KAIST Joins IoF 2020 with 'Oliot'
KAIST will take part in the Internet of Food & Farm 2020 (IoF 2020) project with its international standard IoT open source platform ‘Oliot’ (Open Language for the Internet of Things, http://oliot.org), developed by a research team under Professor Daeyoung Kim from the School of Computing. Dr. Kim is also the director at the Auto-ID Labs at KAIST (http://autoidlabs.org). IoF 2020 is a project to provide solutions and facilitate the large-scale uptake of IoT by addressing the organizational and technological challenges the European farming and food sectors face today. The project will develop innovative IoT solutions by fostering co-creation in interactive improvement cycles focusing on user acceptability and business models to boost technology and market-readiness levels. Along with 71 partners from 16 countries, Professor Kim’s ‘Oliot’ will play a part in creating an ecosystem for providing safe and healthy agrifood, incorporating ICT(information and communications technologies) into the areas of smart farms and the agrifood service sector over the next four years. The project received €30 million in funding from Horizon 2020, the largest research and innovation program in the EU. KAIST is the only Korean institution to participate in this project. For the project, Professor Kim’s team will initially establish smart farm and food service testbeds for the domestic agrifood industry with ‘Oliot’ prior to connecting to the European one. Professor Kim said he will leverage Artificial Intelligence (AI) and deep learning in order to analyze the data collected from the ecosystems in the EU. He aims to open an integrated IoT platform system incorporated with AI technologies to serve governments, institutions, corporations, and farmers. It is expected that technologies developed for IoF 2020 will also benefit the domestic agrifood market and its supply chain infrastructure. Oliot will also be expected to further advance domestic smart industries including health care and connected vehicles. George Beers, project manager at Wageningen University & Research and the IoF 2020 project coordinator said, “IoF 2020 has the potential to transform the paradigm of the supply chain of agrifood from the farm to consumers’ dining tables. We believe this project will contribute to enhance European competitiveness and excellence in the food commerce industry.” Professor Kim said, “Technological applications of international standard IoT have already started in the domestic agrifood industry in collaboration with KAIST. We are working now with Asian and South American countries, as well as European nations, for the integration of a global agrifood business ecosystem.” Auto-ID Labs are a global research consortium of seven academic institutions that research and develop new technologies for advancing global commerce, partnering with GS1 (Global Standard 1), a non-profit organization that established standards for global commerce such as introducing barcodes to the retail industry. The Auto-ID Labs include MIT, University of Cambridge, Keio University, Fudan University, and ETH Zurich/University of St. Gallen as well as KAIST.

Adsorbent That Can Selectively Remove Water Contaminants
Professor Cafer T. Yavuz and his team at the Graduate School of Energy, Environment, Water, and Sustainability (EEWS) have developed an adsorbent that can selectively capture soluble organic contaminants in water. This water treatment adsorbent is a fluorine-based nanoporous polymer that can selectively remove water-soluble micromolecules. It has the added advantage of being cheap and easily synthesized, while also being renewable. The results of this research have been published online in Nature Communication on November 10, 2016. The research paper is titled “Charge-specific Size-dependent Separation of Water-soluble Organic Molecules by Fluorinated Nanoporous Networks.” (DOI: 10.1038/ncomms13377) Water pollution is accelerating as a result of global industrial development and warming. As new materials are produced and applied in the agricultural and industrial sectors, the types of contaminants expelled as sewage and waste water are also becoming diverse. Chemicals such as dyes and pesticides can be especially harmful because they are made up of small and highly soluble organic particles that cannot be completely removed during the water treatment process, ultimately ending up in our drinking water. The current conventional water treatment systems utilize processes such as activated carbon, ozonolysis, and reverse osmosis membrane. These processes, however, are designed to remove larger organic molecules with lower solubility, thus removal of very small molecules with high solubility is difficult. In addition, these micromolecules