The mathematical definition of 'nano' is one billionth; so for example, a nanosecond is one billionth of a second. Nanotechnology is the science of manufacturing and utilizing extremely small particles and devices, sometimes as small as single atoms and molecules. A nanometer is one-billionth of a meter, which is approximately 80,000 times thinner than a human hair. Nanomaterials include carbon nanotubes used in electronics, body armor and cancer treatments, nanoclays which are used in composite materials, and nanoscale metals, alloys, and oxides, used in the energy and renewable energy industries.
