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 ...

The new composite prevents malfunctions of electronic devices

Scientists from South Ural State University, in collaboration with colleagues from Belarus, India and China, have created a composite material for nanoelectronics. The material can be used as a dielectric (insulating substance) ...

True holographic movies are within grasp

Holographic movies, like the one R2D2 projected of Princess Leia in "Star Wars: A New Hope," have long been the province of science fiction, but for most of us, the extent of our experience with holograms may be the dime-sized ...

Aerogel: The micro structural material of the future

Aerogel is an excellent thermal insulator. So far, however, it has mainly been used on a large scale, for example in environmental technology, in physical experiments or in industrial catalysis. Empa researchers have now ...

Eggshell-based surgical material for skull injuries

A bioactive polymer-ceramic composite for fixing implants and restoring bone defects in the skull was developed by an international group of materials scientists from the NUST MISIS Center for Composite Materials. An innovative ...

How plantains and carbon nanotubes can improve cars

A luxury automobile is not really a place to look for something like sisal, hemp, or wood. Yet automakers have been using natural fibers for decades. Some high-end sedans and coupes use these in composite materials for interior ...

Composite material

Composite materials (or composites for short) are engineered materials made from two or more constituent materials with significantly different physical or chemical properties which remain separate and distinct on a macroscopic level within the finished structure.
