The structure was identified by X-ray diffractometer (XRD).
A monoclinic single phase of CuO nanopowder structure was obtained without calcination steps.
Microwave assisted synthesis has not only helped in implementing green chemistry but has also led to the revolution in organic synthesis.
The structure was confirmed by comparison with the Joint Committee on Powder Diffraction Standard (JCPDS) Card File No. 48-1548 [19].
Monoclinic single phase of CuO structure was obtained.

Moreover, the compositions and structures of above substances are simple and easy to prepare.

Electro-chemistry method was used to deposit nanowires in the highly ordered holes of AAO (Anodic Aluminum Oxide).
This is the result of the enhancement of the energy state density, caused by the change of the band structure.
From the images of Fig 5(b), it is apparent that there is a high density of nanowires within the template structure.
