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 ..
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..
A research team consisting of Dr. Gil-Ho Lee, Prof. Hu-Jong Lee, Sol Kim, and Prof. Seung-Hoon Jhi of Department of Physics, reported realization of “short and ballistic” Josephson junctions based on a monolayer graphene sheet. The paper was published in the February issue of Nature Communications. Josephson junction, a nanometer-scale hybrid superconducting device, consists of two superconducting (S) electrodes weakly coupled by a normal-conducting (N) insert. It supports a resistance-free junction supercurrent along with quantum interference effects and has been utilized for rea..
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..

Prof. De Cooman is the first scholar from a Korean research institution in the last 20 years to be named an AIST Distinguished Member and Fellow. Prof. De Cooman started his acade..
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 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,..
