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.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
