  1. 21. Measuring Material Properties through Gradient Based NMR: Diffusion and Imaging

    Författare :Ingrid Åslund; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intracellular diffusion; homogeneous length-scale; material properties; emulsions; yeast suspensions; lamellar phase; NMR; self-diffusion; membrane permeability and bending rigidity;

    Sammanfattning : In this work new methods based Nuclear Magnetic Resonance (NMR) have been developed to measure different kinds of structural properties in soft materials. The advantage of using NMR as a technique to measure material properties is that it is non-destructive, which makes it possible to measure on the actual piece of material that will be used for the application.

  3. 22. Enhancing material and biological properties of calcium phosphate bone substitute

    Författare :Christopher Camire; Lund Ortopedi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; materialteknik; Non-metallic mineral technology; Icke-metallisk mineralteknik; Biotechnology; Bioteknik; Materiallära; Material technology; Technological sciences; Teknik; Naturvetenskap; reumatologi; Surgery; orthopaedics; traumatology; Kirurgi; ortopedi; traumatologi; Natural science; muskelsystem; Skelett; muscle system; rheumatology locomotion; Bone Substitute; Calcium Phosphate; Skeleton; Medicin människa och djur ; Medicine human and vertebrates ; Osteoconductivity; Silicon; Mechanical Properties; Crystallinity; Reactivity; Calorimetry; Hydroxyapatite;

    Sammanfattning : Calcium phosphate materials (CaPs) have proven biocompatible and useful in clinical situations. One CaP showing promise in the clinic is alpha phase tricalcium phosphate ([alpha]-TCP). [alpha]-TCP in powder form can be hydrated and undergoes a reaction resulting in calcium deficient hydroxyapatite (CDHA). LÄS MER

  4. 23. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Författare :Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER

  5. 24. Freeze-Dried Wheat Gluten-Based Foams

    Författare :Thomas Blomfeldt; Mikael Hedenqvist; Delcour Jan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Wheat gluten; Glutenin; Gliadin; Renewable; Freeze-drying; Pore structure; Baceterial cellulose; Glycerol; Mechanical properties; Thermal conductivity; Combustion properties;

    Sammanfattning : This thesis presents wheat gluten foams as an alternative to the available commercialfoams. Polymeric foams, like all plastics, are mostly made from petroleum, and this isaffecting the environment negatively with the emission of greenhouse gases and generation oflandfills. LÄS MER

  7. 25. Bioactive nanocellulose materials for the treatment of chronic wounds

    Författare :Anna Blasi Romero; Natalia Ferraz; Daniel Aili; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; covalent immobilization; wound healing; antioxidant properties; antibacterial properties; anti-inflammatory properties; stimuli responsive hydrogels; reactive oxygen species; host defense peptides; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Chronic wounds represent a burden for the healthcare system and significantly affect the quality of life of the patients. There is currently a lack of efficient treatments but new, improved therapeutic approaches are under development. LÄS MER
