Assessment of antimicrobial efficacy of leather coating using chitosan modified TiO-CuO nanocomposites.

This research investigates the microbial inactivation potential of ternary TiO-CuO-chitosan nanocomposites (TCC NCs) applied as surface coatings on cowhide leather. Initially, bare TiO nanoparticles (NPs) and binary TiO-CuO (TC) NCs, with varying CuO NPs content, were prepared using an sol-gel method. These binary TC NCs were then modified with chitosan at varying weight percentages (2%, 4%, 6%, and 8%).

Square-Facet Nanobar MOF-Derived CoO@Co/N-doped CNT Core-Shell-based Nanocomposites as Cathode Materials for High-Performance Supercapacitor Studies.

The binary as well as ternary nanocomposites of the square-facet nanobar Co-MOF-derived CoO@Co/N-CNTs (N-CNTs: nitrogen-doped carbon nanotubes) with Ag NPs and rGO have been synthesized via an easy wet chemical route, and their supercapacitor behavior was then studied. At a controlled pH of the precursor solution, square-facet nanobars of Co-MOF were first synthesized by the solvothermal method and then pyrolyzed under a controlled nitrogen atmosphere to get a core-shell system of CoO@Co/N-CNTs. In the second step, different compositions of CoO@Co/N-CNT core-shell structures were formed by an method with Ag NPs and rGO moieties.
