- Development of a flexible tactile display based on liquid-to-gas phase change microactuator array (2023.01.19)
- Development of a flexible tactile display based on liquid-to-gas phase change microactuator array Professor Jongbaeg Kim’s research group in the Department of Mechanical Engineering developed a flexible tactile display that can be attached to the skin to transmit sophisticated tactile information. For sophisticated tactile transmission, this research team used a phase change actuator that can produce large output during liquid to gas phase change, and developed a device with higher spatial resolution than previous studies to enable more realistic tactile transmission to users. The study was presented at the 2023 36th IEEE MEMS Conference, the most prestigious academic conference in the MEMS field. On a basis of the excellence of the research, the presentation was selected as the Outstanding Student Poster Presentation Award Finalist, which is awarded only to 10 poster presenters among a total of 635 papers.

- 3D Printing of Thylakoid-PEDOT:PSS Composite Electrode for Bio-Photoelectrochemical Cells (2023.01.05)
- 3D Printing of Thylakoid-PEDOT:PSS Composite Electrode for Bio-Photoelectrochemical Cells Professor Ryu Won-hyung's research team (co-author Dr. Kim Yong-jae, Kim Sun-il, integrated course student) developed a new eco-friendly energy technology that can convert sunlight into electrical energy by mixing a tilakoid membrane extracted from spinach and a conductive polymer (PEDOT:PSS). (Y. J. Kim, S. I. Kim et al, ACS Applied Energy Materials, (2023)) The study presented the potential for 3D printing of tilakoid and suggested that higher-efficiency electrodes could be produced by increasing the surface area of the structure according to various designs.

- Aero-manufacture of nanobulges for an in-place anticoronaviral on air filters (2023.03.05)
- Aero-manufacture of nanobulges for an in-place anticoronaviral on air filters A team of researchers lead by Professor Jungho Hwang developed an electrically operable dispenser for decorating continuous ultrafine Fe–Zn, Fe–Ag, or Fe–Cu particles (<5 nm) onto SiO2 nanobeads to form nanobulges with antiviral characteristics. The finding of this research was published the Journal of Hazardous Materials (I.F. 12.50).The resulting nanobulges were exposed to human coronaviruses (HCoV) to assess antiviral function. The nanobulges exhibited comparable antiviral activity to Zn, Ag, and Cu particles while retaining biosafety in both in vitro and in vivo models because of the significantly smaller metallic fractions. The interest in removing contagious viruses from indoor air using ventilation and filtration systems is increasing rapidly because people spend most of the day indoors. The development of an effective platform to regenerate the antiviral function of air filters during use and safe abrogation of used filters containing infectious viruses is a very challenging since an on-demand safe-by-design manufacture system is essential for in-place antiviral coatings. *This study was supported by the Technology Innovation Program (20007027, Mutually beneficial cooperative air purifying automobiles against atmospheric fine particles) funded By the Ministry of Trade, Industry & Energy (MOTIE, Korea).

- MEMS Shock Absorbers Integrated with Al2O3-Reinforced, Mechanically Resilient Nanotube Arrays (2023.1.15)
- MEMS Shock Absorbers Integrated with Al2O3-Reinforced, Mechanically Resilient Nanotube Arrays Dr. Eunhwan Jo and Professor Jongbaeg Kim's research team developed ceramic-reinforced carbon nanotube-based shock absorbers. The vertically aligned nanotube bundles, introduced in this study, can be selectively integrated into micro-electro-mechanical systems (MEMS), which effectively protects micro mechanical structures that may be vulnerable to mechanical collisions. This research was presented as an oral presentation at 2023 36th IEEE MEMS Conference, the most prestigious academic conference in the field of MEMS. Also, on a basis of the excellence of the research, the presentation was selected as the Outstanding Student Oral Presentation Award Finalist, which is awarded only to 20 oral presenters among a total of 635 papers. The research was conducted in collaboration with Harvard Medical School and is expected to be used in various MEMS devices such as accelerometers, gyroscopes, and micro mirrors, which are attracting attention as core parts of the Internet of Things, mobile devices, and future automobiles, to dramatically improve the impact stability of the devices. *This work was supported by the National Research Foundation of Korea(NRF) grant funded by the Korea government(MSIT).

- Development of high-activity water electrolysis catalyst for high-efficiency alkaline fuel cell (2022.12.15)
- Development of high-activity water electrolysis catalyst for high-efficiency alkaline fuel cell Professor Seong Chan Jun's research team in the department of mechanical engineering has developed a robust catalyst with high activity and high efficiency for efficient water electrolysis. A very active electrocatalyst similar to Pt/RuO2 is required for application to commercial high-efficiency alkaline fuel cells, but there is still a limitation in that it is difficult to synthesize. This research team overcame this limitation by using N-doped noble metal iridium diphosphide (N-IrP2 @CC) to achieve higher water decomposition current density than conventional catalysts. The results of this study were confirmed for publication this December in 'Applied Catalysis B: Environmental' (Impact Factor: 24.319, within the top 2%, Volume 319), an international excellent journal.
