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 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..
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..
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 ..
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 ..
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..
Professor Doghoon Hyeon (Department of Mathematics) will receive the best paper award given by the Korean Mathematical Society (KMS) with Professor Sung Yeon Kim (Kangwon National University).KMS announced that they will have a Spring 2014 meeting for reading research papers fromApril24 to 26 at Gangneung-Wonju National University where Professor Hyeon will receive his award for best paper.Professor Hyeon published his paper inAnnals of Mathematics, a journal published by Princeton University, in 2013. His paper titled, “Log minimal model program for the moduli space curves: The first fl..
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 ..
Professor Sung H. Han (Department of Industrial and Management Engineering) is an authority in the field of ergonomics, an applied science that deals with the design of devices and systems in conjunction with the physical working conditions, capacities, and requirements of the user. Professor Han has conducted research on human-computer interaction,effectiveproduct design, and the evaluation of product and service experience to provide better value to users. He has played a vital role in the establishment of Asia’s first National Institute of Ergonomics and is the founder of ACED (Asian ..
Professor Dong-Woo Cho’s team at POSTECH is engaged in the development of novel tissue and organ printing technology that can bridge that gap that currently exists between the supply and demand of tissues and organs for patients suffering from tissue loss or organ failure. This novel tissue printing technology could lead to the regeneration of healthy functional tissues or organs for patients, thus, eliminating the need for tissue grafts and mechanical devices. The POSETCH team made up of Falguni Pati, Jinah Jang, and Dong-Heon Ha, recently published their findings in an article entitle..
