Drawing the line between explosion and collapse in electron-capture supernovae

Astronomy & Astrophysics
Context. Electron-capture supernovae (ECSNe) are commonly thought to result in a collapse to a neutron star. Recent work has shown that, under certain conditions, a thermonuclear explosion is also a possible outcome. The division between the two regimes,

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.

STUDY OF THE EFFECT OF ELEVATED PRESSURES ON THE LAMINAR BURNING VELOCITY OF PROPANE-AIR MIXTURES

Diyala Journal of Engineering Sciences, 2015
Laminar burning velocities were obtained for three specific equivalence ratios of propane –air mixtures (Ø= 0.8, 1.0 & 1.3). The effect of elevated pressures at variable initial temperatures was also analyzed.

Selective Electrochemical NOx Reduction to N2 for Sustainable Ammonia Energy Systems

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Selective electrochemical NOx reduction to N2 offers a promising route to mitigate combustion‐derived NOx emissions in ammonia energy systems. This Perspective links *NO‐mediated pathways, the key intermediate role of N2O, and low‐coverage limitations to the origins of limited N2 selectivity, establishing tandem catalysis and microenvironment ...
