• The researchers used a hydrothermal process to grow CuCo2O4 or Co3O4 on a substrate made of the same material as the receiver tubes, a nickel-chromium-tungsten-molybdenum alloy (Haynes 230) with excellent high-temperature strength and oxidation resistance. Zehui Du, group leader at the Temasek Laboratories at Nanyang Technological University of Singapore, who did not participate in the study, further comments that their structures “are very similar to the core–shell ZnO/TiO2 or MnO2/ZnO nanorods that have been developed to enhance energy density or device performance. Applying an oxide ceramic coating onto a metal or another oxide nanostructure can be a facile approach to enhance the thermal stability at elevated temperature and to tailor the optical properties as well as electrical and mechanical.
