Xenon - a stranger in search of strange particles

Xenon is a noble gas that turns up in various lights, gets used in xenon ion propulsion systems for spacecraft & plays a key role in the search for dark matter, says Prof Allan Blackman from AUT in ep 92 of Elemental.

Vanadium - Model T Fords, big batteries & sea squirts

Vanadium makes steel stronger & lighter, is being used in what will be the world's largest battery, and sea squirts are full of it, says Prof Allan Blackman from AUT in ep 91 of Elemental.

09:21

Tantalum - a tantalising chemical element

The metal tantalum is usually found with the element niobium, has a very high melting point but is a 'conflict mineral', says Prof Allan Blackman in ep 80 of Elemental.
