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..
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..

Morlock Award given by the Institute of Electrical and Electronics Engineers (IEEE) Engineering in Medicine and Biology Society, the university said Tuesday.Established in 1960 by the family of William J. Morlock, the award is given semi-annually to people who have made innovative applications of electronic techniques and concepts to solve biomedical problems.Kim was recognized with his ..
As it is better to wear clothes that fit you well rather than to try on many possible sizes, it is also most prudent to take pills that cure your ailments precisely without triggering unwanted side-effects. A POSTECH joint research team has contributed to the forthcoming era of customized medicines by developing a very precise way to detect the genetic variations among individuals. The team has made it possible to prescribe appropriate therapeutic administrations for each individual. This new technology can assign the most appropriate pills for a cold, anticipate the effects of new anti-cancer..
