Nanotechnology is the study and manipulation of materials on a nanometer scale (billionths of a meter). Materials of this size have different chemical and physical properties than bulk materials. Nanomaterials are useful for many things because of their properties, such as cleaning water. Researchers and engineers are using nanomaterials to create better filtration systems and …

Processing materials at the nanoscale (billionths of a meter) is the focus of nanotechnology. At this scale, materials have several characteristics that make them different from materials at larger scales. By exploiting these qualities, new materials and technologies can be developed with improved functionality and performance. Nanotechnology is applied to environmental protection, creating advanced technologies …
