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..
Professor Sung-Mo Jung of Graduate Institute of Ferrous Technology received the Adrian Normanton Award from the Institute of Materials, Minerals and Mining (IOM3). Newly established last year in recognition of the late Dr. Adrian Normanton, a renowned UK steel engineer, the award is given for the best technical paper on the topic of steelmaking or casting presented in Ironmaking & Steelmaking: Processes, Products and Applications published by IMO3. Professor Jung was named the Adrian Normanton Award winner for 2015 for his paper on the effect of surface roughness of MgO substrate on th..
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..
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 ..
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..
Despite having numerous advantages, clinical applications of 3D printed scaffolds for tissue regeneration are extremely rare. A team consisting of POSTECH Professor of Mechanical Engineering Dong-Woo Cho, Professor Jong Won Rhie of the Department of Plastic Surgery College of Medicine at the Catholic University of Korea, and Won-Soo Yun of T&R Biofab Co., have applied 3D printing technology for correcting an asymmetric face caused by the removal of a tumor in a patient about a decade ago.The patient had trauma in the right malar region and because of this his eyes were misaligned. In this ..
The fundamental concepts of physics are crucial to understanding the correlation of the structure and strength of materials. Some materials, like a steel coil spring or rubber, are elastic. Grasping a rubber ball deforms the shape momentarily before it returns to its original state. Other materials when manipulated with, such as clay, will retain its newly deformed shape. This phenomenon, called plasticity, has been studied by scientists in designing high strength steels and alloys. The demand for high-technology metallic materials continues to depend on further research and understanding of ..
Using POSTECH Professor Chulhong Kim’s custom-built high-resolution photoacoustic imager, researchers were able to examine the combination of nanonaps and photoacoustic tomography illuminated inside the intestine of a mouse. (Credit: Chulhong Kim) Millions of people worldwide who suffer from digestive diseases may soon have a safer alternative to traditional radiological techniques when visiting the hospital for imaging of the gastrointestinal tract. Researchers from the Pohang University of Science and Technology (POSTECH), the University at Buffalo, and University of Wisconsin&ndas..
