Making jet engines (and power generation) more efficient

It’s very hard to set up a jet engine in a wind tunnel and get accurate measurements inside it while it’s rotating 7,000 times a minute.

So while other members of the University of Melbourne’s mechanical engineering department use wind tunnels to measure turbulence on the surface of airplanes, Professor Richard Sandberg has developed a computer program to make the same measurements inside an engine.

His work also applies to the turbines used to generate power from gas, wind and wave.

From sea snails to electronic free circuits

Sea snails and sponges are shedding light on how to create electronic-free circuitry and environmentally friendly optical fibre, say Geelong scientists.

The structure of a sea snail’s mother-of-pearl layer suggests how to channel light.

Inspired by the materials these sea creatures make, an Australian-US team is trying to create 3D gold nanoparticle arrays that channel light.

“Effectively we are creating circuitry without electronics,” says Tiffany Walsh, Veski Innovation Fellow and one of the researchers from Deakin University.
