The U.S. Department of Energy has awarded the Tucson nanotechnology company, Ridgetop Group Inc., with a $100,000 contract for monitoring experiments.

The Phase I Small Business Innovation Research grant is for developing prognostics, or tests that predict the remaining useful life of electronics, for networks in nuclear physics experiments, the company announced Monday.

In May, Ridgetop was among hundreds selected for multibillion-dollar U.S. Navy contracts.
