Ten Breakthroughs of the Year 2011 by Science
Porous Zeolite Crytals Science, an internationally renowned scientific journal based in the US, has recently released a special issue of “Breakthrough of the Year, 2011,” dated December 23, 2011. In the issue, the journal introduces ten most important research breakthroughs made this year, and Professor Ryong Ryoo, Department of Chemistry at KAIST, was one of the scientists behind such notable advancements in 2011. Professor Ryoo has been highly regarded internationally for his research on the development of synthetic version of zeolites, a family of porous minerals that is widely used for products such as laundry detergents, cat litters, etc. Below is the article from Science, stating the zeolite research: For Science’s “Breakthrough of the Year, 2011”, please go to: http://www.sciencemag.org/site/special/btoy2011/ [Excerpt from the December 23, 2011 Issue of Science] Industrial Molecules, Tailor-Made If you ever doubt that chemistry is still a creative endeavor, just look at zeolites. This family of porous minerals was first discovered in 1756. They"re formed from different arrangements of aluminum, silicon, and oxygen atoms that crystallize into holey structures pocked with a perfect arrangement of pores. Over the past 250 years, 40 natural zeolites have been discovered, and chemists have chipped in roughly 150 more synthetic versions.

This year, researchers found new ways to tailor the size of their pores and create thinner, cheaper membranes. CREDIT: K. VAROON ET AL., SCIENCE334, 6052 (7 OCTOBER 2001) This abundance isn"t just for show. Three million tons of zeolites are produced every year for use in laundry detergents, cat litter, and many other products. But zeolites really strut their stuff in two uses: as catalysts and molecular sieves. Oil refineries use zeolite catalysts to break down long hydrocarbon chains in oil into the shorter, volatile hydrocarbons in gasoline. And the minerals" small, regularly arranged pores make them ideal filters for purifying everything from the air on spaceships to the contaminated water around the nuclear reactors destroyed earlier this year in Fukushima, Japan. Zeolites have their limitations, though. Their pores are almost universally tiny, making it tough to use them as catalysts for large molecules. And they"re difficult to form into ultrathin membranes, which researchers would like to do to enable cheaper separations. But progress by numerous teams on zeolite synthesis this year gave this “mature” area of chemistry new life. Researchers in South Korea crafted a family of zeolites in which the usual network of small pores is surrounded by walls holed with larger voids. That combination of large and small pores should lead to catalysts for numerous large organic molecules. Labs in Spain and China produced related large- and small-pore zeolites by using a combination of inorganic and organic materials to guide the structures as they formed. Meanwhile, researchers in France and Germany discovered that, by carefully controlling growth conditions, they could form a large-pore zeolite without the need for the expensive organic compounds typically used to guide their architecture as they grow. The advance opens the way for cheaper catalysts. In yet another lab, researchers in Minnesota came up with a new route for making ultrathin zeolite membranes, which are likely to be useful as a wide variety of chemically selective filters. This surge of molecular wizardry provides a vivid reminder that the creativity of chemists keeps their field ever young. Related References and Web Sites

Honorary Doctorate Presented to President of the Royal Swedish Academy of Sciences
KAIST presented to Dr. Svante Lindqvist, President of the Royal Swedish Academy of Sciences and Marshal of the Realm to the Swedish Royal Court, an honorary doctorate in science and technology on the 21st of November at Fusion Hall, KI Building. Dr. Lindqvist, a pioneer in the field of history of science and technology, showed how science and technology have affected the development of human civilization. His work in explaining the relationship between science and history made it easier to the public to understand the importance of science in our society, upon which he was conferred the honorary doctorate. Director Lindqvist obtained a doctorate from the Uppsala University of Sweden in 1984 with the dissertation, “Introduction of Steam Locomotive in 18th century Sweden.” This single dissertation won him three awards, which has been regarded even today as an introductory reading text to readers in the field of science history. Dr. Lindqvist established the Department of History of Science and Technology in Sweden Royal Institute of Technology in 1989 and was the department chair for nine years until 1997. He then became the founding director of the Nobel Museum from 1998 to 2009 and developed the museum from a mere display venue of Nobel’s legacy to a multifunctional research oriented institute that supports and holds various outreach activities such as seminars and public lectures. From the visit of Dr. Lindqvist to KAIST, students had a wonderful opportunity to engage with an internationally renowned scholar and, once more, to remind the university"s vision and mission, whereby they make contributions to the development of science, and ultimately, to the advancement of humanity.

