Use of Nanoparticles in the diagnosis of cancer and treatment of Cancer is being rapidly studied and developed. The present cancer chemotherapy agents are not much selective in differentiating between cancer cells and normal cells and often lead to development of drug resistance and severe side effects. This has prompted the need to study other potential anticancer agents like metallic oxide nanoparticles, with emphasis on their synthesis and application s in the treatment of cancer by designing targeted delivery system to tumour and cancer cells [Vinardell and Mitjans 2015. Nanomaterials, 5, 1004-1021, Valodkar et al 2011. In this review paper an attempt has been made to study various methods of preparation of Copper Oxide Nanoparticles, their characteristics and the detailed microbial activities and anti-cancerous properties of these differently synthesized Copper Oxide Nanoparticles.
The inhibitory action of sesmum indicum oil on the surface of copper metal in 0.5 N HCl using gravimetric and galvanostatic polarization methods has been investigated. The rates of corrosion of copper metal with hydrochloric acid containing sesmum indicum oil were obtained as a function of the oil amount. The inhibitor efficiency was found to depend on the concentration of the sesmum indicum oil. Adsorption of sesmum indicum oil on copper metal was followed the Langmuir adsorption isotherm. The phenomenon of physical adsorption has been proposed on the basis of evaluated thermodynamic parameters.
Electrically conductive CVD diamond having a high thermal diffusivity, when used as an electrode for micro EDM, revealed very low wear compared to copper and Cu-W electrodes in the case of finish EDM condition, where the short pulse duration is adopted. In this research work polycrystalline diamond (PCD), which has a thermal conductivity similar to that of the electrically conductive CVD diamond, is introduced as a new composite electrode material for EDM. Various properties of PCD with respect to EDM of die-steel (SKD11) and tungsten carbide (G5) have been studied and compared with those of the electrically conductive CVD diamond, copper and copper-tungsten electrode materials. It is found that electrode wear and material removal rate decreased with an increase in thermal conductivity depending on the type of the PCD material when very short pulse duration of te=1µs is applied. Extremely low wear, 1/20~1/50 times of the Cu-W electrode in the case of EDM of tungsten carbide workpiece at short pulse duration and zero wear in the case of EDM at short and long pulse duration of SKD11 can be realized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
