Water as a metal

Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used ...

Chaotic electrons heed 'limit' in strange metals

Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established by the laws of quantum ...

Under pressure, 'squishy' compound reacts in remarkable ways

Remarkable things happen when a "squishy" compound of manganese and sulfide (MnS2) is compressed in a diamond anvil, say researchers from the University of Rochester and the University of Nevada, Las Vegas (UNLV).

A new chromium complex emits light in elusive NIR-II wavelength

Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium ...

Thumb-sized device quickly 'sniffs out' bad breath

No one wants bad breath—not when visiting friends and family, at a job interview, and especially not on a first date. Smelly breath can make things awkward, but it also is a natural warning sign, indicating that serious ...

Bacteria enlisted in French push for rare earths autonomy

As Europe seeks to reduce its reliance on China for the rare earth metals needed for modern batteries and electronics, French researchers have found a potentially potent ally: bacteria that can help extract the elements from ...

Metal

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.
