BOUNDARY ELEMENT METHOD WITH HIGH ORDER IMPEDANCE BOUNDARY CONDITIONS IN ELECTROMAGNETICS

, 2022
In this paper, we study boundary element method with high order impedance boundary conditions (HOIBC) to solve Maxwell's equations. The unknowns are electric and magnetic currents J and M. We propose several formulations and study the existence and uniqueness of the solution.

Engineering MnNiPx Cathode via Dual Role of Mn: Simultaneous Enhancement of Activity and Intermittent Operation Durability

Advanced Functional Materials, EarlyView.
Engineering MnNiPx cathodes through the dual role of Mn simultaneously improves hydrogen evolution reaction activity and intermittent‐operation durability. Mn preferentially oxidizes to protect Ni–P sites from irreversible oxidation, while metallic Mn incorporation enhances the HER kinetics of Ni–P active layer.
