MgAl2O4 형광체의 광학적 특성에 관한 연구 [PDF]

open access: yes, 2013
학위논문 (박사)-- 서울대학교 대학원 : 재료공학부, 2013. 2. 강신후.MgAl2O4 spinel은 흥미로운 전기적, 기계적, 자성적, 광학적 특성 때문에 여러 분야의 적용을 위해 연구되어 왔다. 더욱이 MgAl2O4 spinel은 광 소자를 위한 모체로도 널리 알려져 있다. 본 연구에서는 티타늄을 MgAl2O4 모체에 도핑하여 단결정 성장으로부터 얻은 청색 발광과는 달리 티타늄 도핑으로부터 백색 발광을 얻었다.

Rational design of Ni‐based catalysts for methane dry reforming: Recent advances and future perspectives

open access: yesFlexMat, Volume 3, Issue 3, Page 428-451, September 2026.
Addressing the challenges inherent in dry reforming of methane (DRM), this paper focuses on the structural design and performance optimization of Ni‐based catalysts. The modulation strategies for DRM are systematically reviewed across four dimensions: the micromorphology of active metals, metal‐support interactions, electronic modifications by ...

The Influencing Factor of MgAl2O4 on Heterogeneous Nucleation and Grain Refinement in Al Alloy Melts

open access: yes, 2020
Grain refinement using oxide additions is commercially feasible and ecofriendly. MgAl2O4 has a lattice structure similar to Al and small lattice misfits with Al, and it can be an effective nucleation core when it meets certain conditions.

High‐Temperature Evolution of a Core–Shell TBC: Linking Microstructure to CMAS, Sintering, and Fracture Resistance

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
This graphical abstract summarizes the key findings on the high‐temperature evolution of a core‐shell thermal barrier coating (TBC). Upon annealing, alumina redistribution remains confined to the shell region. The core‐shell TBC demonstrates superior retention of CMAS resistance, sintering resistance, and fracture toughness compared to the benchmark ...
