In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy
Journal of Synchrotron Radiation, EarlyView.For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

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.

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor
Applications in Energy and Combustion ScienceClassical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Polymorph‐Specific Electronic Transduction in WO3 during Molecular Sensing
Advanced Materials, Volume 38, Issue 43, 3 August 2026.Metal‐oxide polymorphs with similar surface chemistry can nevertheless exhibit distinct sensing properties. In γ‐ and ε‐WO3, analyte adsorption appears comparable; yet, only ε‐WO3 induces a pronounced lattice electronic perturbation that accommodates charge in sub‐conduction band minimum states.

Effect of Different Acoustic Parameters on NOx Emissions of Partially Premixed Flame
Applied Sciences, 2019 The effects of acoustic frequency (f)/0–400 Hz and amplitude (A)/0–1400 Pa on nitrogen oxides (NOx) emissions of a partially premixed flame were investigated experimentally.
