Study shows graphene able to withstand a speeding bullet

(Phys.org)—A team of researchers working at Rice University in the U.S. has demonstrated that graphene is better able to withstand the impact of a bullet than either steel or Kevlar. In their paper published in the journal ...

How tiny cracks lead to large-scale faults

The geological and topographical features that make up the world we live in are shaped in large part by faults and fractures in Earth's brittle crust. Faults arise from preexisting microscopic imperfections within rock. When ...

Nanostructured ceramic coatings do not fatigue, finds study

Extremely thin ceramic coatings can completely change the properties of technical components. Coatings are used, for example, to increase the resistance of metals to heat or corrosion. Coating processes play a role for large ...

Self-healing concrete could multiply lifespans of structures

Researchers at Worcester Polytechnic Institute (WPI) are using an enzyme found in red blood cells to create self-healing concrete that is four times more durable than traditional concrete, extending the life of concrete-based ...
