Lesson from Lotus Leaf:Photoreversibly Switchable Smart Surface

Professor Kilwon Cho and Doctor Ho Sun Lim of the Department of Chemical Engineering discovered the smart surface that can switch reversibly from extreme water-hating (superhydrophobic) to dramatic water-loving (superhydrophilic) via exposure to ultraviolet or visible light (J. Am. Chem. Soc., 2006, 128, 14458). Recently, this smart surface was introduced with the subject, “Self-Cleaning Materials: Lotus Leaf-Inspired Nanotechnology” in a hot issue of materials science field in Scientific American. The lotus grows in muddy water, but its leaves, when they emerge, are seemingly neve..

Hybrid Nanostructure Fabrication Using an AAO Nanotemplate and Highly Conformal ALD

Nowadays the term of ‘nano’, which means 10-9 as the SI prefix, is commonly mentioned in the media. Usually, a human hair is taken as a means for lifelike recognition of 1 nanometer. One nanometer is 1/100,000 of a hair, which is too small to observe through optical microscope. When we consider that 1 nm is 3 or 4 atomic scale at the most, similar to DNA with the size of 2 nm, its very small size is true to nature for us. Hence, to control an individual atom and to reveal the mystery of the DNA of human body, ‘nanotechnology’ has been attracting great attention as one o..

p-aminobenzoate N-oxygenase:Novel Enzyme Chemistry for Antibiotics Biosynthesis

Many clinically important drugs are natural products produced by bacteria and fungi. In particular, polyketide antibiotics have been found to be an extremely rich source of biologically active compounds with a broad range of pharmaceutical activities. Aromatic nitro groups are relatively rare functional groups in natural products including polyketide antibiotics but are found in diverse types of important antibiotics, such as chloramphenicol, pyrrolnitrin, aureothin, azomycin, and rufomycin. Surprisingly, the biosynthesis of aromatic nitro groups is poorly understood. To date, only two enzymes..

Microcantilevers with Nanochannels

The invention of the scanning tunnel microscope (STM) opened the door to nanoworld, enabling humankind to actually touch and feel the individual atoms at the surface of a material. It has inspired a series of inventions such as the atomic force microscope (AFM), the lateral force microscope (LFM), the magnetic force microscope (MFM), etc. Recently, the scanning probe microscope (SPM), which encompasses all these inventions, has evolved into the millipede technology which has a potential to make competing data storage technologies obsolete. A common denominator of these exciting developments is..

Novel Programmable &#38quot;Write-Read-Erase&#38quot; Non-Volatile Polymer Memory Device Operative Even in Spa..

As technology continues to get smaller, and as memory needs become more demanding, the microelectronics industry requires devices that are more cost-efficient and lightweight. And, while organic memory materials have shown some promise on improvement in performance and reductions in cost, they still lack some of the essential qualities, such as durable performance even in a harsh condition, needed for application in a wide variety of fields. So-called Non-Volatile Memories (NVM) from thermally and dimensionally stable polymer materials could provide a solution.The devices, developed by Profess..

Regulation of Stomatal Response to Elevated CO2 Concentration by AtABCB14

Climate change caused by increasing atmospheric CO2 is a major environmental problem of the 21st century. There has been much discussion about how to reduce CO2 output and prevent global warming. In this respect, plants are an important part of the overall picture as they are primary CO2 consumers and are directly challenged by increasing CO2 levels. Moreover, plants vary in their responses to elevated CO2. Plants that adapt better to this change are expected to out-compete their neighbors, which would cause instability in present ecosystems and unpredictable changes in weather and climate.In ..

Structure and Mechanism of MukBEF Condensin Deciphered

A research team of Department of Life Science’s Center for Biomolecular Recognition and Division of Molecular and Life Science, consisting of Professor Byung-Ha Oh, Doctor Jae-Sung Woo, and Doctor Jae-Hong Lim, has solved secrets of the ring-shaped molecular structure of the MukBEF condensin, the key mediator of chromosome condensation.In eukaryotic organisms, chromosomes are found in the nucleus of every cell. Before cell division, chromosomes are condensed, and the two replicated copies of the chromosomes are partitioned into the two daughter cells. In prokaryotic organisms, chromosome..

Wonders of nature

Practical recombinant hybrid mussel bioadhesiveWhat man-made good exists that provides us both life’s necessity and luxury? A popular seafood cuisine, mussels are enjoyed all around the world. They can be smoked, boiled, or steamed to be served alone or as an ingredient of a larger dish. It can also produce beautiful pearls and jewelry. Now scientists have discovered another use for this nature’s gift. Professor Hyung Joon Cha and his team at the Department of Chemical Engineering have developed a novel type of practical recombinant hybrid bioadhesive material that originates from ..
