2-Dimensional layered molybdenum disulfide nanosheets and CTAB-assisted molybdenum disulfide nanoflower for high performance supercapacitor application.

In this study, the supercapacitor performance of the hydrothermal synthesized molybdenum disulfide (MoS) nanosheets and the cetyltrimethylammonium bromide (CTAB)-assisted MoS nanoflower morphology have been investigated. The as-synthesized MoS nanoflower and nanosheet morphology structures were investigated field emission scanning electron microscopy (FESEM), and the internal microstructure was examined high resolution-transmission electron microscopy (HR-TEM) technique. The Fourier transform infrared (FT-IR) spectra were obtained to identify the chemical interaction and the functional groups present in the material.

A SnOQDs/GO/PPY ternary composite film as positive and graphene oxide/charcoal as negative electrodes assembled solid state asymmetric supercapacitor for high energy storage applications.

The work demonstrates tin oxide quantum dots/graphene oxide/polypyrrole (SnOQDs/GO/PPY) ternary composite deposited on titanium foil as a positive electrode and graphene oxide (GO)/charcoal on titanium foil as negative electrode separated by polyvinyl alcohol/potassium hydroxide (PVA/KOH) gel-electrolyte as a solid-state asymmetric supercapacitor for high energy storage applications. Here, tin oxide quantum dots (SnOQDs) were successfully synthesized by a hydrothermal technique, and SnOQDs/GO/PPY ternary composite was synthesized by an method with pyrrole monomer, SnO, and GO. A pH value controlled, which maintained the uniform size of SnOQDs dispersed on PPY, through GO ternary composite was used for fabricating the asymmetric supercapacitor electrode with the configuration (SnOQDs/GO/PPY)/GO/charcoal (85 : 10 : 5).

The role of cobalt doping in tuning the band gap, surface morphology and third-order optical nonlinearities of ZnO nanostructures for NLO device applications.

The work presented here reported the effect of doping cobalt (Co) in ZnO thin films. The thin films were prepared using the spray pyrolysis technique with 0, 1, 5 and 10 wt% cobalt doping concentrations to study the morphological, optical and third-order nonlinear optical (NLO) properties. X-ray diffraction revealed the crystalline nature of the prepared thin films, and the crystallite size was found to increase with the concentration of doped Co.

Flexible and high energy density solid-state asymmetric supercapacitor based on polythiophene nanocomposites and charcoal.

An asymmetric supercapacitor (ASC) was constructed using a polythiophene/aluminium oxide (PTHA) nanocomposite as an anode electrode and charcoal as a cathode electrode. The highest specific capacitance ( ) of the PTHA electrode was found to be 554.03 F g at a current density (CD) of 1 A g and that of the charcoal electrode was 374.

Optical properties and ionic conductivity studies of an 8 MeV electron beam irradiated poly(vinylidene fluoride--hexafluoropropylene)/LiClO electrolyte film for opto-electronic applications.

The influence of 8 MeV energy electron beam (EB) irradiation on optical properties and ionic conductivity of PVDF-HFP/LiClO (90 : 10 PHL10) electrolyte film with 40, 80 and 120 kGy doses. The FT-IR results show that C[double bond, length as m-dash]O bond stretching at 1654 cm is due to the degradation of polymer chains and the CH bond wagging intensity at 1405 cm corresponds to C-H bond scissioning in the 120 kGy dose irradiated film. H and C NMR spectroscopy was performed and the C NMR spectra confirm the effect of EB irradiation of the PHL10 polymer electrolyte by sharpening and splitting the spectral lines with increasing EB dose and revealing a new spectral line at 162.
