A Catalyst article about aluminium, a shiny silvery metal, which is extracted from its ore by electrolysis. Further addition of other metallic elements results in an alloy, which can be cast into various shapes using moulds. The article looks at the processes of extraction, casting, patterns, moulds and finishing...

A Catalyst article describing how new materials can be designed by studying natural materials and how they work. In particular the development of Velcro, military fabric, swimwear and waterproofing is looked at. These products were developed by scientific study of natural products such as plant burrs, pinecones,...

A Catalyst article about the use of tiny electronic sensors to monitor the movement of people. As electronic devices get smaller and more powerful, they are finding new uses in monitoring human activity. This article describes a project to develop sensors with uses in medicine, sport and electronic gaming.

This Catalyst article is about using computer models which use natural selection to evolve new products. Computers can be used to simulate evolution showing how some species die out and how others evolve and thrive. Products used by humans in everyday activities also evolve and this article describes how their...

A Catalyst article about a brilliant new light source under construction in the heart of the Oxfordshire countryside - the Diamond Light Source. Diamond will be a source of synchrotron light. Many of the everyday commodities people take for granted, from chocolate to cosmetics, from revolutionary drugs to surgical...

A Catalyst article about diamonds. The element carbon exists in a number of allotropic forms, but diamonds have always held a special allure, whether it be for their hardness or for their transparency. The article examines how they can be made artificially and looks at some of their uses.
