Novel numerical model simulates folding in Earth"s crust throughout the earthquake cycle
Earth's crust is constantly in motion. As tectonic plates that make up the lithosphere shift, pulling apart and crashing into each other, the crust fractures and folds in response. Both faulting and folding play out at fault-bend folds, which are cre.....»»
Development of a single-process platform for the manufacture of graphene quantum dots
Graphene consists of a planar structure, with carbon atoms connected in a hexagonal shape that resembles a beehive. When graphene is reduced to several nanometers (nm) in size, it becomes a graphene quantum dot that exhibits fluorescent and semicondu.....»»
