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..
POSTECH scientists develop breakthrough technique to easily optimize electrical properties of Polyaniline nanosheets to an unprecedented level in an environmental-friendly and inexpensive way. A piece of deep frozen ice and electronic gadgets may seem to have little connection (except that they are both ‘cool’ to have on you), but ice could now play a role in opening a new era in the electronic industry where conducting polymers, simply put plastics with electrical properties, are in great demand for practical applications. Chemists at Pohang University of Science and Technolo..
Toxic environmental contaminants are increasingly known to cause a number of severe health problems, in particular on fetuses, including heart failure, low cognitive ability, delayed development, and neurobehavioral disorders.A new research featured in the Environmental Science and Technology published by the American Chemical Society suggests that the fetus is more vulnerable to some pollutants with certain properties because they penetrate further into the feto-maternal system. The research found that distributions of pollutants and the mechanisms of distributions vary depending on each poll..
In new research published in Nature, Professors Nack J. Kim and Hansoo Kim and doctoral student Sang-Heon Kim at the Graduate Institute of Ferrous Technology (GIFT) at Pohang University of Science and Technology (POSTECH) have developed a new type of steel with improved tensile strength and lightness. There is a growing demand for lightweight structural materials as an alternative to conventional steels which are heavy and impractical in developing future energy efficient vehicles. Studies on lightweight steels have shed light on the effectiveness of aluminum alloying in increasing the streng..
POSTECH Professor Jong-Ram Lee (Dept. of Materials Science & Engineering) received the Inventor King of the Year Award (a Presidential Citation) from the Korean Intellectual Property Office (KIPO) at the 50th Anniversary Ceremony for Korea Invention Day on May 19th, 2015. Mr. Baekhee Lee, a Ph.D. student in the Dept. of Industrial Management & Engineering, also received the Minister of Science, ICT and Future Planning’s Citation at the ceremony. KIPO selected Prof. Jong-Ram Lee as the winner this year for his contribution to the commercialization of next-generation flexible ele..
Professor Kilwon Cho, Hyojin Bong, and Dr. Sae Byeok Jo of the Department of Chemical Engineeringhave developeda new synthetic method for high-throughput production of large-area conductinggraphenefilms. The research outcome was featured on the cover page of the renowned international journal Nanoscale. Grapheneis one of the core materials for the transparent electrodes in soft electronics due to its highelectricconductivity, flexibility, mechanical strength and transparency. The feasibility of the commercialization ofgraphenefilms depends on the efficient“scale-up” production of ..
Phytoplankton, commonly known as plant plankton that remove carbon dioxide from the atmosphere through photosynthesis, are potentially a key driver of Arctic warming under greenhouse warming, a study reveals. Scientists with Pohang University of Science and Technology (POSTECH), Max Planck Institute for Meteorology (MPI-M), and Korea Institute of Ocean Science and Technology (KIOST), presented on Monday, April 20, in Proceedings of National Academy of Sciences (PNAS) Online, the geophysical impact of phytoplankton that triggers positive feedbacks in the Arctic warming when the warming-induce..
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,..
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, 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 ..
