In-situ analysis of the Al-Fe-Mn-Cu oxide oxygen carrier for chemical looping applications
Chemical Engineering Journal Advances, 2022 A novel Al-Fe-Mn-Cu oxide oxygen carrier, termed Gen3, was developed by NETL and prepared using natural ore and pigment grade materials. Gen3 was subjected to 10 cycles of reduction-oxidation (redox) through confocal laser scanning microscopy (CLSM) and ...

Synthesis, densification, and cation inversion in high entropy (Co,Cu,Mg,Ni,Zn)Al2O4 spinel
Journal of Asian Ceramic Societies, 2023 The synthesis, densification behavior, and crystallographic site occupancy were investigated for four different spinel-based ceramics, including a high-entropy spinel (Co0.2Cu0.2Mg0.2Ni0.2 Zn0.2)Al2O4. Each composition was reacted to form a single phase,
