For instance, faster growth can be realized in polyelectrolyte solution with the help of shear flow [28]. The crystal fronts move very fast. Thus, the networks hindering movement of the crystal

• are less periodic than those of isotropic crystals, because the movement of 1D or 2D crystals during evaporation of the droplets is often hindered due to steric effects. Confined assembly helps to optimize the alignment of 1D or 2D crystals by introducing additional flow, that is, shear flow or

• magnetic field and a shear flow. Both influences are able to induce the ferrocholesteric–ferronematic transition independently; however, the differences between the magnetic field orientation and the flow alignment direction lead to a competition between magnetic and hydrodynamic mechanisms of influence on

• the ferrocholesteric structure. We analyze various orientations of a magnetic field relative to the direction of a shear flow. The pitch of the ferrocholesteric helix is obtained as function of the strength and the orientation angle of the magnetic field, the shear velocity gradient and a reactive

We find out that imposing a shear flow leads to a shift of the magnetic field threshold. The value of the critical

The CNT agglomerates are dispersed by shear flow created by twin screws rotating at high speed [35]. Abdalla et al. dispersed CNTs by extrusion into EPIKOTE resin EPON 815C (bisphenol A with n-butyl
