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.

Electrophoresis‐Enhanced Delivery of Rhamnolipid‐Coated Ozone Micro‐Nano Bubbles for Remediating Heterogeneous Aquifer

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Remediating organic pollutants in heterogeneous aquifer presents a significant challenge due to the limited penetration of chemical reagents into these zones. Ozone micro‐nano bubbles, with their small diameters, can transport to low‐permeability zone (LPZ) and oxidize target contaminants; however, their mobility is often hindered by ...

Simulation of Nonpremixed Jet Flame Using Flamelet‐Generated Manifold

Safety Science and Technology, Volume 1, Issue 1, March 2026.
A flamelet‐generated manifold (FGM) approach is proposed and validated by nonpremixed methane jet flames. The effects of radiation and buoyancy were critically examined, and nonpremixed and premixed tabulation methods were compared, revealing the importance of radiation, buoyancy, and appropriate flamelet prototype in accurate FGM modeling.

Soot Formation Mechanisms in Ethylene/N2O Inverse Diffusion Flames: Insights From Dual‐Wavelength LII and SEM Analysis

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Nitrous oxide (N2O), with its self‐pressurizing capability, strong oxidizing potential, and exothermic decomposition, is considered a promising green propellant oxidizer. However, when combined with hydrocarbon fuels, the concurrent formation of soot and polycyclic aromatic hydrocarbons (PAHs) remains a major challenge for propulsion efficiency and ...

Numerical Study on the Influence of CO2 Dilution on Soot Emission in Turbulent Diffusion Flames Impinging on a Cold Surface

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
A flame impinging on a cold surface, frequently utilized in engineering applications, produces a greater amount of soot, which affects health and environmental impacts. The CO2‐diluted turbulent nonpremixed flame impinging on a cold surface is computationally investigated because it is one of the common techniques for reducing emissions.

The Influence of Hydrocarbon Additives on Laminar Burning Velocity and NOx Emissions in Hydrogen‐Air Combustion

Proceedings in Applied Mathematics and Mechanics, Volume 25, Issue 4, December 2025.
ABSTRACT Hydrogen is a promising carbon‐free fuel but faces challenges due to combustion instability and nitrogen oxide (NOx${\rm NO}_x$) emissions during combustion. This study investigates the potential of blending hydrocarbons (methane, propane) or ammonia with hydrogen‐air flames in order to minimize these challenges.

Insight Into Puncture‐Induced Thermal Runaway in Lithium‐Ion Batteries to Reduce Fire Risks in Electric Vehicle Collisions

Battery Energy, Volume 4, Issue 6, November 2025.
This review examines nail penetration‐induced thermal runaway (TR) in lithium‐ion batteries, analyzing experimental and modeling studies on critical factors—battery materials, nail properties, state of charge, and penetration dynamics. It also explores internal short‐circuit modes, TR severity, and safety solutions such as advanced separators, non ...

Ab Initio Study of the Gas‐ and Liquid‐Phase Hydrogen Abstraction From Dimethyl‐, Diethyl‐, and Ethyl–Methyl Carbonates by Ḣ${\dot{\mathrm{H}}} $ and Ċ${\dot{\mathrm{C}}} $ H3 and Subsequent Reactions

International Journal of Chemical Kinetics, Volume 57, Issue 11, Page 652-661, November 2025.
ABSTRACT Dimethyl‐, diethyl, and ethyl–methyl carbonate are important components of lithium batteries. They are used as solvents and comprise the medium through which the lithium ions move between the anode and the cathode during charge and discharge. However, these species are susceptible to decomposition if thermal runaway occurs, forming flammable ...
