[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 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.

2011 International Presidential Forum on Global Research Universities
KAIST’s 4th International Presidential Forum Held in Seoul on November 8, 2011
The largest annual congregation of university presidents in Asia invited leaders from academia, government, and industry for talks on issues related to higher education in the Age of Globalization.
Borderless and Creative Education: the ability to cross borders a crucial key to dominate the information era
Seoul, Republic of Korea, November 8, 2011—The Korea Advanced Institute of Science and Technology (KAIST) hosted the “2011 International Presidential Forum on Global Research Universities (IPFGRU)” on Tuesday, November 8, 2011 at the Millennium Hilton Hotel in Seoul.
With more than 120 participants from 44 institutions in 27 countries present, the full-day forum provided participants with an opportunity to discuss challenges and responsibilities facing higher education in a time of globalization that has resulted from an ever-growing demand for technological innovation.
In his plenary speech, Dr. Robert Birgeneau, Chancellor of UC Berkeley, stressed that “Higher educational intuitions must be prepared to drive innovation and enhance competitiveness by educating a highly trained workforce that will have the critical skills necessary to solve problems and lead in today’s interdependent world.”
“Finding solutions to the world’s most challenging problems will depend on the ability to cross borders: national borders, border between different fields of discipline and research, and borders between academe, government, and industry,” said Chancellor Birgeneau to address the importance of “borderless and creative education,” the theme of the forum.
Other major keynote speakers were Jörg Steinbach, President of Technische Universität Berlin, Lars Pallesen, President of Technical University of Denmark, Paul F. Greenfield, President of University of Queensland, Marcelo Fernandes de Aquino, President of the University of the Sinos Valley (UNISINOS), and Eden Woon, Vice President of the Hong Kong University of Science and Technology.
Dr. Nam-Pyo Suh, President of KAIST, gave talks on the university’s new education plan, “The I-Four Education,” at the afternoon session. The four Is are information technology (IT), independent learning, integrated knowledge acquisitions, and an international learning environment.
“In this format, there are no formal lectures,” President Suh explained. “A group of students learn together by using the materials available on the internet, doing homework and conducting experiments together. Pre-recorded lectures are delivered in English by I-Four professors, some of them regular KAIST professors and some professors in other countries who participate in the I-Four Program as consulting professors.”
He added, “The overall purpose of the I-Four Education Program is to encourage students to learn independently, gain exposure to the best lectures by the most eminent professors in the world, accelerate the development of a global frame of reference in the students by dealing with information available throughout the world, and provide an integrated learning environment by using diverse examples from many disciplines to achieve understanding of basic principles.”
The 2011 IPFGRU, the fourth forum since its inception in 2008, rose to prominence in the past years as an international network for leaders of research universities from around the world to share information and exchange views about contemporary issues in higher education.
At this year’s forum, entitled “Borderless and Creative Education,” speakers took a deeper look into the transitions and transformations many research universities are undergoing today, delving into the following topics: the development of e-learning and cyber campuses; increased student mobility and international collaborations; multi-disciplinary and convergence approaches in research and education; and methodology of nurturing future global leaders.
Participants also discussed experiences and accomplishments earned from their own endeavors to accommodate such changes and presented ways to strengthen internationalization and improve the academic and research competitiveness of universities.
The 2011 International Presidential Forum on Global Research Universities (IPFGRU) was organized by KAIST and sponsored by the Ministry of Education, Science and Technology, POSCO, Hyundai Motor Company, Samsung Heavy Industries, S-Oil, and Elsevier Korea.

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.

10th Annual POSTECH-KAIST Competition: 'Revenge of the Blue Dragon'
KAIST is out for revenge after losing last year in the POSTECH-KAIST Annual Competition, a college rivalry between the two science and technology schools. The competition was held over two days, 23rd and 24th of September and involved 2,000 students from the two universities.
The POSTECH-KAIST Competition, also known as ‘Science War,’ is an annual event which started in 2002 to encourage active interaction between the two universities and increase public interest in science and technology education. The 2011 Competition marked the 10th competition as the 2009 competition was cancelled due to “swine influenza.”
The Competition is held every mid-September, and the title of the competition depends on the venue; the name of the host university is marked last by convention, hence the 2011 Science War was known as ‘POSTECH-KAIST Competition’ since the competition was held in KAIST.
The competition is composed of Hacking Competition, Science Trivia, Artificial Intelligence Programming Contest, StarCraft, Soccer, Baseball, and Basketball.
800 points are up for grabs, and the university with the most points wins. Both universities have won four times and lost four times and therefore promises to be a mouthwatering encounter this year.
Apart from the various competitions, interaction between clubs, cheerleading performances, and congratulatory concert (Dynamic Duo) were prepared. In addition, a beer party was hosted from 11pm of the first day of the competition to 2am the following day which brought students from the two universities closer together.
President Seo Nam Pyo of KAIST commented, “I am very happy that the two universities at the forefront of Korean Science and Technology can come together to interact and compete wholeheartedly through the 10th POSTECH-KAIST Competition” and that, “I hope that the students can exhibit the skills and ability that they have practiced hard on and uphold the proud history and tradition of KAIST.”

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.

Late Dr. Ryu Geun Chul's Achievements and Generous Contributions
First Doctor in the field of Korean Traditional Medicine
The late Dr. Ryu was born in 1926 and is the father figure of Korea’s Traditional Medicine and is its First Doctor (1976 Kyung Hee University), and was the vice-professor of Kyung Hee University of Medicine, Vice-Director of Kyung Hee Institute of Korean Traditional Medicine, and was the first chairman of the Association of Korea Oriental Medicine. He developed the painless acupuncture administering device for the first time in Korea in 1962, and succeeded in anesthetizing a patient for cesarean procedure using acupuncture in 1972.
He even was the first to receive a medical engineering doctorate degree from the Moscow National Engineering School in April of 1996 and developed a stroke rehabilitation machine.
Korea’s Most Generous Donor
Dr. Ryu surprised the world by donating 57.8billion Won worth of real estate to KAIST in August of 2008. Dr. Ryu revealed that his reason for donating such a huge sum to KAIST was due to its focused students giving him the belief that the future of Korea is at KAIST and that the development of science and technology is necessary for Korea to develop into a world class nation and KAIST is the institute most suitable to lead Korea in the field.
Dr. Ryu lived on KAIST campus after donating his entire fortune and even established ‘KAIST scholars and spacemen health research center’ and ‘Dr. Ryu Health Clinic’ as he also wanted to donate his knowledge.
Even when he was a professor at Moscow National Engineering University in the late 1990s he carried out free medical work throughout Korea and in recognition of his devoted work, he was named honorary citizen from Chun Ahn city, San Chung city, and DaeJeon city. In 2007 he donated 450million Won to Cheon Dong Elementary School in Chun Ahn city to build a gymnasium and an indoor golf practice range.
Role as Science and Technology Public Relations Officer
Dr. Ryu volunteered to numerous lectures and interviews after donation to advertise science and technology. His belief that the development of science and technology is necessary for Korea’s development was the driving force behind his efforts at increasing interest and support for the field of science and technology.
In addition, through interviews with MBC, KBS, SBS, KTV, Joong Ang Newspapers, Dong Ah Newspaper and other media mediums, Dr. Ryu improved the public perception on donations whilst increasing the pride of scientists and researchers by highlighting their importance and the importance of science and technology.
