Effect of the Concentration of Copper on the Properties of Copper Sulfide Nanostructure
...Show More Authors

Nanoparticles of copper sulfide have been prepared by simple reaction between using copper nitrate with different concentrations ratio 0.1, 0.3, and 0.5 mM, thiourea by a simple chemical route. The prepared Nano powders have been deposited onto glass substrates by casting method at 60°C. The structure of the product Nano- films has been studied by x-ray diffraction, where the patterns showed that all the samples have a hexagonal structure of covellite copper sulfide with the average crystalline sizes 14.07- 16.51 nm. The morphology has been examined by atomic force microscopy, and field emission scan electron microscopy. The AFM images showed particles with almost spherical and rod shapes with average diameter sizes of 49.11- 90.64 nm. From the UV-Vis absorption studies, it has been noted that the increased absorption edge for all thin films leads to decreases in the energy gap of 3.5 to 3.0 eV for 1mM and 5mM respectively.

Social Satire in Harold Pinter’s Celebration
...Show More Authors

Harold Pinter was one of the most important dramatists in the modern and the
contemporary age. Pinter presented his own dramatic realm in which he turns the theatre into
a moral institution. He employed the elements of several schools of drama and manipulated
them in order to deliver his ethical messages emphasizing the necessity to regain and renew
the world's morality in order to face the political and social injustices committed against
humanity. His writings developed over more than fifty years in style, techniques and his
interests. However, his main concern was his social and political satire.
