Physicists invent intelligent quantum sensor of light waves

University of Texas at Dallas physicists and their collaborators at Yale University have demonstrated an atomically thin, intelligent quantum sensor that can simultaneously detect all the fundamental properties of an incoming ...

Fighting fungal infections with metals

Each year, more than 1 billion people contract a fungal infection. Although they are harmless to most people, over 1.5 million patients die each year as a result of infections of this kind.

A new road towards spin-polarized currents

The second half of the 20th century was the age of electronics, electronic devices became miniaturized and even more complex, creating problems for their energy consumption and waste heat. Spintronics promises to store or ...

A fresh look at metals reveals a 'strange' similarity

Our theoretical understanding of the way in which metals conduct electricity is incomplete. The current taxonomy appears to be too blurry and contains too many exceptions to be convincing. This is the conclusion that materials ...

Researchers report counterintuitive friction effect

When two metal surfaces slide against each other, a variety of complicated phenomena occur that lead to friction and wear: Small crystalline regions, of which metals are typically composed, can be deformed, twisted or broken, ...

In chemistry, a metal (Greek: Metallo, Μέταλλο) is an element, compound, or alloy characterized by high electrical conductivity. In a metal, atoms readily lose electrons to form positive ions (cations); those ions are surrounded by delocalized electrons, which are responsible for the conductivity. The thus produced solid is held by electrostatic interactions between the ions and the electron cloud, which are called metallic bonds.
