“…Although soft matter is not solid, the crack and rupture problems in this materials are very important and have been intensively studied [71][72][73][74][75][76][77][78][79][80][81]. It is different from the topological defects---dislocations, the crack is a kind of metric defects, which presents important application tool.…”

This article provides a detailed review on the generalized dynamics of soft-matter quasicrystals developed recent years. Comparing to solid quasicrystals consisted mainly with metallic alloys, soft-matter quasicrystals have been observed in liquid crystals, polymers, colloids, nanoparticles and surfactants, which indicates quite different formation mechanism. Based onLandau-Anderson theory and group representation theory, we have studied the symmetry, symmetry breaking and elementary excitations for the observed and possible soft-matter quasicrystals. We further proposed one more elementary excitation -fluid phonon additional to the phonon and phason for solid quasicrystals, to quantitatively describe the dynamics of soft-matter quasicrystals. The general governing equations and the solutions of the dynamics evolution on the distribution, deformation and motion of the new phase are studied, which reveal quite distinguishing dynamic behaviour with those of conventional fluids and solid quasicrystals. Someapplications are introduced, which show this is an important field of new materials and materials science. 9

“…Stable dispersions of colloidal polymer particles in water, known as synthetic latex, are dried to create the binder in waterborne paints. 1,2 Colloidal polymer particles (often in mixtures) are also the primary component in waterborne pressure-sensitive adhesives, 3 sun screen, 4 inks, 5 binders for the active ingredients in agricultural treatments for crops, [6][7][8] and coatings for drug encapsulation and controlled release. 9,10 Solid colloidal films are typically made by spreading a dispersion or suspension in liquid on a solid substrate and allowing the continuous liquid phase to evaporate.…”

A critical and quantitative review of the stratification of particles during the drying of colloidal films

For a wide range of applications, films are deposited from colloidal particles suspended in a volatile liquid. There is burgeoning interest in stratifying colloidal particles into separate layers within the final dry film to impart properties at the surface different to the interior. Here, we outline the mechanisms by which colloidal mixtures can stratify during the drying process. The problem is considered here as a three-way competition between evaporation of the continuous liquid, sedimentation of particles, and their Brownian diffusion. In particle mixtures, the sedimentation of larger or denser particles offers one means of stratification. When the rate of evaporation is fast relative to diffusion, binary mixtures of large and small particles can stratify with small particles on the top, according to physical models and computer simulations. We compare experimental results found in the scientific literature to the predictions of several recent models in a quantitative way. Although there is not perfect agreement between them, some general trends emerge in the experiments, simulations and models. The stratification of small particles on the top of a film is favoured when the colloidal suspension is dilute but when both the concentration of the small particles and the solvent evaporation rate are sufficiently high. A higher particle size ratio also favours stratification by size. This review points to ways that microstructures can be designed and controlled in colloidal materials to achieve desired properties.

“…Regardless of top-down or bottom-up approaches, photonic crystals with specific optical properties are designed by the unit of structure, unlike atoms or molecules. The patterning of particles larger than atoms or molecules are now one of the popular techniques to fabricate new materials in general, and they are often referred to as ‘metamaterials’, where the self-assembly of particles from drying suspension often plays an important role [7–10]. Thus, drying of particle dispersion is widely exploited in scientific research and industry.…”
