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

    University dissertation from Stockholm : Stockholm University

    Author : Elisabeth Hallgren; Stockholms universitet.; [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

    Abstract : This work concerns the interrelationship between thermodynamic, kinetic and structural aspects of crystal polymorphism. It is both experimental and theoretical, and limited with respect to compounds to substituted monocyclic aromatics. READ MORE

  3. 3. Rosetta spacecraft potential and activity evolution of comet 67P

    University dissertation from Uppsala : Uppsala universitet

    Author : Elias Odelstad; Uppsala universitet.; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rosetta; comet; 67P; RPC-LAP; RPC-MIP; Langmuir probe; spacecraft potential; plasma; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : The plasma environment of an active comet provides a unique setting for plasma physics research. The complex interaction of newly created cometary ions with the flowing plasma of the solar wind gives rise to a plethora of plasma physics phenomena, that can be studied over a large range of activity levels as the distance to the sun, and hence the influx of solar energy, varies.

  4. 4. Development and Implementation of Methods in Theoretical Chemistry

    University dissertation from Theoretical Chemistry, Lund University

    Author : Jesper Wisborg Krogh; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UO2; Electrostatic potential; Photo dissociation; Nuclear Quadrupole Moment; Relativity; RASSCF; LoProp; Method development; Parallelization; Sn; Bromoiodomethane; Theoretical chemistry; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : The method development research in the field of theoretical chemistry is the never ending quest for methods that are faster, gives more accurate results, and expands the possibilities. The work in this thesis is no exception to that statement. READ MORE

  5. 5. 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; Stockholms universitet.; [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
