The heterojunction based on plasmonic metals of Ag and Cu in the oxide form was synthesized and decorated carbon nanotubes to form Ag-CuO/MWCNTs nanocomposites via a pulsed laser ablation process for water treatment. This study presents the synthesis and characterization of Ag/MWCNTs nanocomposites with different amounts of CuO NPs using a novel two-step pulsed laser ablation technique for enhanced photocatalytic degradation of Congo Red dye under UV-visible-light irradiation. Structural and optical characterization techniques confirmed the successful formation of highly pure and crystalline nanocomposites, and the coupling of Ag NPs with CuO NPs significantly enhanced visible-light absorption, making the nanocomposites highly effective for photocatalytic applications, which were systematically evaluated under varying pH, catalyst dosage, dye concentration, and irradiation time conditions.

To a great extent, characterization has depended on the differences in the peak positions of both tissues in addition to the overall profile which exhibits a distinctive sharp adipose peak in the case of a normal breast. In many excised tissue samples, breast cancer samples may be mixed with a variable percentage of other tissues which affect the shape of the x-ray-scattering profile and consequently the ability to characterize the tissue.
