A research team led by Profs. Kim Jong-hyun and Kwon Oh-pil has successfully developed a high-performance gas sensor using an organic semiconductor. This will boost the electrical and optical gas detection capability of organic semiconductors and is expected to be utilized as a next-generation, high-sensitivity sensor to detect toxic gases.Profs. Kim Jong-hyun and Kwon Oh-pil (Department of Applied Chemistry & Biological Engineering and Graduate School of Molecular Science and Technology) and a research team at the Ulsan National Institute of Science and Technology (UNIST) School of Energy and Chemical Engineering (ECHE) jointly announced development of the gas-detecting sensor.Related research was published in the online edition of Advanced Functional Materials (IF: 18.808) an international journal in materials, under the title, “Strategic Approach for Enhancing Sensitivity of Ammonia Gas Detection: Molecular Design Rule and Morphology Optimization for Stable Radical Anion Formation of Rylene Diimide Semiconductors” on July 27, 2021.Profs. Kim Jong-hyun (photo left) and Kwon Oh-pil (photo right) of Ajou University and Prof. Sang-kyu Kwak of UNIST took part in the research as corresponding authors, while Oh Byoung-min and Park Seong-ha, students at Ajou University Graduate School Department of Molecular Science & Technology, took part as first authors.Ammonia (NH3) gas, a volatile organic compound, is a highly toxic chemical. Inhalation of high concentrations for long periods of time can result in headache, nausea, coughing, difficulty breathing, and other reactions. A variety of studies have been carried out on the development of high precision detection technology due to the change in resistance of semiconductor materials. However, conventional inorganic semiconductors involve highly complicated manufacturing process, rendering elements of the sensors as very expensive. In contrast, organic semiconductor materials are limited in terms of detection function and detection selectivity.The research team focused on ammonia gas and the organic semiconductor material based on rylene, which can selectively formulate stable radical anion. It discovered that when rylene-structured organic semiconductor material is exposed to ammonia gas, the intramolecular transfer charge reaction formulates stable radical anion and results in amplified electric current value and changes in light absorption. The research team utilized this to develop a high-performance gas sensor that can detect amounts of ammonia gas as tiny as 200ppb (parts per billion), while at the same time amplifying electric current to 1700% from ammonia gas.The research team also verified the principle of efficient charge transfer reaction that occurs between ammonia gas molecules and rylene organic semiconductor molecules using quantum computation and also proposed the principles of sensor and material design. “The organic semiconductor material proposed in this study has a very simple combination process and even the tiniest amount of ammonia gas can create an amplified electric current signal through radical anion reaction,” said Prof. Kim. “This will allow us to overcome cost and detection limitations, which are issues in conventional gas sensors, and resolve the related problems.” He added, “The material we have developed will enable the development of high-sensitivity ammonia gas sensors that are also competitively priced.”This research project was sponsored by the National Research Foundation (NRF) Research Facility Establishment Program (Molecular Science & Technology Research Center (MSTRC)), Basic Research in Science and Engineering (Mid-Career Researcher Program), and the International Cooperation and Leading Research Center Program (Functional Crystallization Center). <Principle of stable radical anion formation using rylene organic semiconductors and performance of high-sensitivity ammonia gas sensor using this principle><July 27, 2021 online issue of Advanced Functional Materials >

Ajou University has transferred color-changing technology to detect hydrogen leakage to a company in a related field. The technology will create significant momentum in the hydrogen economy and safety.This technology was developed by a research team led by Prof. Seo Hyung-tak, and through a technology transfer agreement, generated more than KRW 2.5 billion in income. This is the largest technology transfer project in the non-bio sector for Ajou University since the university’s establishment.The technology transfer agreement ceremony held in Yulgok Hall on July 27, 2021 was attended by Ajou University’s President Park Hyung-ju, CEO of Daehyun ST Co., Ltd. Eom Ju-heung, Prof. Seo (Dept. of Materials Science and Engineering, Graduate School Department of Energy Systems Research) of Ajou University, and other participants from both institutions.This color-changing technology is a high-performance, high-precision sensor that can measure hydrogen concentrations with great precision, which is essential to safety in the use of hydrogen. Highlighted as a next-generation green fuel source, hydrogen is increasingly being applied to new industrial sectors. However, safety issues arising from its properties have always been a stumbling block. Since hydrogen has no