Near zero friction from nanoscale lubricants

more »
Friction hampers the movement of all mechanical parts, including engines for transportation. Scientists built a system with virtually no friction. The system wraps graphene flakes around nanodiamonds that then roll between a diamond-like carbon-surface and graphene on silica.

A team of scientists suggests a solution to the Galactic radioactive plutonium puzzle. All the Plutonium used on Earth is artificially produced in nuclear reactors. Still, it turns out that it is also produced in nature. Plutonium is a radioactive element. Its longest-lived isotope is plutonium-244 with a lifetime of 120 million years.

Nanotube letters spell progress

more »
Researchers test the stiffness of individual nanotube junctions in a new study, and find different characteristics based upon their 'letter' forms. Materials built with particular letters may be useful as building blocks in the construction of macroscale structures, they say.
