Naturally adhesive

Until now most adhesives have been manufactured from petroleum-based materials. However, they can also be obtained from renewable raw materials -- for example from proteins, natural rubber, starch, or cellulose. Fraunhofer ...

Smart anti-icing system for rotor blades

In very cold climate zones, the wind can blow with tremendous force. But wind turbines have rarely been built in these regions up to now. The risk of ice formation on the rotor blades is just too high. But now, an energy-efficient ...

Smart helicopter thanks to active rotor blades

Active systems in helicopter rotor blades can adapt the blades' aerodynamic properties to local airflow conditions. The use of such systems leads to lower fuel consumption, increased maximum speed and reduced noise and vibration. ...

Researchers discover new mechanism behind cellular energy conversion

Researchers from Mount Sinai School of Medicine have enhanced our understanding of the mechanism by which cells achieve energy conversion, the process in which food is converted into the energy required by cells. This groundbreaking ...

Spirit Rover: Rear Wheel Trouble Continues

(PhysOrg.com) -- Results of diagnostic tests on Spirit's right-rear wheel on Sol 2109 (Dec. 8, 2009) continue to indicate a troubled wheel, which may leave the rover with only four operable wheels.

Improved control of big power in little motors

Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems—but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories.

Finding instead of searching

It is easy to lose track of things in large storage facilities but not at the wind turbine manufacturer Enercon's facility in Magdeburg though, where a positioning system with digital inventory management increases transparency ...