color, is odorless and light weight, the risk of undetected leakage is high, and can result in combustion.This sensor technology is comprised of a liquid combination method and semi-conductor deposition method allowing multi-angle sensor processes to be constructed and customized for different purposes and mass production in various application fields.Existing conventional hydrogen detection requires a power supply, which can lead to hydrogen combustion from static electricity, and can only be installed in limited places. This new sensor is gaining wide recognition as a distinct technology in hydrogen leak detection as it primarily uses a chemical color-changing method, which enables the intuitive identification of hydrogen leaks at the starting point (without power supply). It also involves a multi-detection method which uses electrical signals for remote monitoring.The research team has also acquired numerous patents in source material technology for the hydrogen sensor to enhance its reliability. One of the original technologies it developed is nano material protection layers to increase material reliability, which is an issue with today’s hydrogen sensors.Daehyun ST plans to utilize this technology to offer hydrogen sensors to hydrogen charging stations and hydrogen automobiles. Building from this base, Daehyun ST expects to increase sales revenues not only in the domestic market but also overseas, including in Germany, Japan, and the United States.The transferred technology is particularly significant because it is a base technology fundamental to the Act on the Promotion of Hydrogen Economy and Hydrogen Safety Management (“Hydrogen Safety Act”), which will come into effect in February 2022. The Hydrogen Safety Act legally institutionalizes a hydrogen safety device for systemic promotion and safety management of the hydrogen industry. With this, Ajou University has secured a foothold to position itself as a pioneering institution in cutting-edge technology.Ajou University recorded earnings of KRW 3.35 billion from last year’s technology transfers, ranking seventh among universities nationwide. Earnings from technology transfers have been rising for five years. This is an amount paid by a company seeking to utilize the R&D results by an Ajou University research team and to acquire the relevant intellectual property rights. It is a major source of revenue from industry-academia cooperation and an indicator of the university’s leading research capacity. Ajou University operates a technology commercialization process for all periodic cycles that enables the results of its research teams to be widely utilized by businesses and society. It is committed to the commercialization of technology. Prof. Seo’s research team built the foundation for successful commercialization of this technology, and was selected for the Project to Support Mid & Large-scale Growth of the Research Industry under the Commercializations Promotion Agency for R&D Outcomes, itself under the Ministry of Science and ICT.* Photo: From left, Eom Ju-heung, CEO of Daehyun ST Co., Ltd., Prof. Seo Hyung-tak and President Park Hyung-ju of Ajou University.

A joint research team from Ajou University has developed a catalyst response technology that can produce hydrogen and carbon using methane, the main component of city gas, or natural gas. This is a cutting-edge energy technology that can concurrently mass produce green, affordable hydrogen fuel and high purity, high value-added carbon.The joint research team, led by Prof. Seo Hyung-tak (Dept. of Materials Science and Engineering, Graduate School Department of Energy Systems Research) and Prof. Kim Yu-kwon (Chemistry, Graduate School Department of Energy Systems Research) announced the development of technology to produce hydrogen gas and solid carbon directly converted from methane using a bubble column reactor injected with molten liquid alloy catalysts and zirconia. Their achievement was published in the online edition of Chemical Engineering Journal (IF=13.273) on July 7, 2021 under the title, “Enhanced Efficiency in CO2-free Hydrogen Production from Methane in a Molten Liquid Alloy Bubble Column Reactor with Zirconia Beads.” Lee Young-jae, a doctoral student at Ajou University, and Dr. Noh Yong-gyu took part as first co-authors, and another doctoral student, Kim Jin-a, and Prof. Shankara Kalanur also joined.Hydrogen, a clean fuel that emits water after use, has recently gained recognition as a next-generation energy source and is increasingly applied to diverse industrial fields. Mass production of hydrogen as fuel is commonly achieved by reforming fossil fuels, but the process emits CO2 that is nine times greater than the weight of hydrogen thereby produced.Due to this and other reasons, research has recently been active in photoelectrochemical water splitting technology using electricity or solar energy towards reducing emission of CO2, a major greenhouse gas. However, barriers have existed to these efforts as the unit cost of production has been at least five to six times the cost of reforming fossil fuels, and it could not be mass produced. Therefore, development of a way to mass produce hydrogen in an affordable and CO2-free manner is urgently needed if we are to realize a hydrogen