Extract

Nano-technology has a lot to contribute toward efforts for a sustainable environment. In addition to the promise of sensors, monitoring devices and functional particles, there is new, fundamental information to begaine d by applying nm-scale measuring techniques to natural materials. Improved understanding of the interaction of fluids with natural solids can lead us to new solutions for some of society’s problems, especially in the realm of clean water and safe treatment of waste. Ultra-high resolution lets us define the molecular-scale processes responsible for uptake of contaminants such as transition metals (e.g. Ni and Cr), radioactive species (e.g. Np) and organic compounds (e.g. glyphosate, a pesticide), while they adsorb on minerals such as calcite and Fe oxides and in some cases, are immobilized by solid-solution formation. With molecular-level resolution, we can see changes that with our traditional methods would only be visible after years or geological time.
