Professor Kijung Yong (Department of Chemical Engineering) and his group have succeeded in developing an original technology utilizing the lotus effect, which may be used toward development of a variety of applications using coated surfaces.Leaves of the lotus flower have very high water repellency due to the complex, nanoscopic structure of their surface. Superhydrophobic nanostructured surfaces, such as the lotus leaf, have shown potential for a variety of applications, including microfluidics in biotechnology, fog-resistant coatings, impermeable textiles, anti-contamination, and self-cleani..
Despite its potential risks, general anesthesia and how it leads human brain to unconsciousness is still not known. A POSTECH research group has been investigating the nature of consciousness as well as control of the level of consciousness through anesthesia, whose effort has drawn much attention of the academia.Professor Seunghwan Kim (Department of Physics) and his team, in a joint study with POSTECH graduate Doctor UnCheol Lee of University of Michigan and a Seoul Asan Medical Center team, have presented evidence that the transition from consciousness to unconsciousness occurs by the suppr..
Many studies have addressed the effect of sugar in the diet on obesity and diabetes. Professor Seung-Jae Lee (Division of IT Convergence Engineering, Department of Life Science, School of Interdisciplinary Bioscience and Bioengineering) and his group report that it might also be taking years off the life span.Professor Lee’s group, in collaboration with Professor Cynthia Kenyon of the University of California, San Francisco, discovered that glucose inhibits the activities of the glycerol channel in C. elegans, shortening the life span of the worm by about 20 percent. The group traces the..

Some universities require that even the departments of Korean literature and Korean history offer courses taught in English. Some professors are in favor of these "globalizing" changes, while others are doubtful.Amid the controversy, Pohang University of Science and Technology or POSTECH recently announced that it will transform into an English-only zone withi..

Professor Taihyun Chang (Department of Chemistry) and his group have developed toroidal micelles of uniform size from diblock copolymers.Block copoloymers can spontaneously self-assemble in a selective solvent to form micelles of various morphologies such as spherical micelles, cylindrical micelles, and vesicles. Recently, the variety of micellar shapes have been expanded to unconventional forms including toroids, tubes, disks, helices, and other complex forms.Although the toroid-shaped micelles have been reported earlier, the applicability of the toroid structure had been low due to the diffi..
Professor Moon-Ho Jo (Department of Materials Science and Engineering) and his group, in a joint study with a Harvard University team, have materialized a new all-electrical surface plasmon polaritons (SPPs) detection technique based on the near-field coupling between guided plasmons and a nanowire field-effect transistor. Photonic circuits can be much faster than their electronic counterparts, but it is difficult to miniaturize them below the optical wavelength scale. Nanoscale photonic circuits based on SPPs are a promising solution to this problem because they can localize light below the d..
A team of multinational scientists developed a technique to produce tiny, nano-sized optical lenses, a breakthrough that may open new possibilities in microscopy and bio-imaging, the researchers said Wednesday. In a study published in peer-review journal Nature, the researchers, led by Kwang Kim, a researcher from the Pohang University of Science and Technology (POSTECH), said they found that cup-shaped organic molecules, called calyx hydroquinone (CHQ), self-assemble into a lens shape when placed on a surface. The nano-lenses produced in this way could push lens-based magnification to resolve..
Professor Suk Bong Hong (School of Environmental Science and Engineering) and his research group have discovered that PST-1 (POSTECH number 1), the newly named synthetic small-pore zeolite molecular structure, selectively adsorbs hydrogen.The zeolites’ ability to discriminate between molecules of different sizes and shapes has long been recognized. However, examples of selective adsorption of the smallest gases in zeolites are scarce.PST-1, the synthetic small-pore zeolite with the natrolite topology and a potassium gallosilicate composition, was discovered to adsorb only the smallest ga..
