Mopping up gases
We need better ways of capturing carbon dioxide emissions from power stations and industry. And we won’t be using hydrogen cars until we’ve developed practical ways of carrying enough hydrogen gas in the fuel tank. Deanna D’Alessandro’s understanding of basic chemistry led her to create new, incredibly absorbent chemicals that could do both these jobs and much more.
It’s all to do with surface area. Working in California and in Sydney she has constructed crystals that are full of minute holes. One teaspoon of the most effective of her chemicals has the surface area of a rugby field. What’s more, the size and shape of the pores can be customised using light. So she believes she can create molecular sponges that will mop up carbon dioxide, hydrogen, or in theory almost any gas – and then release it on cue.
She used her L’Oréal For Women in Science Fellowship to provide equipment, travel support and a summer vacation student to assist her research.
