摘要： A method of forming a highly textured tenorite film includes providing a substrate in a pulsed electrophoretic deposition (PEPD) reactor. Tenorite microcrystals, de-ionized water, hydrogen peroxide and sulfuric acid are mixed in the PEPD reactor. A temperature of the PEPD reactor is adjusted to 2-15° C. The highly textured tenorite film is formed on the substrate by electrophoresis having electrophoretic parameters. The electrophoretic parameters include a pulse ON time having a duration of 10 ms to 500 ms, a pulse duty cycle having a range of 0.1 to 0.23, a pulse height having a range of 0.1 to 0.8 kilovolts, and a deposition time having a range of 70 minutes to 2.5 hours.

摘要： The copper oxide nanoparticles synthesized using Rhatany root extract involves preparing the Rhatany root extract by adding powdered Rhatany roots to boiling water, allowing the mixture to soak overnight, and removing any solid residue by filtering to obtain the aqueous extract. The copper oxide nanoparticles are prepared by mixing equal volumes of the aqueous Rhatany root extract and 0.1 M aqueous copper sulfate, heating the mixture at 80° C. for 40 minutes, and adding 1 M sodium hydroxide dropwise to the mixture to precipitate CuO. The precipitate is removed by centrifuge, washed with ethanol, dried, and calcined at 400° C. for 4 hours to obtain the copper oxide nanoparticles. The resulting nanoparticles proved effective in degrading wastewater dyes, showed anticancer activity against human cervical cancer by cell viability assay, and showed antibacterial activity against various strains of bacteria by agar diffusion.
