Ignition of a rectangular solid by an external heat flux

, 1994
The influence of corners on the ignition of a solid exposed to a surface energy flux is analyzed with large activation energy asymptotics. We begin with the analysis of the ignition of semi-infinite wedges by a constant heat flux.

Inundation and Sediment Supply Predict Annual but Not Centennial Carbon Accumulation in Tidal Wetlands Across Land‐Use Types

Global Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Despite growing interest in the contributions of tidal wetlands to natural climate solutions, data remain scarce on how land use affects their carbon accumulation rates (CAR). Additionally, environmental factors driving the large observed variability in CAR among sites are poorly understood.

Effect of compression ratio and exhaust gas recirculation on spark assisted compression ignition combustion under different proportions of methanol gasoline

Case Studies in Thermal Engineering
Spark-assisted compression ignition (SACI) is gaining popularity as a way to help achieve carbon neutrality. While most existing research focuses on gasoline SACI, investigations on alcohol-blended fuels are scarce.
