Predicting the Stability and Mobility of Engineered Nanomaterials Following Release into the Subsurface Environment Academic Article uri icon

abstract

  • The increasing prevalence of nanotechnology in commercial applications and devices carries with it the potential release of engineered nanomaterials into the environment. Subsequently, the stability and mobility of these nanomaterials in soils and groundwaters will determine their ability for long-range transport through the environment and into drinking water supplies. Recently, there has been significant interest in the integration of CdSe nanoparticles and other types of nanocrystals into photovoltaic devices due to their unique nanoscale optical properties. Current demand for the development of alternative energy sources has prompted us to focus on the synthesis of CdSe nanocrystals within a 1-10 nm range and their transfer into aqueous media via a ligand exchange procedure. The stability of CdSe nanoparticles electrostatically stabilized with mercaptoundecanoic acid was …
