A team of Ajou scientists has developed a near infrared ray (NIR) photodetector capable of detecting deterioration and damage in human muscle structures. The new device is expected to have many applications, including medical imaging equipment that requires highly sensitive and efficient sensors.The team, led by (Dept. of Materials Science and Engineering / Graduate Dept. of Energy Systems, pictured), has developed a new image sensing device using alternating current photovoltaic effects, which offer high detectivity and rapid rise/decay time. The development was introduced in an article entitled, “Broadband alternating current photovoltaic effect: An application for high-performance sensing and imaging body aches” in the August 29 online issue of Nano Energy (IF = 16.602). The team includes Prof. Park Ji-yong yong (Dept. of Physics / Graduate Dept. of Energy Systems Research), Prof. Kim Sang-wan (Dept. of Electrical and Computer Engineering), and Dr. Mohit Kumar (first author).Photodetectors, which convert light into electric signals, have so far been associated with solar energy cells. But these devices have much broader application, as they are essential not only in new and renewable energy, but also smartphones, the Internet of Things (IoT), and optical communications. Lately, there has also been growing interest in developing medical applications as well, as photodetectors can help make diagnosis and ongoing monitoring of patients far easier. Industries and academia alike have been particularly interested in photodetector technology that can facilitate the imaging of damage to muscles inside the human body. Photodetectors are already being used in assessing patients with advanced-degree burns.Photodetector researchers, in turn, have been paying attention to NIRs, as they are expected to minimize further damage to the body by light and enable the detector to sense at greater depths of internal tissues and organs. As a result, there has been great demand for high-performance photodetectors capable of detecting even the slightest changes in NIR signals. Such photodetectors would also have to be highly energy-efficient to be installed on portable medical diagnostic devices.Compound semiconductors have been the typical choice for NIR-based photodetectors so far. These compound semiconductors, including gallium-arsenic, however, are quite expensive, have low levels of detectivity in the NIR range, and have not performed well thus far. Most critically, they fail to have the high level of detectivity necessary for medical devices to identify and image damage inside the human body.Prof. Seo’s team has sought to overcome this by laying a quality titanium oxide (TiO2) nanofilm onto a silicone (Si) substrate and controlling the surface characteristics. The researchers have also succeeded in developing a photodetector structure that maximizes optical responsivity using silver nanorays. As a result, the team was able to create a high-performance photodetector promising a much higher switching ratio (≈1E4), detectivity (≈1E11 Jones), and response time (~ 120 μs) than available today. The resulting photodetector is superior in all areas of performance over the NIR photodetectors available today.The alternating photovoltaic current enables the photodetector to generate energy from the rapidly flickering incident rays on its own, eliminating the need to connect it to an outside power source. The photodetector, moreover, generates photovoltaic currents that are nearly 39,000 times greater than direct photovoltaic currents typical of solar cells, making it very well-suited to medical imaging.Prof. Seo’s team has also identified the operating mechanism of the photodetector using Kelvin probe force and electrostatic force microscopy. The alternating incident rays generate inhomogeneous absorption-induced imbalanced carriers inside the semiconductor. The resulting quasi-Fermi level splitting and realignment, the researchers demonstrated, ensures fast response and high detectivity by the photodetector.Prof. Seo: “We successfully imaged internal changes in the muscular tissues of the fingers by scan-imaging them with our photodetector.” He explained, “With this device, we will be able to detect [the locations of] body aches and pain and image them at ultra-high speed. We expect the photodetector will be applied to scanning and diagnosing various other types of changes occurring not just in muscles, but in other parts of the body as well, particularly for pediatric patients.”The team’s research project was made possible in part thanks to the Program for the Future New Material and Original Technology Development Program and the Basic Research Support Program for Experienced Researchers, both from the Ministry of Science and ICT and the National Research Foundation of Korea. A patent application on the invention is now pending.