Fusion performing arts, called space musical, 'NARO' performed at KAIST
In commemoration of the 6th anniversary of the establishment of the Graduate School of Cultural Technology, KAIST organized an English musical show on space at the Auditorium on the 29th and 30th of September. The name of the musical was NARO. The musical was funded by the ‘NaDa Center’ operated by KAIST’s Graduate School of Cultural Technology. The musical was created with participation from adolescents, which told a tale about a genius boy Naro’s journey in space. The musical was composed of two parts, and the basic storyline was about Naro who conducts research based on space, and his friends went on a time travel to the constellation Scorpios; more specifically, it was a Korean traditional children’s story about a brother and sister who became the sun and the moon. Naro and his friends prevent the plot of Tyran, a villan, who plans on destroying the space and Earth by inducing a red giant star, Antares. In preparation for the musical, NaDa Center selected 14 students ranging from elementary to high school students during March of 2011. The selected students met every Saturday and Sunday from March to September for practice; a gargantuan commitment. The theme of the musical is space, the future, and hope, and it does not utilize any stage settings. Instead, it attempts the incorporation of high technology into the stage by using interactive video, laser art, and specially built props. In addition, the entire process from script to performance and advertisement was utilized as an education model to suggest a good fusion between science and technology and cultural arts. The musical ‘NARO’ is a collective effort. Professor Won Kwan Yeon who pioneered the field of Cultural Technology directed the musical, Professor Koo Bon Chul was in charge of the script and music composition, acting was charged to Lee Min Ho, choreography was charged to Han Eun Kyung, astrological reference was charged to Park Seok Jae among other students in the Graduate School of Cultural Technology. Members of the KAIST Acting Club ‘Lee Bak Teo’, Jeong Soo Han, Son Sharon and graduate of Chung Nam National University with vocal music major Yang Su Ji also made appearances. The Space Musical ‘NARO’ was funded by the Korea Astronomy and Space Science Institute, Korea Aerospace Research Institute, and LG School of Multi Culture.

Review of organophosphonate nerve agent remediation and sensing chemistry
Professor David Churchill, Dept. of Chemistry, KAIST Scientists in Daejeon, South Korea and Lexington, Kentucky (USA) have recently published a review on the subject of nerve agent remediation and probing chemistry (Chemical Reviews, DOI:10.1021/cr100193y). This article endeavored to pursue organophosphonate nerve agent chemistry deeply and comprehensively and to reflect that decontamination / sensing and nerve agents / pesticides are quite inextricable: when one tries to degrade nerve agents one also needs to detect what components are still present “downstream,” etc. Nerve agents and many pesticides also share a common generalized organophosphate / -phosphonate structure. Also, the use of simulant molecules (mimics) and a consideration of the closely related organophosphonate pesticides were also treated comprehensively in the Review. The authors reached back into the literature when developing some sections to make important connections to the contemporary topics of interest. The review also includes industrial insights. Kibong Kim, Olga G. Tsay and David G. Churchill of the Department of Chemistry at KAIST and David A. Atwood of the Department of Chemistry of the University of Kentucky endeavored to "make a variety of connections in research strategies and (sub-) fields to present what is still possible, fruitful, practical, and necessary and to facilitate a current comprehensive molecular level understanding of organophosphonate degradation and sensing," Churchill says. The authors feel that for the time being, researchers in varying research areas “can use this manuscript effectively when considering future research directions.”

Scientists develop highly efficient industrial catalyst
http://english.yonhapnews.co.kr/business/2011/07/14/48/0501000000AEN20110714009600320F.HTML SEOUL, July 15 (Yonhap) -- South Korean scientists said Friday that they have developed a highly efficient nanoporous industrial catalyst that can have a considerable impact on chemical and oil-refining sectors. The team of scientists led by Ryoo Ryong, a chemistry professor at the Korea Advanced Institute of Science and Technology (KAIST), said the solid zeolite compound developed in the laboratory has a reaction speed five to 10 times faster than that of conventional materials. Zeolite, which is made from silica and aluminium, is frequently used as an absorbent, water purifier and in nuclear reprocessing, although it is mainly employed in the chemical industry. The annual size of the zeolite market is estimated at US$2.5 billion with output using the material topping $30 billion. At present, 41 percent of all catalysts used in the chemical sector are nano-scale zeolite materials. The KAIST team said that because the new zeolite is made up of different sized pores, the material can be used as a catalyst when existing materials are unable to act as a changing agent. "Existing zeolites only have pores under 1 nanometer in diameter, but the new material has holes that range from 1 nanometer to 3.5 nanometers, which are all arranged in a regular honeycomb arrangement," Ryoo said. A nanometer is one-billionth of a meter. He said the ability to have both micro- and meso-sized pores is key to the faster reaction speed that is an integral part of raising efficiency. The South Korean researchers used a so-called surfactant process to make the different sizes of pores. The development is a breakthrough because researchers and companies such as Exxon Mobil Corp. have been trying to build zeolite with different sizes of pores for the past two decades without making serious headway. There are more than 200 different types of zeolites in the world. Ryoo, who received funding from the government, has requested intellectual property rights for the discovery, which has been published in the latest issue of Science magazine. He also developed another zeolite in the past that can transform methanol to gasoline up to 10 times more efficiently than existing catalysts. Exxon Mobil has expressed interest in the two zeolites made by Ryoo"s team. Undisclosed South Korean petrochemical companies have also made inquiries that may lead to commercial development in the future. "There are some technical issues to resolve, mainly related with mass production and stability," the scientist said. He said full-fledge production will be determined by how much companies are willing to spend on research to speed up development that can bring down overall production costs. The KAIST team said it took two years to make the new zeolite, which can be custom made to meet specific needs. (END)
