Well-designed nanostructures of a ternary nanocomposite, graphene/Fe2O3/polyaniline, are fabricated via two-step approach. Graphene oxide is reduced by Fe2+ and well-dispersed loading α-Fe2O3 nanoparticles (20–70 nm in size). A thin film polyaniline situ polymerized on the graphene/Fe2O3 surfaces for fabrication its composite. Among composites obtained at different ratios to polyaniline, graphene/Fe2O3/polyaniline with ratio 2 : 1 exhibits high specific capacitance 638 F g−1 M KOH scan rate...
A ternary electrode material, based on graphene, tin oxide (SnO2) and polypyrrole (PPy) was obtained via one–pot synthesis. The graphene/SnO2/PPy (GSP) nanocomposite is composed of a thin conducting film PPy the surface graphene/SnO2 (GS). An enhanced specific capacitance (616 F g−1) GSP at 1 mV s−1 in M H2SO4 compared with GS (80.2 (523 g−1). shows better cycle stability no obvious decay after 1000 galvanostatic cycles g−1. Its power density energy can reach 9973.26 W kg−1, 19.4 h...
Reduced-graphene oxide/molybdenum oxide/polyaniline ternary composites, RGO(MP), for use as electrode materials high energy density supercapacitors, were firstly synthesized using a one-step method with Mo3O10(C6H8N)2·2H2O and graphene oxide (GO) precursors.

A variety of compounds, including Ni-, Fe-, and Co-containing layered double hydroxides (LDHs), have been explored as catalysts for the oxygen evolution reaction (OER). However, few can meet industrially mandated overpotential 0.30 V at 500 mA/cm2 cell voltage 1.60 V, let alone be applied to electrolysis seawater. We synthesized a nickel foam (NF)-supported NiFe-LDH whose OER is only 0.257 in an alkaline saline solution requires 1.54 same current density when coupled with MoNi4/MoO2/NF...
Electrochemical reduction of carbon dioxide (CO2) to formate is energetically inefficient because a high overpotential (>1.0 V) required for most traditional catalysts. In this work, Bi2O2CO3 (BOC) nanosheets were synthesized as electrocatalysts CO2 the first time. Additionally, BOC decorated on glassy electrode was reduced in situ metal Bi (RB) comparing catalytic performance toward that BOC. The maximum faradaic efficiency 83% at an 0.59 V, which little lower than RB (90% obtained 0.99 V)....
Metal nanoclusters (NCs) as a new type of fluorescent material have attracted great interest due to their good biocompatibilities and outstanding optical properties. However, most the studies on metal NCs focus synthesis, atomic or molecular assembly, whereas ability self-assemble higher-level hierarchical nanomaterials through supramolecular interactions has rarely been reported. Herein, we investigate precise silver (Ag9-NCs, [Ag9(mba)9], where H2mba = 2-mercaptobenzoic acid) peptide DD-5...
Hybridization of single-stranded DNA immobilized on the surface gold nanoparticles (GNPs) into double stranded and its subsequent dissociation ssDNA were investigated. Melting curves rates hybridization measured using fluorescence detection based hybridization-induced change. Two distribution functions, namely state rate distribution, proposed in order to take interfacial heterogeneity account quantitatively analyze data.

In pulsed power systems, metallized film capacitors facilitate the operation of with a relatively small margin to its dc breakdown strength. Electrical conduction in biaxially oriented polypropylene (BOPP) may result leakage high energy density and thus reduction efficiency.