A team of researchers including Ajou’s own Prof. Hwang Jon-kook (Department of Chemical Engineering) has developed a new original technology for controlling the shapes of porous nanomaterials. The team’s discovery is expected to help solve current roadblocks to innovation in various fields, including secondary cells and energy storage systems, as well as energy, catalysts, environmental engineering, and medicine.The article, listing Prof. Hwang as the principal author, was published in the August 12 online issue of Science Advances (IF = 13.116, JCR 4.93%), a sister publication of Science. Dr. Kim Seong-seop and Prof. Lee Jin-woo of the Korea Advanced Institute of Science and Technology (KAIST) were also on the team.The title of the article reads: “Polymer blend directed anisotropic self-assembly toward mesoporous inorganic bowls and nanosheets.”The team has developed a new mechanism which can easily control the shapes of molecules and nanostructures by simply combining and heating an organic polymer blend and an inorganic metal oxide precursor. Furthermore, the team demonstrated that the dish-shaped niobium oxide created by applying their method offers the highest-possible levels of performance and safety when used as an anode for a potassium ion battery, which garners attention as a potential material for next-generation secondary batteries.Researchers worldwide have so far sought to control the shapes of porous materials through complex and often expensive methods. These methods, however, failed to ensure precise and efficient control of porous nanostructures and particles. Accordingly, there has been growing demand for a new technique that is simpler, less expensive, and more capable of controlling all relevant factors, including size, structure and shape of pores.Prof. Hwang’s team found a solution in the self-assembly effect of multicomponent polymer blends. Multicomponent polymer blends can assemble themselves into complex and sophisticated nanostructures when certain conditions are met. Although this mechanism has long been known in polymer physics, few actual applications have been made out of it.Prof. Hwang’s team established a design guideline that brings together the self-assembly mechanism of multicomponent polymer blends with inorganic material chemistry, and the result—the anisotropically self-assembled particle (ASAP)—was thus born, promising simple and easy ways to control nanostructure, chemical composition and shape of porous materials.Prof. Hwang explains: “Our work is significant in that it demonstrates, for the first time, that self-assembling polymer blends can be used to solve the problem with synthesizing porous inorganic materials.” He adds, “This means that we can now pioneer new fields of interdisciplinary research that connect polymer physics and inorganic material chemistry.”As a nanoenergy and material specialist, Prof. Hwang has long been researching ways to control the structures and shapes of porous nanomaterials. His future research plans include finding simple methods for synthesizing inorganic porous materials and producing customized designs for electrodes of next-generation secondary batteries.*Pictured: A diagram of ASAP, a porous inorganic material using the self-assembly of a multicomponent polymer blend.

A team of researchers with the participation of Ajou Professor Park Dae-chan (Department of Biological Sciences) has found a new clue to preventing disruptions to the placenta, vital to fetal growth and nutrition. The team’s discovery of a new factor critical to placental development is expected to catalyze development of new solutions to ensure early fetal health.The team’s article, published in the July 31 online issue of Nucleic Acids Research (Impact factor: 11.501, IF% = 4.882), was entitled, “The chromatin-binding protein PHF6 functions as an E3 ubiquitin ligase of H2BK120 via H2BK12Ac recognition for activation of tophectoderman genes.” The team also included Prof. Baek Sung-hee of Seoul National University and Prof. Lee Ji-min of Kangwon National University.The team discovered the importance of an epigenetic factor known as PHF6 in the trophectoderm of the blastocyst in placental formation. Blastocysts are sphere-shaped bundles of cells that contain embryonic stem cells, surrounded by trophectoderms. Trophectoderms form the embryo and the placenta, and how epigenetic factors regulate trophectodermal differentiation has not been understood until now.Based on an mRNA-sequencing genomic analysis, an emerging method for analyzing nucleic sequences, Prof. Park’s team discovered that embryonic stem cells from which PHF6 was removed led to disruptions in the formation of blastocysts and the placenta.PHF6 is an epigenetic factor protein that recognizes histone modifications. The team found that PHF6, by recognizing the chemical modifications (acetyl group) to histone proteins surrounding DNA, additionally binds ubiquitin to the histone. In other words, the researchers confirmed that histone modifications by PHF6 is what regulates the expression of trophectodermal genes in blastocysts.The team explained: “We have demonstrated that it is possible to modify the placental developmental process epigenetically using histone proteins that are dissolved and resynthesized in just days, instead of modifying the DNA nucleic sequences transmitted down the generations.”The research was made possible with the help of the Ministry of Science and ICT (MSIT) and the National Research Foundation of Korea (NRF)’s Leading Research Support, Individual Basic Science and Engineering Research, and New Researcher Support Programs.

A cover image of Chemical Reviews. ©ACS Publications.An article by a team of international researchers, which included Professor Kwak Won-jin (Department of Chemistry/Department of Energy System Research (Graduate)), was published as the cover article for the July 22 online issue of Chemical Reviews.The article, for which Prof. Kwak is a principal author, concerns lithium-oxygen batteries, a next-generation secondary battery system garnering attention worldwide. The team of researchers included Prof. Sun Yang-kook of Hanyang University, Korea; Prof. Doron Aurbach of Bar-Ilan University, Israel; Prof. Peter Bruce of the University of Oxford; and Prof. Linda Nazar of Waterloo University, Canada. Chemical Reviews, published by the American Chemical Society (ACS), is the top-ranked journal in the entire field of chemistry.In the article entitled “Lithium-Oxygen Batteries and Related Systems: Potential, Status, and Future,” Prof. Kwak and his colleagues introduce the findings of their years-long research into the structure of the lithium-oxygen battery, its working mechanism, and related derivative systems. The researchers also discuss the core issues and recent trends in research on the lithium-oxygen battery, and needed practical improvements.A next-generation secondary battery system capable of utilizing oxygen in the air as fuel, the lithium-oxygen battery holds the potential to surpass the theoretical energy density limit of the lithium ion battery used in electric vehicles. Research has abounded on the topic as a result, but there are also considerable obstacles that compromise its commercial viability, such as its short lifecycle as a side effect of reacting with oxygen, its low energy efficiency due to the inevitable creation and dissolution of byproducts. Innovative solutions to these problems are needed.Prof. Kwak explains: “It is exceedingly difficult to improve the lithium oxygen battery’s energy efficiency and reversibility to a viable level, as there are a number of complex factors involved,” adding, “But, insofar as the demand for high-energy-density battery systems continues to grow, we should continue rising to the challenge.”Prof. Kwak will continue his research on the lithium oxygen battery in his new faculty position in the Department of Chemistry at 鶹Ӱ, where he was appointed in the spring semester. He has published a number of articles in this year, addressing issues with the lithium oxygen battery and possible solutions.

