humanoid design and the U.S. has advanced technologies in the areas such as artificial intelligence, mechanical learning and robot vision. Combining the strengths of the two countries can create a synergy effect and develop a more advanced humanoid robot," said Paul Oh. He is currently serving as Program Director of Robotics of the NSF which is overseeing robotics research (non-military) in the U.S. consisting over 150 robotics faculty. Paul Oh"s research team consists of experts from five U.S. universities -- Drexel, Bryn Mawr College, Colby College, the University of Pennsylvania and Virginia Tech -- and KAIST. Leading a delegation of six professors and eight students, Dr. Paul Oh made a two-day visit to KAIST on Nov. 18-19 to review the progress of the project and have a technical meeting with participants. "The U.S. universities participating in this program are scattered across the nation. So we decided to have a technical meeting here in Korea," he said. Asked the reason why he chose KAIST as a partner for the program, Dr. Oh said that KAIST is willing to open Hugo to international researchers, whereas in Japan only Honda engineers are allowed to touch Asimo, which is a humanoid robot created by Honda Motor Company. The project is to establish no barrier for roboticists anywhere in the world to pursue the humanoid research; a suite of humanoid platforms will be available for researchers to develop and advance capabilities like locomotion and human-robot interaction. The team has been initially involved in development of three tools, all of which are based on the Hubo platform, in order to kick-start humanoid research in the U.S. They are the Mini-Hubo (a small, light-weight and affordable humanoid purchasable at the price lower than $8,000), On-Line Hubo (a program to operate Hubo online) and Virtual Hubo (a simulation program to do researches in cyberspace). As the first outcome of the project, the Mini-Hubo is expected to be released in the U.S. around next April. Another important purpose of the PIRE program is to seek transformative models to train scientists and engineers to effectively work in global multi-disciplined design teams. To this end, an aggregate number of 20 students from U.S. universities are to stay at the KAIST during the next five years, with two students taking turns on a six-month term. "I was really amazed how much work is done with small funding here. This is really an excellent example to learn," said Roy Gross, an undergraduate from Drexel who has been staying at Prof. Oh"s Lab for the past three months.

KAIST Research Team Unveils Method to Fabricate Photonic Janus Balls
A research team led by Prof. Seung-Man Yang of the Department of Chemical and Biomolecular Engineering has found a method to fabricate photonic Janus balls with isotropic structural colors. The finding draws attention since the newly-fabricated photonic balls may prove useful pigments for the realization of e-paper or flexible electronic displays. The breakthrough was published in the Nov. 3 edition of the science journal "Advanced Materials." The Nov. 6 issue of "Nature" also featured it as one of the research highlights under the title of "Future Pixels." Prof. Yang"s research team found that tiny marbles, black on one side and colored on the other, can be made by "curing" suspensions of silica particles with an ultraviolet lamp. When an electric field is applied, the marbles line up so that the black sides all face upwards, which suggests they may prove useful pigments for flexible electronic displays. The researchers suspended a flow of carbon-black particles mixed with silica and a transparent or colored silica flow in a resin that polymerizes under ultraviolet light. They then passed the mixture through a tiny see-through tube. The light solidified the silica and resin as balls with differently colored regions, each about 200 micrometers in diameter. Over the last decades, the development of industrial platforms to artificially fabricate structural color pigments has been a pressing issue in the research areas of materials science and optics. Prof. Yang, who is also the director of the National Creative Research Initiative Center for Integrated Optofluidic Systems, has led the researches focused on fabrication of functional nano-materials through the process of assembling nano-building blocks into designed patterns. The "complementary hybridization of optical and fluidic devices for integrated optofluidic systems" research was supported by a grant from the Creative Research Initiative Program of the Ministry of Education, Science & Technology.

KAIST Team Identifies Nano-scale Origin of Toughness in Rare Earth-added Silicon Carbide
A research team led by Prof. Do-Kyung Kim of the Department of Materials Science and Engineering of KAIST has identified the nano-scale origin of the toughness in rare-earth doped silicon carbide (RE-SiC), university sources said on Monday (Oct. 6). The research was conducted jointly with a U.S. team headed by Prof. R. O. Ritchie of the Department of Materials Science and Engineering, University of California, Berkeley. The findings were carried in the online edition of Nano Letters published by the American Chemical Association. Silicon carbide, a ceramic material known to be one of the hardest substances, are potential candidate materials for many ultrahigh-temperature structural applications. For example, if SiC, instead of metallic alloys, is used in gas-turbine engines for power generation and aerospace applications, operating temperatures of many hundred degrees higher can be obtained with a consequent dramatic increase in thermodynamic efficiency and reduced fuel consumption. However, the use of such ceramic materials has so far been severely limited since the origin of the toughness in RE-SiC remained unknown thus far. In order to investigate the origin of the toughness in RE-SiC, the researchers attempted to examine the mechanistic nature of the cracking events, which they found to occur precisely along the interface between SiC grains and the nano-scale grain-boundary phase, by using ultrahigh-resolution transmission electron microscopy and atomic-scale spectroscopy. The research found that for optimal toughness, the relative elastic modulus across the grain-boundary phase and the interfacial fracture toughness are the most critical material parameters; both can be altered with appropriate choice of rare-earth elements. In addition to identifying the nano-scale origin of the toughness in RE-SiC, the findings also contributed to precisely predicting how the use of various rare-earth elements lead to difference in toughness. University sources said that the findings will significantly advance the date when RE-SiC will replace metallic alloys in gas-turbine engines for power generation and aerospace applications.

KAIST Professor Exposes Structural Dynamics of Protein in Solution
-- Dr. Hyot-Cherl Ihee"s 3-Year Research Is Valuable in Pharmaceutical Application Prof. Hyot-Cherl Ihee and his team at the Department of Chemistry, KAIST, has successfully unveiled the structural dynamics of protein in solution as a result of more than three years" research work. Nature Methods, a sister publication of the authoritative science magazine Nature, published the treatise, titled "Tracking the structural dynamics of proteins in solution using time-resolved wide-angle X-ray scattering" in its Sept. 22 online edition. The research paper will be carried in the magazine"s printed version in its October edition, according to Dr. Lee who is its correspondence author. In May 2005, Prof. Ihee successfully photographed the structural dynamics of protein in solid state and his findings were published in the Proceedings of National Academy of Science of the United States. As protein normally exists in human body in solution, not in solid state, he directed his research to developing the technology to capture protein"s dynamics in resolved state. In July that year, Prof. Ihee succeeded in measuring the structural changes of simple organic molecules in real time. He further developed the technology to uncover the structural dynamics of hemoglobin, myoglobin and cytochrome C. Prof. Ihee"s research, helped with the Education-Science-Technology Ministry"s Creative Research Promotion Fund, can be applied to new pharmaceutical development projects as well as nanotechnology development, according to KAIST officials. Prof. Ihee who earned his doctorate at California Institute of Technology in 1994 began teaching at KAIST in 2003. He won the Young Scientist Award given by the Korean government in 2006.
