    Mesoscale modeling of microgel mechanics and kinetics through the swelling transition

    The mechanics and swelling kinetics of polymeric microgels are simulated using a mesoscale computational model based on dissipative particle dynamics. Microgels are represented by a random elastic network subm...

    Frustrated nematic order in spherical geometries

    Coating a spherical colloid with a nematic liquid crystal causes frustration-induced defects in the crystal. The thickness of this coating can be used to systematically control the number and orientation of th...

    Experimental Characterization of the Whip** Instability of Charged Microjets in Liquid Baths

    Capillary liquid flows have shown their ability to generate micro and nano-structures which can be used to synthesize material in the micro or nanometric size range. For instance, electrified capillary liquid ...

    Gravitational compression of colloidal gels

    We study the compression of depletion gels under the influence of a gravitational stress by monitoring the time evolution of the gel interface and the local volume fraction,

    Static light scattering from fractal aggregates of microgel particles

    In this work, we present static light scattering results from clusters formed from mesoscopic gel particles. The resultant I(q) curves show two power law behaviours within the experimentally accessible q window. ...

    Point of zero charge estimation for a TiO2/water interface

    The point of zero charge of a certain commercial titanium dioxide has been determined. This is crucial in determining the colloidal stability that our TiO2/water dispersion exhibits, which greatly influences the ...
