Professor Kijung Yong (CE) and his research team succeeded in developing a nonvolatile memory cell which is waterproof and maintains information without power supply. Nonvolatile memory cells could be used in production of waterproof computers and smart phones by using nanotechnology.Memory cells currently used are vulnerable to water. To solve this problem, the research team synthesized the tungsten oxide semiconductor using natural effects called the Lotus Effect, an imitation of lotus leaves, which could wash the dust off the surface without wetting it. In addition, they developed resistive..
Professor Hyun M. Jang of the Department of Material Science and Engineering and a research team led by Jung-Hoon Lee, advised by Prof. Jang, recently discovered that Samarium ferrite (SmFeO3) is a multiferroics exhibiting connection between the order parameters. The result from Prof. Jang’s experiment was posted on Physical Review Letters, an authoritative paper in the physics area.Since SmFeO3 consists of orthorhombic structure, it has been known as material without magnetization; however, Prof. Jang and his research team found it actually has electrical polarization without any electr..
A new leaf-mustard kimchi season is here, stimulating appetites with the unique flavor and aroma of leaf mustard and ground red chili, plus the promise of enriched calcium.The joint research by Professor Youngsook Lee of the Department of Life Science. and Dr. Won-Yong Song and Prof. Martinoia of University of Zurich have created a way for producing the calcium-rich product.The research team found that the protein, BjPCR1, facilitates transportation to calcium absorbed from root hair of plants to inner cells. Prof. Lee’s research team demon-strated the fact that BjPCR controls the transp..
Professor Kwan Hyoung Kang of the Department of Mechanical Engineering developed anelectrohydrodynamic (EHD) pumping method for dielectric (or non-polar) liquids utilized for micro fingers of microsurgical robots. He presented a new way which relies on the EHD flow generated by the filed dependent electrical conductivity.The EHD pump is a device that converts electrical energy to mechanical energy indirectly, and it is required for the cooling system of microelectronic devices for chemical and biological analysis and micropumping of organic solvents.The results of this research are significant..
The HangulBot, developed by the research team of Professor Sonya S. Kwak (HSS), won the Delegate’s Choice prize on Dec. 8 at the International Conference on Social Robotics 2011 held in the Netherlands.The robot, developed by Prof. Kwak, Song Young-bin (CSE 08), Park Joon-sin (ME 09), Eun Ho Kim (KAIST), and Ji Myung Kim (KAIST), was designed for children and non-Koreans. By rotating and rearranging a consonant block and a vowel block, learners can understand the concept of the phonetic aspect of the Korean language in a short time.The robot was designed to perceive the arrangement of th..

By JOYCE LAUHONG KONG — There is one element that links the schools that top university rankings: They tend to be old.Last week, two new rating systems — from Times Higher Education and QS World University Rankings — looked exclusively at schools less than 50 years old for the first time.Fifty may be middle age in some circles, but is positively adolescent for a university. Times Higher Education claims that its list “provides a unique insight into who the futur..
