Research Paper by Professor Chang-Hyeon Ji Published in World-Renowned Academic Journal Additive Manufacturing

Expectations for the application of 3D printing technology in fabricating microactuators and commercial application of LiDAR system as an essential technology for fully autonomous driving and smart factories A research team led by Professor Chang-Hyeon Ji at the Dept. of Electronic and Electrical Engineering developed an electromagnetically-actuated scanning micromirror device for LiDAR systems using three-dimensional (3D) printing and published the results in Additive Manufacturing (IF: 11.632), a prestigious top 1% journal in engineering and manufacturing. A LiDAR (Light Detection and Ranging) system refers to a remote sensor that measures the distance to a target by shining a light onto the target’s surface using near-infrared light and then detecting the reflective light emitted from the surface with an optical sensor. This allows the system to accurately detect not only the distance to a target but also location and morphology of the target, attracting attention as an essential technology to achieve a fully autonomous vehicle. The research team of Professor Chang-Hyeon Ji devised a LiDAR scanning micromirror device capable of 360-degree scanning and fabricated the device by multi-jet fusion(MJF) 3D printing, a powder bed fusion process. The device developed by the Ewha research team was fabricated through the 3D printing process while a conventional scanning micromirror was made of silicon wafers using the microelectromechanical systems (MEMS) technology. This is a pioneering outcome in fabricating microactuators using 3D printing technology, which is conventionally used for the construction of macro-scale structures. In addition, compared with motor-based scanners applied to mechanical LiDAR systems or scanning micromirrors fabricated using the MEMS technology, it has the capacity to achieve high performance with short production time and low production cost, leading to expectations of the commercial application of LiDAR systems. The team led by Professor Chang-Hyeon Ji at the Dept. of Electronic and Electrical Engineering drew attention by publishing the research paper, titled “Electromagnetic Omnidirectional Scanning Micromirror with Multi Jet Fusion Printed Structures for Smart Factory Applications,” marking the outcome of the project conducted with support from the Phase 4 Brain Korea 21 (BK21) project, in a renowned journal in the relevant field. In October last year, Ewha was selected for the smart factory sub-field under the “new industry” category of the innovative talent training program in the BK21 project hosted by the Ministry of Education (MOE). The ‘‘Education and Research Group for training intelligent IIoT (Industrial Internet of Things) convergent talents for human-centric smart factories” (led by Professor Jeong Tae Kim) is composed of ten professors from the Dept. of Electronic and Electrical Engineering and three professors from the Division of Mechanical and Biomedical Engineering at ELTEC College of Engineering, and is carrying out several studies focused on the five core areas of smart factories: smart network, AI & big data, smart sensors, human-centric systems, and cyber physical systems.

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. (Left) A schematic diagram to illustrate the transfer of excitons generated from DY1, a self-developed fluorescent organic molecule, to an adjacent two-dimensional semiconductor MoS2 monolayer. (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.

ELTEC College of Engineering Selected as Nation’s First Specialized Graduate School for Convergence Analysis of Meteorological and Climate Data The ELTEC College of Engineering was selected as the nation’s first specialized graduate school for the convergence analysis of meteorological and climate data. The program for the specialized graduate school for the convergence analysis of meteorological and climate data was newly introduced this year by the Korea Meteorological Administration (KMA) and the Korea Meteorological Institute (KMI) to foster talented youths with the capacity to lead emerging future industries based on meteorological big data analysis. With the gradual increase in damages from weather-related disasters caused by climate change, meteorological big data analysis and utilization skills and climate change response capabilities have become more important than ever as they can directly affect a country’s future competitiveness. In relation to this program, Ewha Womans University and the KMI have agreed to begin cooperating in fostering specialists in the field of meteorology and held an “MOU Signing Ceremony for the Specialized Graduate School Program for the Convergence Analysis of Meteorological and Climate Data” at the ECC on June 10 (Fri.). Following this selection, Ewha is expected to receive government grants and climate change response funds amounting to KRW 2.268 billion to operate the program over the next four years and seven months. Ewha will select scholarship recipients this fall semester among graduate students who are enrolled in courses related to convergence, analysis, and utilization of meteorological and climate data and participating in a university-industry cooperation program. Ewha is planning to recruit at least 15 students each year to join the master’s and doctoral program of the specialized graduate school for the convergence analysis of meteorological and climate data in addition to the track course program, and open the graduate school this September to train master’s and doctoral students to become experts in the convergence, analysis, and utilization of meteorological and climate data. Ewha will also offer various courses, such as weather forecasting using artificial intelligence, climate modeling, and data analysis for sustainable energy (e.g., CCUS, renewable energy, and hydrogen energy), and develop business internship programs at the school that will lead to full-time job opportunities. Furthermore, each year, Ewha will produce specialists who can consistently introduce innovations and advancements in meteorology as well as various fields of convergence studies and publish papers in international journals. Graduates of the specialized graduate school will gain in-depth knowledge that will allow them to immediately enter into various industries, including fields that require the convergence, analysis, and utilization of meteorological and climate data. The Department of Climate and Energy Systems Engineering has been rapidly growing while conducting a variety of studies and projects since its establishment in 2016, and has since become one of the most popular majors in Korea because of its future-oriented convergence education and research that contribute to solving complex issues, such as climate change response, energy, and environmental, social, and governance (ESG) management.

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.