* Self-powered wearable module for diagnosing livestock health, developed by a team of Korean and Australian researchers* Joint research by Korean and Australian researchersA team of researchers led by Professor Kim Jong-hyun (Department of Applied Chemistry and Biological Engineering/Graduate Department of Molecular Science and Technology), working together with a team of Australian researchers, succeeded in developing the core technology for a self-powered wearable module for diagnosing livestock health. The technology is expected to aid in the development of a cutting-edge digital platform that allows large livestock farmers to diagnose and manage the health of their livestock in real time.The results of the research collaboration, entitled “Investigation of Low-intensity Light Performance of Kesterite CZTSe, CZTSSe, and CZTS Thin-film Solar Cells for Indoor Applications,” were published on the online issue of Journal of Materials Chemistry A (IF = 11.301, JCR top 6.7%) on July 21. The authors include researchers from 鶹Ӱ, the Green Energy Institute, Chonnam National University, and the University of New South Wales.The researchers discovered the mechanism of a CZTSSe-based solar cell that can be used in a variety of low-light settings. CZTS-based thin-film solar cells are affordable and eco-friendly light absorbers, and are expected to lead to the development of a better alternative to existing solar cells, which are expensive and made of environmentally harmful heavy metals. Although CZTS-based solar cells have been known to boast superior conversion efficiency in outdoor settings with abundant sunlight, little research has been done on how effective they are in low-light settings, such as overcast weather and indoor environments.The researchers thus set out to develop a CZTSSe film that could be used in a variety of low-light environments, and proved that such film could produce enough electricity to run Internet-of-things (IoT) sensors even in low-light settings. In other words, their CZTSSe thin-film solar cell demonstrated the capability for application to self-powered IoT sensors of various types used in either indoor or outdoor settings.Timely and accurate diagnosis and projection of livestock diseases, including swine fever and foot-and-mouth disease (FMD), based on efficient monitoring is crucial to the containment of contagious animal diseases as well as the welfare of animals. Members of Professor Kim’s team have been working together on multiple projects over the years to develop effective livestock health monitoring systems through collaboration with industries and academic institutions worldwide. The team has included members from 鶹Ӱ (Professor Kim), Chonnam National University (Professor Kim Jin-hyeok), Korea Electronics Technology Institute (Dr. Kim Jin-cheol and Dr. Park No-chang), Green Energy Institute (Dr. Park Jong-seong[KHTC1]), Daeyeon C&I Inc., and University of New South Wales and University of Queensland, both in Australia.This global team has been searching for ways to create a wireless, standalone power system that can reliably supply electricity irrespective of the differences in livestock farming environments. Since developing a self-powered wearable module sensor for livestock health assessment, the researchers have been testing it in Australia.The key to making a device like this possible lies in a solar cell that can be used in both outdoor and indoor environments. To this end, the team first developed a perovskite solar cell with superior output, and published their study in Nano Energy, a widely cited academic journal, in February 2020. The team had also been researching encapsulation technology to ensure the actual applicability of the solar cell they developed, and had their findings published in Solar Energy Materials & Solar Cells in December 2018.Professor Kim explained, “We have developed a wireless, self-powered, wearable sensor module based on our earlier studies, and are now testing it on cattle on a farm in Brisbane. We plan to expand our trial to include large-scale farms in other regions of Australia.”The team regularly organizes their own meetings and exchanges to facilitate better understanding of the technological demands of large livestock farms in Australia and develop solutions accordingly. A leader in advanced livestock and agricultural technologies, Australia has a significant stake in developing reliable solutions for diagnosing livestock health so as to help farmers protect and increase their income. The researchers are now planning to expand the scale of their experiment in Australia with additional support promised by the city of Narromine and its mayor, Craig Davies, in New South Wales.Professor Kim remarked, “When we succeed in developing the final product based on our wearable livestock health diagnosis module, it will very likely find a welcoming market in the Australian livestock industry. We intend to add the big data from our continuing trials and the AI-based model of analysis we are developing to our study and build diagnostic and monitoring platforms by country and livestock species.”The team’s research has been aided by the International R&D Collaboration Program (P0006857) of the Ministry of Trade, Industry and Energy and the Korea Institute for Advancement of Technology, as well as the Korea-Oceania Collaboration Infrastructure Development Program (NRF-2018K1A3A1A17081404) of the Ministry of Science and ICT and the National Research Foundation of Korea.
