The image above illustrates the micrometer-scale ballistic study of multilayer graphene led by UMass Amherst mechanical and industrial engineer Jae-Hwang Lee. Graphene–an atomic monolayer of carbon atoms arranged in a honeycomb lattice–is known for its outstanding mechanical strength. Lee and his research colleagues at Rice University provide the first experimental demonstration that graphene is 10 times more effective than steel in the protection against a supersonic projectile (Science). They show that a bullet’s kinetic energy can be transferred far beyond the impact area, enabling highly efficient bulletproofing performance. Lee’s Nano-Engineering Laboratory is designing metamaterials for a wide-range of energy, defense, and bio applications through 2D/3D nano-structuring of polymers, metals, and other materials.
