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

    University dissertation from Stockholm : Stockholm University

    Author : Elisabeth Hallgren; Klaus Unger; [1999]
    Keywords : 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. 4. A structural study into the boundary surface and associated curvature of three-dimensional mesoporous silica crystals

    University dissertation from Stockholm : Institutionen för fysikalisk kemi, oorganisk kemi och strukturkemi

    Author : Keiichi Miyasaka; Osamu Terasaki; Reinhard Nesper; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mesoporous crystal; electron crystallography; electrostatic potential map; equi-potential surface; curvature; multiplly-twinned particle; MEDICINE Chemistry; MEDICIN Kemi; Structural Chemistry; strukturkemi;

    Abstract : Since their first discovery in the early 1990s, mesoporous crystals (MCs) have fascinated researchers in various fields because of their interesting structures and their potential uses. Electron crystallography (EC) gives the direct three-dimensional (3D) realization of a crystal as a reconstructed electrostatic potential map (EPM). READ MORE

  5. 5. Interaction Between Microgels and Oppositely Charged Peptides

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helena Bysell; Martin Malmsten; Per Hansson; Walter Richtering; [2009]
