Enhancing Bubble Removal in Geometry‐Optimized Electrodes

Advanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion

A Combinatorial Study on Hydrogen Separation Membranes

, 2018
Metallic membranes among the hydrogen separation membranes are quite attractive due to their very high hydrogen selectivity and hydrogen permeability. The efforts in metallic membranes generally concentrate on to identify membrane compositions which have a high hydrogen permeability with a reduced cost. Among the metallic membranes, Pd and Pd alloys, i.
