Steel at the Nanoscale (IMAGE) Swansea University Caption Steel seen at the nanoscale. Much of the work of the METaL project, led by Swansea University, is with the steel industry. Steel is a 21st century industry. Using images like this, Swansea University researchers can examine tiny nano-level structures, which are the same length as a human fingernail grows in 1 second. These new steels are now being used to make a new generation of lighter and more efficient cars.
