  1. 1. Ternary Block Copolymer Systems - Phase Behaviour and Phase Structure

    University dissertation from Birgitta Svensson, Physical Chemistry 1, Lund University

    Author : Birgitta Svensson; Lunds universitet.; Lund University.; [1999]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lyotropic; Theoretical chemistry; thermotropic; SANS; SAXS; scattering; semicrystalline; reverse micelle; micellar solution; liquid crystalline; phase diagram; phase behaviour; block copolymer; pluronic; poly ethylene oxide ; poly propylene oxide ; quantum chemistry; Teoretisk kemi; kvantkemi;

    Abstract : Ternary isothermal (25°C) polyoxyalkylene triblock block copolymer ((EO)x(PO)y(EO)x where x is the number of ethylene oxide, EO, segments and y is the number of propylene oxide, PO, segments) systems with water and p-xylene as selective solvents for the PEO and PPO blocks, respectively, were chosen as study systems in this thesis as these ternary systems are good model systems for the self-assembly of block copolymers. The phase behaviour has been studied at varied block copolymer molecular weight and relative PEO/PPO block ratio. READ MORE

  2. 2. Combinatorial Synthesis of Pilicides

    University dissertation from Anette Svensson, Organic Chemistry 2, Chemical Center, Lund University

    Author : Anette Svensson; Lunds universitet.; Lund University.; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorinated linkers; gel-phase 19F NMR spectroscopy; E. coli bacteria; pilicides; combinatorial chemistry; solid-phase synthesis; Organic chemistry; Organisk kemi;

    Abstract : This thesis describes a combinatorial approach to design and synthesis of three libraries of compounds, referred to as pilicides, designed to target periplasmic chaperones present in uropathogenic Escherichia coli bacteria that are the main cause of urinary tract infections. Periplasmic chaperones are required for assembly of adhesive organelles, i. READ MORE

  3. 3. Phase Equilibria and Structures of Oppositely Charged Polymers and Surfactants in Water

    University dissertation from Anna Svensson, Physical Chemistry 1, Center for Chemistry and Chemical Engineering, Lund University

    Author : Anna Svensson; Lunds universitet.; Lund University.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PFG NMR; self diffusion; hexagonal; cubic Pm3n; liquid crystals; SAXS; polymer; counterion; complex; polyelectrolyte; surfactant; Monte Carlo simulations; Physical chemistry; Fysikalisk kemi;

    Abstract : A new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. READ MORE

  4. 4. Dendritic cell interactions with Gram negative bacteria

    University dissertation from Mattias Svensson, Sölvegatan 19, 223 62 Lund

    Author : Mattias Svensson; Lunds universitet.; Lund University.; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virology; mycology; Major histocompatibility complex molecules; Dendritic cells; Gram negative bacteria; Antigen processing; Antigen presentation; bacteriology; Microbiology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : The interaction between murine bone marrow-derived dendritic cells (DC) and the Gram negative bacteria Salmonella typhimurium and Escherichia coli have been characterised. These studies showed that DC phagocytosed and processed S. typhimurium and E. READ MORE

  5. 5. Application of the SASW-technique in geotechnical in-situ testing

    University dissertation from Mats Svensson, Geotechnology, Box 118, 221 00 LUND

    Author : Mats Svensson; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogeologi; teknisk geologi; Spectral Analysis of Surface Waves; shear modulus; SASW; multichannel; inversion; Gmax; teknisk geografi; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; geographical and geological engineering; Hydrogeology; Civil engineering; hydraulic engineering; offshore technology; soil mechanics; Väg- och vattenbyggnadsteknik;

    Abstract : With the main aim to test the applicability of the surface wave seismic technique Spectral Analysis of Surface Waves (SASW), used for determination of the shear stiffness (shear modulus - Gmax), four areas of applications have been studied. The four areas have been sites with natural geological conditions, sites where non destructive testing is necessary, pavement testing and multichannel testing. READ MORE
