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..

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 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..
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..
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..
