Indium-doped manganese oxide materials have been hydrothermally synthesized. Doped indium was found to be in framework sites in synthetic cryptomelane. Cyclic voltammetry (CV) results show that manganese oxide doped with indium generates electrocatalytic activity for the O2 reduction reaction.

This study theoretically and experimentally investigates the transmission properties of a metamaterial slab comprised of two layers of metallic fish-scale structure arrays and a sandwiched dielectric layer. Calculations show that the asymmetric transmission can be tuned by varying the slab thickness, due to near-field interlayer coupling. The spatial evolution of the electric field indicates that the twist structure functions as a perfect polarization transformer at certain frequencies. Measured transmission spectra are in good agreement with calculated results when material dissipation is considered.
