In this work, the first ZnO/CuO nanocomposites were synthesized by chemical vapour deposition (CVD), thermal evaporation (PVD) and sputtering on silicon substrates (Si). Then, the structural, optical and electrical properties of the samples were investigated. Examination of the X-ray diffraction patterns confirmed the mixed-phase formation of hexagonal zinc oxide (ZnO) and monoclinic copper oxi...
The introduction of defects in graphene will affect the mechanical and electrical properties composite interface. We investigate effect Stone–Wales (S-W), single-vacancy (S-V), double-vacancy (D-V) on interface copper/graphene/copper (Cu/Gr/Cu) sandwich models using first-principles study. results indicate that most forming Cu/Gr/Cu have lower formation energy than free slab. is beneficial to e...
Abstract: Equal channel angular extrusion (ECAE) is a promising technique for production of ultra fine-grain (UFG) materials of few hundred nanometers size. In this research, the grain refinement of aluminium strip is accelerated by sandwiching it between two copper strips and then subjecting the three strips to ECAE process simultaneously. The loosely packed copper-aluminium-copper laminated b...
