3. Influence of Core–Shell Rubber Particles Synthesized with Different Initiation Systems on the Impact Toughness of Modified Polystyrene
Core–shell poly(butadiene-graft-styrene) (PB-g-PS) rubber particles were synthesized with different initiation systems by emulsion grafting polymerization. These initiation systems included the redox initiators and an oil-soluble initiator, 1,2-azobisisobutyronitrile (AIBN). Then the PB-g-PS impact modifiers were blended with polystyrene (PS) to prepare the PS/PB-g-PS blends. In ...

(Au@Ag)@Au double shell nanoparticles loaded on rutile TiO2 for photocatalytic decomposition of 2-propanol under visible light irradiation
We synthesized (core@shell)@shell ((Au@Ag)@Au) nanoparticles (NPs) by a multistep citrate reduction method for utilization as photosensitizers of TiO2. The (Au@Ag)@Au NPs exhibited strong photoabsorption in visible light response due to LSPR excitation of the Ag shell, and its LSPR characteristics were stable under visible light irradiation for a long time because oxidation of the Ag shell was pre...

Plasmonic enhanced dye-sensitized solar cells with self-assembly gold-TiO2@core–shell nanoislands.
Decorating TiO2 photoanode of dye-sensitized solar cell (DSSC) with silver or gold nanoparticles has been shown to be an effective approach for enhancing device performance via the plasmonic effects. Here, we show for the first time that the same approach can be adopted simultaneously for both the photoanode and the counter-electrode of a DSSC but operates with different enhancement mechanism. I...

(ECS Solid State Lett.) Microwave Assisted Formation of Magnetic Core-Shell Carbon Nanostructure
This letter describes a facile high temperature microwave assisted process to form the magnetic core-shell carbon nanostructure from polyaniline (PANI)-magnetite (Fe3O4) nanocomposites. The amorphous combined with graphitized carbon shell is observed by the transmission electron microscopy (TEM). The crystalline metallic iron, cementite, Fe3O4 and iron oxide (Fe2O3) are observed in the magnetic ...

(EST) One-pot Synthesis of Magnetic Graphene Nanocomposites Decorated with Core@Double-shell Nanoparticles for Fast Chromium Removal
A facile thermodecomposition process to synthesize magnetic graphene nanocomposites (MGNCs) is reported. High-resolution transmission electron microscopy and energy filtered elemental mapping revealed a core@double-shell structure of the nanoparticles with crystalline iron as the core, iron oxide as the inner shell and amorphous Si–S–O compound as the outer s...

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 ...

【ACS Appl. Mater. Interfaces】Fluorescent pH Sensor Based on Ag@SiO2 Core–Shell Nanoparticle
We have demonstrated a novel method for the preparation of a fluorescence-based pH sensor by combining the plasmon resonance band of Ag core and pH sensitive dye (HPTS). A thickness-variable silica shell is placed between Ag core and HPTS dye to achieve the maximum fluorescence enhancement. At the shell thickness of 8 nm, the fluorescence intensity increases 4 and ...

【Langmuir】A Facile Interfacial Reaction Route To Prepare Magnetic Hollow Spheres with Tunable Shell Thickness
Magnetic Fe3O4 hollow spheres were successfully synthesized with a water in oil in water (W/O/W) emulsion. During the facile procedure, no high pressure, high temperature, or other complex reaction conditions were required.Transmission electric microscope (TEM) images showed that all the hollow structural products have a good spherical morphology with an average diameter of 160 nm. The aver...

Single Emulsion Microfluidic Production of Janus and Core-Shell Particles via Off-chip Polymerization
In this work, we describe a straightforward approach to produce monodisperse Janus and core-shell particles by using organic solvent free single emulsion droplet-based microfluidic device combining with off-chip polymerization. To accomplish this, methyl methacrylate (MMA) was used as both the oil phase and solvent to dissolve a polymerizable PEG-based macromolecular surfactant, instead of t...
