Not a drag: breakthrough will create cleaner, faster planes

(PhysOrg.com) -- A world first model for predicting fluid flows close to surfaces will enable engineers to reduce drag in vehicles, and in turn, lead to more efficient and greener planes, cars and boats, according to a University ...

Self-healing surfaces

The engineers' dream of self-healing surfaces has taken another step towards becoming reality -- researchers have produced a electroplated layer that contains tiny nanometer-sized capsules. If the layer is damaged, the capsules ...
