Nanotechnology offers the potential of novel nanomaterials for the treatment of surface water, groundwater, wastewater, and other environmental materials contaminated by toxic metal ions, organic and inorganic solutes, and microorganisms. Due to their unique activity toward recalcitrant contaminants, many nanomaterials are under active research ...
Nanoengineering is the practice of engineering on the nanoscale. It derives its name from the nanometre, a unit of measurement equalling one billionth of a meter. Nanoengineering is largely a synonym for nanotechnology, but emphasizes the engineering rather than the pure science aspects of the field.
Pedro J.J. Alvarez is the George R. Brown Professor of Civil and Environmental Engineering at Rice University [1], where he also serves as founding Director of the National Science Foundation Engineering Research Center on Nanotechnology-Enabled Water Treatment (NEWT) [2] and as Director of the Rice WaTER Institute [3].
Nanotechnology is the science and engineering of functional systems at the molecular scale. In its original sense, nanotechnology refers to the projected ability to construct items from the bottom up making complete, high-performance products. One nanometer (nm) is one billionth, or 10 −9, of a meter.
Green nanotechnology – use of nanotechnology to enhance the environmental-sustainability of processes currently producing negative externalities. It also refers to the use of the products of nanotechnology to enhance sustainability. Nanoengineering – practice of engineering on the nanoscale.
The environmental impact of nanotechnology is the possible effects that the use of nanotechnological materials and devices will have on the environment. [20] As nanotechnology is an emerging field, there is debate regarding to what extent industrial and commercial use of nanomaterials will affect organisms and ecosystems.
It is being explored to treat ground water, wastewater, soil, sediment, or other contaminated environmental materials. [ 1 ] [ 2 ] Nanoremediation is an emerging industry; by 2009, nanoremediation technologies had been documented in at least 44 cleanup sites around the world, predominantly in the United States.
