Shear stiffness and friction mechanics of single-layer graphene measured for the first time
Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many ...
Tighter 'stitching' makes better graphene
(Phys.org) -- Similar to how tighter stiches make for a better quality quilt, the "stitching" between individual crystals of graphene affects how well these carbon monolayers conduct electricity and retain ...
