  1. 6. Bilayers with Surfactant-induced Pores and Demixing in Micelles Studies of Segregation in Amphiphile Systems

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mari Kadi; Uppsala universitet.; [2003]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; fluorocarbon surfactants; amphiphile mixtures; perforated bilayers; segregation; NMR; surfactant selective electrode; cryo-TEM; SANS; AFM; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Sammanfattning : The focus of this thesis has been on the effects of segregation in mixtures of amphiphilic molecules. Two different systems were investigated: fluorocarbon-hydrocarbon surfactant mixtures and lipid-surfactant mixtures. LÄS MER

  2. 7. Formulation and characterization of W/O nano-dispersions for bioactive delivery applications

    Detta är en avhandling från Örebro : Örebro university

    Författare :Maria D. Chatzidaki; Örebro universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nano-dispersions; encapsulation; food; DLS; EPR; Cryo-TEM; SAXS; pH-stat; digestion; antioxidants; gastric lipase; pancreatic lipase; Kemi; Chemistry;

    Sammanfattning : The main objective of this study was the formulation of food-grade water-in-oil (W/O) nano-dispersions based mainly on medium or long-chain triglycerides. Two types of dispersions were formulated and structurally compared, namely emulsions and microemulsions. LÄS MER

  3. 8. Development and application of advanced electron microscopy techniques for materials in biological systems

    Detta är en avhandling från Örebro : Örebro university

    Författare :Pernilla Nevsten; Lunds universitet.; Lund University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; multiple-unit drug; EFTEM; EELS; cyanine dye; SSAT; cryo-TEM; virus; TEM; apoptosis; SEM; AFm; α-TCP; apatite; XEDS; TEM grid; microscopy supports;

    Sammanfattning : Theoretically, electron microscopy and scanning probe microscopy offer information on a scale beyond the optical microscope. However, the quality of the micrograph and the obtained information is limited by the sample preparation. LÄS MER

  4. 9. Association of Amphiphiles and Polyelectrolytes with DNA

    Detta är en avhandling från Physical Chemistry 1, Lund University

    Författare :Yulia S Mel'nikova; Lunds universitet.; Lund University.; [2000]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; cryo-TEM; SAXS; fluorescence microscopy; DNA condensation; DNA-polyelectrolyte; DNA- amphiphile interactions; Fysikalisk kemi;

    Sammanfattning : DNA- cationic amphiphile and DNA-cationic polymer systems were studied with respect to the intermolecular interactions, as well as structure and stability of formed complexes. The thesis is divided in two parts: one section is a summary and the other section contains five papers. LÄS MER

  5. 10. On the Physical Chemistry of Kraft Lignin – Fundamentals and Applications

    Detta är en avhandling från Magnus Norgren, Mid Sweden University, SE-851 70 Sundsvall, Sweden

    Författare :Magnus Norgren; Mittuniversitetet.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi; kraft lignin; sodium taurodeoxycholate; bile acid salts; stabilisa-tion; Hofmeister series; fractals; DLCA; RLCA; self-aggregation; colloid; self-diffusion coefficients; DLVO; Poisson-Boltzmann; pKa; dissociation; macromolecule; kraft cooking; lignin; Fysikalisk kemi; Physical chemistry; cryo-TEM; light scattering; 1H PFG NMR;

    Sammanfattning : This thesis describes the physical chemistry of softwood kraft lignin in aqueous alkaline solutions. Both fundamental and applicational aspects are discussed. Kraft lignin originates either from pulp fibres or from black liquor produced by kraft cooking. LÄS MER
