The school topped Times Higher Education’s list of the world’s b..
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 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..
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..
POSETCH researchers have successfully developed the particle beam technique to eliminate nanometer-sized contaminant particles (CPs) of nano-scale devices, for the first time in the world.A research team led by Professor Jin Won Lee of the Department of Mechanical Engineering has succeeded in developing the technology to completely remove 10 nm-sized CPs using a revolutionary beam technique that uses nanometer-sized bullet particles (BPs) moving at supersonic speed. The research result has been published in the online edition of Nanoscale Research Letters on Apr. 11.Due to the attraction by su..
The research team of Professor Hyung Joon Cha (CE), Prof. Dong-Woo Cho (ME), and Prof. Rhie, Jong Won (The Catholic University of Korea) succeeded in developing functional three-dimensional scaffolds that enhance regeneration of bone tissue. Using mussel adhesive proteins, it is safe for the human body. It is also proven to be remarkable in adhesion and coating. This research was published in the Apr. 2 online version of Acta Biomaterialia, a renowned academic journal in the field of body materials.The research team affixed the stem cell on the surface of the polymer using the mussel-extracted..
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 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..
