Gas turbine blades of conventional rotorcraft turboshaft engines are optimized to operate at nearly a fixed speed and a fixed incidence angle. If the operating condition of the engine changes, then the flow...

Researchers from the National University of Singapore (NUS) are trying to solve the problem of plastic waste by converting it into something useful: Aerogels.

Tissue repair following injury or during surgery is conventionally performed with sutures and staples, which can cause tissue damage and complications, including infection....

Most metals, with the notable exception of gold, tend to oxidize when exposed to air and water. This reaction — which produces rust on iron, tarnish on silver, and verdigris on copper or...

Motion capture (Mocap) is a technique used in the film industry to digitally track a human actor's movements and precisely transfer those motions to an animated figure. But it has other applications as...
