  1. 1. Interactions between Wood Polymers in Wood Cell Walls and Cellulose/Hemicellulose Biocomposites

    Author : Jasna Stevanic Srndovic; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic FTIR spectroscopy; viscoelasticity; orientation; Norway spruce; protein; glucomannan; xyloglucan; polymer interactions; pectin; imaging FTIR microscopy; primary cell wall; nanocomposite films; dynamic 2D FTIR spectroscopy; xylan; wood fibre; cellulose; secondary cell wall; DMA; lignin;

    Abstract : A wood fibre is a complex multi component biocomposite that is hierarchically organised. The arrangement of a wood fibre on the ultrastructural level is highlycontrolled by the interactions between the main structural polymers, i.e. cellulose, various hemicelluloses and lignin, as well as in some parts also pectin and protein.

    Abstract : Popular Abstract in Swedish I atmosfären finns förutom olika gaser, såsom kväve, syre, vattenånga och en mängd gaser i låga koncentrationer, även partiklar. Dessa partiklar kallas aerosolpartiklar och de kan hålla sig svävande upp till flera veckor innan de deponeras till marken igen. READ MORE

  3. 3. No Hypervisor Is an Island System-wide Isolation Guarantees for Low Level Code

    Abstract : Popular Abstract in Swedish Den här avhandlingen beskriver olika experimentella metoder att framställa nanopartiklar med kontroll över storlek och sammansättning. En nanopartikel är en partikel som är mindre än 100 nanometer (1 nm är en miljondels millimeter). Utmaningen ligger i att partiklarna är såpass små. READ MORE
