Low Stretched Premixed Methane-Air Flame.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1997 A numerical study of low stretched premixed methane-air flame in a counterflow configuration is conducted. The present simulation includes detailed transport properties and chemical kinetics. It is found that near the flammability limit, there is a radiation extinction branch in addition to the normal stretch extinction branch, which has been ...

From Single Atoms to Nanoparticles: Pathways Toward Efficient and Durable Pt/TiO2 Photocatalysts
Advanced Functional Materials, EarlyView.Platinum single atoms on TiO2 nanosheets evolve into clusters and nanoparticles under ethanol photoreforming and thermal treatments. By controlling deposition and post‐treatments, particle size and location on specific facets are modulated. The study reveals how stability pathways determine efficiency, guiding the design of more durable photocatalysts.
