A research team comprised of Prof. Dong Sung Kim and Sang Min Park from the Department of Mechanical Engineering has developed a novel fabrication technique, called electrolyte-assisted electrospinning (ELES), for a self-assembled, free-standing nanofiber membrane. The research outcome was featured on the Inside Cover of the renowned international journal Advanced Materials.Nanofiber membranes have attracted substantial interests in recent years due to their large surface area, high surface to volume ratio, and porosity. These advantages have expanded their applications to sensors, filtration,..
A team comprised of Profs. Chulhong Kim and Geunbae Lim, Jin Young Kim, Changho Lee, and Kyungjin Park, developed a high-speed optical-resolution photoacoustic microscopy (OR-PAM) system using 2-axis waterproofing MEMS scanner, successfully monitored the flow of carbon particles in-vitro, and imaged microvascular networks of the mouse ear in vivo. Their research findings were published in Scientific Reports journal. Photoacoustic imaging technique is a hybrid biomedical imaging technique that combines the merits of ultrasonic and optical imaging modalities. When a pulsed light illuminates and..
A research team consisting of Prof. Joon Hak Oh, Moo Yeol Lee (Department of Chemical Engineering, POSTECH), and Prof. Bumjoon J. Kim (Department of Chemical and Biomolecular Engineering, KAIST) has developed highly sensitive and selective liquid-phase sensors based on a solvent-resistant organic semiconducting layer. The research outcome was highlighted as the cover article in Advanced Materials which is a renowned international journal in the field of materials.Sensors based on organic field-effect transistor (OFET) platform have attracted great interest due to their use as light-weight, low..
A research team, led by Department of Materials Science and Engineering Associate Professor Sei Kwang Hahn and graduate student Hwiwon Lee, has published research on a new rheumatoid arthritis treatment. The article “Hyaluronate – Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis” was published in the April 2014 edition of the ACS Nano, a monthly scientific journal published by the American Chemical Society. Rheumatoid arthritis (RA) is a chronic inflammatory immune disease that affects 0.5 to 1 percent of the adult population worldwide and ..
Professor Dong-Woo Cho’s team at POSTECH is engaged in the development of novel tissue and organ printing technology that can bridge that gap that currently exists between the supply and demand of tissues and organs for patients suffering from tissue loss or organ failure. This novel tissue printing technology could lead to the regeneration of healthy functional tissues or organs for patients, thus, eliminating the need for tissue grafts and mechanical devices. The POSETCH team made up of Falguni Pati, Jinah Jang, and Dong-Heon Ha, recently published their findings in an article entitle..
Using POSTECH Professor Chulhong Kim’s custom-built high-resolution photoacoustic imager, researchers were able to examine the combination of nanonaps and photoacoustic tomography illuminated inside the intestine of a mouse. (Credit: Chulhong Kim) Millions of people worldwide who suffer from digestive diseases may soon have a safer alternative to traditional radiological techniques when visiting the hospital for imaging of the gastrointestinal tract. Researchers from the Pohang University of Science and Technology (POSTECH), the University at Buffalo, and University of Wisconsin&ndas..
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..
