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..
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..
A research team, led by Department of Materials Science and Engineering Associate Professor Sei Kwang Hahn and graduate student Hwiwon Lee, has published research on a new rheumatoid arthritis treatment. The article “Hyaluronate – Gold Nanoparticle/Tocilizumab Complex for the Treatment of Rheumatoid Arthritis” was published in the April 2014 edition of the ACS Nano, a monthly scientific journal published by the American Chemical Society. Rheumatoid arthritis (RA) is a chronic inflammatory immune disease that affects 0.5 to 1 percent of the adult population worldwide and ..
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..
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..
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..
