Modeling Transport and Charge Effects in Heterogeneous Media
Simulation of charged species reactive transport in complex physically and electrostatically heterogeneous porous media is possible with a multiple continua approach coupled to a geochemical code.
Treating Colloids as Clusters Better Predicts Their Behavior
New research suggests that an accurate prediction of colloidal particle mobilization in the environment should account for the effect of clustering.
