Design of Heterostructured Mo:BiVO4/Tio2 and Mo:BiVO4/Co‐Pi Photoanodes for Efficiency and Durability Comparison In Solar‐Driven Water Oxidation Under Acidic Conditions

open access: yesChemPhotoChem, EarlyView.
Mo‐doped BiVO4 photoanodes with TiO2 passivation and Co‐Pi co‐catalyst show enhanced performance under acidic conditions. Mo doping improves conductivity; TiO2 prevents corrosion with stable photocurrent (≈0.3mAcm−2); Co‐Pi enhances OER kinetics, achieving 1.9mAcm−2 at 1.23V_RHE with improved durability, making this system promising for efficient solar‐

On the Method of Harmonic Balance for Lumped‐Element Transformer Models

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...
