      abstract     = {Thermophoresis or thermodiffusion has become an important
                      tool to monitor protein–ligand binding as it is very
                      sensitive to the nature of solute–water interactions.
                      However, the microscopic mechanisms underlying
                      thermodiffusion in protein systems are poorly understood at
                      this time. One reason is the difficulty to separate the
                      effects of the protein system of interest from the effects
                      of buffers that are added to stabilize the proteins. Due to
                      the buffers, typical protein solutions form multicomponent
                      mixtures with several kinds of salt. To achieve a more
                      fundamental understanding of thermodiffusion of proteins, it
                      is therefore necessary to investigate solutions of buffer
                      salts. For this work, the thermodiffusion of aqueous
                      potassium salt solutions has been studied systematically. We
                      use thermal diffusion forced Rayleigh scattering experiments
                      in a temperature range from 15 °C to 45 °C to investigate
                      the thermodiffusive properties of aqueous solutions of five
                      potassium salts: potassium chloride, potassium bromide,
                      potassium thiocyanate, potassium acetate, and potassium
                      carbonate in a molality range between 1 mol/kg and 5 mol/kg.
                      We compare the thermophoretic results with those obtained
                      for non-ionic solutes and discuss the thermophoresis of the
                      salts in the context of ion-specific solvation according to
