Transport of Surface-modified Carbon Nanotubes through a Soil Column10:26

Transport of Surface-modified Carbon Nanotubes through a Soil Column

9.9K
Surface properties of a nanoparticle are important for their interaction with the surrounding medium. Therefore the surface modification of carbon nanotubes can be critical for their transport and retention through porous media. Here, lab scale column experiments are used to understand the possible transport and retention of these nanoparticles.
