Abstract: Abstract The concept of the spatial wettability gradient is applied to bulk porous media to passively influence directional spontaneous imbibition flow. The imbibition process in an oil-bearing medium was mathematically modeled and experimentally validated for… read more here.

Abstract: The determination of the speciation of ions and molecules in supercritical aqueous fluids under pressure is critical to understanding their mass transport in the Earth’s interior. Unfortunately, there is no experimental technique yet available to… read more here.

Abstract: The observation that primitive arc magmas are more oxidized than mid-ocean-ridge basalts has led to the paradigm that slab-derived fluids carry SO2 and CO2 that metasomatize and oxidize the sub-arc mantle wedge. We combine petrography… read more here.
