Professor Yoon-Seok Chang (School of Environmental Science and Engineering), a worldwide authority on dioxin, has been selected as a first prize winner of the academic research award by the Korean Society of Environmental Engineers. An awards ceremony was held at the Kimdaejung Convention Center on August 21st. Over the past 30 years, Professor Chang has published nearly 200 SCI papers and studies which include analyses of toxic substances such as dioxins and other endocrine on human health. His study of the environmental risks of bio-nanomaterials has recently received academic attention.
Despite having numerous advantages, clinical applications of 3D printed scaffolds for tissue regeneration are extremely rare. A team consisting of POSTECH Professor of Mechanical Engineering Dong-Woo Cho, Professor Jong Won Rhie of the Department of Plastic Surgery College of Medicine at the Catholic University of Korea, and Won-Soo Yun of T&R Biofab Co., have applied 3D printing technology for correcting an asymmetric face caused by the removal of a tumor in a patient about a decade ago.The patient had trauma in the right malar region and because of this his eyes were misaligned. In this ..
Professor Suk Bong Hong(CE and School of Environmental Science and Engineering) and Hyung Ki Min(CE, Ph.D. candidate) succeeded in converting meta-xylene to para-xylene using zeolite catalyst based on gas chromatography-mass spectrometry-computer(GC-MS-CPU) and isotope exchange method. Para-xylene which is used to make polyester fibers, plastic bottles, and films is a basic petrochemical material made through isomerization of meta-xylene, whose mechanism has been merely a hypothesis. Unlike other technologies, this technology can now be realized ex hypothesi.The research team is receiving atte..
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..
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 Sangmin Jeon (CE) and Jinmyoung Joo (Post Doc.) have developed the technology that diagnoses cancer by using micro-oscillators made of photo- catalytic silicon and nanoparticle on the inside and magnetic material on the outside. This technology, published on ACS Nano, attracted academic attention because it could be applied to cancer diagnosis at once as well as early detection, which is crucial in cancer treatment.When patients suffer from cancer, the concentration of specialized proteins in blood and other body fluids increases. This technology uses the concentration of the protein..
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..