economy, with hydrogen energy as a completely clean fuel.The Ajou University research team focused on methane gas (CH4), a major component in city and natural gas. When methane gas undergoes a pyrolysis process using solid catalysts at temperatures greater than 1000℃, it produces hydrogen gas and solid carbon. The solid carbon thereby produced could not be commercialized previously as it becomes deactivated. When solid carbon accumulates on the surface of the catalyst, it ultimately prevents the chemical reaction of methane gas there, as a result of which its reaction activity rapidly disappears.To address this limitation, researchers have recently turned their attention to the use of low-melting liquid metal (LM) alloy catalysts (liquid metal catalyst combining low-melting metals, such as tin, and high-melting metals, such as nickel, which are high catalyst activation). In other words, direct molten catalyst methane conversion technology injects methane gas into molten liquid metal alloy to produce hydrogen. At the same time, flotation and reaction are maintained due to the difference in carbon layer density on the surface of the liquid catalyst while also producing solid carbon.The joint research team developed a new method, based on this direct molten catalyst methane conversion technology, to discover that maximizing the surface area of the boundary between methane gas and liquid catalyst by reducing the residence time of methane gas inside the liquid catalyst and size of the methane gas bubble in the methane decomposition reaction using liquid catalysts is a critical factor in enhancing reaction efficiency. The research team developed a new reactor structure by additionally injecting zirconia (a mixture of zirconium and oxygen (ZrO2) which has a high melting point, is not easily decomposed, and is in a white crystalline form at room temperature) to the liquid catalyst in the reactor to minimize the size of the methane bubble and complicate the gas flow channel, which increased gas residence time.The adoption of a new reactor structure resulted in a high hydrogen conversion rate (about 37% methane at 985℃, lower than the existing temperature of at least 1000℃), and strong reaction durability as catalyst activity increased even after a long production period of more than 150 hours. In general, methane thermal decomposition reaction at 1000℃ or lower lowers the cost of thermal energy in accordance with reactor quality, but it also resulted in a rapid decrease in conversion rate. The Ajou research team overcame this stumbling block to record the highest conversion rate and continuous reaction at low temperature. The carbon produced using this new method was in a form that is high purity and high value-added (carbon nanotube and fiber filament). Such carbon can be used in batteries and fuel cells. This new development taps into the potential not only for environmentally-friendly mass production of hydrogen but also high-applicability carbon materials.“The existing hydrogen production methods using fossil fuels will inevitably undergo a rise in price due to trends toward stronger regulations on CO2 emissions,” said Prof. Seo. “This research is significant in that it has opened up a new green and affordable path of mass production of hydrogen.”He also added, “It can be remarkably economical if the carbon produced simultaneously and continuously with hydrogen is of high purity and has high value-added properties. We will continue our research and aim for its commercialization.” The research was sponsored by the Industrial Technology Alchemist Project managed by the Korean Ministry of Trade, Industry, and Energy (MOTIE), Korea Evaluation Institute of Industrial Technology (KEIT) and C1 Gas Refinery R&D Center managed by the Korean Ministry of Science and ICT and the National Research Foundation of Korea (NRF).This is a concept diagram of the production of hydrogen and carbon using direct methane decomposition based on molten liquid alloy catalysts: when methane is injected into the reactor, which is mixed with liquid metal alloy catalyst and zirconia, and heated, high purity hydrogen forms inside the liquid catalyst, while at the same time creating carbon fiber. Carbon fiber is of low density and will float to the surface. This is why it is not affected by the catalytic reaction and long hours of continuous production of hydrogen and carbon are possible.*PhotoFrom far left: Prof. Seo Hyung-tak, PhD students Lee Young-jae and Park Jin-a, and Prof. Kim Yu-kwon

