Researchers call for renewed focus on thermoelectric cooling

Almost 200 years after French physicist Jean Peltier discovered that electric current flowing through the junction of two different metals could be used to produce a heating or cooling effect, scientists continue to search ...

Shuttering fossil fuel power plants may cost less than expected

Decarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4 issue of ...

New device powers wearable sensors through human motion

The advent of inexpensive wearable sensors that can monitor heart rate and body temperature, as well as levels of blood sugar and metabolic byproducts, has allowed researchers and health professionals to monitor human health ...

Discovery will allow more sophisticated work at nanoscale

The movement of fluids through small capillaries and channels is crucial for processes ranging from blood flow through the brain to power generation and electronic cooling systems, but that movement often stops when the channel ...

A path to new nanofluidic devices applying spintronics technology

Researchers in the ERATO Saitoh Spin Quantum Rectification Project in the JST Strategic Basic Research Programs have elucidated the mechanism of the hydrodynamic power generation using spin currents in micrometer-scale channels, ...
