  1. 1. On the Extraction of Essential Oils by Supercritical Carbon Dioxide and its Influence on the Mesomorphic Phase Structures

    Author : José da Cruz Francisco; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Natural oils; fats and waxes technology; Naturliga oljor; fetter; vax; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; phase behavior; soybean lecithin; monoolein; cineole; terpenes; eucalyptus; extraction; Essential oils; supercritical carbon dioxide;

    Abstract : A comparison of essential oils from leaves of Eucalyptus camaldulensis Dehn. obtained by hydrodistillation (HD) and supercritical carbon dioxide (SC-CO2) extraction is presented. Selected major components of the oils showed a predominance of higher molecular weight components in the SC-CO2 extracts than in those obtained by HD. READ MORE

  2. 2. Electrochemical investigations on lipid cubic phases

    Author : Mohammad Yaser Khani Meynaq; Britta Lindholm-Sethson; Solomon Tesfalidet; Ehud M. Landau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monoolein; Electrochemical Impedance Spectroscopy; lipid cubic phase; ionic interaction; biofuel cell; fysikalisk kemi; Physical Chemistry;

    Abstract : 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. READ MORE

  3. 3. ALA and m-ALA in bicontinuous lipid formulations: -Characterization and Transdermal Delivery

    Author : Johanna Bender; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; passive diffusion; SAXS; monoolein; methyl 5-aminolevulinate hydrochloride; NMRD; sponge phase; 5-aminolevulinic acid hydrochloride; iontophoresis;

    Abstract : δ-Aminolevulinic acid (ALA) and its methyl ester (m-ALA) are both used in photodynamic therapy (PDT) of certain non melanoma skin cancers as the basal cell carcinoma (BCC). In PDT the cancer cells are destroyed by a photochemical reaction that occurs when a photosensitive molecule is irradiated with light of a certain wavelength. READ MORE

  4. 4. PEG and lipids in solid dispersions and liquid crystals - structure and phase behaviour

    Author : Johan Unga; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bicontinuous sponge phase; polyethylene glycol; monoolein; bicontinuous cubic phase; lipids; differential scanning calorimetry; phytantriol; small angle X-ray diffraction; solid dispersions;

    Abstract : In this thesis, two different kinds of nano-structured systems have been studied; solid dispersion systems of polyethylene glycol (PEG) and liquid crystalline systems containing the polar lipids monoolein (MO) and phytantriol (PT). Solid dispersions of PEG were studied with addition of different substances, lipids or parabens. READ MORE

  5. 5. Lipid Self-Assembly and Lipase Action

    Author : Johanna Borné; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; specific activity.; Physical chemistry; Fysikalisk kemi; vesicles; cubosomes; liquid crystalline phases; sodium oleate; oleic acid; diolein; monoolein; Oleic acid based acyl glycerols; Thermomyces lanuginosa lipase;

    Abstract : In this thesis the action of the Thermomyces lanuginosa lipase (TLL) on "real" substrates, that is, lipid aggregates - vesicles, micelles, emulsions, gels and liquid crystals is discussed. Even for a pure triolein, the system becomes quite complex as the lipolytic process starts, both in terms of structure and composition, involving 5 additional components - diolein (DO), monoolein (MO), oleic acid (OA), sodium oleate (NaO) and glycerol .
