    Abstract: Mercury is recognized internationally as an important pollutant since mercury and its compounds are persistent, bioaccumulative and toxic, and pose human and ecosystem risks. A critical aspect of mercury cycling is its bioaccumulation, mainly as methylmercury, along the contaminated water with mercury resulting in high risk of human. Adsorption of ... Show More

    Abstract: The 2-phenylbenzothiazole derivatives have antitumor activities. Work has shown that these derivatives have mesomeric forms. The electrophilic centers of these mesomers form adducts with the nucleophilic centers of deoxyribonucleic acid (DNA). These adducts destroy the tumor cells and prevent the proliferation of these. In this sense, the knowledge... Show More

    Abstract: The effect of polycrystallite surface engineering on the time required to fully hydrogenate green chitosan-mediated CuO to form hydrogenated chitosan-mediated CuO (H-Cht-CuO) as well as the catalytic properties of both CuO and H-Cht-CuO have been investigated. The prepared chitosan mediated CuO was obtained from the reaction of copper (II) sulphate... Show More
