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..

When several electronic devices are linked through fixed and mobile connections, time-delays inevitably occur due to the limitation of data transmission speed; it is known that systems with these types of aftereffects often experience instability or performance degradation. Substantial research efforts have been made to tackle this problem and POSTECH researchers are reported to have provided an important foundation for the related literature. An article published by Dr. PooGyeon Park, a professor of the Department of Electrical Engineering at POSTECH, was selected as the most cited article in..
