  1. 21. Antimicrobial Polymer Composites for Medical Applications

    Författare :Peter Kaali; Sigbritt Karlsson; Ferruccio Doghieri; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; medical polymers; antimicrobial; body fluids; degradation; Polymer chemistry; Polymerkemi;

    Sammanfattning : The current study and discuss the long-term properties of biomedical polymers in vitro and invivo and presents means to design and manufacture antimicrobial composites. Antimicrobialcomposites with reduced tendency for biofilm formation should lead to lower risk for medicaldevice associated infection. LÄS MER

  3. 22. Interactions between Fe and organic matter and their impact on As(V) and P(V)

    Författare :Anneli Sundman; Per Persson; Thomas Borch; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; XAS; Fe III ; As V ; P V ; natural organic matter; Fe II; III -NOM complexes; Krycklan catchment; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Iron (Fe) speciation is important for many biogeochemical processes. The high abundance and limited solubility of Fe(III) are responsible for the widespread occurrence of Fe(III) minerals in the environment. LÄS MER

  4. 23. Coagulation of Cellulose: from Ionic-Liquid Solution to Cellulose Nanostructure

    Författare :Artur Hedlund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Wet Spinning; Cellulose; Ionic Liquids; Diffusion; Coagulation; Nonsolvent;

    Sammanfattning : Abstract A linear chain of glucose monomers, cellulose, provides the structural reinforcement of the cell walls of plants and constitutes almost half of their dry mass. Wood and other plant-based raw materials are processed on a large industrial scale to isolate the cellulose, which is then dissolved. LÄS MER

  5. 24. Eutectic Modification of Al-Si casting alloys

    Författare :Jenifer Barrirero; Frank Mücklich; Magnus Odén; Franz Jospeh Feikus; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Aluminum alloys with silicon as the major alloying element are the most widely used aluminum casting alloys. The eutectic phase in these alloys is formed by hard and brittle silicon plates in an aluminum matrix. Such silicon plates can act as crack propagation paths deteriorating the toughness of the material. LÄS MER

  7. 25. Design and Characterisation of new Anode Materials for Lithium-Ion Batteries

    Författare :Linda Fransson; Anthony West; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; in situ X-ray diffraction; graphite; Li-ion battery; anode materials; intermetallics; structure-property relationships; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Reliable ways of storing energy are crucial to support our modern way of life; lithium-ion batteries provide an attractive solution. The constant demand for higher energy density, thinner, lighter and even more mechanically flexible batteries has motivated research into new battery materials. Some of these will be explored in this thesis. LÄS MER
