“…[126][127][128] Both CuO and Cu 2 O have been proved to transform into Cu nanoparticles and Li 2 O when reduced by lithium, [129][130][131][132] and the latter is generally observed as an intermediate both upon discharge and charge of a battery containing the former. [ 131 , 133,134 ] As a matter of fact, certain cycling ineffi ciencies have been observed for CuO, which result in the presence of Cu 2 O after a full dischargecharge cycle.…”

Despite the imminent commercial introduction of Li-ion batteries in electric drive vehicles and their proposed use as enablers of smart grids based on renewable energy technologies, an intensive quest for new electrode materials that bring about improvements in energy density, cycle life, cost, and safety is still underway. This Progress Report highlights the recent developments and the future prospects of the use of phases that react through conversion reactions as both positive and negative electrode materials in Li-ion batteries. By moving beyond classical intercalation reactions, a variety of low cost compounds with gravimetric specific capacities that are two-to-five times larger than those attained with currently used materials, such as graphite and LiCoO(2), can be achieved. Nonetheless, several factors currently handicap the applicability of electrode materials entailing conversion reactions. These factors, together with the scientific breakthroughs that are necessary to fully assess the practicality of this concept, are reviewed in this report.

Copper Oxide/Carbon (CuO/C) nanocomposites were developed through the green method using the leaf extract of Adhatoda vasica at room temperature. Here, the leaf extract serves as a capping agent, reducing agent and a source of carbon for the formation of nanocomposites. As we know, this is the first article on the synthesis of CuO/ C nanocomposites using this leaf extract. The nanocomposites were prepared by mixing the copper sulphate pentahydrate solution with the plant extract under certain conditions. The synthesized material was characterized by XRD, UV-Visible, FTIR, FE SEM, EDS, XPS and TGA. The results revealed that the synthesized material is a composite of copper oxide and functionalized graphene-like carbon. The SEM images indicated that the CuO/C nanoflakes had an average thickness of 7-11nm. Further, the composites were examined for antifungal activity and antibacterial activity. The nanocomposites showed significant antibacterial activity against the pathogenic bacterial strains Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Staphylococcus aureus and antifungal activity against the fungi Aspergillus niger and Candida albicans. Also, the Minimum Inhibitory Concentration (MIC) and Minimum Fungicidal/Bactericidal Concentration (MFC/MBC) of the nanocomposites were determined against the fungus C. albicans and the bacteria K. pneumonia.

The investigation aims at the synthesis of copper oxide nanoparticles (CuO Nps) using Gloriosa superba L. plant extract as fuel by solution combustion synthesis, their characterization and studies on antibacterial activities against selected pathogenic bacteria. Xray diffraction studies showed that the particles are monoclinic in nature. The UV-visible absorption spectrum of CuO Nps indicates the blue shift with increase of concentration of plant extract. SEM images reveal that the particles are spherical in nature. TEM image indicates that as-formed CuO Nps are spherical in shape, and the size is found to be in the range 5-10 nm. Further, as-formed CuO Nps exhibit significant antibacterial activity against pathogenic bacterial strains namely Gram −ve Klebsiella aerogenes, Pseudomonas desmolyticum, and Escherichia coli, Gram +ve bacteria Staphylococcus aureus. The current study demonstrates convenient utilization of Gloriosa superba L. extract as a fuel for the efficient synthesis of CuO nanoparticles through a green synthesis method to obtain significantly active antibacterial material.
