- Development of flap array-based triboelectric nanogenerator for omni-directional wind monitoring (2022.11.01)
- Development of flap array-based triboelectric nanogenerator for omni-directional wind monitoring Professor Jongbaeg Kim's research team in the School of Mechanical Engineering developed a wind-driven triboelectric nanogenerator, and the results of this research were published in the journal 'Nano Energy' in November 2022. In this study, a flap array-based nanogenerator capable of generating vortices as a bluff body and simultaneously performing energy conversion was proposed. In addition, the device could be used as an energy source for a wireless environmental sensor and as a self-powered wind vector monitoring sensor.

- A review of solid oxide steam-electrolysis cell systems for green hydrogen production: Thermodynamics and thermal integr
- A review of solid oxide steam-electrolysis cell systems for green hydrogen production: Thermodynamics and thermal integration Professor Jongsup Hong's research group (co-first authors: Gyubin Min and Saeyoung Choi) published a review article on thermodynamic mechanisms and thermal integration of solid oxide steam-electrolysis cell (SOEC) systems with system verification status. Although SOEC systems can produce green hydrogen, one of the most important energy carriers for achieving decarbonization, there has been one critical issue in that the system requires a high-temperature heat source depending on the operating conditions. However, the SOEC system research community has only been focused on electrical characteristics: integration with renewable electricity sources. Therefore, Professor Hong's group analyzed the thermodynamic mechanisms of SOEC systems and suggested potential high-temperature heat sources that can be integrated. Furthermore, Professor Hong's group suggested key operating parameters and performance indices in a standardized manner, on which commercialized SOEC systems were analyzed. This review highlights that the thermal aspect of the SOEC system is as much important as the electrical characteristics. Professor Hong's group is continuing research on the thermal integration of SOEC systems. This review paper has been published in Applied Energy (IF: 11.446, JCR upper 6.3%).

- Endowment agreement ceremony between Multi-scale Fluid Dynamics Lab(MFDL) and Seoul SNU Urology Clinic (2022.09.29)
- Endowment agreement ceremony between Multi-scale Fluid Dynamics Lab(MFDL) and Seoul SNU Urology Clinic Professor Joon Sang Lee's research team at Yonsei University hosted a donation agreement ceremony with Seoul SNU Urology Clinic on September 29 (Thursday) at Yonsei University College of Engineering. The donation will be used for "N-UDS, a non-invasive urodynamic test based on machine learning," developed by The M.E.N.D BioSimulator, the research team's startup company. This technology is a automated platform for bladder and urethral function diagnosis through artificial intelligence. It is expected to be able to broaden the scope of its application to primary medical institutions. Min Young Yoon, director of Seoul SNU Urology Clinic, a hospital dedicated to urology and pain treatment, said, “I moved from the Seoul National University Hospital, a tertiary medical institution, to a primary medical institution, and while diagnosing/treating patients, I felt the importance of cutting-edge diagnostic equipment, so I have collaborated with Professor Lee’s research team. And I decided to donate because I thought that the development of medical diagnostic equipment could be expected by creating a better R&D environment.” The donation will be used to develop diagnostic equipment at the donor's will, and Professor Lee said, "I will use the donated fund to develop equipment so that even primary medical institutions like the SNU urology clinic can utilize the high-quality diagnostic devices."

- 3D engineered tissue models for studying human-specific infectious viral diseases (2022.09.22)
- 3D engineered tissue models for studying human-specific infectious viral diseases Professor Jongbaeg Kim's research team in the Department of Mechanical Engineering and a research team at the Korea Institute of Science and Technology published a review paper on "Three-dimensional engineered tissue model for the study of human-specific infectious virus disease". This paper was published in the journal of 'Bioactive materials' (Impact Factor: 12.874, top 2%) in September 22th, 2022. In addition to coronavirus, which has recently become a social issue, infectious viruses that can cause diseases in various organs of the human body are classified. In addition, a three-dimensional engineered tissue model that can be used for the pathogenesis and treatment of infectious viral diseases similar to in vivo was reviewed.

- Quantitative refractive index tomography of millimeter-scale objects using single-pixel wavefront sampling (2022.09.19)
- Quantitative refractive index tomography of millimeter-scale objects using single-pixel wavefront sampling Professor Chulmin Joo's research team at the Department of Mechanical Engineering introduced an optical diffraction tomography (ODT) method capable of producing 3D refractive index (RI) distribution of transparent samples via a single-pixel detector. Conventional ODT based on optical interferometry can produce high-resolution 3D RI maps, but the interferometry-based ODT is unsuitable for imaging large samples exceeding several tens of micrometers and is greatly influenced by speckle noise. This study presents a noise-robust 3D phase tomography technique suitable for imaging millimeter-scale objects. This research was published in the journal 'Optica' (top 6.93% in Optics, Impact Factor: 10.644) on September 19, 2022. The link: opg.optica.org/optica/fulltext.cfm?uri=optica-9-9-1073&id=503284
