Air-Cleansing Poem Fights Pollution Literally and Figuratively

May-18-14 An air-cleansing poster created in collaboration by a team from the University of Sheffield and an award-winning poet can scrub the air of the pollution caused by 20 cars, every day.

The poem, "In Praise of Air," was printed on poster measuring 32 feet wide by 64 feet tall that has been coated with titanium dioxide particles. These particles use sunlight and oxygen to react with the nitrogen oxide pollutants and purify the air. Pro-Vice-Chancellor for Science Professor Tony Ryan, hopes the material, which is inexpensive to create, will spread to flags, billboards and banners—turning " advertisements into catalysts in more ways than one. "

Simon Armitage writes: "I write in praise of air. I was six or five / When a conjurer opened my knotted fist / and I held in my palm the whole of the sky. / I've carried it with me ever since."
