Recent Studies on Bimetallic PtM Catalyst for the Oxygen Reduction Reaction in Polymer Electrolyte Membrane Fuel Cells
고분자 전해질 연료전지의 산소환원반응에 대한 Pt-M 합금 촉매의 최근 연구 동향
Yu-Jin Shim, Won Suk Jung
심유진, 정원석
Korean J. Met. Mater. 2021;59(10):741-752.   Published online 2021 Sep 6
DOI: https://doi.org/10.3365/KJMM.2021.59.10.741

Abstract
Due to environmental pollution and global warming, research on new energy sources that can replace fossil fuels is important. A fuel cell is an eco-friendly energy conversion system that discharges water, and uses hydrogen as fuel. Although platinum is a widely used catalyst in PEMFCs, it has commercial limitations because..... More

                        
Graphene Oxide Coated Silver Nanofiber Transparent Conducting Electrode
전기방사법을 이용한 산화 그래핀-은 나노섬유 투명전극
Jae Young Hyeon, Sung-Hoon Choa, Kyoung Wan Park, Jung Hyun Sok
현재영, 좌성훈, 박경완, 석중현
Korean J. Met. Mater. 2020;58(9):626-632.   Published online 2020 Aug 19
DOI: https://doi.org/10.3365/KJMM.2020.58.9.626

Abstract
We fabricated a transparent conducting electrode composed of graphene oxide (GO) and silver (Ag) nanofibers. The graphene oxide was spray-coated on the Ag nanofiber film, which was fabricated by electrospinning process. Ag/poly(vinyl alcohol) ink was fabricated in a polymer matrix solution using the solgel method. The sprayed film was sintered..... More

Phase-field Modeling of Precipitate Behavior in RPV Steel Using CALPHAD Database
Kunok Chang, Junhyun Kwon, Gyeong-Geun Lee
Korean J. Met. Mater. 2018;56(6):472-478.   Published online 2018 Jun 4
DOI: https://doi.org/10.3365/KJMM.2018.56.6.472

Abstract
We developed a multi-scale modeling framework using the thermodynamic UW1 database of the Fe-Mn-Ni-Si quaternary system. To obtain input data for the phase-field model, such as mobility and interfacial energy data, we used DICTRA software and the TC-PRISMA package with the commercial TCFE8 and MOBFE3 databases. Using the developed framework,..... More
