Thomson Reuters Nominates Distinguished Professor Ryong Ryoo for Its 2014 Nobel Citation Laureates in Chemistry
The Intellectual Property & Science business of Thomson Reuters announced on September 25th its “2014 Citation Laureates,” a list of candidates considered likely to win the Nobel Prize in the fields of physics, chemistry, physiology or medicine, and economics. The annual Thomson Reuters Citation Laureates will be recognized in perpetuity as contenders for a Nobel Prize.
Distinguished Professor Ryong Ryoo of the Department of Chemistry, KAIST, has been nominated for the 2014 Thomson Reuters Citation Laureates in Chemistry. He is the first Korean scientist who has made the list. In addition to Professor Ryoo, seven other scientists were selected as possible contenders for the 2014 Nobel Prize in Chemistry, or in the future.
Professor Ryoo was named alongside Charles T. Kresge, Chief Technology Officer of Saudi Aramco, Dhahran, and Galen D. Stucky, Professor of the Department Chemistry and Biochemistry at the University of California, Santa Barbara, for their research on the design of functional mesoporous materials (http://sciencewatch.com/nobel/2014-predictions/chemistry-laureates). Mesoporous materials have high surface areas with narrow pore-sized distribution and tunable pores diameters, offering promising properties and applications in various areas including adsorption, separation, sensing, and catalysis.
Professor Ryoo has focused his research interest in the synthesis of new functional nanoporous materials such as hierarchical zeolites, mesoporous silicas, carbons, and organic-inorganic composite materials that can be used for advanced applications in the production of alternative energy sources and in green chemical processes.
According to the press release by the Thomson Reuters, the list of the 2014 Nobel predictions includes 27 researchers representing 27 distinct academic and research organizations across nine different countries.
The annual Thomson Reuters Citation Laureates study is based on the analysis of proprietary data from the research and citation database, identifying the most influential researchers in the categories of chemistry, physics, physiology or medicine, and economics. Since its inception in 2002, the study has accurately forecasted 35 Nobel Prize winners.

Prof. Ryoo's Team Discovers Breakthrough Method to Create New Zeolite
A group of scientists led by Prof. Ryong Ryoo of the Department of Chemistry, KAIST, has found a method to direct the growth of zeolite, a crystalline substance that is frequently used as catalyst in the chemical and petrochemical industries, the university authorities said on Thursday (Sept. 10).
Ryoo"s research team successfully created ultrathin nano-sheets, only two nano-meters thick, that are efficiently used as long-life catalysts for hydrocarbon cracking and other petrochemical applications. The breakthrough finding, which is credited with taking acidic zeolite catalysts to the limit in terms of thickness, was published in the latest edition of the peer-review journal, "Nature."
A team from the Polytechnic Univeristy of Valencia, Spain, also contributed to the research.
Zeolites are already widely used in the petrochemical industry, but making the catalysts very thin means that reactant molecules can easily diffuse into the zeolite structure and product molecules can get out quickly. This improves the efficiency of the catalyst and reduces unwanted side reactions that can produce polymeric hydrocarbon "coke" that clogs the zeolite pores and eventually kills the catalytic activity, Prof. Yoo said.
To make the thin sheets, Ryoo and his team used a surfactant as a template to direct the growth of the zeolite structure. The surfactant molecule has a polar "head" group - with two quaternary ammonium groups around which the aluminosilicate zeolite crystal grows - and a long hydrocarbon "tail," which prevents the sheets from aggregating together into larger, three dimensional crystals. When the surfactant is removed, these flakes pile up randomly with gaps in between which further aids diffusion to the catalyst sites.
"Zeolite could be used as a catalyst to convert heavy oil into gasoline. Our new zeolite could provide even more possibilities, such as being used as catalysts for transforming methanol into gasline," Ryoo said.
Prof. Ryoo, a Distinguished Professor of KAIST, has won a variety of academic awards, which included the Top Scientist Award given by the Korean government in 2005 and the 2001 KOSEF Science and Technology Award for his work on the synthesis and crystal structure of mezzoporous silica.
Ryoo obtained his bachelor"s degree from Seoul National University in 1977, master"s from KAIST in 1979, and doctorate from Stanford University in 1985.
In 2006, Ryoo and his research team announced the discovery of a form of zeolite that can catalyze petrochemical reactions much more effectively than previous zeolites. Because of the potential of this to streamline the gasoline refining process, it was greeted as a "magical substance" by the South Korean press.

Professor Ryong Ryoo, selected as a scientist wished to resemble and to be 2006
Professor Ryong Ryoo, selected as a scientist wished to resemble and to be 2006
Professor Ryong Ryoo (Department of Chemistry) was selected as a scientist wished to resemble and to be 2006.
Professor Ryoo developed in 2000 world’s first nanoporous carbon material in which numberless several nanometer-sized holes were drilled. The development of this nanoporous material was introduced by international scientific journal NATURE in 2000 and 2001 and expected to contribute to the progress of mankind through the development of high efficiency fuel cell or ultra-light computer. Professor Ryoo also developed a new technology that can considerably improve the catalyst activation and stability of ‘Zeolite’, a main catalyst in the petrochemical industry, which was introduced by NATURE materials. The above achievements qualified Professor Ryoo for the selection.
‘Scientists wished to resemble and to be 2006’ were selected among scientists showing vigorous activities in the science and technology circle on the basis of their recent achievements, etc. by the Ministry of Science and Technology and the Korea Science Foundation, and total 10 scientists qualified to be the model of children and the youth were announced on August 24.
