Electromagnetic wave-absorbing behavior of soft-magnetic medium entropy alloys with BCC/L21 coherent microstructure

Materials & Design, 2022
Magnetic alloy powders show a great superiority in the balance of permittivity and permeability for electromagnetic (EM) wave-absorption. However, it is necessary to enhance their effective absorption bandwidth (Δf) and impedance matching due to their ...

Surface Nanostructuring of Copper Using Fluoride and Chloride

ChemElectroChem
Copper is an active electrocatalyst for various energy conversion reactions, but its performance depends on the structure of the active surface sites. In this work, we propose a simple strategy to tailor both the roughness and the active site's geometry ...
