Structure of Multiresponsive “Intelligent” Core−Shell Microgels
Journal of the American Chemical Society, 2005A doubly temperature-sensitive core-shell microgel composed of two temperature-sensitive polymers with different lower critical solution temperatures (LCSTs) in the core and shell has been studied by small-angle neutron scattering (SANS). The application of a novel universal form factor model in the analysis of the SANS data reveals that the radial ...

Core-Shell Structured Nanowire Spin Valves
IEEE Transactions on Magnetics, 2010Nanowire based magnetic spin valves utilizing a core-shell device architecture about free-standing Ni nanowires have been fabricated and characterized. Devices containing sequential shell layers of CoO(10 nm)-Co(5 nm)-Cu(5 nm)-Co(5 nm) deposited through sputter deposition around the chemical-vapor-deposited Ni core nanowires exhibit a giant ...

Magnetic nanoparticles of core–shell structure
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2015Abstract This paper describes preparation and characterization of magnetic core–shell nanoparticles with modulated magnetic core diameter and various thickness of the non-magnetic shell. Ag, Au and Cu are used as spacing layer metals. Nanoparticles were fabricated by the synthetic method based on modified seeds.

Triangular core-shell structure Ag@AgAu
2010 Photonics Global Conference, 2010Novel Triangular Ag@AgAu nanoparticles were synthesized in aqueous solution using a seed-mediated approach in the absence of any surfactants. The formation of the gold layer on the silver nanoprism seeds leads to structures with better stability and tunability.

Ag@SnO2 core–shell structure nanocomposites
Chemical Physics Letters, 2007Abstract The synthesis of Ag@SnO 2 nanocomposite particles with core–shell morphology has been reported. Ag colloidal particles were synthesized by a well-documented aqueous reduction technique using NaBH 4 as reductant, trisodium citrate as a stabilizer and AgClO 4 as the source for the Ag 4+ ion.

Mesoporous Microspheres with Doubly Ordered Core−Shell Structure
Chemistry of Materials, 2008The synthesis of doubly ordered core-shell silica based microspheres showing different ordered mesoporous arrangements in core and shell was described. Core mesoporous microspheres were made using an aerosol-assisted process in the presence of nonionic surfactant and the mesoporous shells encapsulating the core microspheres were added to the materials.

Hydrogel nanonetworks with functional core–shell structure
European Polymer Journal, 2007Abstract Nanohydrogel particles of poly(acrylonitrile-co-N-isopropylacrylamide (p(AN-c-NIPAM)) were synthesized using a microemulsion polymerization technique. Highly monodisperse nanohydrogel particles e.g. 50–150 nm, and various morphology such as core–shell and connected beads were obtained.

ELECTRORHEOLOGY OF MONODISPERSE CORE/SHELL STRUCTURED PARTICLE SUSPENSIONS
International Journal of Modern Physics B, 2005As a novel candidate of electrorheological (ER) material, core/shell composite particles (PAPMMA) of poly(methyl methacrylate) (PMMA) core and polyaniline (PANI) shell were prepared and adopted as a dispersed phase. PAPMMA particles, obtained by a dispersion polymerization method, were spherical and possessed a monodisperse particle size distribution,

Highly Porous Core–Shell Structured Graphene-Chitosan Beads
ACS Applied Materials & Interfaces, 2015Graphene oxide (GO) sheets have been assembled into various three-dimensional porous structures and composites, with potential applications in energy and environmental areas. Here, we show the combination of GO and chitosan (CTS) into inorganic-organic heterocomposites as ∼3 mm diameter core-shell beads with controlled microstructure.
