Material tested that can make a human prosthetic last for more than 150 years. Nanotubes were coated with nanoparticles of zirconia and, in order for this to be effected, the nanoparticles were heated beyond their boiling point (hydrothermal synhtesis). This process, say researchers, creates a prosthesis material that can hold up for 10 times longer inside the body than is possible with today's materials. Prosthetics made from today's materials must be replaced every 10 to 15 years.
