Journal ArticleDOI
Magnetic silica dispersions: preparation and stability of surface-modified silica particles with a magnetic core
Journal ArticleDOI
Preparation of monodisperse, fluorescent PMMA-latex colloids by dispersion polymerization.
Gilles Bosma,Chellapah Pathmamanoharan,Els H.A. de Hoog,Willem K. Kegel,Alfons van Blaaderen,Henk N. W. Lekkerkerker +5 more
TL;DR: A single step procedure to prepare monodisperse colloidal poly(methyl)methacrylate (PMMA) particles where fluorescent dyes are incorporated into the polymer network, which are sterically stabilized against flocculation by poly(12-hydroxystearic acid).
Journal ArticleDOI
Preparation and Properties of Optically Transparent Aqueous Dispersions of Monodisperse Fluorinated Colloids
Gijsberta H. Koenderink,Stefano Sacanna,Chellapah Pathmamanoharan,M. Raşa,Albert P. Philipse +4 more
TL;DR: In this article, the emulsion polymerization and seeded growth of negatively charged, monodisperse fluorinated latex spheres in water with radii in the range 50−700 nm were reported.
Book ChapterDOI
Controlled (seeded) growth of monodisperse sterically stabilised magnetic iron colloids
TL;DR: Modified polyisobutene and oleic acid appear to be very effective stabilisers for iron colloids formed by thermolysis of iron pentacarbonyl in decalin this paper.
Journal ArticleDOI
Determination of the Saturation Adsorption Density of Paramagnetic Ion-Complexes on Colloïdal Silica by NMR Field-Cycling Relaxation Spectroscopy.
TL;DR: In this paper, the authors measured the magnetic field dependence of the proton spin-lattice NMR relaxation time (referred to as nuclear magnetic relaxation dispersion) to determine the number of ions, either free in solution or adsorbed onto the surface in aqueous colloidal silica suspensions.
