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...

source:ACS PubicationsRare-earth adatoms on surfaces have been studied for potential atomic-scale magnetic storage, quantum sensing, and quantum computing applications. Despite accumulating experimental efforts, a comprehensive description of the electronic configurations of the adatoms remains elusive. Here, we investigate two charge states and several electronic configurations, including 5d and 6s valence shells, for a Sm adatom on a MgO substrate using multiconfigurational ab initio methods, for the possibility of using the Sm nuclear spin levels as qubits. For the configurations in a neutr...
