ESD geochemists Damien Daval, Giuseppi Saldi, and Kevin Knauss
recently investigated the dissolution of a common silicate (diopside),
and related the bulk dissolution rate with the nanoscale dissolution
rate and surface chemistry of its individual prevalent faces—to
investigate how amorphous silicon-rich surface layers (ASSL) affected
exchanges of matter and energy in the interfacial zone between fluids
and mineral surfaces.
