2013 International Conference for the Integration of Science, Technology, and Society at KAIST (ICISTS-KAIST)
The International Conference for the Integration of Science, Technology, and Society at KAIST (ICISTS-KAIST) is a global forum organized by KAIST undergraduate students to promote the exchange of ideas and facilitate the discussion of issues that are important to science, technology, society, and higher education. The ICISTS-KAIST conference has been held annually every summer since 2005, inviting distinguished speakers and guests from all around the world to share their insights and expertise with students gathered from Korea and abroad. Last year alone, more than 300 students from 22 nations and 40 speakers participated in the event. Originally, the ICISTS-KAIST was established by KAIST students who were inspired by the Harvard Project for Asian and International Relations (HPAIR), which is one of the Harvard’s largest annual student conferences in Asia. This year, 335 students from 103 universities in 22 countries joined the conference that was held on August 5th-9th in Daejeon, making the 2013 ICISTS-KAIST the biggest science and engineering gathering hosted by university students in Asia. About 36% of the participants were international students. The theme of the conference was “Perfect Alliance: Coexistence for Human Society,” in which students and speakers addressed issues on how to harmonize the speed of scientific progress with the development of important values in society, as well as to explore solutions to overcome the chasm, if any, between the boundaries of science and society. In his opening remarks, President Steve Kang said, “Creativity and innovation are born out of openness. Therefore, it is essential for young scientists and engineers to communicate with people from different cultural and political backgrounds. Through this kind of global interaction and exchange of ideas and views, students will have an opportunity to deepen their understanding of the world and to better examine the purpose of their intellectual exploration in science and technology.” At the 2013 ICISTS-KAIST, 25 distinguished speakers participated including Walter Bender, a former director of the Media Lab at MIT and David Christian, a professor of Macquarie University in Australia.

A KAIST research team developed in vivo flexible large scale integrated circuits
Daejeon, Republic of Korea, May 6th, 2013–-A team led by Professor Keon Jae Lee from the Department of Materials Science and Engineering at KAIST has developed in vivo silicon-based flexible large scale integrated circuits (LSI) for bio-medical wireless communication. Silicon-based semiconductors have played significant roles in signal processing, nerve stimulation, memory storage, and wireless communication in implantable electronics. However, the rigid and bulky LSI chips have limited uses in in vivo devices due to incongruent contact with the curvilinear surfaces of human organs. Especially, artificial retinas recently approved by the Food and Drug Administration (refer to the press release of FDA"s artificial retina approval) require extremely flexible and slim LSI to incorporate it within the cramped area of the human eye. Although several research teams have fabricated flexible integrated circuits (ICs, tens of interconnected transistors) on plastics, their inaccurate nano-scale alignment on plastics has restricted the demonstration of flexible nano-transistors and their large scale interconnection for in vivo LSI applications such as main process unit (MPU), high density memory and wireless communication. Professor Lee"s team previously demonstrated fully functional flexible memory using ultrathin silicon membranes (Nano Letters, Flexible Memristive Memory Array on Plastic Substrates), however, its integration level and transistor size (over micron scale) have limited functional applications for flexible consumer electronics. Professor Keon Jae Lee"s team fabricated radio frequency integrated circuits (RFICs) interconnected with thousand nano-transistors on silicon wafer by state-of-the-art CMOS process, and then they removed the entire bottom substrate except top 100 nm active circuit layer by wet chemical etching. The flexible RF switches for wireless communication were monolithically encapsulated with biocompatible liquid crystal polymers (LCPs) for in vivo bio-medical applications. Finally, they implanted the LCP encapsulated RFICs into live rats to demonstrate the stable operation of flexible devices under in vivo circumstances. Professor Lee said, "This work could provide an approach to flexible LSI for an ideal artificial retina system and other bio-medical devices. Moreover, the result represents an exciting technology with the strong potential to realize fully flexible consumer electronics such as application processor (AP) for mobile operating system, high-capacity memory, and wireless communication in the near future." This result was published in the May online issue of the American Chemical Society"s journal, ACS Nano (In vivo Flexible RFICs Monolithically Encapsulated with LCP). They are currently engaged in commercializing efforts of roll-to-roll printing of flexible LSI on large area plastic substrates.

