Recent Research Trends for Improving the Stability of Organo/Inorgano Halide Perovskites
유무기 하이브리드 할라이드 페로브스카이트의 안정성 향상을 위한 연구 동향 리뷰
Myeong Jin Seol, Jeong Woo Han, Seung Hwan Hwang, Soo Young Kim
설명진, 한정우, 황승환, 김수영
Korean J. Met. Mater. 2022;60(1):1-13.   Published online 2021 Dec 10
DOI: https://doi.org/10.3365/KJMM.2022.60.1.1

Abstract
Because of their superior optical, and electrical properties, lead halide perovskites have emerged as potential materials for light-emitting-diodes. However, some obstacles have yet to be overcome for practical applications including low exciton binding energy, the difficulty of fabricating uniform perovskite films,, and their instability to heat, light, and moisture. In..... More

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