An Ajou University research team under Professor Kim Jong-hyun has been selected by the Ministry of Science and ICT (MSIT) to participate in the Korea-Australia Strategic International Joint Research Project. Professor Kim Jong-hyun (Department of Applied Chemistry and Biological Engineering/ Graduate School of Molecular Science and Technology) announced that his team will participate in the Korea-Australia Strategic International Joint Research Project together with Professor Jan Seidel’s team from the University of New South Wales’ (UNSW) Department of Materials Science and Engineering with the aim of developing an IoT-integrated independent sensor module for AI-powered diagnosis of livestock disease. The project period is two years (2021-2023) and will have an expected KRW 1 billion in project expenses.The MSIT has been leading the Strategic International Joint Research Project with an aim to address technological gaps and secure advanced technology through strategic international cooperation, with a view towards the impact of the Fourth Industrial Revolution and the technological abilities of research counterparts with the common goals of addressing climate change, micro dust, infectious disease, and other global challenges. The joint research team plans to develop an independently-run IoT sensor module that monitors the health of livestock in real time to diagnose and forecast pathogenesis, and create data mining analysis-friendly solutions for livestock diseases.A sensor module, which is the development goal of this project, will be designed around an independent power system which does not require replacing batteries and enables detection of various conditions of livestock health at the same time. Accordingly, it is expected to significantly reduce livestock management costs for Australian cattle ranchers as the country has a very large number of grazing livestock. The two countries’ research teams plan to lead studies focusing on their specialized fields. Professor Kim Jong-hyun’s team will develop an IoT-integrated independently-operated sensor module, while the Australian team will optimize a sensor module for localization and analysis of livestock health data. Narromine, a town in Australia, will provide the town’s livestock data as a test bed for the project so that the sensor module, the outcome of the project, can be adopted by the local agro-livestock industry. Professor Kim, who is heading the project, stated “Our team has secured advanced technology through continuous research collaboration with the Australian team,” and added, “Based on such collaboration, the bilateral project will enable us to successfully develop an IoT sensor module for diagnosis of livestock disease.” In addition, Kim said, “Australia is home to the world’s largest livestock headcount in a variety of species combinations, and is therefore very interested in the project. […] Our team has completed the first verification test of a neckband-type sensor module that we developed early on, and is currently discussing management authority of the final product with an Australian company.”Aside from joint technological development, which is the primary goal of the joint research project, Kim’s team plans to strengthen international cooperation and professional training by promoting active exchange of students and researchers between Ajou University and UNSW.In addition to Ajou University and UNSW, other involved institutions include the Korea Institute of Materials Science, the Korea Electronics Technology Institute, Pusan National University, Charles Stuart University of Australia, and the town of Narromine.인공지능 기반 가축질병 진단 IoT 통합형 독립구동 센서모듈 개발Developing an IoT-Integrated Independently-Operated Sensor Module for AI-Powered Diagnosis of Livestock Disease기존기술Existing Technology교체형 배터리 기반의 센서Sensors based on battery swap system사람에 의한 가축질병 진단Diagnosis of livestock disease done by humans자율전원 및 진단Autonomous power system and diagnosis제안기술(차별성)Proposed Technology (Differentiation)배터리 자율전원 IoT 디바이스 센서 모듈Autonomous battery-powered IoT device sensor module실내외 현장 적용가능Application possible inside or out자율전원 모듈Autonomous power module가축진단 데이터 구축Construction of livestock diagnosis data멀티 빅데이터 구축 가능Possible to construct multi-sourcebig data 전용, 진단Dedicated, diagnostic

Professors Kim Wook and Yang Si-young’s team confirmed the osteoarthritis treatment mechanism of globular-shaped self-assembled hyaluronic acid nanoparticles. The recent finding is expected to contribute to improving in vivo safety and efficacy of linear hyaluronic acids used in chondroprotective agents for osteoarthritis. Professor Kim Wook (Department of Applied Chemistry & Biological Engineering, left in photo) and professor Yang Si-young (School of Medicine, right in photo) of Ajou University announced that the team has confirmed the chondroprotective efficacy of globular-shaped self-assembled hyaluronic acid nanoparticles and inflammation relief action. This means that target-specific drug carriers can become a potential therapeutic agent for osteoarthritis treatment.The study has been published in Biomaterials (IF 10.317), an international journal exploring the science of biomaterials and their translation towards clinical use, on June 19th with the title, “Self-Assembled Hyaluronic Acid Nanoparticles for Osteoarthritis Treatment.”The number of osteoarthritis patients continues to rise globally as lifespans have continued to lengthen, bringing to population aging. However, injection-type high-molecular-weight hyaluronic acids currently used in drugs and chondroprotective agents are not stable within a living body. The research team focused on self-assembled hyaluronic acid nanoparticles which are mainly used as in-vivo friendly, non-toxic, target-specific and long-acting drug carriers. As compressed globular-shaped self-assembled hyaluronic acid nanoparticles are relatively safer in vivo than linear hyaluronic acids, the team assumed that they are long-standing and provide increased inflammation relief. Accordingly, the