Top Ten Ways Biotechnology Could Improve Our Everyday Life
The Global Agenda Council on Biotechnology, one of the global networks under the World Economic Forum, which is composed of the world’s leading experts in the field of biotechnology, announced on February 25, 2013 that the council has indentified “ten most important biotechnologies” that could help meet rapidly growing demand for energy, food, nutrition, and health. These new technologies, the council said, also have the potential to increase productivity and create new jobs. “The technologies selected by the members of the Global Agenda Council on Biotechnology represent almost all types of biotechnology.Utilization of waste, personalized medicine,and ocean agricultureare examples of the challenges where biotechnology can offer solutions,”said Sang Yup Lee, Chair of the Global Agenda Council on Biotechnology and Distinguished Professor in the Department of Chemical and Biomolecular Engineering at the Korea Advanced Institute of Science and Technology (KAIST). He also added that “the members of the council concluded that regulatory certainty, public perception, and investment are the key enablers for the growth of biotechnology.” These ideas will be further explored during “Biotechnology Week” at the World Economic Forum’s Blog (http://wef.ch/blog) from Monday, 25 February, 2013. The full list follows below: Bio-based sustainable production of chemicals, energy, fuels and materials Through the last century, human activity has depleted approximately half of the world’s reserves of fossil hydrocarbons. These reserves, which took over 600 million years to accumulate, are non-renewable and their extraction, refining and use contribute significantly to human emissions of greenhouse gases and the warming of our planet. In order to sustain human development going forward, a carbon-neutral alternative must be implemented. The key promising technology is biological synthesis; that is, bio-based production of chemicals, fuels and materials from plants that can be re-grown. Engineering sustainable food production The continuing increase in our numbers and affluence are posing growing challenges to the ability of humanity to produce adequate food (as well as feed, and now fuel). Although controversial, modern genetic modification of crops has supported growth in agricultural productivity. In 2011, 16.7 million farmers grew biotechnology-developed crops on almost 400 million acres in 29 countries, 19 of which were developing countries. Properly managed, such crops have the potential to lower both pesticide use and tilling which erodes soil. Sea-water based bio-processes Over 70% of the earth surface is covered by seawater, and it is the most abundant water source available on the planet. But we are yet to discover the full potential of it. For example with halliophic bacteria capable of growing in the seawater can be engineered to grow faster and produce useful products including chemicals, fuels and polymeric materials. Ocean agriculture is also a promising technology. It is based on the photosynthetic biomass from the oceans, like macroalgae and microalgae. Non-resource draining zero waste bio-processing The sustainable goal of zero waste may become a reality with biotechnology. Waste streams can be processed at bio-refineries and turned into valuable chemicals and fuels, thereby closing the loop of production with no net waste. Advances in biotechnology are now allowing lower cost, less draining inputs to be used, including methane, and waste heat. These advances are simplifying waste streams with the potential to reduce toxicity as well as support their use in other processes, moving society progressively closer to the sustainable goal of zero waste. Using carbon dioxide as a raw material Biotechnology is poised to contribute solutions to mitigate the growing threat of rising CO2 levels. Recent advances are rapidly increasing our understanding of how living organisms consume and use CO2. By harnessing the power of these natural biological systems, scientists are engineering a new wave of approaches to convert waste CO2 and C1 molecules into energy, fuels, chemicals, and new materials. Regenerative medicine Regenerative medicine has become increasingly important due to both increased longevity and treatment of injury. Tissue engineering based on various bio-materials has been developed to speed up the regenerative medicine. Recently, stem cells, especially the induced pluripotent stem cells (iPS), have provided another great opportunity for regenerative medicine. Combination of tissue engineering and stem cell (including iPS) technologies will allow replacements of damaged or old human organs with functional ones in the near future. Rapid and precise development and manufacturing of medicine and vaccines A global pandemic remains one of the most real and serious threats to humanity. Biotechnology has the potential to rapidly identify biological threats, develop and manufacture potential cures. Leading edge biotechnology is now offering the potential to rapidly produce therapeutics and vaccines against virtually any target. These technologies, including messenger therapeutics, targeted immunotherapies, conjugated nanoparticles, and structure-based engineering, have already produced candidates with substantial potential to improve human health globally. Accurate, fast, cheap, and personalized diagnostics and prognostics Identification of better targets and combining nanotechnology and information technology it will be possible to develop rapid, accurate, personalized and inexpensive diagnostics and prognostics systems. Bio-tech improvements to soil and water Arable land and fresh water are two of the most important, yet limited, resources on earth. Abuse and mis-appropriation have threatened these resources, as the demand on them has increased. Advances in biotechnology have already yielded technologies that can restore the vitality and viability of these resources. A new generation of technologies: bio-remediation, bio-regeneration and bio-augmentation are being developed, offering the potential to not only further restore these resources, but also augment their potential. Advanced healthcare through genome sequencing It took more than 13 years and $1.5 billion to sequence the first human genome and today we can sequence a complete human genome in a single day for less than $1,000. When we analyze the roughly 3 billion base pairs in such a sequence we find that we differ from each other in several million of these base pairs. In the vast majority of cases these difference do not cause any issues but in rare cases they cause disease, or susceptibility to disease. Medical research and practice will increasingly be driven by our understanding of such genetic variations together with their phenotypic consequences.

