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..
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..
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..
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..
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,..
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..
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..
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 ..
Prof. Bruno C. De Cooman of the Graduate Institute of Ferrous Technology (GIFT) at POSTECH was appointed as a Distinguished Member and Fellow of the Association for Iron & Steel Technology (AIST). The AIST Distinguished Member and Fellow Award, established in 1975, is awarded to an AIST member who has made outstanding contributions to the iron and steel industry as well as to the activities of the association. 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..
