Closer to the Dream: Graphene
A technique that allows easy and larger observation area of graphene’s crystal face was developed by Korean Research Team.
The research team, led by Professor Jeong Hui Tae (KAIST), consists of Doctorate candidate Kim Dae Woo, Dr. Kim Yoon Ho (primary author), Doctorate candidate Jeong Hyun Soo. The research is supported by WCU (World Class Research University) Development Plan, Mid-Aged Researcher Support Business and was published in the online edition of Nature Nanotechnology.
(Dissertation: Direct visualization of large0area graphene domains and boundaries by optical birefringency)
Professor Jeong’s team used the optical property of the liquid display used in LCD to visualize the size and shape of the single crystals along a flat surface. The visualization of the single crystal allowed the measurement of a near theoretical value of electrical conductivity of graphene.
Graphene has great electrical conductivity, transparent, mechanically stable, flexible, and is therefore regarded as the next generation electrical material. However the polycrystalinity of graphene meant that the actual electrical, mechanical properties were lower than the theoretical values. The reason was thought to be because of the size of the crystal faces and boundary structures.
Therefore, in order to create graphene that has good properties, observing the domain and boundary of graphene crystal faces is essential.
The new technique developed by the research team is another step towards commercializing transparent electrodes, flexible display, and electric materials like solar cells.

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.

KAIST's efforts begin to become the first Korean university establishing a "strategic technology management system."
KAIST completed the signing of business agreement with the Korea Strategic Trade Institute to establish a strategic technology management system on the 22nd of September.
The agreement between KAIST and Korea Strategic Trade Institute (under the Ministry of Knowledge Economy) encompasses 1) the establishment of processes for strategic technology management on campus, 2) development and accommodation of management system on par with major countries, and 3) protection and management through continued education and promotion.
Strategic technology management is necessary to prevent the illegal distribution of technologies developed in Korea to those countries and organizations of concern. The need for the management system arose due to the fact that technology transfer has become venerable to illegal export of strategic technologies.
The agreement between the two parties offer protection to KAIST when exporting strategic technologies as it necessitates the permission of the government prior to the technology transfer.

Future of Petrochemical Industry: The Age of Bio-Refineries
The concept of bio-refinery is based on using biomass from seaweeds and non-edible plant sources to produce various materials.
Bio-refineries has been looked into with increasing interest in modern times due to the advent of global warming (and the subsequent changes in the atmosphere) and the exhaustion of natural resources.
However past 20 years of research in metabolic engineering had a crucial limitation; the need to improve the efficiency of the microorganisms that actually go about converting biomass into biochemical materials.
In order to compensate for the inefficiency, Professor Lee Sang Yeop combined systems biology, composite biology, evolutionary engineering to form ‘systems metabolic engineering’.
This allows combining various data to explain the organism’s state in a multi-dimensional scope and respond accordingly by controlling the metabolism.
The result of the experiment is set as the cover dissertation of ‘Trends in Biotechnology’ magazine’s August edition.

