Green Energy

Application of nanotechnology which involves the manipulation of materials at the scale of the nanometre to green engineering principles is "Green nanotechnology". Maintaining and improving soil, water, and air quality represent some of the most formidable challenges facing global society in the 21st century. Pollutants from such diverse sources as oil and chemical spills, pesticide and fertilizer runoff, abandoned industrial and mining sites, and airborne gaseous and particulate matter from automobiles exacerbate the situation on a daily basis.
