    copper. copper: [OE] A major source of copper in the ancient world was the Mediterranean island of Cyprus, so the Romans called it cyprium aes ‘metal of Cyprus’. This became cuprum in late Latin, from which it was borrowed into prehistoric West and North Germanic as *kupar, source of Old English coper. (Copper the slang term for ‘policeman’ [19] is ...

    2020-11-25 · Molybdenum (Mo) and tungsten (W) doping in copper vanadate (Cu 3 V 2 O 8) gives important insights into the modulation of carrier mobility and charge separation efficiency. Mo and W atoms have more valence electrons than vanadium(V), providing extra electrons to the host lattice of Cu 3 V 2 O 8 (CVO) resulting in raising the Fermi level wherein impurity energy levels will act as donors.

By varying the grain size between 5 and 50 nanometers, we show that the flow stress and thus the strength exhibit a maximum at a grain size of 10 to 15 nanometers. This maximum is because of a shift in the microscopic deformation mechanism from …