KAIST Develops Wireless Power Transfer Technology for High Capacity Transit
KAIST and the Korea Railroad Research Institute (KRRI) have developed a wireless power transfer technology that can be applied to high capacity transportation systems such as railways, harbor freight, and airport transportation and logistics. The technology supplies 60 kHz and 180 kW of power remotely to transport vehicles at a stable, constant rate. KAIST and KRRI successfully showcased the wireless power transfer technology to the public on February 13, 2013 by testing it on the railroad tracks at Osong Station in Korea. Originally, this technology was developed as part of an electric vehicle system introduced by KAIST in 2011 known as the On-line Electric Vehicle (OLEV). OLEV does not need to be parked at a charging station to have a fully powered battery. It gets charged while running, idling, and parking, enabling a reduction in size of the reserve battery down to one-fifth of the battery on board a regular electric car. The initial models of OLEV, a bus and a tram, receive 20 kHz and 100 kW power at an 85% transmission efficiency rate while maintaining a 20cm air gap between the underbody of vehicle and the road surface. OLEV complies with the national and international standards of 62.5 mG, a safety net for electromagnetic fields. In July 2013, for the first time since its development, OLEV will run on a regular road, an inner city route in the city of Gumi, requiring 40 minutes of driving each way. Today’s technology demonstration offers further support that OLEV can be utilized for large-scale systems. Professor Dong-Ho Cho, Director of Center for Wireless Power Transfer Technology Business Development at KAIST, explained the recent improvements to OLEV: “We have greatly improved the OLEV technology from the early development stage by increasing its power transmission density by more than three times. The size and weight of the power pickup modules have been reduced as well. We were able to cut down the production costs for major OLEV components, the power supply, and the pickup system, and in turn, OLEV is one step closer to being commercialized.” If trains receive power wirelessly, the costs of railway wear and tear will be dramatically reduced. There will be no power rails, including electrical poles, required for the establishment of a railway system, and accordingly, lesser space will be needed. Tunnels will be built on a smaller scale, lowering construction costs. In addition, it will be helpful to overcome major obstacles that discourage the construction of high speed railway systems such as noise levels and problems in connecting pantograph and power rails. KAIST and KRRI plan to apply the wireless power transfer technology to trams in May and high speed trains in September.

A Substance with Amazingly Improved Efficiency of Capturing Carbon Dioxides Developed
From left to right: Prof.Ali Coskun, Prof. Cafer T. Yavuz and Prof. Yousung Jung - Selectivity of CO2 increased by 300 times in comparison to nitrogen, published in Nature Communications- KAIST EEWS graduate school’s joint research team led by Prof. Cafer T. Yavuz, Prof. Ali Coskun, and Prof. Yousung Jung has developed the world"s most efficient CO2 absorbent that has 300 times higher carbon dioxide selectivity in comparison to nitrogen. Recently, the importance of CCS* technology, which is about capturing, storing and treating carbon dioxides, has begun to emerge world-widely as a practical alternative for the response to climate change. * CCS : Carbon Capture and sequestration Current carbon dioxide capturing technologies are wet capturing using liquid absorbent, dry capturing using solid absorbent and separation-membrane capturing using a thin membrane like a film. For the places like power plant and forge, where the emission of carbon dioxides is huge, the main task is to maintain the capturing efficiency under extremely hot and humid conditions. The previously studied dry absorbents, such as MOF or zeolite, had the disadvantages of instability in moist conditions and expensive cost for synthesis. On the other hand, the research team"s newly discovered dry absorbent, named ‘Azo-COP’, can be synthesized without any expensive catalysts so the production cost is very low. It is also stable under hot and humid conditions. COP is a structure consisting of simple organic molecules combined into porous polymer and is the first dry carbon dioxide capturing material developed by this research team. The research team introduced an additional functional group called "Azo" to the substance, so that it can selectively capture carbon dioxides among the mixture of gas. Azo-COP, which includes ‘Azo’ functional group, is manufactured easily by using common synthesis methods, and impurities are removed simply by using cheap solvents like water and acetone instead of expensive catalysts. As a result, the manufacturing cost has lowered drastically. Especially, Azo-COP is combined with carbon dioxides by weak attraction force rather than chemical attraction so the recycling energy cost for the absorbent can be reduced innovatively, and it is expected to be used for capturing substances other than carbon dioxides in various areas as it is stable under extreme conditions even under 350 degrees Celsius. This research is supported by Korea Carbon Capture&Sequestration R&D Center(Head: Sangdo Park) and KAIST EEWS planning group. Prof. Cafer T. Yavuz and Prof. Ali Coskun said that “when Azo-COP is used for separation of CO2 and N2, the capturing efficiency has increased by hundred times.” He continued “This substance does not need any catalysts and has great chemical characteristics like water stability and structure stability so is expected to be used in various fields including carbon dioxides capturing” Meanwhile, this research is published in ‘Nature’s stablemate ‘Nature Communications’ on 15th of Jan.
