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..

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..

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..

Atransparent and flexible organic transistor was recently developed by a POSTECH-SKKU joint research team. Professors Kilwon Cho and Kwang Soo Kim teamed up with Professor Byung Hee Hong at Sungkyunkwan University and worked on graphene, the ‘dream material,’ stepping into the market of next generation displays such as transparent monitors, windows, and flexible displays that can function like GPS navigation systems on automobiles and wearable electronic devices. The research team used graphene as electrodes for Organic Thin-Film Transistors (OTFTs) and successfully produced a flex..

It is not uncommon for diseases such as diabetes, hypertension and cancer to develop complications. Recently, a research team led by Professor Sanguk Kim of Department of Life Science successfully devised a method for predicting disease complications based on comorbid disease pairs by employing a network medicine approach. Jointly with Professor Sung Ki Jang of Life Science, PhD candidate Solip Park, and Professor Juyong Park of Kyung Hee University, Professor Kim published a paper, ‘Protein localization as a principal feature of the etiology and comorbidity of genetic diseases’ in..

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..
