来源：ACS PublicationsThe growth of high-entropy alloy (HEA) thin films using the molecular beam epitaxy (MBE) technique widens our horizons in materials design. This technique offers precise control of key parameters (deposition rate, substrate orientation, interfacial, or lattice strain), and it becomes possible to study the interplay existing between the elemental choice, their respective stoichiometry, and the associated physical and chemical properties. Such fine-tuning of HEA with an immense compositional space will bring additional advanced materials with exotic properties. Here, we report...

From Oxidized PrNi0.9Al0.1O3 to Reduced PrNi0.9Al0.1O2+δ Perovskite Nickelates: Stabilization of Infinite-Layer Specimens with Monovalent Ni in the Bulk Polycrystalline Form 来源：ACS PublicationsRecently, a new class of high-temperature superconductors, RNiO2 (where R represents rare-earth elements) with infinite-layer (IL) structure, has been identified. They possess the same structural framework as the renowned high-Tc cuprates but with nickel replacing copper as the central element. In this study, we successfully synthesized infinite-layer samples of PrNi0.9Al0.1O2+δ in the bulk polycrys...

Rational Synthesis of Rare-Earth-Doped Co3O4 Nanostructures: Insights into Eu3+-Induced Oxygen Vacancies for Enhanced Battery-Type Hybrid Supercapacitor Performance 来源：ACS PublicationsCobalt oxide (Co3O4) has emerged as a promising electrode material for energy storage due to its high theoretical capacity. However, its practical application is limited by poor electrical conductivity, sluggish charge transfer kinetics, and restricted electrochemical activity. To overcome these limitations, rare-earth (RE) doping has been explored as a strategy to tailor the physicochemical properties...
