Protective gas-masks are extremely helpful in many emergency situations, but they’re usually the size and shape of a small, unwieldy animal. But all that is about to change because Cornell student Jennifer Keane has been working with the school’s Textiles Nanotechnology Laboratory to create a lightweight fabric hood and mask that do the same thing as a gas mask but come in a much lighter and smaller package. The innovative high-tech clothing uses clustered crystalline compounds known as metal organic framework (MOF) molecules to trap nano-size gases such as carbon monoxide.
