Document Summary
Nanomaterials are on a scale between 1 to 100 nanometers. The characteristics we see at the nanoscale will be moribund when looking out of. It will behave like a conventional material this scale. We look at this particular scale because we can apply their interactions with the scale extremes. There are different properties of nanoparticles, such as the gold nanoparticle. 1 nm gold nanoparticles are brown-yellow with melting point 700 degrees. 20 nm gold nanoparticles are red with mp about 1000. 100 nm gold nanoparticles are purple-pink mp about 1000. Nanoparticles are used in things such as clothes, technology, sports equipment, and so. They are used to enhance the materials. Nano-scaled zno sunscreen appears clear, while the large zno particles will appear. Spf protects you from the sun, and the spf number corresponds to how many minutes white you will be protected from the sun. The magic of nanomaterials in not new, nature has has nanomaterials for as long as.
