Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Advancing the Co‐Based Anode Catalysts Using Ionomers in Pure‐Water Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
The role of ionomers is investigated in advancing cobalt‐based oxygen evolution catalysts in pure‐water anion exchange membrane electrolysers. Using in situ electrochemical analysis, ex situ material characterization, and membrane potential sensing, it is observed surface reconstruction at high currents and mitigated it via ionomer coating, achieving ...

Kinetic Energy and Complementary Kinetic Energy in Gyrodynamics

Journal of Applied Mechanics, 1993
The concepts of kinetic energy and complementary kinetic energy permit to distinguish between two different formulations of what happens to be the same quantity in Newtonian mechanics. These formulations turn out to play a significant role in gyrodynamics in that they can be used very effectively to establish fundamental equations.