tend to be charged, therefore are less easily separated in aqueous form. The research team aimed to remove these small molecules using a new adsorbent technology. In order to remove aqueous organic molecular contaminants, the team needed an adsorbent that can adsorb micro-sized molecules. It also needed to introduce a chemical function that would allow it to selectively adsorb molecules, and lastly, the adsorbent needed to be structurally stable as it would be used underwater. The team subsequently developed an adsorbent of fluorine-based porous organic polymer that met all the conditions listed above. By controlling the size of the pores, this adsorbent is able to selectively adsorb aqueous micromolecules of less than 1-2 nm in size. In addition, in order to separate specific contaminants, there should be a chemical functionality, such as the ability to strongly interact with the target material. Fluorine, the most electronegative atom, interacts strongly with charged soluble organic molecules. The research team incorporated fluorine into an adsorbent, enabling it to separate charged organic molecules up to 8 times faster than neutral molecules. The adsorbent developed by Professor Yavuz’s team has wide industrial applications. It can be used in batch-adsorption tests, as well as in column separation for size- and charge-specific adsorption. Professor Yavuz stated that “the charge-selective properties displayed by fluorine has the potential to be applied in desalination or water treatment processes using membranes." This paper was first-authored by Dr. Jeehye Byun, and the research was funded by KAIST’s High Risk High Return Program and the Ministry of Science, ICT and Future Planning of Korea’s Mid-Career Researcher Program, as well as its Technology Development Program to Solve Climate Change.

Nobel Laureate Dr. John Michael Kosterlitz Speaks at KAIST
KAIST’s Department of Physics will invite one of three co-recipients of the Nobel Prize in Physics 2016, Professor John Michael Kosterlitz of Brown University, on January 9, 2017, to speak about the exotic states of matter, which is entitled “Topological Defects and Phase Transitions.” Professor Kosterlitz shares the Nobel award with two other researchers, David Thouless and Duncan Haldane. He is considered one of the pioneers in the field of topological phases. In the early 1970s, along with Thouless, he demonstrated that superconductivity could occur at low temperatures and explained the mechanism behind, phase transition, that makes superconductivity disappear at higher temperatures. Over the last decade, topological materials and their applications have been widely studied with the hope of using them in new generations of electronics and superconductors, or in future quantum computers. Details of the lecture follow below: Distinguished Lecture Series by KAIST’s Physics Department · Speaker: Professor John Michael Kosterlitz of the Physics Department, Brown University · Topic: “Topological Defects and Phase Transitions” · Date: January 9, 2017, 4:00 PM · Place: Lecture Hall (#1501), College of Natural Sciences (E6-2)

A KAIST Team Wins the Chem-E-Car Competition 2016
A KAIST team consisted of four students from the Department of Chemical and Biomolecular Engineering won the Chem-E-Car Competition 2016, which took place on November 13 at the Union Square in San Francisco. The students who participated were Young-Hyun Cha, Jin-Sol Shin, Dae-Seok Oh, and Wan-Tae Kim. Their adviser was Professor Doh Chang Lee of the same department. Established in 1999, the Chem-E-Car is an annual worldwide college competition for students majoring in chemical engineering. The American Institute of Chemical Engineers (AIChE), founded in 1908, is the world’s leading organization for chemical engineering professionals with more than 50,000 members from over 100 countries and hosts this competition every year. A total of 41 university teams including Carnegie Mellon University and Purdue University participated in this year’s competition. KAIST students competed in the event for the first time in 2014 and reached the rank of 28. In 2015, the students placed 16th, and finally, took the first place in last month’s competition, followed by the Georgia Institute of Technology. In the competition, students must design small-scale (20x30x40 cm) automobiles that operate chemically, as well as describe their research and drive their car a fixed distance down a wedge-shaped course to demonstrate the car’s capabilities. In addition to driving a specified distance (15-30 meters), the car must hold a payload of 0-500 mL of water. The organizers tell participants the exact distance and amount of payloads one hour before the competition begins. Winners are chosen based on their finishing time