team injected self-assembled hyaluronic acid nanoparticles into the knee joint of mouse models and observed through a multiphoton confocal microscope that the nanoparticles that penetrated the cartilage cell membrane conjugated with CD44 receptors and protected joint cartilage against osteoarthritis progression.This is evidence that multiple CD44-binding sites of nanoparticles conjugate with multiple CD44s at the same time, creating CD44 clustering in the cell membrane which effectively inhibits CD44 expression. The research team further explained that the drug carrier—self-assembled hyaluronic acid nanoparticles—itself, without any drug load inside, can inhibit CD44 receptors which aggravate joint cartilage erosion.In addition, the team reaffirmed that CD44 receptors can be a target for developing osteoarthritis treatments. CD44-deficient mouse models showed significantly lower osteoarthritis development compared to the control group with CD44 expression even when artificially inducing osteoarthritis in knee joints. The latest study suggests potential use of self-assembled hyaluronic acid nanoparticles as osteoarthritis treatments that interact with CD44. This recent finding is very meaningful as it provides a clue to overcoming the limitations of current linear hyaluronic acids and their low stability and inflammation-inducing effects due to product degradations.The study was sponsored by the Ministry of Science and ICT and the National Research Foundation of Korea as part of their Middle-grade Research Program and Bio/Medical Technology Development Program.<Self-Assembled Hyaluronic Acid Nanoparticles for Osteoarthritis Treatment Mechanism>

Ajou University has been selected as one of Korea’s top 5 in THE Young University Rankings, along with KAIST, POSTECH, UNIST and GIST.The UK’s Times Higher Education (THE) lists the world’s best universities that are no more than 50 years old. In this year’s THE Young University Rankings, Ajou University ranked 152nd internationally and 5th domestically. Ajou University has moved up more than 50 ranks from last year (201st~250th). This year’s improvement is very meaningful as it came amid a growing number of universities participating in THE Young University Rankings. Improving its overall evaluation scores ranging from education conditions, research, paper citations, globalization and industry-academia cooperation has been instrumental in driving this improvement. The UK university evaluation institution THE announced its 2021 THE Young University Rankings on June 23rd with results of its evaluation of 475 international universities under 50 years of age. THE has been publishing the rankings since 2010 using indicators such as ▲education conditions (30%) ▲research results (30%) ▲paper citations (30%) ▲globalization (7.5%) and ▲industry-academia cooperation (2.5%). Nanyang Technological University (NTU) tops the global ranking of the best young universities followed by France’s PSL (2nd) and the Hong Kong University of Science and Technology(3rd). Global rankings of Korea universities include KAIST in 4th place and POSTECH and UNIST in 8th and 10th place respectively. Ajou University has made a variety of efforts to attract talented faculty and strengthen its research capabilities. The university has established a new “Best Paper Awards” which awards its professors according to qualitative evaluations of their papers and expanded its settlement research expenses for newly-hired professors. For instance, newly-hired professors at Ajou University in science and engineering are entitled to receive a maximum of KRW 100 million in research grants, while those in the humanities and social sciences are entitled to a maximum of KRW 50 million. The period of eligibility for this research grant, spanning receipt of the grant to the submission of results, has been extended from three years to four. To improve its research capability, Ajou has subsidized research expenses of post-doctorate researchers and actively invited outstanding research experts through its participation in international symposiums. Efforts like this have resulted in the university earning KRW 3.35 billion in technology transfer revenues last year. These proceeds come from industry-academia cooperation projects and are an indicator that signifies research strength. Ajou University’s proceeds have been on the rise for the past five consecutive years. Technology transfer revenue proceeds refer to money paid by companies to the university in exchange for acquiring intellectual property towards using the outcomes of research by university research teams. Ajou University has been seeing continuous good results in many university rankings announced by global university rating institutions. It ranked in the 531st-540th group by the QS World University Rankings, representing 3 consecutive years of improvement, published in early June this year and 130th in THE Asia University Rankings 2021—representing a move up 49 places from last year. In addition, Ajou ranked in the 201st-300th group in THE Impact Rankings 2021, moving over 100 places up year-on-year. THE Impact Rankings look into social responsibility activities at each university, centered around the UN Sustainable Development Goals (SDGs).

