  2. 21. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks

    Author : Anna Finne; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ring-opening polymerization; coordination-insertion; germanium; cyclic tin alkoxides; spirocyclic initiators; poly L-lactide ; poly 1; 5-dioxepan-2-one ; triblock; star-shaped; network; functionalization; morphology; AFM; Polymer chemistry; Polymerkemi;

    Abstract : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. READ MORE

  4. 22. Electronic Properties of Metal Oxide Films Studied by Core Level Spectroscopy

    Author : Jan Hinnerk Richter; Anders Sandell; Håkan Rensmo; Anne Borg; Uppsala universitet; []
    Keywords : Physics; electron spectroscopy; metal oxide; chemical vapour deposition; ion insertion; metal organic; band alignment; zirconium; titanium; silicon; high k; Fysik;

    Abstract : In this dissertation core level electron spectroscopy has been employed to study various aspects of metal oxide films grown under ultra-high vacuum conditions. Studies on in situ ion insertion of lithium into thin TiO2 systems were performed. READ MORE

  5. 23. Insertion and Topology of Inner Membrane Proteins in Escherichia coli

    Author : Annika Sääf; Tony Pugsley; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Abstract : Integral membrane proteins are found in all cellular membranes and fulfil many of the functions that are central to life. They maintain the membrane structure, but are also involved in the regulation of different cellular processes. READ MORE

  6. 24. Identification of novel antibiotic resistance genes through the exploration of mobile genetic elements

    Author : Mohammad Razavi; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Environment; Metagenomics; Antibiotic resistance; Mobile genetic elements; Insertion sequences; Integron; Resistome; Next-generation sequencing;

    Abstract : Backgrounds and aims: The evolution of multi-resistant pathogens is seriously threatening our ability to provide modern healthcare. Many of the mobile resistance factors in clinics appear to originate from environmental bacteria. READ MORE

  7. 25. Aspects of oral implant technology and osseointegration

    Author : Rainde Naiara Rezende de Jesus; Malmö universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; oral implants; surface topography; surface roughness; surface energy; surface wettability; hydrophilicity; macrogeometry; implant body; thread design; surgical protocol; oversized drilling; osseointegration; bone-to-implant contact; bone density; primary implant stability; insertion torque; removal torque; removal energy; connection stiffness; osteoclasts; RAW264.7 cells; gene expression;

    Abstract : Behandling med käkbensförankrade tandimplantat är en vanlig metod för att ersätta förlorade tänder hos helt och partiellt tandlösa patienter. Trots att implantatbehandling uppvisar en långsiktigt hög lyckande- och överlevnadsfrekvens (90–95% efter 10 år) så förekommer implantatförluster och marginal benförlust kring implantaten under det första året efter insättning och/eller belastning, vilket kan försämra det estetiska resultatet.
