Polyaniline Stabilized Barium Titanate Nanoparticles Reinforced Epoxy Nanocomposites with High Dielectric Permittivity and Reduced Flammability
Epoxy polymer nanocomposites (PNCs) filled with both barium titanate (BaTiO3) (500 and 100 nm) and conductive polyaniline (PANI) stabilized BaTiO3 nanoparticles (NPs) have been successfully prepared. The effects of the BaTiO3 nanofiller loading level and the PANI coating on the mechanical properties, rheological behavior, thermal stability, flammability and dielectric properties w...

[ACS Appl. Mater. Interfaces] Engineering Gold Nanoparticles in Compass Shape with Broadly Tunable Plasmon Resonances and High-Performance SERS
We present the uniform and high-yield synthesis of a novel gold nanostructure of compass shape composed of a Au sphere at the central and two gradually thinning
conical tips at opposed poles. The Au compass shapes were synthesized via a
seed-mediated growth approach employing a binary mixture of
cetyltrimethylammonium bromide (CTAB) and sodium oleate (NaOL) as the
structure-directing agent. Under ...

[Polymer]Lowly loaded carbon nanotubes induced high electrical conductivity and giant magnetoresistance in ethylene/1-Octene copolymers
High electrical conductivity in ethylene/1-octene copolymers (EOCs) was achieved by sticking CNTs onto the gelated EOCs pellet surface and the subsequent hot pressing. The electrical conductivity (s) was observed to be dependent on the pressing temperature and the CNT loading. Variable range hopping (VRH) mechanistic study revealed a 3-d electron transport mechanism. Both uni...

[Physical Chemistry Chemical Physics] Magnetoresistive Polyaniline-Silicon Carbide Metacomposites: Plasma Frequency Determination and High Magnetic Field Sensitivity
The Drude model modified by Debye relaxation time was introduced to determine the plasma frequency (ωp) in the surface initiated polymerization (SIP) synthesized β-silicon carbide (β-SiC)/polyaniline (PANI) metacomposites. The calculated plasma frequency for these metacomposites with different loadings of β-SiC nanoparticles was ranging from 6.11 × 104 to 1.53 × 105 rad s?1. The ...

A high-performance whitelight- emitting-diodes based on nano-single crystal divanadates quantum dots
We report a high-performance phosphors-free white light-emitting-diodes (w-LEDs) using Ba2V2O7 or Sr2V2O7 quantum dots that directly heteroepitaxially grown on common quartz substrates by polymer assisted deposition (PAD). The quantum efficiency of quantum dots is as high as 95%. More importantly, electronic local functions, band structure and partial density of states have b...

Composition controlled nickel cobalt sulfide core– shell structures as high capacity and good ratecapability electrodes for hybrid supercapacitors
Herein, we report a type of core–shell structured NixCo361xS4 (x = 1, 1.5 and 2) through tuning the ratios of Ni to Co by a simple two-step hydrothermal method. Scanning electron microscopy and transmission electron microscopy images of all the Ni–Co sulfides show high porosity and uniform spherical morphology. Moreover, this study demonstrates that controlling the appropriate ratio of Ni to Co ...

High-Performance Simultaneous Two-Photon Absorption Upconverted Stimulated Single-Component Sr2V2O7 Phosphor for White LEDs
Notwithstanding the wide use of white light-emitting diodes (w-LEDs), conventionally consisting of multiple emitting components, some inevitable issues still exist nowadays, such as the intrinsic color balance, device complexity, and high cost associated with such multiple emitting components. We have synthesized simultaneous two-photon absorption upconverted stimulated single-component SrVOphosph...

One-step synthesis of hierarchically porous carbons for high-performance electric double layer supercapacitors
With plenty of unique porous structure at micro-/nano scale, hierarchically porous carbons (HPCs) are
promising for usage in advanced electric double layer supercapacitors (EDLCs) as the electrode materials.
However, wide-range adoption of HPC for practical application is largely shadowed by its extremely
complex synthesis process with considerably low production efficiency. Herein we r...

244. A highly flexible and conductive graphene-wrapped carbon nanofiber membrane for high-performance electrocatalytic applications.
The integration of conventional carbonaceous materials with advanced two-dimensional graphene is a challenging but worthwhile attempt to introduce innovative properties into new composites. Herein, we report a novel and facile strategy to create graphene wrapped electrospun carbon nanofiber (GwC) membranes through the surface-induced assembly of graphene oxide (GO) on the surface of pre-oxidized e...
