Unidirectional Crystallization of Charged Colloidal Silica under Temperature Gradient
Submicron-sized charged colloidal particles self-assemble into “crystal” structures in an aqueous medium due to long-range electrostatic interparticle interaction. Since colloidal crystals usually have a Bragg wavelength in the visible-light regime, they have attracted considerable attention as photonic materials. Here, we describe our recent study on the novel crystallization of charged colloi...
متن کاملPair interaction of charged colloidal spheres near a charged wall.
Although equally charged colloidal particles dispersed in clean water are expected to repel each other, an unexplained long-range attraction has consistently been reported for charged colloidal spheres confined by charged macroscopic surfaces. We present an alternative equilibrium measurement of the pair interaction energy for charged spheres near a single charged wall. Analyzing their radial d...
متن کاملNucleation and crystal growth in a suspension of charged colloidal silica spheres with bi-modal size distribution studied by time-resolved ultra-small-angle X-ray scattering.
A suspension of charged colloidal silica spheres exhibiting a bi-modal size distribution of particles, thereby mimicking a binary mixture, was studied using time-resolved ultra-small-angle synchrotron X-ray scattering (USAXS). The sample, consisting of particles of diameters d(A) = (104.7 ± 9.0) nm and d(B) = (88.1 ± 7.8) nm (d(A)/d(B) ≈ 1.2), and with an estimated composition A(0.6(1))B(0.4(1)...
متن کاملCrystallization kinetics of colloidal spheres under stationary shear flow.
A systematic experimental study of dispersions of charged colloidal spheres is presented on the effect of steady shear flow on nucleation and crystal growth rates. In addition, the nonequilibrium phase diagram as it relates to the melting line is measured. Shear flow is found to strongly affect induction times, crystal growth rates, and the location of the melting line. The main findings are th...
متن کاملCrystallization kinetics of polydisperse colloidal hard spheres. II. Binary mixtures.
In this paper we present measurements of the crystallization kinetics of binary mixtures of two different sized hard sphere particles. The growth of the Bragg reflections over time were analyzed to yield the crystallite scattering vector, the total amount of crystal, and the average linear crystal size. It was observed that a particle size distribution skewed to higher sized particles has a les...
