  2. 1. Electrostatic interaction chromatography : aspects of the salt dependent interactions of proteins

    Author : Elisabeth Hallgren; Klaus Unger; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Analytical Chemistry; analytisk kemi;

    Abstract : This thesis studies the ionic strength dependence of protein retention in ion-exchange chromatography (IEC). It discusses some aspects of the use and applicability of retention models in describing the interaction between a protein and the highly charged stationary phase. READ MORE

  4. 2. Electrostatic Interactions in Coarse-Grained Simulations : Implementations and Applications

    Abstract : Electrostatic interactions in bio-molecular systems are important not only in the living cell but also in more technical applications. Using molecular simulation as well as approximate theories the properties of a number of aqueous protein solutions have been studied. READ MORE

  6. 4. Modelling anisotropic interactions in colloidal systems

    Author : Alexei Abrikossov; Fysikalisk kemi; []
    Keywords : SIMULATION; Modelling; electrostatic interactions; Colloids; Statistical mechanics; SIMULATION; Modelling; electrostatic interactions; colloid; Statistical mechanics;

    Abstract : There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. READ MORE
