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..
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. ..
Noise plays a key role in important biological processes, such as bacterial antibiotics resistance, cancer development, and stem cell differentiation. Physics can explain much of this biological phenomenon. Professor Nam Ki Lee of the Department of Physics and the School of Interdisciplinary Bioscience and Bioengineering with Department of Physics graduate students Sora Yang, Seunghyeon Kim, Cheolhee Kim, Hyeong Jeon An and Professor Jaeyoung Sung of Chung-Ang University studied how cells propagate noise using RNA polymerase. Their research was published in this month’s Nature Communica..
Professor Yoon-Seok Chang (School of Environmental Science and Engineering), a worldwide authority on dioxin, has been selected as a first prize winner of the academic research award by the Korean Society of Environmental Engineers. An awards ceremony was held at the Kimdaejung Convention Center on August 21st. Over the past 30 years, Professor Chang has published nearly 200 SCI papers and studies which include analyses of toxic substances such as dioxins and other endocrine on human health. His study of the environmental risks of bio-nanomaterials has recently received academic attention.
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 ..
Professor Suk Bong Hong(CE and School of Environmental Science and Engineering) and Hyung Ki Min(CE, Ph.D. candidate) succeeded in converting meta-xylene to para-xylene using zeolite catalyst based on gas chromatography-mass spectrometry-computer(GC-MS-CPU) and isotope exchange method. Para-xylene which is used to make polyester fibers, plastic bottles, and films is a basic petrochemical material made through isomerization of meta-xylene, whose mechanism has been merely a hypothesis. Unlike other technologies, this technology can now be realized ex hypothesi.The research team is receiving atte..
A research te-am that consists of Professor Tae-Woo Lee (MSE), Tae-Hee Han (MSE Ph.D. ca-ndidate), Prof. Jong-Hyun Ahn (SKKU), and Prof. Byung Hee Hong (SNU) has developed graphene into organic light-emitting diode (OLED) and flexible, white light with it for the first time.This team noticed that the inefficiency of graphene in OLED can be resolved by replacing conventional indium tin oxide anodes with high-work-function, low-sheet-resistance graphene anodes. The team improved the luminous efficiencies to 37.2 Im/W for fluorescent and 102.7 Im/W for phosphorescent devices, which are higher tha..
Baekhee Lee (IME Ph.D. candidate) and Jihyoung Lee (IME M.S. candidate) of the Ergonomic Design Technology Lab (advisor Professor Heecheon You) invented the “PC based glaucoma detector,” which can be easily installed on a PC to test one’s sight and development of glaucoma.The detachable, newly developed equipment effectively induces eye movements and allows for a self-vision test. The result is further used to analyze the progress of optic nerve damage, therefore the diagnosis of glaucoma.Glaucoma is an eye disorder in which the optic nerve is damaged, permanently impairing v..
