Multiscale physicochemical evolution of mined coal links structure transport and reaction kinetics during thermochemical conversion

Global reliance on coal for energy generation and chemical production necessitates physics-based frameworks that move beyond empirical bulk characterization toward predictive and sustainable utilization strategies. Coal is a heterogeneous, reactive porous medium whose structure,...

Esophagopericardial fistula secondary to battery acid ingestion in a 3-year-old boy: a case report

Abstract Background Esophagopericardial fistula (EPF) is an extremely rare and life-threatening condition associated with a high mortality rate, particularly when diagnosis and intervention are delayed. Here we present the case of a 3-year-old boy who developed EPF secondary to a...
