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..

One of the most basic yet important surgical skills to keep a patient alive and intact may be closing wounds. It seems that doctors will now get the job done with more ease thanks to new, nontoxic surgical glue that instantly seals a bleeding wound and helps it heal without a scar or inflammation. Inspired by nature’s wonders, Korean scientists at Pohang University of Science and Technology (POSTECH) have developed a light-activated, mussel protein-based bioadhesive (LAMBA) that works on the same principles as mussels attaching to underwater surfaces and insects maintaining structural ..

M.S.-Ph.D. Integrated CourseStudent Jingoo Kim Wins the 2015 Dow Korea Award Professor Joon Won Park of the Dept. of Chemistry at POSTECH was selected as the winner of the Academic Excellence Prize by the Korean Chemical Society. The Korean Chemical Society presented the Academic Excellence Prize to him in recognition of his outstanding achievements in the field of chemistry and great contribution toward advancement of chemical technology. He delivered a commemorative lecture to celebrate his prize-winning at the 115th General Meeting of the Korean Chemical Society. After receiving his P..

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..

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..
