Research Team from Department of Physics and Chemical Engineering and Materials Science at Ewha Suggests a Strategy ...

Research Team from Department of Physics and Chemical Engineering and Materials Science at Ewha Suggests a Strategy to Enable Exciton Funneling and Boost Visible Light Emission in 2D Inorganic Semiconductors A joint research team at Ewha reports rapid transfer of photogenerated excitons and enhanced light emission from 2D inorganic semiconductors integrated with blue-fluorescent organic molecules. The results of the study, which highlights a strategy to develop a new type of optoelectronic devices, were published in the online edition of Advanced Science (IF: 16.806), a world-renowned academic journal within the top 4.4% in the field of materials science, on June 16 (Thu.). (from left) Prof. Youngmin You, Prof. Dong-Wook Kim, Dr. Soyeong Kwon The team led by Professors Dong-Wook Kim at the Department of Physics and Youngmin You at the Department of Chemical Engineering and Materials Science confirmed the enhancement of luminescence due to exciton transfers in heterostructure interfaces comprised of two-dimensional semiconductor transition metal dichalcogenides (TMD) and fluorescent organic molecules. Professor Kim fabricated heterostructures by stacking evaporated thin films of DY1 fluorescent molecules on TMD MoS2 monolayers. The DY1 fluorescent molecules used in the process were obtained by the team led by Prof. You during the team’s OLED development researches. Optical characterizations and probe-based surface charge distribution measurements revealed exciton transfer from DY1 molecules to the MoS2 monolayers, which led to 1.7-fold enhanced light emission from MoS2. It has been reported that charge transfer rather than exciton transfer is dominant at the interfaces of different TMD materials. This work successfully demonstrated exciton transfers in the hybrid heterostructures by stacking fluorescent organic molecules on TMDs. The team could also propose a way to identify the transfer process of charges and excitons, based on the complementary use of measuring optical properties and analyzing scanning probe microscopes.

(Right) Enhanced light emission characteristics and extension of exciton lifetime of the DY1/MoS2 hybrid heterostructure (small figure). Dr. Soyeong Kwon at the Department of Physics remarked as the first author of the paper, “Given the various trials and errors as well as numerous difficulties that I went through while studying the novel research subject of organic and inorganic heterostructures over the last two years of my Ph.D. course, I feel an even deeper sense of satisfaction and fulfillment. I also hope that our findings will be followed by many follow-up studies.” The paper, titled “Exciton Transfer at Heterointerfaces of MoS2 Monolayers and Fluorescent Molecular Aggregates,” was conducted through collaborative research by the Department of Physics at Ewha (Professor Seokhyun Yoon and Taeyoung Choi), the Institute of Basic Science at Sungkyunkwan University (Professor Ji-Hee Kim and Ki Kang Kim), and the Department of Physics at Chungnam National University (Professor Ki-ju Yee), with support from the National Research Foundation of Korea and the Institute for Basic Science. Professors Dong-Wook Kim and Youngmin You, the corresponding authors of this paper, are supported by the Basic Research Laboratory grant.

Research Outcome Produced by a Team Comprised of an Undergraduate Student from the Chemical Engineering and Materials Science Major and Graduate Students Published in an SCI-grade Journal A phase transition in two-dimensional (2D) materials first identified using nano-radiation beams Excellent results of joint research alongside graduate student mentors produced through a practical class for undergraduate students (from left) Lee Ha Heun, Yim Eunji, Kang Seohui Senior student Yim Eunji from the Chemical Engineering and Materials Science major of the ELTEC College of Engineering and graduate students Lee Ha Heun and Kang Seohui (advisor: Prof. Suyeon Cho) from the System Health Convergence major, who were chosen for the fourth phase of the Brain Korea 21 (BK21) Project (Director: Prof. Oran Kwon), published the results of joint research on a phase transition in 2D materials using nano-radiation beams that was conducted with a team led by Dr. Chiang from the National Synchrotron Radiation Research Center (NSRRC) based in Taiwan. The outcome of this research, supported by the Overseas Large-scale Research Facility Utilization Support Project of the National Research Foundation, was published under the title of “Local phase transition at crack edges of Mo1-xWxTe2 polymorphs” in the online edition of Applied Surface Science (IF: 6.707, top 4.76 percent of JCR), an SCI-grade journal. A structural phase transition in 2D materials has attracted considerable attention in academia as it enables reversible conversion between semiconductors and conductors caused by the external environment. The research team from the Chemical Engineering and Materials Science major analyzed the nanoscale physical properties of a structural semiconductor-to-metal phase transition in a thin Mo1−xWxTe2 alloy sample with a thickness of several nanometers using nano X-ray diffraction and nano X-ray fluorescence with nano-radiation beams. As a result, the research team confirmed that, when a sample is synthesized in an alloyed form, the distribution of tungsten (W) becomes uneven at the critical point of a phase transition, and that the higher the tungsten content, the lower the amount of energy required for a phase transition. The research team identified the effects of substitutional elements in 2D materials on a structural phase transition therein. This is expected to further expand the applications of 2D materials used in a wide range of areas including energy conversion and optoelectronic devices. In particular, this research was developed into a thesis led by Lim Eunji alongside graduate student mentors Lee Ha Heun and Kang Seohui in a seasonal class named “Advanced Chemical Engineering and Materials Science Lab” conducted by the Chemical Engineering and Materials Science major. The class is a practical course in which students conduct self-directed research under the guidance of a professor in the laboratory of the full-time faculty member during a school vacation, and is continuously resulting in outstanding achievements such as allowing students to carry out self-directed research, give a presentation at an international conference and present a senior thesis.

Professor Sang Won Kang Attracts an Investment of KRW 18 Billion Following the Development of a New Drug...

