Atomic Force Microscopy (AFM) has been used to observe the dissolution of (001) cleavage surfaces of barite (BaSO4) in deionized water and in solutions of DTPA (diethylene triamine pentaacetic acid), a synthetic metal-ion ...
Previously published microscopic observations of the heterogeneous oxidation of Mn(II) at hematite and albite surfaces were used to develop rate expressions that model the changes in solution composition during oxidation ...
