Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Substrate Stress Relaxation Regulates Cell‐Mediated Assembly of Extracellular Matrix
Advanced Functional Materials, EarlyView.Silicone‐based viscoelastic substrates with tunable stress relaxation reveal how matrix mechanics regulates cellular mechanosensing and cell‐mediated matrix remodelling in the stiff regime. High stress relaxation promotes assembly of fibronectin fibril‐like structures, increased nuclear localization of YAP and formation of β1 integrin‐enriched ...

Physical Review B, 1994
We examine the possibility of quasicrystalline metastable states for one- and two-component hard-sphere solids, systems whose excess free energies are entirely entropic. The investigations are carried out using the self-consistent modified weighted density approximation of density functional theory as applied to inhomogeneous systems.

Journal of Colloid and Interface Science, 2008
We demonstrate an extension of a UV-Vis spectroscopy method to determine the phase boundaries for thermosensitive colloids as an alternative to the time-consuming sedimentation method. The Bragg attenuation peak from colloidal crystallites was monitored during the quasi-equilibrium colloidal crystal melting.

Hard-sphere mixtures near a hard wall
The Journal of Chemical Physics, 1989We report a study of hard-sphere mixtures of different sizes near a hard wall using both the Monte Carlo method and density functional theory. The theory is based on a semiempirical free-energy functional for an inhomogeneous hard-sphere mixture and is similar to that developed by Tarazona for pure hard-sphere fluids. Comparison between the theoretical

Dynamics of hard-sphere suspensions
Physical Review E, 1994A systematic theory for the dynamics of concentrated hard-sphere suspensions of interacting Brownian particles with both hydrodynamic and direct interactions is presented. An alternative equation for the number density of particles is derived. The volume-fraction dependence of the short- and long-time self-diffusion coefficients is thus explored from a

Physica, 1971
Abstract The Kirkwood-Salsburg system of integral equations is used for the calculation of the distribution functions of a hard-sphere gas. Different approximations are established according to the degree of interactions of the covering spheres. The first-approximation integral equation is rigorously solved following a method given by Wertheim, from ...

Diffusion in hard sphere suspensions
Physica A: Statistical Mechanics and its Applications, 1983Abstract We study the wavenumber-dependent long-time collective and self-diffusion coefficients of a suspension of hard spheres with neglect of hydrodynamic interactions. At low density we obtain exact analytic results. At high density we employ the two-body diffusion approximation described in an earlier article. The collective diffusion coefficient