Professor Sang Won Kang Attracts an Investment of KRW 18 Billion Following the Development of a New Drug to Treat Vascular Diseases Faculty start-up company “Vasthera” attracted an additional investment of KRW 18 billion, two years after receiving KRW 5.5 billion in investment following the development of a new drug to treat vascular diseases. “Vasthera” is a biotechnology company that aims to develop first-in-class new drugs for cardiovascular diseases and cancers. It was established in February 2018 as an Ewha faculty start-up company, as Professor Sang Won Kang of the Department of Life Sciences transferred a patent based on the results of research on redox signaling in the field of therapeutics for vascular diseases and cancers. Vasthera attracted an investment worth KRW 18 billion in late February 2021. Existing investors ID Ventures, SJ Investment Partners and Medytox Venture Investment also chose to participate in the follow-up investment, while UTC Investment, Medici Investment, Shinhan Venture Investment, Partners Investment and HG Initiative/Daesung Venture Capital joined the venture as new investors. This marks a significant achievement two years after the attraction of the initial investment worth KRW 5.5 billion, thereby reaching a cumulative investment of KRW 23.2 billion so far. With this new investment, Vasthera has gained a foothold for conducting a clinical trial on new drug candidates for pulmonary artery hypertension (PAH) and a pre-clinical study on triple-negative breast cancer (TNBC). The research team led by Professor Sang Won Kang had previously identified the role of redox signaling in certain diseases and conducted research on the potential of targeted therapeutics. The research team examined peroxiredoxin-2, an essential antioxidant enzyme, as a targeted drug for redox signaling. The team had already published the study outcome that peroxiredoxin-2 regulated platelet-derived growth factor (PDGF) signaling and vascular remodeling in Nature in 2005, and had since published study results that a peroxiredoxin-2 activity mimetic could normalize vascular function in academic journals in 2011 and 2013. Professor Sang Won Kang explained, “Redox signaling is a new mechanism that proves the fact that reactive oxygen species (ROS) are by-products of normal cell activity, which is a relatively less well-understood mechanism that was only discovered around 20 years ago,” and added, “As a leading company in developing new drugs targeting signaling pathways, Vasthera found that the loss of function in enzymes related to redox signaling may cause vascular diseases and cancers, and that the recovery of the lost function can be a treatment option.” The research team discovered a substance that accurately imitates peroxiredoxin-2 activity among natural substances and succeeded in developing a new drug named VTA-04, which newly synthesizes the component responsible for activity. The first target disease to be treated by VTA-04 was determined as PAH, a rare vascular disease, and the targets are expanding to cancers and brain disorders. The therapeutic developed through this study is different from existing therapeutics in that it was developed to target blood vessels from the beginning. The team will complete the development of the dosage form of the new PAH drug VTA-04 for clinical use within the first half of this year, and plans to expand the treatment targets to TNBC among malignant tumors, brain disorders and more in the future.

Undergraduate Students from the Department of Computer Science and Engineering Publish a Research Paper in an SCI...

Undergraduate Students from the Department of Computer Science and Engineering Publish a Research Paper in an SCI-grade Journal Su-ji Yoon and Hee-jin Park Su-ji Yoon and Hee-jin Park, undergraduate students of the ELTEC College of Engineering majoring in Computer Science and Engineering in the incoming class of 2019, conducted research on drastically reducing DRAM memory consumption in IoT (Internet-of-Things) systems, and published the paper as co-first authors in IEEE Access, a major open access journal of the Institute of Electrical and Electronics Engineers (IEEE) Computer Society. As the size of data in IoT environments has rapidly increased in recent years, DRAM usage is also increasing alongside a subsequent leap in battery consumption. Real-time systems such as IoT systems are “mission-critical” systems in which it is essential to complete tasks within a fixed time without fail. Since all tasks in such systems reside on the memory, such systems face the problem of high memory consumption because they are unable to use the swapping method to temporarily retain tasks in storage as with general-purpose computer systems. The undergraduate research team optimized the swap ratio for each task and reduced DRAM usage by 34 percent by employing evolutionary computation, a kind of artificial intelligence (AI) technology. In addition, the team succeeded in saving battery consumption by 31 percent through the combination of memory-swapping technology and CPU voltage scaling technology. While these power-saving technologies generally have the side effect of slowing down task execution, the research team achieved an optimal outcome that met the deadline for all tasks and maximize the power-saving effect through the accurate modeling of the worst-case execution time. The pertinent research paper, titled “Supporting Swap in Real-Time Task Scheduling for Unified Power-Saving in CPU and Memory,” is the outcome of joint research by the two undergraduates with Research Professor Kyungwoon Cho (third author) and Professor Hyokyung Bahn (corresponding author) during their research internship period for undergraduate students at the Embedded Software Research Center, which marks a meaningful demonstration of the outstanding capabilities of Ewha undergraduates in the Computer Science and Engineering major. The Department of Computer Science and Engineering helps undergraduates to foster their research capabilities by participating in wide-ranging academic research activities through a research internship program and achieve academic accomplishments. Su-ji Yoon and Hee-jin Park, the co-first authors, expressed their feelings about participating in the program, commenting, “We believe we were able to produce positive results in a short period of time by building upon open-source code at the research center, rather than writing the source code required for our experiments from scratch.” Professor Hyokyung Bahn, who supervised the research as a corresponding author, remarked, “As recent studies in computer science have been conducted using open-source software, the source code for such studies are being made available to the public, rather than only publishing their outcomes in academic papers. This is increasingly cutting down on the time required for creative undergraduate students to produce new results based on existing studies,” and added, “The research outcome of these students was also published in open source, which I hope will challenge other students to achieve even better research outcomes.”
