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.”

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.

Controlling DNA Orientation Using a Brush
Professor Dong Ki Yoon’s research team in the Graduate School of Nanoscience and Technology has developed a technique for producing periodic DNA zigzag structures using a common make-up brush.
The results of the research, first-authored by Ph.D. student Yun Jeong Cha and published in Advanced Materials (online, November 15, 2016), has been highlighted in the hot topics of “Liquid Crystals.”
There exist various methods for synthesizing DNA-based nanostructures, but they commonly involved complex design processes and required expensive DNA samples with regulated base sequences.
Using DNA materials extracted from salmon, the research team was able to produce a nanostructure with a well-aligned zigzag pattern at one-thousandth of the usual cost.
The team used a commercial make-up brush bought at a cosmetics store, and with it, applied the salmon DNA in one direction onto a plate, in the same way paint is brushed onto paper. Using a brush with a width of several centimeters, the team aligned DNA molecules of 2 nanometers in diameter along the direction of the brush strokes.
As the thin and dense film of DNA came into contact with air, it lost moisture. An expansive force was created between the dried film and the plate. This force interacted with the elastic force of DNA and caused undulations in the uni-directionally aligned DNA molecules, which resulted in a regular zigzag pattern.
The zigzag DNA’s base sequences could not be controlled because it was extracted from biological sources. However, it has the advantage of being cheap and readily available without compromising its structural integrity and provides a very regular and intricate structure.
This kind of well-ordered DNA structure can be used as template because it can guide or control versatile guest functional materials that are applied to its surface. For example, it can align liquid crystals used in displays, as well as metallic particles and semi-conductors. It is expected that this capacity can be extended to optoelectric devices in the future.
Professor Yoon remarked that “these findings have special implications, as they have demonstrated that various materials in nature aside from DNA, such as proteins, muscle cells, and components of bones can be applied to optoelectric devices.”
This research has been carried out with the support of the Korea National Research Foundation’s Nanomaterials Fundamental Technology Development Program and the Pioneer Research Center under the High-tech Convergence Technology Development Program.
