A research team comprised of Professor Taiho Park, Jongchul Lim, and Taewan Kim of the Department of Chemical Engineering, reported a novel way to solve both dye regeneration and electron transport problems simultaneously using a “ladder” concept. The paper was published in the December issue of Energy & Environmental Science. Next generation energy devices should be based on clean and sustainable solar energy. Among the conventional solar energy device, dye-sensitized solar cells (DSCs) have lots of advantages with higher power conversion efficiency such as chip process, easy..
Professor Tae-Woo Lee's research team published in Advanced Materials Professor Tae-Woo Lee’s research team has developed technology for the high speed printing of microminiature and high integrated device electrodes that will work smoothly and efficiently in portable electronic devices. The research team, which consists of professor Tae-Woo Lee and doctoral student Yeongjun Lee of the Materials Science & Engineering department at POSTECH, published their findings in the Advanced Materials journal. Photolithography and electron-beam lithography are methods that are used to man..
Professor Doghoon Hyeon (Department of Mathematics) will receive the best paper award given by the Korean Mathematical Society (KMS) with Professor Sung Yeon Kim (Kangwon National University).KMS announced that they will have a Spring 2014 meeting for reading research papers fromApril24 to 26 at Gangneung-Wonju National University where Professor Hyeon will receive his award for best paper.Professor Hyeon published his paper inAnnals of Mathematics, a journal published by Princeton University, in 2013. His paper titled, “Log minimal model program for the moduli space curves: The first fl..
The research team of Professors Jaesung Park (Department of Mechanical Engineering) and Yong Song Gho (Department of Life Sciences) has developed a way to generate artificial nanovesicles that can be used to deliver RNA, a breakthrough that is expected to be used in exosomes research and to have applications in drug and RNA-delivery systems. Their paper, "Microfluidicfabrication of cell-derived nanovesicles as endogenous RNA carriers”,made it onto the cover of the journalLab on a Chipand was selected as a Hot Article. Exosomes/microvesicles are known to shuttle biological signals..
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..
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..
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..
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..
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..
