  2. 1. Lecithin-Based Microemulsions for Pharmaceutical use - Phase behavior and Solution Structure

    Author : Christian von Corswant; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; felodipine; solubilization; drug delivery; self-diffusion NMR; alkylmaltoside; microstructure; isopropyl myristate; triglyceride; soybean phosphatidylcholine; Microemulsion; lecithin; Livsmedelsteknik;

    Abstract : Microemulsions are thermodynamically stable, transparent solutions of water, oil and amphiphile(s). It is possible to incorporate large amounts of oil in microemulsions, which makes them interesting for use as a drug delivery vehicle for water insoluble drugs. A prerequisite for pharmaceutical use, however, is a low toxicity of the composition. READ MORE

  4. 2. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties

    Author : Joakim Balogh; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Light Scattering; NMR relaxation NMR self-diffusion; SANS contrast variation and contrast matched studies; saddle play modulus; made by C12E5; Nonionic microemulsion; balanced microemulsion; Fysikalisk kemi;

    Abstract : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. READ MORE

  5. 3. NMR Diffusion Studies of Association in Surfactant Systems Inclusion Complexes, Micellar Solutions and Microemulsions

    Author : Markus Nilsson; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; host-guest complexation; gemini surfactant; cyclodextrin; bolaform surfactant; self-diffusion NMR; pluronic; bicontinuous microemulsion; polydispersity; boosting effect;

    Abstract : The aim of this thesis has been to investigate self-diffusion behavior of host-guest complex, microemulsion and polymer solution. Pulsed Field Gradient NMR (PFG-NMR) was shown to provide detailed molecular information in all system studied. READ MORE

  6. 4. NMR Self-Diffusion Studies and Stability Studies of Emulsions

    Author : Ingrid Lönnqvist; LTH Ingenjörshögskolan vid Campus Helsingborg; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coalescence; emulsion stability; size distribution; restricted diffusion; self-diffusion coefficient; self-diffusion PGSE NMR; surfactant; emulsifier; continuous phase; microemulsion; phase diagram; emulsion; multiple emulsion; cream; conductivity; Physics; Fysik; Chemistry; Kemi;

    Abstract : The aim of this study is to characterize emulsion systems by self-diffusion PGSE NMR methods. The specifics of the emulsions studied are all taken from the literature and they are of the W/O or O/W type stabilized with different emulsifiers. READ MORE

  7. 5. Phase Diagrams, Microstructure and Phase Separation in Alkyl Glucoside Systems

    Author : Johan Reimer; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Physical chemistry; micellar network; NMR diffusometry; microemulsion; microstructure; phase diagram; phase separation; phase behaviour; alkyl glucoside; sugar surfactant;

    Abstract : The aim of this thesis work was to study phase diagrams, microstructure and phase separation in alkylglucoside systems. Both alkyl glucoside/water systems and microemulsions with alkyl glucosides have been studied. READ MORE
