The Material World

BBC Radio 4
on BBC Radio 4 FM

Snowflakes are an example of a crystal formed by nature. Less well-known but still as beautiful are zeolites, nature's molecular sieves. And zeolites aren't just pretty, they're pretty useful too. They help refine 99 per cent of the world's petrol and they make up around a third of the volume in the average packet of washing powder. Quentin Cooper talks to Dervishe Salih from the Davy Faraday
Research Lab about this curious class of molecular cages and how we can grow and use them. Producer Colin Grant
