Ion Structure Near a Core-Shell Dielectric Nanoparticle

Physical Review Letters, 2017
A generalized image charge formulation is proposed for the Green's function of a core-shell dielectric nanoparticle for which theoretical and simulation investigations are rarely reported due to the difficulty of resolving the dielectric heterogeneity.

Core–shell nanohydrogel structures as tunable delivery systems

Polymer, 2007
Abstract Poly(acrylonitrile- co - N -isopropylacrylamide) (p(AN- co -NIPAM)) core–shell hydrogel nanoparticles were synthesized by microemulsion polymerization and their feasibility as a drug carrier was investigated. Highly monodispersed nanoparticles with desired size range – i.e., 50–150 nm – were prepared by adjusting the reaction conditions. The

Core–Shell Structured PEO-Chitosan Nanofibers by Coaxial Electrospinning

Biomacromolecules, 2012
Core-shell structured PEO-chitosan nanofibers have been produced using a coaxial electrospinning setup. PEO and chitosan solutions, both in an aqueous acetic acid solvent, were used as the inner (core) and outer (shell) layer, respectively. Uniform-sized defect-free nanofibers of 150-190 nm diameter were produced.

Self-organization of core-shell and core-shell-corona structures in small liquid droplets

Applied Physics Letters, 2011
It was recently discovered that core-shell and core-shell-corona microstructures in immiscible liquid alloys, which were previously obtained only in outer space, can be fabricated under gravity condition on earth using conventional gas atomization. The origin was attributed solely to Marangoni motion driven by temperature-dependence of interfacial ...

Magnetorheology of synthesized core-shell structured nanoparticle

IEEE Transactions on Magnetics, 2005
The composite particles with polymeric core particles covered by Fe/sub 3/O/sub 4/ (magnetite) shell were synthesized in order not only to reduce the density of the particle but also to extend its applicability into biological system using magnetic nanoparticles. The magnetorheological (MR) characteristics of the composite suspension were investigated.

Paramagnetic microspheres with core–shell-ed structures

Journal of Materials Science, 2012
Paramagnetic microspheres with core–shell-ed structures were successfully synthesized by electroless plating technique. The surface morphology and core–shell-ed structures of the paramagnetic microspheres were examined by scanning electron microscopy as well as optical microscopy.

Dielectric Composites Containing Core@shell Structure Particles

Advanced Materials Research, 2011
The composites with high permittivity and low dielectric loss were obtained. The fillers were the core@shell structure of the self-passivated aluminum (Al) particles (denoted as Al@Al2O3). The Al2O3 interface between Al and polymer matrix played important role in tailored dielectric properties of composite.

Core-Shell Structured Nanocomposites with Electromagnetic Properties

Advanced Materials Research, 2013
The electromagnetic nanocomposites with a core-shell structure are synthesized by in situ chemical oxidative polymerization. The Co doped Fe3O4magnetic particles (Co-Fe3O4) act as the core and poly (3,4-ethylenedioxythiophene)-poly (sodium-p-styrenesulfonate) (PEDOT-PSS) as the conductive polymer shells.
