Integrated hydrogeochemical and microbiological assessment of groundwater quality in a fractured volcanic aquifer, Ibb City, Yemen

Abstract Groundwater quality assessment in fractured volcanic aquifers presents significant challenges due to structural heterogeneity that may influence groundwater flow and contaminant transport. This study presents an integrated hydrogeochemical and microbiological assessment...

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,...
