  1. 21. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    Författare :Diana Bernin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diffusion; gel; alginate; pulsed field gradient NMR; 19F NMR; cellulose; 1H NMR; dendrimer; biomaterial; mass transport;

    Sammanfattning : Soft biomaterials, such as gels, play an important role in different kinds of products and applications, in particular in drug delivery systems, health care products, and food. Polymer gel's great ability to control mass transport is applied on e.g. the uptake of liquids in diapers. LÄS MER

  3. 22. Cellulose nanofibril materials with controlled structure : the influence of colloidal interactions

    Författare :Andreas Fall; Lars Wågberg; Anna Finne Wistrand; Paul Gatenholm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colloidal stability; cellulose nanofibrils; nanofibers; nanostructured materials; biocomposite; DLVO; gel;

    Sammanfattning : Nanoparticles are very interesting components. Due to their very large specific surface area they possess properties in between molecules and macroscopic materials. In addition, a material built up of hierarchically assembled nanoparticles could obtain unique properties, not possessed by the nanoparticles themself. LÄS MER

  4. 23. Shapeable cellulosic materials

    Författare :Malin Brodin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; composite; polyethylene; coagulation; material properties; cellulose ester; interactions; gel; cellulose; ionic liquid;

    Sammanfattning : ABSTRACTA palette of materials has been developed by the oil and gas sector. The expected depletion of fossil resources and the stress on the climate from burning them has, however, turned the world’s attention to renewable resources. LÄS MER

    Sammanfattning : Background Coagulase-negative staphylococci (CoNS) and in particular Staphylococcus epidermidis have emerged as major pathogens primarily causing nosocomial infections in patients with indwelling medical devices. These infections are often caused by multidrug-resistant strains of S. epidermidis (MDRSE). LÄS MER
