Superconductors: Resistance is futile

Every standard cable, every wire, every electronic device has some electric resistance. There are, however, superconducting materials with the ability to conduct electrical current with a resistance of exactly zero – at ...

How growing cities can support at-home electric vehicle charging

Rapid urban population growth is driving many cities around the world to reduce their carbon footprints. In Canada, two major policy agendas are designed to achieve this: boosting urban density and promoting low-carbon transportation ...

Materials chemists tap body heat to power 'smart garments'

Many wearable biosensors, data transmitters and similar tech advances for personalized health monitoring have now been "creatively miniaturized," says materials chemist Trisha Andrew at the University of Massachusetts Amherst, ...

Researchers capture an image of negative capacitance in action

For the first time ever, an international team of researchers imaged the microscopic state of negative capacitance. This novel result provides researchers with fundamental, atomistic insight into the physics of negative capacitance, ...

New class of solar cells, using lead-free perovskite materials

Lead-based perovskites are promising materials for low-cost and high-efficiency solar cells. However, the intrinsic instability and the toxicity of lead (Pb) have raised serious concerns of the viability of Pb-based perovskites, ...

In search of Weyl semimetals

Imagine how much you could accomplish if the circuits in your laptop and cell phone worked 10 times faster, and your battery lasted 10 times longer, than they do now.

Light up logic: Engineers perform computational logic with light

For the first time, researchers have performed logic operations with a chemical device using electric fields and ultraviolet light. The device and the pioneering methods open up research possibilities, including low-power, ...

Neutrinos become less and less mysterious

The authors of a study published in Physical Review D have shown that coherent neutrino scattering with nuclei provides a novel way to measure the neutrino charge radii. This interaction was theoretically predicted more ...

How to fund roads and ensure electric vehicles pay their share

Since electric vehicles use no gasoline, their drivers pay no gasoline tax. And as more people drive EVs, gas-tax revenue for road repairs is dwindling. So how can California and the rest of the country avoid road-funding ...
