We've all heard that diamonds are a girl's best friend, but in her hip? Yes. University of Alabama physics professor Yogesh Vohra used a chemical vapor-deposition process to bond diamond particles onto a metal surface, which creates a smooth coating that is resistant to wear. Those properties make it a candidate for use in artificial hip bones. The diamond film has a hardness value of about 80% of that of a perfect crystalline diamond. Vohra received a patent for the process and uses thereof. For more information, call (205) 934-6662.
