Multi‐Phase Heterostructured NiMoN Nanoflower as Bifunctional Separator Coatings for High‐Performance Lithium–Sulfur Batteries

Battery Energy, Volume 5, Issue 5, September 2026.
NiMoN nanoflowers are introduced as multifunctional separator coatings for Li–S batteries. The dual‐metal nitride structure offers strong polysulfide adsorption, accelerated redox kinetics, and enhanced Li+ transport. Compared to NiN and Celgard, NiMoN achieves superior cycling stability, lower capacity fading, and excellent rate performance ...

In‐situ asphaltene capture with iron oxide nanoparticles in steam‐assisted gravity drainage (SAGD) for improved recovery and partial upgrading of bitumen

The Canadian Journal of Chemical Engineering, Volume 104, Issue 9, Page 4787-4808, September 2026.
Key improvements obtained by incorporating nanoparticles into a lab‐scale SAGD process configuration. The bar plots show enhanced oil recovery, reduced viscosity, and increased asphaltene adsorption in nanoparticle‐assisted scenarios compared with conventional SAGD.

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.

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 flue gas recirculation rates on low‐NOx combustion characteristics: A numerical simulation based on the combustion process of a gas boiler

The Canadian Journal of Chemical Engineering, Volume 104, Issue 8, Page 3970-3983, August 2026.
Abstract NOx emissions from gas boilers severely impact the environment, and flue gas recirculation (FGR) technology can effectively reduce such emissions, yet the effects of different FGR rates on combustion performance and NOx formation remain unclear. This study thus used numerical simulation (via ANSYS Fluent, adopting the realizable k‐ε turbulence

Waste‐to‐Energy Transformation: Performance and Emission Analysis of Diesel–Plastic–Vegetable Fuel Blends

Engineering Reports, Volume 8, Issue 8, August 2026.
DPV blends produced from waste plastic pyrolysis oil and vegetable oils deliver higher engine efficiency and lower emissions compared to diesel. The optimized B60‐PSO blend improves BTE by 12% and reduces BSFC, CO, NOx, and soot, supporting sustainable, circular‐energy solutions.

Combustion analysis by image processing of premixed flames [PDF]

Proceedings 2000 International Conference on Image Processing (Cat. No.00CH37101), 2000
We describe a three-step algorithm for the analysis of color images of flames, with the objective of analyzing the combustion process and its control parameters indirectly. The algorithm first extracts the interesting regions, applying a clustering method in the RGB color space, identifying and eliminating irrelevant regions and applying morphological ...
