THE power of transmitting large electric currents is one of the most characteristic properties of metals, and one to which they owe no insignificant fraction of their industrial importance. If we ...

Ultrafast terahertz spectroscopy allows direct insight into the building block of modern magnetic memories. Mainz/Aveiro/Bielefeld/Berlin. Modern magnetic memories ...

Defying conventional scientific knowledge about electrical conductivity, the addition of a common carbon compound to copper to make electrical wires results in significant performance enhancements, ...

For most metals, the relationship between electrical and thermal conductivity is governed by the Wiedemann-Franz Law. Simply put, the law states that good conductors of electricity are also good ...

In an apparent contradiction to textbook physics, a metal has been identified that conducts electricity but produces almost no heat in the process. Such a strange property may be expected to occur in ...

THE discussion at the York meeting of the British Association on the electric supra-conductivity of metals was opened by a reference to the classical experiments of Dewar and Fleming 1 made in 1893 on ...

Copper's role in clean energy initiatives. Issues with copper mining. Possible alternative materials to copper. Copper and the circular economy. Most circuit designers probably aren’t thinking about, ...

Berkeley Lab scientists Junqiao Wu, Fan Yang, and Changhyun Ko are working at the nano-Auger electron spectroscopy instrument at the Molecular Foundry, a DOE Office of Science User Facility. They used ...

Scientists with the University of Chicago have discovered a way to create a material that can be made like a plastic, but conducts electricity more like a metal. The research, published Oct. 26 in ...

Metals are known as good conductors of both heat and electricity. Regardless of temperature or other factors, typical conductivity does not change. This property is known as the Wiedemann-Franz Law.

According to a new study led by scientists at the University of California, Berkeley, electrons in vanadium dioxide can conduct electricity without conducting heat. Vanadium dioxide (VO2) nanobeams ...

In science, there exists a law known as the Wiedemann-Franz Law that states, simply, that most metals that are good conductors of electricity are also good conductors of heat. This law essentially ...