Professor Lee Jung-ho’s Team from Ajou University’s Department of Mechanical Engineering has been selected as a lead research team for the 1st Energy Technology Development Project launched in 2021 by the Ministry of Trade, Industry and Energy (MOTIE). The MOTIE is leading around 80 projects in the fields of new and renewable energy, energy-related new industry, clean thermal and nuclear power plant, smart grid, and public R&D in order to realize a carbon neutral society and promote technology development for Green New Deal projects that will enable the country to respond to changes in energy environment. A total of KRW 195 billion will be shared amongst 119 projects. Professor Lee Jung-ho (left in photo) has been selected to lead a project on core technology and module development to improve the performance of heat pipe heat exchangers using a boiling model, which Lee’s team applied for within the category of “Projects related to technology development for energy demand management.” The project timeline is from May 2021 to December 2025 and is projected to cost KRW 13.5 billion.A heat exchanger transfers heat from a region of higher temperature to one of lower temperature through a heat pipe—a very high thermal conductance device which does not consume any external energy. The device structure is simple and is not easily deformed by heat, lending it to use as a heat exchanger for recovery of waste heat and cooling/heat exchange systems in the aerospace industry.Professor Lee Jung-ho’s team (right in photo) plans to develop a boiling pipe heat exchanger. A boiling pipe uses ‘boiling’ heat transfer technology which surpasses the performance of existing heat exchangers, dependent as they are on evaporation. The new heat transfer technology is gaining a lot of traction as a core technology for advanced management of heat from high heat sources such as cooling devices for power semiconductors, electric vehicles, energy storage systems (ESSs) and laser-guided munitions.The team aims to contribute to reducing greenhouse gas emissions and lower energy costs of power plants, boilers, incinerators, etc. It expects to add value by cutting the indirect energy waste in waste heat recovery by small and medium-sized companies.Lee Jung-ho, who heads the project, was appointed in March 2021 as professor in the Department of Mechanical Engineering. He is one of the top Korean experts in advanced insulation and heat management technology, and has developed heat system insulation technology and heat management technology over the past 25 years.Leading institutions participating in this project led by Ajou University include Korea Institute of Machinery and Materials, Chungang University Industry Academic Cooperation Foundation, Ulsan National Institute of Science and Technology (UNIST), Korea Advanced Institute for Science and Technology (KAIST), and Uniwel Corporation.<Overview of a Boiling Pipe Heat Exchanger>히트파이프(증발/막응축)Heat Pipe (Evaporation/Filmwise Condensation)비등파이프(비등/적응축): 상변화 열전달 촉진Boiling Pipe (Boiling/Dropwise Condensation): Enhancing phase change heat transfer히트파이프: 파이프 내부 증발과 막응축을 이용한 열교환Heat Pipe: Heat exchange through evaporation and filmwise condensation inside pipe비등파이트: 파이프 내부 비등과 적응축을 이용한 열교환Boiling Pipe: Heat exchange through boiling and dropwise condensation inside pipe열교환기 효율 양상에 따른 Compact 구현Creating a compact module by enhancing heat exchanger efficiency