IMMEDIATE RELEASE
Wireless electric trams at Seoul Amusement Park begin full operations.
KAIST’s On-Line Electric Vehicle (OLEV) becomes an icon of green technology, particularly for young students who aspire to transform their nation into the “vanguard of sustainability.”
Seoul, South Korea, July 19, 2011—As young students wrap up their school work before summer vacation in late July, Seoul Grand Park, an amusement park located south of Seoul, is busily preparing to accommodate throngs of summer visitors. Among the park’s routine preparations, however, there is something new to introduce to guests this summer: three wireless electric trams have replaced the old diesel-powered carts used by passengers for transportation within the park.
The Korea Advanced Institute of Science and Technology (KAIST) and the city of Seoul held a ceremony this morning, July 19, 2011, to celebrate their joint efforts to adopt a green public transportation system and presented park visitors with the three On-Line Electric Vehicles (OLEVs), which will be operated immediately thereafter. Approximately one hundred people, including science high school students across the nation, attended the ceremony and had a chance to ride the trams.
KAIST unveiled the prototype of an electric tram to the public in March 2010, and since then it has developed three commercial trams. The Korean government and the institute have worked on legal issues to embark on the full-scale commercialization of OLEV, and the long awaited approval from the government on such issues as standardization of the OLEV technology and road infrastructure, regulation of electromagnetic fields and electricity safety, and license and permits for vehicle eligibility, finally came through.
The On-Line Electric Vehicle (OLEV) is no ordinary electric car in that it is remotely charged via electromagnetic fields created by electric cables buried beneath the road. Unlike other currently available electric cars, OLEV can travel unlimited distances without having to stop to recharge. OLEV also has a small battery onboard, which enables the vehicle to travel on roads that are not equipped with underground power cables. This battery, however, is only one-fifth of the size of a conventional electric vehicle battery, resulting in considerable savings in the cost, size, and weight of the vehicle.
The OLEV project was initiated in 2009 as a method of resolving the battery problems of electric cars in a creative and disruptive way. KAIST came up with the idea of supplying electricity directly to the cars instead of depending solely on the onboard battery for power. Since then, the university has developed core technologies related to OLEV such as the “Shaped Magnetic Field in Resonance (SMFIR),” which enables an electric car to collect the magnetic fields and convert them into electricity, and the “Segment Technology,” which controls the flow of electromagnetic waves through an automatic power-on/shut-down system, thereby eliminating accidental exposure of the electromagnetic waves to pedestrians or non-OLEV cars.
According to KAIST, three types of OLEV have been developed thus far: electric buses, trams, and sport utility vehicles (SUVs). The technical specifications of the most recently developed OLEV (an electric bus), the OLEV research team at the university said, are as follows:
· Power cables are buried 15cm beneath the road surface.
· On average, over 80% power transmission efficiency is achieved.
· The distance gap between the road surface and the underbody of the vehicle is 20cm.
· The OLEV bus has a maximum electricity pickup capacity of 100kW.
· The OLEV bus complies with international standards for electromagnetic fields (below 24.1 mG).
The eco-friendly electric trams at Seoul Grand Park consume no fossil fuels and do not require any overhead wires or cables. Out of the total circular driving route (2.2km), only 16% of the road, 372.5m, has the embedded power lines, indicating that OLEV does not require extensive reconstruction of the road infrastructure. The city government of Seoul signed a memorandum of understanding with KAIST in 2009 as part of its initiatives to curtail emissions from public transportation and provide cleaner air to its citizens. Both parties plan to expand such collaboration to other transportation systems including buses in the future.
KAIST expects the OLEV technology to be applied in industries ranging from transportation to electronics, aviation, maritime transportation, robotics, and leisure. There are several ongoing international collaborative projects to utilize the OLEV technology for a variety of transportation needs, such as inner city commute systems (bus and trolley) and airport shuttle buses, in nations including Malaysia, US, Germany, and Denmark.

Biomimetic Carbon Nanotube Fiber Synthesis Technology Developed
The byssus of the mussel allows it to live in harsh conditions where it is constantly battered by crashing waves by allowing the mussel to latch onto the seaside rocks. This particular characteristic of the mussel is due to the unique structure and high adhesiveness of the mussel’s byssus.
KAIST’s Professor Hong Soon Hyung (Department of Material Science and Engineering) and Professor Lee Hae Shin (Department of Chemistry) and the late Professor Park Tae Kwan (Department of Bio Engineering) were able to reproduce the mussel’s byssus using carbon nanotubes.
The carbon nanotube, since its discovery in 1991, was regarded as the next generation material due to its electrical, thermal, and mechanical properties. However due to its short length of several nanometers, its industrial use was limited.
The KAIST research team referred to the structure of the byssus of the mussel to solve this problem.
The byssus is composed of collagen fibers and Mefp-1 protein which are in a cross-linking structure. The Mefp-1 protein has catecholamine that allows it to bind strongly with the collagen fiber.
In the artificial structure, the carbon nanotube took on the role of the collagen fibers and the macromolecular adhesive took on the role of the catecholamine. The result was a fiber that was ultra-light and ultra-strong.
The results of the experiment were published in the Advanced Materials magazine and is patent registered both domestically and internationally.
