Extrinsic Pseudocapacitive NiSe/rGO/g-CN Nanocomposite for High-Performance Hybrid Supercapacitors.

Battery-type materials with ultrahigh energy density show great potential for hybrid supercapacitors (HSCs). In this work, we have developed a nickel selenide (NiSe)/reduced graphene oxide (rGO)/graphitic carbon nitride (g-CN) ternary composite as a promising positive electrode for hybrid supercapacitors (HSCs). The extended π-conjugated planar layers of g-CN promote strong interconnectivity with rGO, which further enhances surface area, surface free energy, and efficient electron/ionic path.

Effect of Oleylamine on the Surface Chemistry, Morphology, Electronic Structure, and Magnetic Properties of Cobalt Ferrite Nanoparticles.

The influence of oleylamine (OLA) concentration on the crystallography, morphology, surface chemistry, chemical bonding, and magnetic properties of solvothermal synthesized CoFeO (CFO) nanoparticles (NPs) has been thoroughly investigated. Varying OLA concentration (0.01-0.

Emergence of Ni-Based Chalcogenides (S and Se) for Clean Energy Conversion and Storage.

Nickel chalcogenide (S and Se) based nanostructures intrigued scientists for some time as materials for energy conversion and storage systems. Interest in these materials is due to their good electrochemical stability, eco-friendly nature, and low cost. The present review compiles recent progress in the area of nickel-(S and Se)-based materials by providing a comprehensive summary of their structural and chemical features and performance.

Evidence of robust 2D transport and Efros-Shklovskii variable range hopping in disordered topological insulator (BiSe) nanowires.

We report the experimental observation of variable range hopping conduction in focused-ion-beam (FIB) fabricated ultra-narrow nanowires of topological insulator (BiSe). The value of the exponent (d + 1) in the hopping equation was extracted as [Formula: see text]for different widths of nanowires, which is the proof of the presence of Efros-Shklovskii hopping transport mechanism in a strongly disordered system. High localization lengths (0.

Sulfur ion concentration dependent morphological evolution of CdS thin films and its subsequent effect on photo-electrochemical performance.

The sulfur ion concentration dependent morphological evolution and its subsequent effect on photo-electrochemical properties of chemically synthesized CdS thin films have been systematically investigated. The plausible growth mechanism for the morphological evolution of CdS thin films due to a change in sulfur ion concentration has been proposed. Scanning electron micrographs (SEMs) reveal that the morphology of CdS thin films has been changed from spherical grains to vertically aligned nanoflakes by systematic control of sulfur ion concentration.
