Fate and Transport of Molybdenum Disulfide Nanomaterials in Sand Columns.

Research and development of two-dimensional transition metal dichalcogenides (TMDC) (e.g., molybdenum disulfide [MoS]) in electronic, optical, and catalytic applications has been growing rapidly.

Effects of solution chemistry on the transport of graphene oxide in saturated porous media.

A transport study was performed in saturated porous media through a packed bed column to simulate fate of graphene oxide nanoparticles (GONPs) in the subsurface environment. Transport experiments, along with mass balances and column dissections, were conducted as a function of ionic strength (IS, 10(-3)-10(-1) M). Additionally, an extensive evaluation of the electrokinetic properties and hydrodynamic diameters of GONPs were determined as a function of IS and pH.
