Preserving pine forests by understanding beetle flight

The mountain pine beetle is one of the main causes of tree mortality in the pine forests of North America. For example, the insect has killed thousands of acres of pine forest in British Columbia and Alberta, and as a result, ...

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 ...

Magnetic materials: Forging ahead with a back-to-basics approach

Scientists have recently started to explore the possibility of using an intrinsic property of the electron known as spin for processing and storing information. Magnetic fields can influence the dynamics of electron spin, ...

Ultra-high-strength metamaterial developed using graphene

New metamaterial has been developed exhibiting hundreds of times greater strength than pure metals. Researchers from KAIST have developed a composite nanomaterial. The nanomaterial consists of graphene inserted in copper ...