and how close their car reaches the finish line. Thus, students must show sophisticated coordination of chemical reactions to win. The KAIST team designed their car to have a stable power output using a Vanadium redox flow battery developed by Professor Hee Tak Kim of Chemical and Biomolecular Engineering. They employed iodine clock reactions to induce quick and precise chemical reactions to control their car. KAIST’s car finished with the best run coming within 11 cm of the target line; Georgia Tech’s car reached the finish line by 13 cm and New Jersey Institute of Technology’s car by 14 cm. Young-Hyun Cha, one of the four students, said, “When we first designed our car, we had to deal with many issues such as stalls or connection errors. We kept working on fixing these problems through trial and error, which eventually led us to success.” For a news article on KAIST’s win at 2016 Chemi-E-Car Competition by AIChE, see the link below: http://www.aiche.org/chenected/2016/11/koreas-kaist-wins-1st-place-2016-chem-e-car-competition-photos

Mystery of Biological Plastic Synthesis Machinery Unveiled
Plastics and other polymers are used every day. These polymers are mostly made from fossil resources by refining petrochemicals. On the other hand, many microorganisms naturally synthesize polyesters known as polyhydroxyalkanoates (PHAs) as distinct granules inside cells. PHAs are a family of microbial polyesters that have attracted much attention as biodegradable and biocompatible plastics and elastomers that can substitute petrochemical counterparts. There have been numerous papers and patents on gene cloning and metabolic engineering of PHA biosynthetic machineries, biochemical studies, and production of PHAs; simple Google search with “polyhydroxyalkanoates” yielded returns of 223,000 document pages. PHAs have always been considered amazing examples of biological polymer synthesis. It is astounding to see PHAs of 500 kDa to sometimes as high as 10,000 kDa can be synthesized in vivo by PHA synthase, the key polymerizing enzyme in PHA biosynthesis. They have attracted great interest in determining the crystal structure of PHA synthase over the last 30 years, but unfortunately without success. Thus, the characteristics and molecular mechanisms of PHA synthase were under a dark veil. In two papers published back-to-back in Biotechnology Journal online on November 30, 2016, a Korean research team led by Professor Kyung-Jin Kim at Kyungpook National University and Distinguished Professor Sang Yup Lee at the Korea Advanced Institute of Science and Technology (KAIST) described the crystal structure of PHA synthase from Ralstonia eutropha, the best studied bacterium for PHA production, and reported the structural basis for the detailed molecular mechanisms of PHA biosynthesis. The crystal structure has been deposited to Protein Data Bank in February 2016. After deciphering the crystal structure of the catalytic domain of PHA synthase, in addition to other structural studies on whole enzyme and related proteins, the research team also performed experiments to elucidate the mechanisms of the enzyme reaction, validating detailed structures, enzyme engineering, and also N-terminal domain studies among others. Through several biochemical studies based on crystal structure, the authors show that PHA synthase exists as a dimer and is divided into two distinct domains, the N-terminal domain (RePhaC1ND) and the C-terminal domain (RePhaC1CD). The RePhaC1CD catalyzes the polymerization reaction via a non-processive ping-pong mechanism using a Cys-His-Asp catalytic triad. The two catalytic sites of the RePhaC1CD dimer are positioned 33.4 Å apart, suggesting that the polymerization reaction occurs independently at each site. This study also presents the structure-based mechanisms for substrate specificities of various PHA synthases from different classes. Professor Sang Yup Lee, who has worked on this topic for more than 20 years, said, “The results and information presented in these two papers have long been awaited not only in the PHA community, but also metabolic engineering, bacteriology/microbiology, and in general biological sciences communities. The structural information on PHA synthase together with the recently deciphered reaction mechanisms will be valuable for understanding the detailed mechanisms of biosynthesizing this important energy/redox storage material, and also for the rational engineering of PHA synthases to produce designer bioplastics from various monomers more efficiently.” Indeed, these two papers published in Biotechnology Journal finally reveal the 30-year mystery of machinery of biological polyester synthesis, and will serve as the essential compass in creating designer and more efficient bioplastic machineries.
