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 ..
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..
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 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 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..
Professor Hyun M. Jang of the Department of Material Science and Engineering and a research team led by Jung-Hoon Lee, advised by Prof. Jang, recently discovered that Samarium ferrite (SmFeO3) is a multiferroics exhibiting connection between the order parameters. The result from Prof. Jang’s experiment was posted on Physical Review Letters, an authoritative paper in the physics area.Since SmFeO3 consists of orthorhombic structure, it has been known as material without magnetization; however, Prof. Jang and his research team found it actually has electrical polarization without any electr..
