New study gives insight into graphene grain boundaries

(Phys.org)—Using graphene – either as an alternative to, or most likely as a complementary material with – silicon, offers the promise of much faster future electronics, along with several other advantages over the ...

Nanocrystals not small enough to avoid defects

(Phys.org)—Nanocrystals as protective coatings for advanced gas turbine and jet engines are receiving a lot of attention for their many advantageous mechanical properties, including their resistance to stress. However, ...

Rare meteorites created in violent celestial collision

A tiny fraction of meteorites on earth contain strikingly beautiful, translucent, olive-green crystals embedded in an iron-nickel matrix. Called pallasites, these "space gems" have fascinated scientists since they were first ...

New type of 'space weathering' observed on asteroid Vesta

The surface of the giant asteroid Vesta is weathering in a way that appears to be completely different from any other asteroid yet visited, according to new data recorded by NASA's Dawn spacecraft. This new type of space ...

Every atom counts in graphene formation

(Phys.org)—Like tiny ships finding port in a storm, carbon atoms dock with the greater island of graphene in a predictable manner. But until recent research by scientists at Rice University, nobody had the tools to make ...

Organic compounds found in proto-planetary disks

(PhysOrg.com) -- A new study from scientists in the US has reported that organic compounds could be formed in proto-planetary disks, and could have seeded the development of life in our own and other planetary systems.
