This is an article on the center for materials science, the National Bureau Standards (NBS). From ceramic tiles that shield the space shuttle to dental adhesives which replace metal fillings, new materials are revolutionizing technology and everyday life. NBS is at the forefront of materials technology with its broad-based research effort conducted by the Center for Materials Science (CMS). The Center provides measurements, data, standards, reference materials, and other technical information regarding materials to industry, government agencies, universities, and other scientific organizations. CMS research supports development of new and improved materials which can be used safely, efficiently, and economically.
