Energy Storage Using Oxygen to Boost Battery Performance
Researchers have presented a novel electrode material for advanced energy storage device that is directly charged with oxygen from the air. Professor Jeung Ku Kang’s team synthesized and preserved the sub-nanometric particles of atomic cluster sizes at high mass loadings within metal-organic frameworks (MOF) by controlling the behavior of reactants at the molecular level. This new strategy ensures high performance for lithium-oxygen batteries, acclaimed as a next-generation energy storage technology and widely used in electric vehicles. Lithium-oxygen batteries in principle can generate ten times higher energy densities than conventional lithium-ion batteries, but they suffer from very poor cyclability. One of the methods to improve cycle stability is to reduce the overpotential of electrocatalysts in cathode electrodes. When the size of an electrocatalyst material is reduced to the atomic level, the increased surface energy leads to increased activity while significantly accelerating the material’s agglomeration. As a solution to this challenge, Professor Kang from the Department of Materials Science and Engineering aimed to maintain the improved activity by stabilizing atomic-scale sized electrocatalysts into the sub-nanometric spaces. This is a novel strategy for simultaneously producing and stabilizing atomic-level electrocatalysts within metal-organic frameworks (MOFs). Metal-organic frameworks continuously assemble metal ions and organic linkers. The team controlled hydrogen affinities between water molecules to separate them and transfer the isolated water molecules one by one through the sub-nanometric pores of MOFs. The transferred water molecules reacted with cobalt ions to form di-nuclear cobalt hydroxide under precisely controlled synthetic conditions, then the atomic-level cobalt hydroxide is stabilized inside the sub-nanometric pores. The di-nuclear cobalt hydroxide that is stabilized in the sub-nanometric pores of metal-organic frameworks (MOFs) reduced the overpotential by 63.9% and showed ten-fold improvements in the life cycle. Professor Kang said, “Simultaneously generating and stabilizing atomic-level electrocatalysts within MOFs can diversify materials according to numerous combinations of metal and organic linkers. It can expand not only the development of electrocatalysts, but also various research fields such as photocatalysts, medicine, the environment, and petrochemicals.” This study was reported in Advanced Science (Title: Autogenous Production and Stabilization of Highly Loaded Sub-Nanometric Particles within Multishell Hollow Metal-Organic Frameworks and Their Utilization for High Performance in Li-O2 Batteries). This research was mainly supported by the Global Frontier R&D Program of the Ministry of Science, ICT & Planning (Grant No. 2013M3A6B1078884) funded by the Ministry of Science, ICT & Future Planning, and the National Research Foundation of Korea (Grant No. 2019M3E6A1104196).

ASPIRE League 2014: E-Olympics among Five Asian Universities
About 150 undergraduate students from five leading science and technology (S&T) universities in Asia met at the KAIST campus to attend the E-Olympics on August 7-9, 2014. The E-Olympics began as a student exchange conference held under the Asian Science and Technology Pioneering Institutes of Research and Education (ASPIRE) League, which offers a variety of events, such as workshops, sports matches, lab visits, special lectures, and art performances, to promote academic and research collaborations and cultural sharing between the students of the league member universities. Founded in 2009, the ASPIRE League is a university consortium consisted of five top S&T universities in Asia: KAIST in Korea, the Hong Kong University of Science and Technology (HKUST) and Tsinghua University in China, Nanyang Technological University (NTU) in Singapore, and Tokyo Institute of Technology (Tokyo Tech) in Japan. The ASPIRE League aims to provide a knowledge and technology hub for innovation in Asia through the advancement of science and technology and the development of human resources. Since its start, the ASPIRE League has been holding an annual conference with programs for research collaboration, student exchange, educational cooperation, and satellite laboratories among professors, senior managers, and students of the member universities. This year, however, the consortium decided to dedicate the conference to students by holding the E-Olympics. Each university sent 30 students to KAIST for the participation of the E-Olympics. For three days, participating students engaged in discussions and presentations at academic workshops; held athletic games including a relay race, basketball, and a rowing race; and toured a few KAIST laboratories, among them: the E-mobility Research Center, the Bio-imaging and Cell Signaling Research Center, the Mechatronics Systems and Control Center, and the Center of Field Robotics for Innovation, Exploration and Defense. The students also attended a music concert performed by a KAIST student club and a lecture entitled “Entrepreneurship through Global Networking” that emphasized the importance of personnel networking in transferring technological innovation into business opportunities. Chang-Dong Yoo, the Dean of the International Office at KAIST, said, “The E-Olympics will offer students from top science and technology universities in Asia opportunities to interact with each other on a more personal level. I hope that through many of the E-Olympics programs, the students will learn about each other’s culture and academic strength and develop a sense of community to create a “New Asia” by working together.”

