Hard materials: Carbon nitride for tribological application

Carbon nitride is an attractive material for its expected hardness of the hypothetical compound β-C3N4. On the other hand, amorphous carbon nitride (CNx) exhibits a low friction coefficient under certain conditions, a property ...

A tiny grain helps reveal the history of a rock

Researchers can use the mineral rutile to learn about rock types and their history. Two articles published in the highly respected journal Geology now present a new application of a method for more easily tracing the mineral ...

Engineering thin-film oxide interfaces

(Phys.org)—Research at the U.S. Department of Energy Office of Science's Advanced Photon Source (APS) provides new insights about a material that might form the basis for an alternative to conventional silicon-based semiconductor ...

Ultrashort laser ablation enables novel metal films

Laser ablation is well known in medical applications like dermatology and dentistry, and for more than a decade it has been used to vaporize materials that are difficult to evaporate for high-tech applications like deposition ...
