Synthesis and characterisation of core–shell structures for orthopaedic surgery

Journal of Biomechanics, 2007
This paperwork deals with the obtaining and characterisation of new acrylic cements for bone surgery. The final mixture of cement contains derivatives of methacryloyloxyethyl phosphate, methacrylic acid or 2-acrylamido-2-methyl-1-propane sulphonic acid.

Emulsion polymerization of styrene and DEAEMA with a core-shell structure

Journal of Applied Polymer Science, 2000
Polystyrene–poly(N,N-diethylamino ethyl methacrylate) (PS–PDEAEMA) particles with a core–shell morphology were prepared by seeded emulsion polymerization. Poly(oxyethylene) (POE) (n = 15 and 30) nonyl phenol and sodium lauryl sulfate (SLS) were used as emulsifiers.

Toughening of polyvinylchloride by core–shell rubber particles: Influence of the internal structure of core–shell particles

European Polymer Journal, 2007
Abstract The work focused on the influence of the internal structure of MBS core–shell impact modifiers on the properties of PVC/MBS blends. MBS was synthesized by grafting styrene and methyl methacrylate onto PB seed latex by emulsion polymerization.

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.

The structural properties of GaN/AlN core–shell nanocolumn heterostructures

Nanotechnology, 2010
The growth and structural properties of GaN/AlN core-shell nanowire heterostructures have been studied using a combination of resonant x-ray diffraction, Raman spectroscopy and high resolution transmission electron microscopy experiments. For a GaN core of 20 nm diameter on average surrounded by a homogeneous AlN shell, the built-in strain in GaN is ...

Structure and stability of nickel/nickel oxide core–shell nanoparticles

Journal of Physics: Condensed Matter, 2011
The results of a combined x-ray photoelectron spectroscopy (XPS) and high resolution transmission electron microscopy (HR-TEM) study of Ni nanoparticles (NP), before and after oxidation, are presented. An experimental set-up was realized for the preparation and study of pre-formed NP films, concentrating the attention on Ni NP in the diameter range ...

Core shell structure for solid gas synthesis of LiBD4

Physical Chemistry Chemical Physics, 2010
The formation of LiBD(4) by the reaction of LiD in a diborane/hydrogen atmosphere was analysed by in situ neutron diffraction and subsequent microstructural and chemical analysis of the final product. The neutron diffraction shows that nucleation of LiBD(4) already starts at temperatures of 100 degrees C, i.e. in its low temperature phase (orthorhombic
