Sea shells inspire better building materials

Seashells have done an exemplary job of protecting their inhabitants for around a hundred million years, so perhaps it isn’t surprising that scientists and chemists have now replicated their unique structure in a manmade material. Taking inspiration from shells, researchers from the University of Manchester and the University of Leeds have successfully reinforced calcium carbonate, or chalk, with polystyrene particles such as those used in disposable drinking cups. Their achievement could lead to stronger building and bone replacement materials, or other practical applications.
