Unweaving a rainbow – Transparent materials and refractive indices

It is axiomatic that nothing can move faster than light, but it is worth remembering that this is only true for propagations in vacuo. In all natural transparent materials the...

Rubber revolution - Chronicling the beginnings of the rubber industry

Vulcanised rubber is one of the most widely used and important materials. In 1857, a book by Thomas Hancock introduced the manufacturing process to Europe. He worked closely with Charles Macintosh and studied samples of Charles Goodyear’s vulcanised rubber.

Chinese burn - Reviewing the Chinese coal industry

China's coal industry has risen to the challenge of powering what is predicted to become the world’s largest economy. The sector's unique structure sees conflict between large state-owned mines and a myriad of small mines operating on a local authority or private basis. It is also influenced by rising demand for coal in non-mining areas and the desire by the Government to cap electricity prices, reduce exports, focus coal to the domestic industries and keep prices under control.

Fuelling cost reductions - novel polymer could cut fuel cell costs

A new polymer could lead to cheaper fuel cells. ElectroPhen is a thermoset polymer, whose polymerisation generates nanostructures of conductive pathways. For bipolar plate applications, graphite is used as the filler.

Virtual mining leads the way - Computer modelling software
