New cost-effective silicon carbide high voltage switch created

Researchers at North Carolina State University have created a high voltage and high frequency silicon carbide (SiC) power switch that could cost much less than similarly rated SiC power switches. The findings could lead to ...

Counting down to the new ampere

After it's all over, your lights will be just as bright, and your refrigerator just as cold. But very soon the ampere—the SI base unit of electrical current—will take on an entirely new identity, and NIST scientists are ...

Artificial muscle for soft robotics: Low voltage, high hopes

Soft robots do a lot of things well but they're not exactly known for their speed. The artificial muscles that move soft robots, called actuators, tend to rely on hydraulics or pneumatics, which are slow to respond and difficult ...

Simplifying supersonic nozzle pressure monitoring

A bit of serendipity while carrying out a routine calibration led a researcher at Lawrence Berkeley National Laboratory's (Berkeley Lab) BELLA Center to discover a new method to measure the pressure of supersonic nozzles. ...

Long haul, night repairs for British, US spacewalkers

The first-ever spacewalk on Friday for British astronaut Tim Peake will require a long journey outside the space station to replace a failed power unit while under cover of darkness, NASA said Tuesday.

Researchers develop flexo-electric nanomaterial

Researchers at the University of Twente's MESA+ research institute, together with researchers from several other knowledge institutions, have developed a 'flexo-electric' nanomaterial. The material has built-in mechanical ...

Graphene pushes the speed limit of light-to-electricity conversion

The efficient conversion of light into electricity plays a crucial role in many technologies, ranging from cameras to solar cells. It also forms an essential step in data communication applications, since it allows for information ...
