A research te-am that consists of Professor Tae-Woo Lee (MSE), Tae-Hee Han (MSE Ph.D. ca-ndidate), Prof. Jong-Hyun Ahn (SKKU), and Prof. Byung Hee Hong (SNU) has developed graphene into organic light-emitting diode (OLED) and flexible, white light with it for the first time.This team noticed that the inefficiency of graphene in OLED can be resolved by replacing conventional indium tin oxide anodes with high-work-function, low-sheet-resistance graphene anodes. The team improved the luminous efficiencies to 37.2 Im/W for fluorescent and 102.7 Im/W for phosphorescent devices, which are higher tha..
Professor Nam -Ki Lee (i-Bio and Physics) su- cceeded in find- ing the step-by-step processes of neurotransmitt- ers in the brain cells through the single molecule technique, which had previously been unknown. This principle allows for possibilities to understand the causes of brain cell damage when patients suffer from intractable cerebropathy such as dementia.Prof. Lee’s research team jointed with Prof. Yeon-kyun Shin (KIST) to discover the fact that synaptotagmin-1, which is protein in biological membrane, controlled fusion of cell membrane in process of releasing chemicals by gradati..
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..
POSTECH researchers have found a way to tightly fix bio materials by using mussel adhesive proteins (MAPS).Professor HyungJoon Cha of the Department of Chemical Engineering had developed sticky nanofibrous scaffold based on MAPS, which can be functionalized with diverse types of biomolecules. The paper supported by “Marine Bioengineering Technology Project” under the Ministry of Land, Transport, and Maritime Affairs appeared in the Angewandte Chemie International Edition published online on Oct. 19.Nanofibers are a promising tool for tissue engineering applications, and various stu..
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 HyungJoon Cha of the Department of Chemical Engineering has devised a new technique which combines Mussel Adhesive Protein (MAP) and antibody-binding protein to pin down an antibody on diverse surfaces coated with a new linker protein (BC-MAP).BC-MAP is a linker material to immobilize y-shaped antibodies onto immunosensors such as a pregnancy test which examines for infection by antigen-antibody reaction. In order to work properly, antibodies are supposed to be exactly immobilized onto surfaces.Previously, antibody-binding protein did not immobilize an antibody depending on the surfa..
Asmart nanomedicine customized for liver diseases has been developed by Professor Sei Kwang Hahn’s research team in the Department of Materials Science and Engineering. Hyaluronic acid is a bio-polymer of high biocompatibility and stability, and can be target-specifically delivered to liver tissues. Capitalizing on this characteristic of hyaluronic acid, Prof. Hahn built a liver-targeted drug delivery system, which is expected not only to reduce serious side-effects of the conventional uncustomized medications, but also to advance the effectiveness of the drug for hepatitis, liver cirrho..
It is not uncommon for diseases such as diabetes, hypertension and cancer to develop complications. Recently, a research team led by Professor Sanguk Kim of Department of Life Science successfully devised a method for predicting disease complications based on comorbid disease pairs by employing a network medicine approach. Jointly with Professor Sung Ki Jang of Life Science, PhD candidate Solip Park, and Professor Juyong Park of Kyung Hee University, Professor Kim published a paper, ‘Protein localization as a principal feature of the etiology and comorbidity of genetic diseases’ in..
Water probably is the greatest enemy for most electrical devices; water short-circuits electric devices. Therefore the demand is high for developing water-resistant components, and in particular, those to be used for expensive, high-performance electronic devices. Professor Kijung Yong of Department of Chemical Engineering and PhD candidate Seunghyup Lee have utilized the ‘lotus leaf effect’ with nano materials and manufactured an electronic device that shows stable performance even when soaked in water. The result was published online in Advanced Materials, a renowned journal in m..
