Magnesium is commonly found in rocks and sea water as well as living organisms. Paul Knochel relates how this element has also sparked a great deal of interest among chemists. One of the most ...

Research Institute, the bomb uses magnesium hydride, a silvery powder that stores hydrogen more efficiently than pressurised tanks.

Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape.

Flows involving solid particles are used extensively in the chemical process industries, including areas such as petrochemicals, pollution control, powder technology, coal combustion, and ...

By a suspension, materials scientists mean a liquid in which tiny, insoluble solid particles are evenly distributed. If the concentration of particles in such a mixture is very high, phenomena can ...
