(Phys.org) —Italian materials scientist Nicola Pugno has realized amazing gains in adding toughness to fibers by twisting them into slip knots resulting in materials that can take far more abuse before breaking than those ...
(Phys.org) —Sometimes, all it takes is an extremely small amount of material to make a big difference. Scientists at Argonne National Laboratory have recently discovered that they could substitute one-atom-thick graphene ...
