Description

Application

• Impact of temperature on the physicochemical, structural and biological features of copper-silica nanocomposites.: This study investigates how temperature variations affect the properties of copper-silica nanocomposites. The research focuses on the physicochemical and structural changes that occur and their subsequent impact on biological applications. The findings provide valuable insights for the development of advanced materials with tailored properties for specific applications (Dulski et al., 2020).


• H(2)O(2)-assisted photoelectrocatalytic degradation of Mitoxantrone using CuO nanostructured films: Identification of by-products and toxicity.: This article explores the degradation of Mitoxantrone, a chemotherapy drug, using copper oxide nanostructured films in a photoelectrocatalytic process assisted by hydrogen peroxide. The study identifies the by-products formed during degradation and assesses their toxicity. The research highlights the potential of CuO nanostructured films in environmental remediation and pharmaceutical waste management (da Rosa et al., 2019).
