An approach is proposed which allows to self-consistently calculate the structural and the thermodynamic properties of highly charged aqueous colloidal suspensions. The method is based on the renormalized jellium model with the background charge distribution related to the colloid-colloid correlation function. The theory is used to calculate the correlation functions and the effective colloidal...

Abstract We characterise the local mechanical properties of two-dimensional colloidal crystals with hexagonal symmetry assembled at flat interface between oil and water. Our experiments elucidate conditions under which material behaves isotropically, as opposed to those where microstructure plays a major role. Brownian fluctuations are used extract stiffness lattice continuum approximation, whe...

Lead-free copper halide perovskite nanocrystals (NCs) are emerging materials with excellent photoelectric properties. Herein, we present a colloidal synthesis route for orthorhombic Cs2CuCl4 NCs well-defined cubic shape and an average diameter of 24 ± 2.1 nm. The exhibited bright, deep blue photoluminescence, which was attributed to the Cu(II) defects. In addition, passivating by Ag+ could effe...

Within the framework of the mode coupling theory (MCT) of structural relaxation, mechanisms and properties of non-ergodicity transitions in rather dilute suspensions of colloidal particles characterized by strong short-ranged attractions are studied. Results building on the virial expansion for particles with hard cores and interacting via an attractive square-well potential are presented, and ...

Attractive colloidal particles are trapped in metastable states such as colloidal gels at high attraction strengths and attractive glasses and high volume fractions. Under shear such states flow via a two step yielding process that relates to bond and cluster or cage breaking. We discuss the way the structural properties and related stress response are affected by the shear rate. At low rates c...

We investigated the origin of birefringence in colloidal films of spherical silica particles. Although each particle is optically isotropic in shape, colloidal films formed by drop drying demonstrated birefringence. While periodic particle structures were observed in silica colloidal films, no regular pattern was found in blended films of silica and latex particles. However, since both films sh...
