Photomicrograph showing the result of a NIST nanoscale scratch test on a sample of automobile clearcoat material. The scratch, which shows fractures radiating from the line of impact, is 20 micrometers wide, 150 micrometers long and 2 micrometers deep (A micrometer is a millionth of a meter or about half the length of an average E. coli bacterium.).
