Electrochemical Activation Applied to Perovskite Titanate Fibers to Yield Supported Alloy Nanoparticles for Electrocatalytic Application

open access: yesSmall, Volume 19, Issue 1, January 4, 2023., 2023
In situ exsolution on 200 nm diameter perovskite fibers was performed to give with NiCo or Ni3Fe bi‐metallic nanoparticles with average diameter about 29 and 35 nm, respectively. The perovskite fibers were utilized as cathode materials in pure CO2 electrolysis cells due to their redox stability in the CO/CO2 atmosphere.

Electronic properties and Fermi surfaces MgCNi$_{3}$ and related intermetallics [PDF]

open access: yesarXiv, 2001
The band structure of the new perovskite-like superconductor MgCNi$_{3}$ was studied by the self-consistent FP-LMTO method. The superconducting properties of MgCNi$_{3}$ are associated with an intensive peak in the density of Ni3d states near the Fermi level. The absence of superconductivity for nonstoichiometric compositions MgC$_{1-x}$Ni$_{3}$ is due
