Roland Piquepaille writes "Researchers from the Lawrence Berkeley Lab are using nanotechnology to learn how to clean up environmental contaminants like nuclear waste. They are also using supercomputers and state-of-the-art imaging to predict how quickly pollutants react with minerals in soils and aquifers. This article from the Daily Californian says they are studying kinetics, or rates, of reactions which occur at the earthís surface using a nanoscale approach. They started to look at the reactions that take place at the pore scale and plan to expand their scope from nanometers to meters in the months to come. This research has implications for transport of contaminants, especially of radioactive materials, but also for oil or ore recovery. This overview contains more details, references and a picture of a device used to grow and monitor nanocrystals important for our environment."
