The National Institute of Standards and Technology has developed three ASTM International standard test methods for the thin films used to make micromachines (MEMs). Published in The Annual Book of ASTM International Standards, the test procedures—first such standards in the world—could faciliate global commerce in MEMs by enabling reliable measurements of MEMs devices. Detailed instructions are given for measuring thin-film dimensions and strain. For more info, go to www.eeel.nist.gov/812/test-structures.
Automakers are on the prowl for lighter weight materials to make vehicles less heavy and more fuel efficient, and Nanosteel is one of the companies hoping to take advantage of this opportunity with their lightweight automotive steel of the same name.
