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..
Revolutionary plastic memory devices developedRecent increases in demand for mobile devices have stimulated the development of nonvolatile memory devices with high performance. These nonvolatile memory devices are unpowered computer memory devices such as USB flash drives. However, with recent developments will soon see foldable electronic newspapers, books, magazines, and even wearable computers. Professor Moonhor Ree (Department of Chemistry) and Professor Ohyun Kim (Department of Electronic and Electrical Engineering) research team, in their paper entitled, “Novel Digital Nonvolatile ..
POSTECH celebrated its 20th Anniversary on December 3rd, 2006.On December 3rd, 1986 established as Korea’s first research-oriented science and technology university, POSTECH began its journey to become one of the world’s leading research-oriented universities.After a short history of only 12 years, POSTECH topped the list of Asia’s leading science and technology universities by Hong Kong based Asiaweek in 1998 and the Times Higher Education Supplement ranked POSTECH 25th (3rd in Asia) in citations per faculty.The main driving force of POSTECH’s rise to the top was the f..
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 ..
It is well known that plants can fix carbon dioxide (CO2) into sugar. In plant cells, the chloroplast is responsible for fixing carbon dioxide into sugar. Thus chloroplasts as the factory for sugar production play essential roles not only for plants themselves but also for most of living organisms on Earth. However, chloroplasts are not just carbon dioxide fixing factory but also responsible for producing a large number of chemical compounds that are essential for plant growth and development. Interestingly, chloroplasts in plant cells are thought to be originated from ancestral cyanobacterium..
Lord Rayleigh wrote about the two-dimensional whispering gallery mode (WGM) in 1910 after a visit to the dome of St. Paul’s cathedral in London. The whispering cave mode (WCM) is a threedimensional (3D) effect?a toroid with circular helix symmetry?which recent studies have shown can be used to create photonic-quantum-ring (PQR) lasers that emit in the blue-violet part of the spectrum. A research team at Pohang University of Science and Technology (POSTECH, Pohang, Korea) first created 3D WCM lasers that emit in the infrared and red part of the spectrum. To achieve this, professor O&rsquo..
POSTECH, joining hands with Dong-A University and Seoul Pharmaceutical Co., Ltd., hastens development of a novel sepsis medication materialized with domestic technology.POSTECH team of Professor Sung Ho Ryu and Professor Yoon-Keun Kim (Department of Life Science), in a joint research with Professor Yoe-Sik Bae of Dong-A University, supported by POSCO and Ministry for Health, Welfare and Family Affairs, has developed peptides that effectively prevent progression of sepsis.In animal experiments, the peptide ligands newly developed for formyl peptide receptor like-1 (FPRL1) in septic mice resulte..
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..
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..
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..
