New method sees fibers in 3-D, uses it to estimate conductivity

As a vehicle travels through space at hypersonic speeds, the gases surrounding it generate heat at dangerous temperatures for the pilot and instrumentation inside. Designing a vehicle that can drive the heat away requires ...

A material that 'bruises' like skin

Human skin bruises when the tissue and muscle in the area suffer trauma or become damaged due to the application of blunt force. However, when an object suffers an impact, it is necessary to examine every inch of the surface ...

Tapping secrets of Aussie spider's unique silk

An international collaboration has provided the first insights into a new type of silk produced by the very unusual Australian basket-web spider, which uses it to build a lobster pot web that protects its eggs and trap prey.

"Better" copper means higher-efficiency electric motors

Researchers at Pacific Northwest National Laboratory (PNNL) have increased the conductivity of copper wire by about five percent. That may seem like a small amount but it can make a big difference in motor efficiency. Higher ...

Stacking and twisting graphene unlocks a rare form of magnetism

Since the discovery of graphene more than 15 years ago, researchers have been in a global race to unlock its unique properties. Not only is graphene—a one-atom-thick sheet of carbon arranged in a hexagonal lattice—the ...
