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.

Energy storage materials built from nano-sized molecular blocks

Molecules of the rare metallic element niobium can be used as molecular building blocks to design electrochemical energy storage materials. Mark Rambaran, Department of Chemistry at Umeå University, presents in his thesis ...

New chemistry happens when dust meets pollution

It is a new chemistry found to take place in a cloud droplet, a wet aerosol, or on the surface of a dust particle. All that it takes to get started is natural events like dust storms, ocean wave action, volcanic eruptions, ...

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.
