  1. 1. Electrochemical investigations on lipid cubic phases

    Detta är en avhandling från Umeå : Umeå University

    Författare :Mohammad Yaser Khani Meynaq; Umeå universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : Electrochemical Impedance Spectroscopy (EIS) was used to develop a novel methodology for studying ionic interaction with lipids arranged in a lipid cubic phase (LCP). Studying different types of ions, both cations and anions, validated the method. LÄS MER

  3. 3. On the crystallization of membrane proteins in lipidic sponge and cubic phases

    Detta är en avhandling från Umeå : Umeå University

    Författare :Pia Jeanette Hindrichsen; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; monoolein MO ; selachyl alcohol; cubic phase; sponge phase; small angle X-ray scattering; protein crystallization; phytantriol PT ;

    Sammanfattning : Membrane proteins are involved in many important biological processes and in order to understand their mechanism, their three-dimensional structures need to be elucidated to high resolution by for example X-ray crystallography. However, there is only limited structural knowledge for membrane proteins which is partly explained by the difficulties in obtaining well-diffracting crystals. LÄS MER

  4. 4. FACING THE CHALLENGE OF SKIN PENETRATION - A STUDY ON LIPIDIC LIQUID CRYSTALLINE PHASES FOR DERMAL DRUG DELIVERY

    Detta är en avhandling från Umeå : Umeå University

    Författare :Hanne Evenbratt; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; 5-diol; liquid crystalline phases; N-Methyl-2-pyrrolidone; pentane-1; glyceryl monooleat; propylene glycol; dermal drug delivery; glyceryl monooleyl ether; cubic phase; reversed hexagonal phase;

    Sammanfattning : The skin is a barrier which protects us against daily attacks of foreign substances. From a pharmaceutical perspective it is also an interesting delivery route with its large surface and possibility to reach the blood stream circumventing first passage metabolism. With the varied size, structure etc. LÄS MER

  5. 5. Amphiphilic Molecules in Aqueous Solution

    Detta är en avhandling från Umeå : Umeå University

    Författare :Gerd Persson; Umeå universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

    Sammanfattning : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.
