Nanoaggregates of silica with kaolinite and montmorillonite: Sedimentation and transport

Due to a wide range of applications in industrial fields, engineered nanomaterials (ENMs) have a high potential to enter the soil. The soil's major component of clay likely dictates the fate and transport of ENMs in the subsurface. Currently, few studies are available on the fate and transport of nanoparticle silica (nSiO2) in the presence of clay particles. Therefore, the sedimentation and transport of nSiO2 with two representative clays...
