By 2030, the aging US population will need over 500,000 hip implants each year. This image shows a cobalt and chromium alloy used in these implants. Images like these help researchers study defects which can lead to corrosion and break down in hip replacements. This sample of the metal alloy is only 100 nanometers thick – 100 times thinner than a human hair. At this microscopic scale, we can see variations in the metal’s crystal structure (here, the black, curving lines show where the sheet is bending). Studying these metals in detail helps researchers design better biomaterials and safer, longer-lasting implants.
