Improvements in performance and reductions in cost of silicon-based nonvolatile memories, such as flash random access memory (flash-RAM), have rendered floppy discs and many other forms of portable storage obsolete. But for many uses that require data to be written only once, such as archiving and security applications, their cost effectiveness is limited. So-called write-onceread- many (WORM) memories made from low-cost polymer materials could provide a solution. The devices, developed by Professors Moonhor Ree, Ohyun Kim, Su-Moon Park and their research teams, are based on hyperbranched copp..

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..

Ultra-fast flash light revealing mystery of atoms, into the world of attoseconds (10-18 second)Beyond the femtosecond (10-15 second) barrierAs momentary flash lights capture the motion of fast moving objects such as a bullet or explosion splinter, ultra-fast laser lights can be utilized to take pictures of ultra-fast natural phenomena following their dynamical change. The last decade has observed a rapid progress in femtosecond laser technology. This development allows us to carry out new kinds of experiments to open up a new area of nature that has never been explored before. Is there no phen..

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 ..

As the eventful year of 2008 comes to a close and the New Year of 2009 begins, I wish all of you a New Year full of happiness and love.2009 is the Year of the Ox. There is an old saying that goes, “Ox pace takes you a thousand miles,” which means slow and steady steps take you much farther. This year’s start is cloudier and gloomier than ever. The recent global economic crisis has been even more brutal than the foreign exchange crisis we experienced a decade ago. At a time of such hardship, we should learn from the wisdom of the ox, not panicking or getting nervous, but being..

Honorable founding Chairman Tae-Joon Park, fellow Postechians, guests, ladies and gentlemen!We are gathered here today to commemorate the significant occasion of POSTECH’s 20th Anniversary.I would like to extend my deepest respects to the founding Chairman Tae-Joon Park for his dedication and resolution to establish a world-class research-oriented university despite overwhelming criticism and opposition 20 years ago and to POSTECH Foundation and POSCO for their absolute confidence and wholehearted support. Also, warm welcome is due to the many dedicated people who have contributed to mak..

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..
