A levitated nanosphere as an ultra-sensitive sensor

Sensitive sensors must be isolated from their environment as much as possible to avoid disturbances. Scientists at ETH Zurich have now demonstrated how to remove from and add elementary charges to a nanosphere that can be ...

Synthetic skin could aid wound healing

Engineers have devised a fabric dressing whose thickness and elasticity can be custom-matched to specific areas of the body.

How to ice-proof the next generation of aircraft

35,000 feet is standard cruising altitude for a commercial jet airplane, but at those lofty heights the air temperature plummets below -51 degrees Celsius and ice can easily form on wings. To prevent ice formation and subsequent ...

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 ...

X-ray imaging reveals secrets in battery materials

In a new study, researchers explain why one particular cathode material works well at high voltages, while most other cathodes do not. The insights, published in the 19 June issue of the journal Science, could help battery ...

Remote high-voltage sensor unveiled

Ever since the first human placed a bare hand on an uninsulated electric line, people have refrained from personally testing energetic materials. Even meters made of metal can melt at high voltages.

Keeping tabs on aging power cables to prevent outages

Switzerland's power grid comprises over 250,000 kilometers of lines. Composed of a transmission and a distribution network, the voltage is gradually reduced from 380,000 to 230 volts enroute to the consumer. The aboveground ...
