来源：TALANTA OPEN Volume11 DOI10.1016/j.talo.2025.100411Zinc oxide (ZnO) serves as a highly adaptable semiconductor with a crucial role in various applications because of its crystal structure compatibility and significant band gap. Fabricating ZnO nanomaterials with tailored characteristics has become a prevalent and current focus. Within this framework, the integration of rare earth metals sparks interest due to their distinctive 4f electronic configuration, providing an exceptional opportunity to manipulate ZnO's optical, luminescent, and surface properties. This article examines the impa...

Melting temperature, emissivity, and thermal conductivity of rare-earth silicates for thermal and environmental barrier coatings source:SCRIPTA MATERIALIAIn recent years, rare-earth silicates have become the industry standard for coating state-of-the-art SiC ceramic matrix composite (CMC) gas turbine engine components, due to their low volatility, high melting point, and thermal shock resistance. Current research is focused on designing rare-earth silicate based thermal- environmental barrier coatings (T/EBCs) with improved resistance to CMAS (CaO-MgO-Al2O3-SiO2), steam, and crack formati...

source:Phys.orgQuantum technologies, which leverage quantum mechanical effects to process information, could outperform their classical counterparts in some complex and advanced tasks. The development and real-world deployment of these technologies partly relies on the ability to transfer information between different types of quantum systems effectively.A long-standing challenge in the field of quantum technology is converting quantum signals carried by microwave photons (i.e., particles of electromagnetic radiation in the microwave frequency range) into optical photons (i.e., visible or near...

source:presstvThe pilot plant at the Abbas Abad Industrial Town has been indigenously designed and built by young Iranian experts, he said, hailing it a “great achievement” which will enable the country's access to high-tech industries to continue at a faster pace.Iranian companies were able to design, manufacture, install, and commission 100% of the equipment, some of which was manufactured and operated for the first time in the country.Before manufacturers can use the rare earth material extracted from the ground, it must go through a complex and expensive process.The first step is to mi...
