Continuous impinging in a two-stage micromixer for the homogeneous growth of monodispersed ultrasmall Ni–Co oxides on graphene flakes with enhanced supercapacitive performance

A two-stage microimpinging stream reactor (TS-MISR) strategy that combines a first homogeneous premixing stage with a subsequent microimpinging stream reacting stage has been constructed for the controllable synthesis of Ni–Co–O/RGO composites.
