Enhancing Bubble Removal in Geometry‐Optimized Electrodes

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
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.

H2‐Driven Whole‐Cell Conversion of Diamines to N‐Heterocycles by Recombinant Cupriavidus necator

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
A Cupriavidus necator chassis couples a diamine oxidase–imine reductase cascade with an H2‐driven soluble hydrogenase cofactor module to convert linear diamines into saturated N‐heterocycles in vivo, using H2 as the sole source of reducing power.

Composite dilution effect of exhaust gas recirculation and lean-burn on combustion and emissions of oxyhydrogen/bio-isopropanol/gasoline ternary fuel engine

Frontiers in Energy Research
The complementary utilization of oxyhydrogen and bio-isopropanol in carbon-neutral fuel engines can effectively enhance power output and combustion stability. However, oxyhydrogen blended combustion results in an increase in NOx emissions.
