Dear readers,

The author found some minor corrections in his online published article. The original version of this article unfortunately contained a mistake.

In 2.1 Chemicals: Copper acetate monohydrate was used instead of copper acetate pentahydrate (Cu(CH3COO)2. 5H2O).

In 2.2 CuO nanoparticles preparation: Copper acetate monohydrate  was used instead of copper sulfate pentahydrate (CuSO4.5H2O).

We apologize for these errors.

The original article has been corrected
