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..

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..

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 ..

POSTECH researchers have found another reason to cut down on a high-fat and cholesterol diet. Their findings show that cholesterol is crucial for Wnt signaling pathway often linked to human birth defects, cancer, and other diseases. Research groups of Prof. Jin-Kwan Han in the Department of Life Sciences at POSTECH and Prof. Wonhwa Cho from the University of Illinois at Chicago performed this study. Their research was published in the July edition of Nature Communications. Wnt signaling processes biological functions through ‘canonical’ and ‘non-canonical’ pathways..

A research team comprised of Professor Taiho Park, Jongchul Lim, and Taewan Kim of the Department of Chemical Engineering, reported a novel way to solve both dye regeneration and electron transport problems simultaneously using a “ladder” concept. The paper was published in the December issue of Energy & Environmental Science. Next generation energy devices should be based on clean and sustainable solar energy. Among the conventional solar energy device, dye-sensitized solar cells (DSCs) have lots of advantages with higher power conversion efficiency such as chip process, easy..

Professor Tae-Woo Lee's research team published in Advanced Materials Professor Tae-Woo Lee’s research team has developed technology for the high speed printing of microminiature and high integrated device electrodes that will work smoothly and efficiently in portable electronic devices. The research team, which consists of professor Tae-Woo Lee and doctoral student Yeongjun Lee of the Materials Science & Engineering department at POSTECH, published their findings in the Advanced Materials journal. Photolithography and electron-beam lithography are methods that are used to man..

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..

POSTECH Department of Chemical Engineering Professor Hyung Joon Cha and his team’s research on bone graft material binder technology was published in the Journal of Materials Chemistry B.Mussels stick to rocks because its protein has strong adhesive properties. This protein has been used as a binder for bodily wounds and surgery. An engineered mussel glue protein,a promising functional binder for the acceleration of bone substitute-assisted bone regeneration,has been developed by the joint research team of POSTECH and Korea University Anam Hospital, which can be used in teeth implants. ..

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 Sei Kwang Hahn and co-workers in the Department of Materials Science and Engineering at POSTECH, and Professor Allan S. Hoffman at the University of Washington, have investigated various kinds of hydrogels developed for stem cell therapy as a regenerative medicine. Their work is published in the latest edition of Progress in Polymer Science (IF = 26.854), an international peer-reviewed scientific journal in the field of polymer science and engineering. The paper entitled “In situ-forming injectable hydrogels for regenerative medicine” describes advanced polymeric hydrogel..
