“…Nickel oxides with different morphologies such as nanoparticles, [9] nanofibers, [10] nanotubes, [11] nanowalls, [12] nanoshafts, [13,14] nanocones, [15] nanoflakes, [16][17][18] nanostructure hierarchical spheres, [19] and mesoporous structures [20] have been previously studied. In addition, nickel oxide composites with different carbon structures such as carbon coatings, [21,22] carbon nanotubes, [10,23] conducting polymers, [24,25] and graphene [26][27][28] In this work, we used an optical floating zone furnace to synthesize cubic-shaped NiO nanocrystals. This novel synthesis method has been reported in our recent publication.…”

Energy, 58 (September), 707-713.The effects of FEC (fluoroethylene carbonate) electrolyte additive on the lithium storage properties of NiO (nickel oxide) nanocuboids AbstractNanocuboid shaped NiO (nickel oxide) has been synthesized using an optical floating zone furnace. It was found that the nanocuboids exhibit single crystalline nature, and have clean and sharp edges. Furthermore, the NiO nanocuboids were tested for their electrochemical performances as anode material for LIBs (lithium-ion batteries) in a coin-type half cell. The effects of FEC (fluoroethylene carbonate) additive on the lithium storage performance were also investigated, which is the first of such studies for transition metal oxides. It was found that FEC has a positive effect on the cycling stability and also improves the rate performances of the nanocuboids. The capacity recorded at 0.1C (100mAg-1) after 50 charge/dischargecycles is 1400mAhg-1. Lastly, the NiO nanocuboids can achieve very high rate capability of 12C (12Ag-1) AbstractNanocuboid shaped nickel oxide has been synthesized using an optical floating zone furnace.It was found that the nanocuboids exhibit single crystalline nature, and have clean and sharp edges.

“…The nanocomposites prepared through in situ polymerization tend to exhibit enhanced thermal stability as compared to PUR polymer. The significant enhancement of thermal stability by incorporating the inorganic phase into the polymer matrix is attributed to the strong interfacial interactions between the polymer and inorganic fillers [25,26]. …”

Electrically conducting hybrid composites of poly(3-methoxythiophene) (PMOT) and nickel oxide (NiO) (PMOT-NiO) were synthesized by chemical oxidative method with their different proportions. The synthesized PMOT-NiO nanocomposites were characterized for optical, structural, and electrical analysis. Transmission electron microscope (TEM) depicts the morphology of the samples which revealed the transformation of thread morphology of PMOT to the clusters in PMOT-NiO hybrid composites. The structural and optoelectronic properties of hybrid composites were quite different from those of pure PMOT and NiO nanoparticles which were attributed to the chemical interaction between PMOT and NiO nanoparticle. X-ray diffraction (XRD) confirmed the cubic structure of NiO with an average crystallite size of 5 nm. The nanocomposites had lower diffraction peak intensities and smaller interplanar spacing as compared to NiO. Ultraviolet (UV) spectra and fluorescence spectra (PL) showed that the optical behavior of nanocomposites was far superior to PMOT and NiO separately. FTIR spectra revealed that the absorption of PMOT was affected by the presence of NiO nanoparticle. The roomtemperature electrical conductivity was increased up to 4.2× 10 −7 Ω/cm −1 with increase in the concentration of NiO content in PMOT-NiO hybrid composites.

Abstract. The basic concepts of electrodes and electrochemical cells (including both galvanic and electrolytic ones) are introduced and illustrated with practical examples. Particular attention is paid to negative electrodes in primary and secondary cells, fuel cell electrodes and electrodes in redox flow batteries. General features and arguments pertaining to selection, optimization and further development are highlighted.
