The mechanical non-linear response of dense Brownian suspensions of polymer gel particles is studied experimentally and by means of numerical simulations. It is shown that the response to the application of a constant shear rate depends on the previo

Colloidal Laves phases (LPs) are promising precursors for photonic materials. Laves phases have not yet been observed to form in experiments on colloidal suspensions of hard spheres (HS), even though they have been reported in computer simulations. L

While microgels are in general described as soft particles, polystyrene (PS) microgels can be synthesized in a way that cross-link density has only a minor influence on their physical properties. Even though the particles swell in a good solvent, the

In previous work of our group on the re-entrant melting of colloidal glasses we observed an unexpectedly huge re-entry region for a binary system of 1:50 crosslinked polystyrene (PS) microgel spheres when a depletion attraction range ξ = Rg,polymer/

We report on two novel and improved reaction strategies for the synthesis of a recently introduced new colloidal model system [M. Wiemann, R. Schneider, E. Bartsch, Z. Phys. Chem. 226 (2012) 761] composed of cores of the highly fluorinated polymer po

Polystyrene (PS) microgel colloids have often been used successfully to model hard sphere behaviour even though the term “gel” invokes inevitably the notion of a more or less soft, deformable object. Here we systematically study the effect of red

In this work, the evaluation of a newly developed anionic polymerizable surfactant (surfmer), viz., sulfonated 3-pentadecyl phenyl acrylate, in the emulsion polymerization of styrene and its effect on the polymer properties is reported. The results w

The holographic grating relaxation technique also known as forced Rayleigh scattering consists basically in writing a holographic grating in the specimen of interest and monitoring its diffraction efficiency as a function of time, from which valuable

Synthesis of colloidal particles which are sterically stabilized in water and at the same time isorefractive in aqueous dispersion has been achieved by copolymerizing a fluoracrylate monomer with a PEG-macromonomer. Colloidal stability against salt a
