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...

source:Tohoku UniversityA new catalyst structure offers a potential pathway toward more cost-effective hydrogen production via water electrolysis. The material centers on mesoporous single-crystalline Co3O4 doped with atomically dispersed iridium (Ir), designed for the acidic oxygen evolution reaction (OER).Iridium is known for its OER performance but is both scarce and expensive. Efficient use of Ir while maintaining stability is a major challenge for scaling up electrolyzer technologies. A new study published in the Journal of the American Chemical Society proposes a solution using a materia...

source:Phys.orgThe willingness of the 4f orbitals of lanthanide metals to participate in chemical reactions is as rare as their presence in Earth's crust. A recent study, however, witnessed the 4f orbital in a cerium-based compound actively participate in bond formation, triggering a unique chemical reaction.The researchers observed that a cerium-containing cyclic complex formed a 4f-covalent interaction, leading to a ring-opening isomerization from cyclopropene to allene. The findings are published in Nature Chemistry.Lanthanides are heavy, rare-earth metallic elements, occupying position...
