Diamonds are a Scientist's best Friend: Research into Building Better Small Machines Do diamonds really last forever? That's the hope of University of Wisconsin-Madison researchers who are trying to solve the problems associated with building extremely small machines and having them withstand the test of time, wear and tear.The problem is that these machines are so small - microscopic or smaller - that their moving parts cannot be assisted by lubricants; instead, they have to function in a dry state, like a car with no oil.A really, really small car with no oil.
