- Oxide–Carbon Nanofibrous Composite Support for a Polymer Electrolyte Membrane Fuel-Cell Catalyst (Ph.D. Yukwon Jeon)
- <abstract> Well-designed electronic configurations and structural properties of electrocatalyst alter the activity, stability, and mass transport for enhanced catalytic reactions. We introduce a nanofibrous oxide–carbon composite by an in situ method of carbon nanofiber (CNF) growth by highly dispersed Ni nanoparticles that are exsoluted from a NiTiO3 surface. The nanofibrous feature has a 3D web structure with improved mass-transfer properties at the electrode. In addition, the design of the CNF/TiO2 support allows for complex properties for excellent stability and activity from the TiO2 oxide support and high electric conductivity through the connected CNF, respectively. Developed CNF/TiO2–Pt nanofibrous catalyst displays exemplary oxygen-reduction reaction (ORR) activity with significant improvement of the electrochemical surface area. Moreover, exceptional resistance to carbon corrosion and Pt dissolution is proven by durability-test protocols based on the Department of Energy. These results are well-reflected to the single-cell tests with even-better performance at the kinetic zone compared to the commercial Pt/C under different operation conditions. CNF/TiO2–Pt displays an enhanced active state due to the strong synergetic interactions, which decrease the Pt d-band vacancy by electron transfer from the oxide–carbon support. A distinct reaction mechanism is also proposed and eventually demonstrates a promising example of an ORR electrocatalyst design. https://pubs.acs.org/doi/10.1021/acsnano.8b02040

- Detection of Highly Pathogenic Influenza Virus via a Viral Fusion and Cell Entry Mechanism Prof. Seungjoo Haam
- 'Highly and lowly pathogenic' AI can be discriminated in 30 minutes. Yonsei University and Korea University team developed the technology together..."Application of Host Cell Mimic Polymersomes" Since the highly pathogenic avian influenza virus (HPAIV) has crossed the species barrier to humans, early and accurate diagnosis between the highly pathogenic and the lowly pathogenic form of the virus is considered the key issue. FluSome, reported by Daesub Song, Seungjoo Haam, and their co‐workers in article 1800960, is a novel highly specific surveillance tool for carrying out early preventative procedures for controlling the HPAIV outbreaks.

- Graduate students in prof. Jong Hyeok Park's research team developed high efficiency photocatalysis
- Cho Yoon-joon (integrated 3 semesters) and Kim Sung-soon (three semesters of master's degree) in professor Jong Hyeok Park's research team, developed new photocatalysis which can produce hydrogen energy efficiently that is regarded as a next-generation energy source through water decomposition. Titanium dioxide(TiO2) nanoparticles, the existing representative photocatalysis material is composed of single phase or dual phases. However, this study first reported that a multiple heterojunction system consisting of three different phases within single titanium dioxide nanoparticles is possible. The multi-phase junction system has a special charge distribution inside, so that electrons and holes are efficiently separated and showed high photocatalytic water decomposition performance. This study is especially meaningful in that the two graduate students have been jointly conducted since the days of undergraduate researchers and have recently completed it. The result of this study were published in the journal 'Nano Letters'(IF : 12.080), an authoritative journal in the field of nanoscience in the world.

- [ETNEWS] HANS Lab, Development of Catalysts using Machine Learning and Research on Radiation Chemistry
- [ETNEWS] issue date : 2018.03.21 <Yonsei University HANS Lab Team> Recently, a computer simulation method built on a supercomputer has opened a way for experiments to study dangerous materials (radioactive materials). In particular, quantum physics 'first principle' computerized material technology is creating a new research paradigm such as the construction of big data to be implemented by the fourth industrial revolution and the innovative reduction of the cost of commercialization of new materials. The High-throughput Ab-initio Nanomaterials Simulations laboratory (professor Han Byungchan) of Yonsei University, which is studying the first principle of computerized materials science, has recently achieved some results. First, they developed a catalyst that enables efficient electrical energy production through a hydrogen fuel cell system, a clean gas, and secondly, a disaster prevention agent to cope with accidents involving toxic chemicals. Third, we have published research results that understand the chemical behavior of high-level highly toxic substances and treat them safely with computerized radiochemistry. This is a study that suggests the possibility of separating and acquiring materials such as rare earths as well as reducing the volume of high-level radioactive waste. The laboratory also succeeded in clarifying the fundamental principles of physical properties by computer simulation. This methodology is being developed as a systematic computerized platform linked with quantum mechanics and machine learning. <Han Byungchan, Director of HANS Lab Team> “Interpreting the key materials of the renewable energy system quickly and finding the key factors for determining the physical properties will be a precedent for promoting the fourth industrial revolution in the true sense,” said Han Byungchan, a professor in charge of the research. 전자신문인터넷 윤나영 기자 (firstname.lastname@example.org ) SOURCE : www.etnews.com/20180321000361
