Thanks for reading, we’ll be back in the New Year and hope to see you then!
Merry Christmas and a Happy New Year from all at Chemistry World! We’re off until the New Year now so thought we’d leave you with this seasonal micro-snowman.
Frosty, here, stands 30µm tall and is made out of balls of tin etched using an ion beam. His nose is a blob of platinum 700nm wide and the parts were assembled using an atomic force microscope. If you want to learn more about how Dave Cox at the UK’s National Physical Laboratory made the snowman then check out his page.
