A team of U.S. scientists has discovered that by tightly packing molecules, they could obtain nanothin sheets of materials showing surprising strength. As one enthusiast researcher says, “It’s an amazing little marvel.” The team adds that “even when suspended over a tiny hole and poked with an ultrafine tip, the membrane boasts the equivalent strength of an ultrathin sheet of plexiglass that maintains its structural integrity at relatively high temperatures.” This could lead to highly sensitive pressure sensors in precision technological applications. read story
