Professor Sangmin Jeon (CE) and Jinmyoung Joo (Post Doc.) have developed the technology that diagnoses cancer by using micro-oscillators made of photo- catalytic silicon and nanoparticle on the inside and magnetic material on the outside. This technology, published on ACS Nano, attracted academic attention because it could be applied to cancer diagnosis at once as well as early detection, which is crucial in cancer treatment.When patients suffer from cancer, the concentration of specialized proteins in blood and other body fluids increases. This technology uses the concentration of the protein..
Professor Kijung Yong (CE) and his research team succeeded in developing a nonvolatile memory cell which is waterproof and maintains information without power supply. Nonvolatile memory cells could be used in production of waterproof computers and smart phones by using nanotechnology.Memory cells currently used are vulnerable to water. To solve this problem, the research team synthesized the tungsten oxide semiconductor using natural effects called the Lotus Effect, an imitation of lotus leaves, which could wash the dust off the surface without wetting it. In addition, they developed resistive..
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..
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..
The research team of Professor Hyung Joon Cha (CE), Prof. Dong-Woo Cho (ME), and Prof. Rhie, Jong Won (The Catholic University of Korea) succeeded in developing functional three-dimensional scaffolds that enhance regeneration of bone tissue. Using mussel adhesive proteins, it is safe for the human body. It is also proven to be remarkable in adhesion and coating. This research was published in the Apr. 2 online version of Acta Biomaterialia, a renowned academic journal in the field of body materials.The research team affixed the stem cell on the surface of the polymer using the mussel-extracted..
POSETCH researchers have successfully developed the particle beam technique to eliminate nanometer-sized contaminant particles (CPs) of nano-scale devices, for the first time in the world.A research team led by Professor Jin Won Lee of the Department of Mechanical Engineering has succeeded in developing the technology to completely remove 10 nm-sized CPs using a revolutionary beam technique that uses nanometer-sized bullet particles (BPs) moving at supersonic speed. The research result has been published in the online edition of Nanoscale Research Letters on Apr. 11.Due to the attraction by su..
When we pour a carbonated drink into a cup, we see small droplets popping over the surface. This happens because air bubbles float up in water and burst on the water surface, ejecting water particles into the air. These water particles are called ‘aerosols.’ In general, aerosols are tiny particles whose size ranges from a few nanometers to several micrometers that freely float in the atmosphere. Water droplets, dust, smoke, and water haze are typical examples of aerosols. They may either act as cloud condensation nuclei stimulating cloud formation, or scatter and absorb solar light..
Solar cells are converters that make electricity out of light energy by the photovoltaic effect. Made with organic semiconductors, organic solar cells are light and flexible, can produce electricity with a small amount of sunlight, and can be manufactured at a low cost. As a result, they are suitable for products that need self-generated electricity such as solar windows or certain military products rather than for solar power plants. In Angewandte Chemie, a renowned journal for the field of chemistry, a POSTECH master’s student published a paper on a new manufacturing technology for org..
Asmart nanomedicine customized for liver diseases has been developed by Professor Sei Kwang Hahn’s research team in the Department of Materials Science and Engineering. Hyaluronic acid is a bio-polymer of high biocompatibility and stability, and can be target-specifically delivered to liver tissues. Capitalizing on this characteristic of hyaluronic acid, Prof. Hahn built a liver-targeted drug delivery system, which is expected not only to reduce serious side-effects of the conventional uncustomized medications, but also to advance the effectiveness of the drug for hepatitis, liver cirrho..
Water probably is the greatest enemy for most electrical devices; water short-circuits electric devices. Therefore the demand is high for developing water-resistant components, and in particular, those to be used for expensive, high-performance electronic devices. Professor Kijung Yong of Department of Chemical Engineering and PhD candidate Seunghyup Lee have utilized the ‘lotus leaf effect’ with nano materials and manufactured an electronic device that shows stable performance even when soaked in water. The result was published online in Advanced Materials, a renowned journal in m..
