A Catalyst article describing how a car's catalytic converter works. A catalytic converter is a part of a vehicle’s exhaust system. It removes harmful substances from the exhaust gases. The article describes what a catalytic converter consists of, the reactions taking place in a car engine and the reactions...

This Catalyst article looks at the Rosetta mission: to rendezvous with Comet 67P/Churyumov-Gerasimenko where it will study the nucleus of the comet and its environment for nearly two years, and land a probe on its surface. The article also describes how gravity assists, also known as slingshot manoeuvres, are used...

This Catalyst article looks at analytical chemists, who are involved in many kinds of testing, including drug testing to catch cheats in sport.

A Catalyst article looking at a day in the life of Charles Darwin at his home in Kent. Much of Charles Darwin’s life after his return from the Beagle voyage was spent at Down House in Kent. He moved here in September 1842 and the article describes the important work such as Darwin’s Theory of Evolution by Natural...

This Catalyst article looks at the process of baking biscuits. All cooking involves chemical reactions but you are not normally aware of them happening. There is an obvious thermal decomposition reaction which takes place in the middle of this recipe – and you get fabulous ginger biscuits at the end.

Paint has been developed and used for thousands of years, allowing artists an increasing range of colours and textures. This article describes the different techniques of developing paint.

This Catalyst article explains how zeolites, sponge-like materials developed from naturally occurring minerals, are used as chemical sieves and as catalysts. Zeolites have incredibly widespread applications. They are used in consumer products such as washing powder and cat litter while many of the petrochemicals...

This Catalyst article looks at how an internal biological clock within every cell of the human body helps to co-ordinate and organise human behaviour and metabolism into approximately 24-hour rhythms – allowing organisms to synchronise with, and anticipate, day and night. When the body clock is disrupted in humans...

This Catalyst article looks at the discovery of the Arctica Islandica, a mollusc which carries a record of past environments in the banding of its shell. In 2006, scientists collecting material from the seabed off the north coast of Iceland found some clam shells which remarkably were found to have come from...

A Catalyst article about the sudden onset of an ice age and whether it is a scientific likelihood. Looking at evaporation, greenhouse gases and thermohaline circulation in the world's ocean currents the article explores likely scenarios for a major drop in temperature.