The third International Presidential Forum to be held, participants of the 2010 Presidential Forum engaged in an in-depth discussion about the direction that research universities should take in the 21st Century. On its opening, President Nam Pyo Suh delivered a congratulatory message saying, “This forum is a meaningful gathering where research universities will suggest role models and find ways research universities can contribute to the progress of mankind in this century.” Following, Lee Ki Jun, CEO of the Korean Federation of Science and Technology Societies said, “The common goal of the world’s research universities is to solve the problems mankind is facing together. I believe that the discussion we will hold today at the forum will point to the future direction of research universities.” “To produce next generation engineers meeting global standards, exchange and dual degree programs between universities must be strengthened,” said Lars Pallesen, President of the Technical University of Denmark. “Research universities must support the exchange between students beyond cultural and national borders to adapt to the global market.” Ichiro Okura, Vice President of Tokyo Institute of Technology, presented on the “Asian Science and Technology Pioneering Institutes of Research and Education, ASPIRE.” ASPIRE is a community created by the coalition between science and technology universities in the Far East. Its purpose is to contribute to sustainable global growth by educating high-quality human resources and lead Asia’s technology innovation based on science and technology development. “For research universities to solve today’s global issues, universities must create new ideas by performing fundamental studies and developing innovative technology. The financial resources of universities must be focused with choices based on results,” remarked President Suh. Zaini Ujang, Vice-President of the Universiti Teknologi Malaysia stated that “the Malaysian government is planning on converting from a ‘labor-intensive economy’ to an ‘innovative leading economy’ with the goal of joining the advanced countries by 2020. In today’s science and technology era where innovative technology is necessary, research universities have an important role of developing the knowledge environmental system to lead the world economy.” Vice-President Ujang then explained what strategies Malaysian research universities devised in the innovative leading economy era to create research universities that bring creativity and innovation. Tod A. Laursen, President of KUSTAR, said that “KUSTAR has a leading role in bringing science and technology and manpower necessary in converting the oil-centered economy of UAE to a knowledge-based economy. KUSTAR will continuously strengthen international cooperation to become not only the best engineering university in the Arab region but in the world.” At this year’s forum, thirty international presidents and vice presidents from 24 universities in 15 countries including Georgia Tech, Technical University of Denmark, Technion-Israel Institute of Technology, University of Queensland, Tokyo University, Nanyang Technological University, University Teknologi Malaysia and Hong Kong Institute of Science and Technology along with forty national figures such as the presidents of Hanyang University and Handong Global University, governmental bureaucrats and representatives from national business and institutions participated.
Op-Ed by Dean Ravi Kumar, KAIST Business School, for MK English News
Professor Ravi Kumar, Dean of Business School at KAIST, wrote an op-ed for MK English News, dated February 3, 2010, on "Korea’s doing business in India". Below is his article: India: Opportunity or Frustration? by Dr. Ravi Kumar, Dean of KAIST Business School On January 26, President Lee Myung-bak was the chief guest at India’s Republic Day parade and festivities, an honor that has been bestowed on Vladimir Putin of Russia and Nicolas Sarkozy of France in recent years. President Lee signed a strategic partnership agreement with Prime Minister Manmohan Singh, was successful in getting the Indian government to issue permits for POSCO to break ground on their US$ 12 billion steel plant and is positioning Korea as a serious contender in India’s future purchase of nuclear power plants and trainer aircraft. Doosan Heavy was successful in getting a billion dollar order last week to build a coal-fired power plant in India and Hyundai Motors has doubled its car production capacity in Chennai with 20% Indian market share. Samsung and LG have dominant market share in the Indian consumer electronics and home appliances sector, hiring thousands of Indians this year to support their growth. Wow, all this points to India and Korea on target to double their trade to US$ 30 billion by 2014. Last week, a group of our KAIST IMBA students with considerable business experience interviewed me for one of their class projects. Their topic: Indian culture/society and its impact on doing business in India. One of their questions probed the notion of time in Indian culture and business etiquette since they had heard that Indians are not on time for appointments/meetings. I had to explain to them that India originated from one of the oldest civilization (Indus Valley) that goes back five thousand years and this is one reason that allows Indians to think of time as being continuous and forever. Another aspect of culture that impacts Indian sense of endless time is that of re-incarnation—Indians who are predominantly Hindus believe that one is reborn again and again until one lives a purely spiritual life and becomes one with the divine being. And finally, Indians believe in fate, that their past lives (and sometimes, where the planets were located when they were born) define, in some sense, the kind of life they are going to lead in this current life. Given these three factors, there is no sense of “palli palli” in Indian life and this can be very frustrating to foreigners. So, my advice to Korean companies and executives--have a lot of patience and be ready for endless diversity. The country that can send sophisticated moon probes can also not have electricity or clean water for millions of its citizens. When you travel from one state to another, beware that the actual language, food preparation, philosophy of government and even clothing that people wear may differ remarkably. India is really like the European Union, with different languages, different state governments, different cultures and a lot of the infrastructure still to be built. An opportunity, you bet—but tomorrow, maybe not!
