Core − shell microgels with controlled structural properties

Polymer International, 2016
Abstract Microgels have gained great attention in the biomedical field for their wide application in diagnostic and drug delivery systems. The bulk properties as well as the surface features of these particular microparticles define their final performance.

Structure of Multiresponsive “Intelligent” Core−Shell Microgels

Journal of the American Chemical Society, 2005
A 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 ...

Magnetic nanoparticles of core–shell structure

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2015
Abstract 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.

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 ...

Structure and Deformations of Pd−Ni Core−Shell Nanoparticles

The Journal of Physical Chemistry B, 2004
Homogeneous collections of Pd-Ni core-shell nanoparticles have been prepared by decomposition of metal-organic compounds and studied by several electron microscopy techniques: transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), high-resolution transmission electron microscopy (HRTEM), energy-filtered microscopy (EFTEM ...

Hydrogel nanonetworks with functional core–shell structure

European Polymer Journal, 2007
Abstract 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.

Assembly and structure of Ni/NiO core–shell nanoparticles

Applied Surface Science, 2012
In this work it is reported a detailed investigation of the structure in Ni/NiO core-shell nanoparticles (NP). An experimental set-up was realized for the preparation and the study of pre-formed NP films. NiO shell was obtained with controlled dosing of O2 gas in the experimental system.

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.

ELECTRORHEOLOGY OF MONODISPERSE CORE/SHELL STRUCTURED PARTICLE SUSPENSIONS

International Journal of Modern Physics B, 2005
As 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,
