      abstract     = {This thesis comprises a theoretical description of the
                      microstructure, diffusion and rheological properties of
                      dispersions of charged Brownian particles. We have
                      developed, and thoroughly tested, various analytical
                      theoretical methods to calculate static and dynamic
                      properties, and have applied them to various experimental
                      systems. The common features of these analytic methods are
                      their high levels of accuracy, versatility, and numeric
                      efficiency. We have calculated a large variety of
                      equilibrium and short-time dynamic properties and also some
                      long-time properties, including static structure factors,
                      translational collective and self-diffusion coefficients,
                      hydrodynamic functions, and static and high-frequency shear
                      viscosities. Suspensions of synthetic silica spheres,
                      moderately aspheric bovine serum albumin proteins, and thin
                      gibbsite platelets have been examined in collaboration with
                      experimental groups in Jülich, Tübingen, Utrecht
                      (Netherlands) and Košice (Slovakia). (Dynamic) Light- and
                      X-ray scattering data, and shear viscosities for these
                      systems have been calculated for concentrations up to the
                      liquid-solid or liquid-liquid crystal phase transition
                      point, allowing for a detailed characterization of the
                      suspended particles. In comprehensive parameter studies, we
                      have validated our analytic methods of calculating
                      equilibrium pair-correlations and (short-time) dynamics
                      against numerous computer simulation results. The computer
                      simulations were conducted by Prof. Banchio (Uni. Córdoba,
                      Argentina), in the course of an extended collaboration. A
                      model of monodisperse, charged Brownian spheres, suspended
                      in a structureless fluid, and interacting via a screened
                      Coulomb potential, serves as the basis of our analytic
                      schemes. The salt content of the suspension affects the
                      range of electrostatic repulsion, which can cause pronounced
                      pair correlations in low-salinity systems at very low
                      colloid concentrations. An important advancement of this
                      thesis is the development of a new analytic integral
                      equation scheme, named Modified Penetrating Background
                      corrected Rescaled Mean Spherical Approximation, which
                      allows for fast and accurate calculation of static pair
                      correlations. The pair correlation functions computed by
                      this method serve as input for various analytic methods of
                      calculating diffusion properties, and static and
                      high-frequency shear viscosities of chargestabilized
                      suspensions. A severe complication in computing dynamic
                      properties arises from the necessary inclusion of
                      long-ranged, non-pairwise additive hydrodynamic
                      interactions. To this end, we provide [...]},
