PIRO, the Pohang Institute for Intelligent Robotics located on the POSTECH campus, the first independent research institute for intelligent robotics in Korea, released information on PIRO-U3, a cleaning robot that functions underwater. Under supervision, the robot can be used in various places, such as industrial water tanks, reservoirs, riverbeds and also inshore area. It is noteworthy that PIRO-U3 was completed with domestic techniques only.Before PIRO-U3, sediments at the bottom of industrial water tanks were manually removed after draining all the water; the cleaning process of riverbeds o..
Electronic displays that can be rolled up like newspapers, televisions that can be hung on walls like calendars, or computers that can be put on like clothes are fascinating ideas still to be realized. But technology certainly has evolved in this direction. A research team led by Professor Chan Eon Park of POSTECH’s Chemical Engineering Department has come forth with a breakthrough with organic electronics. The team’s work focuses on a specific type of Organic Thin- Film Transistor (OTFT) called n-type organic semiconductors. The ‘n’ stands for negative, indicating the ..
Amicrofluidic chip that can diagnose the warning signs of stroke (or cerebrovascular accidents) with only one percent of one drop of blood or medical devices that may be able to treat something as tiny as blood cells were previously just subjects for science fiction. But a recent study done by a POSTECH-Michigan University (USA) research team broke open the possibility to turn such ideas into reality. The study was selected as the Featured Paper on the May 17th edition of Nature Nanotechnology Online, a respected journal in the field of nanoscience. Dr. Sanghyun Lee, postdoctoral researcher at..
In the D. J. Caruso film Eagle Eye (2008), a super-computer equipped with artificial intelligence controls the society by monitoring everything with CCTVs located all over the world. A recent development suggests that the movie may possibly become a reality; a surveillance camera that can judge a situation by itself and prevent terrorism or theft has been invented.A research team led by Professor Daejin Kim of the Department of Computer Science and Technology has developed a technology which automatically detects unattended items as well as burglaries in public places such as subway stations a..
The term ‘biomass’ may seem unfamiliar at first glance, but it is closely connected to the energy sources we use in daily life. In simple terms, it refers to an organic matter that contains renewable energy. When solar energy is absorbed by any plant, photosynthesis stores the energy in chemical form, and biomass can be extracted from the plant.One way of using this biomass is burning it to obtain heat, which can in turn be used to generate electricity, but it can also be converted to practical forms of energy, such as transportation fuels like ethanol and biodiesel or methane gas...
If you are suffering from cancer and need interferon therapy, or if you need human growth hormone for the treatment of short stature, you could not escape unpleasant repetitive injections. The former requires thrice-a-week injections and the latter needs daily injections. However, such frequent injections are no longer necessary, thanks to a new drug delivery device developed by a POSTECH research team.For long-term controlled delivery, protein drugs had been encapsulated within biodegradable polymers such as poly (lactic-co-glycolic acid), PLGA. Despite successful commercialization, however, ..
Arsenic is a very toxic substance most widely used for wood preservers because it is a strong killer of insects and bacteria. It is also being applied in the manufacture of agrichemicals such as pesticides, insecticides and herbicides; but its usage has been declining because of adverse effects on the environment.Due to its odorless and colorless character, and its capacity to become transferred easily, arsenic intake can occur accidentally by drinking allegedly “clean” water. The World Health Organization estimated that approximately 57 million people worldwide are drinking arseni..
Anisotropic Fatigue Behavior of Magnesium Alloys InvestigatedENVIRONMENTAL protection has surfaced as a major problem that the world needs to solve, and there is no doubt that car pollution takes up a large portion of it. Therefore, the need for eco-friendly cars or ‘Green cars’ with lower emissions and more fuel efficiency is has increased, which explains why the recent work on the related subject conducted by POSTECH and the Korea Research Institute of Standards Science (KRISS) is gaining significance. It has been reported that Professor Chong Soo Lee and Sung Hyuk Park, a Ph.D. ..
The Core Technology for Ultrafast Silicon Device THE core technology that enables the realization of the fastest, nearly massless electrons has been successfully devised by a research team led by Professor Han Woong Yeom, Director of the Center for Atomic Wires and Layers at POSTECH. This achievement may lead to a breakthrough in the development of a truly new technology for semi-conductor devices. Professor Yeom’s team successfully developed a core technology that will enhance the speed of a silicon device by several ten-folds through utilizing the interface, which is the boundary betwe..
A Newly Discovered Mechanism May Lead to Climate RegulationAteam of environmentalphotochemists led by Professor Wonyong Choi of POSTECH has succeeded in explaining how natural ice in Polar Regions can provide the ocean with bioavailable iron content, which ultimately contributes to the prevention of global warming. This achievement in research has gained substantial attention from the international community as it was introduced in several well-known publications in the field of science and technology such as the May 6th issue of Environmental Science & Technology, and the May 17th issue o..
