Fantastic Plastic
This Catalyst article looks at the use of polymers in the manufacture of household items. The exciting thing about polymers is that it is possible to make polymers behave in so many different ways by organising their long chain molecules in different ways – polymers are the ultimate designer material. The article looks at their…

Plastics Forever?
A Catalyst article discussing how polymers affect every day of people’s lives. With diverse characteristics and applications their usefulness can only be limited by human imagination. Due to polymers’ widespread and varied use a responsible and systematic recycling programme is both economically and environmentally advantageous. This…
Chemistry in a Blast Furnace
A Catalyst article about chemical reactions that occur in a blast furnace during the steelmaking process. This short article features a diagram of a blast furnace showing the active ingredients used to produce iron from ore. This article is from Catalyst: GCSE Science Review 2006, Volume 16, Issue 3. Catalyst is a science magazine…
Iron
A Catalyst article about iron, a relatively abundant element that humans have made widespread use of since the Iron Age (about 750 BC). The article explores the extraction of iron ore, the chemistry of iron and the blast furnace process. This article is from Catalyst: GCSE Science Review 2006, Volume 16, Issue 3. Catalyst is…
Aluminium
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. This article…
Diamonds
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. This article is from Catalyst: GCSE Science…
It's a Material World
A Catalyst article about working in materials science and engineering, the process of deciding which material is best for each application. The structure of materials, processing them and working in jobs and careers with them are explained. This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 3. Catalyst…
