Effect of HBr on Explosion Limits of Stoichiometric Hydrogen‐oxygen Mixture

International Journal of Chemical Kinetics, Volume 58, Issue 9, Page 646-657, September 2026.
ABSTRACT This work, based on numerical simulations, discusses the effect of HBr as an inhibitor on the explosion limit of stoichiometric hydrogen‐oxygen gas mixture in a closed spherical vessel. The numerical simulation solves the complete governing equations for mass, momentum, species and energy.

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.

A Comparative Study of Litchi‐chinensis Biodiesel–Diesel Blends With Alcoholic and Nanoparticle Additives on Engine Performance, Emissions, and Coefficient of Friction

Energy Science &Engineering, Volume 13, Issue 11, Page 5154-5171, November 2025.
ABSTRACT Environmental hazards and the growing demand for fossil fuels are two major current concerns. The current global situation requires extensive research on renewable fuels. In this experimental study, we investigated different blends of biodiesel derived from litchi seed oil, which is inedible, for engine performance, emissions, and tribological
