Advanced Energy Materials, EarlyView.We report a Pt‐decorated Co‐doped BiFeO3 (Pt/BCFO) piezocatalyst achieving an H2 evolution rate of 1896.4 µmol g−1 h−1. Co‐doping induces lattice distortion, enhancing piezoelectric polarization, while Pt sites promote water dissociation. Embedded in a poly(vinylidene fluoride) matrix, Pt/BCFO enables efficient mechanical energy harvesting and catalyst

k‐Selective Electrical‐to‐Magnon Transduction with Finite‐Element‐Resolved Sub‐Micron Nanoantennas
Advanced Physics Research, EarlyView.We introduce a coupled finite‐element‐finite‐difference framework that links impedance‐matched nanoantenna geometries to propagating spin‐wave dynamics, capturing skin effects, proximity effects, and taper leakage beyond uniform‐current models. Applied to coplanar‐waveguide and stripline nanoantennas on yttrium‐iron‐garnet, the simulations achieve ...

Adsorption isotherm on ferrites
Communications, Faculty Of Science, University of Ankara Series B Chemistry and Chemical Engineering, 1994 Tlıe corrosion behaviour of the prepared Materials was studied by mcans of weight-loss techniquc in stagnant solution of (0.01 M) sulphuric acid in presence of thiourea as an inhibitor. Higher concentration of thiourea reduces the corrosion rate of thc samples and proteetion effi- cicncy of thiourea was found to be 80 % for ferrites Proteetion is ...