World Research University Heads Discuss Challenges in Global Financial Turmoil at 2009 International Presidential Forum in Seoul
Leaders of the world"s major research universities discussed the impact of the global economic crisis on institutions of higher learning and their research activities in particular and exchanged opinions and visions on ways to increase cooperation with governments and industry at a symposium organized by KAIST Monday (Sept. 21) at the Westin Chosun Hotel in Seoul. More than 50 participants of the 2nd International Presidential Forum on Global Research Universities represented institutions in North America, Europe, Southeast Asia, Australia, China and Japan. They were joined by 20 presidents of Korean universities and two dozens of leaders from industry and the government. Under the main subject of "Challenges to Global Research Universities," the international symposium proceeded in four panel sessions. The subjects of each session and their keynote speakers were: -- "Institutional Management in Times of Financial Crisis" by Kurt Kutzler, President of Berlin Institute of Technology -- "Innovations in Education & Research" by Brian Cantor, Vice Chancellor of University of York -- "Globalization of Institutes of Higher Learning" by Gary Schuster, Provost and Executive Vice President of Georgia Institute of Technology -- "The Roles of Government, University and Industry in Green Technology Development" by KAIST President Nam-Pyo Suh KAIST President Suh expressed deep gratitude to all participants for their presentations focused on how universities weathered the difficulties from the economic turmoil and how they were continuing efforts for innovation in research and education. He observed that the 2009 International Presidential Forum was again most successful and productive after the first in 2008 and offered a precious opportunity for leaders of research universities to establish effective networking among their institutions. "The world has witnessed a global financial turmoil of unseen magnitude and many nations are still struggling under the devastating impacts. While universities were no exception in facing economic turmoil, they have realized renewed pressures and expectations from their respective communities to provide answers to the great challenges,” he said in his welcoming remarks. "The conference I am sure will have a far-reaching influence on the course our research universities will take to shoulder greater responsibilities for building a better future of the mankind." Some of the participants in the 2009 International Presidential Forum came to KAIST’s Daejeon campus to take part in the EEWS (energy, environment, water and sustainability) workshop which was held on Tuesday, Sept. 22. The Chronicle of Higher Learning, the Washington-based newspaper specializing in university education, reported from Seoul that the Forum revealed that, while American universities struggle amid the harshest economic climate in a generation, institutions in much of the rest of the world are sheltered from the fallout by strong government backing. “Delegates to a conference of university presidents (in Seoul on Monday, Sept. 22) heard that colleges in Asia and Europe are pushing ahead with expansion plans – even as their U.S. counterparts cut back. “The 2009 International Presidential Forum… was marked by a sharp divide in the tone set by European, Asian, and U.S. college leaders. The Americans often sounded a deeply gloomy note,” The Chronicle reported. “Never before has the impact been this bad,” the paper quoted Vishwanath Prasad, vice president for research and economic development at the University of North Texas, as saying. On the other hand, Yves Poilane, vice president of the Paris Institute of Technology, said, according to The Chronicle, “The largely state financing of most European universities has so far acted as a shelter, and higher education remains a priority for both European and French Universities.” The Korea Herald, published in Seoul, said in its Sept. 23 editorial: “This week in Seoul, a symposium of leaders from international and Korean research universities heard top scholars and administrators reveal how their schools have suffered through the year under reduced government subsidies and private endowments which forced them to postpone various globalization schemes and cut down on research expenditures. Applications for master"s and Ph.D. programs declined while large percentages of graduates failed to find jobs. “With their country showing a rapid pace of recovery, universities in Korea are in a better situation than many of their overseas counterparts, especially considering the substantial government outlays for research and development in "low carbon, green growth" projects that are largely dependent on research universities. The more the government seeks their direct contributions, the harder universities should try to increase transparency and accountability in the use of taxpayer money, so as not to betray the nation"s trust in them. “In the wake of the global economic crisis, academia, government and industry find themselves in closer ties as they share new concepts of innovation and development in a common quest for growth. The tripartite cooperation has new significance in the recovery process. To achieve any development objectives, the other two partners must prioritize the funding of universities.”
