  4. 3. Understanding overlooked molecular interactions in the cellulose/NaOH(aq) system

    Författare :Maria Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; ATR-IR; dissolution; cellulose; NMR; urea; CO2; NaOH aq ;

    Sammanfattning : The cold NaOH(aq) system is a promising process for the production of textile fibres. Although the process has been studied for almost a century, there remain unsolved research issues, especially regarding the dissolution mechanism. LÄS MER

  5. 4. Nuclear magnetic resonance studies of water self-diffusion in porous systems

    Författare :Daniel Topgaard; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion diffraction; nonfreezing; anisotropy; tortuosity; cross relaxation; emulsion; starch; cellulose; porous material; water; NMR; self-diffusion; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Proton nuclear magnetic resonance (NMR) was used to study the self-diffusion of water in porous systems that respond to a change in water content in order to elucidate the porous structure and the properties of the confined water. In the carbohydrate systems cellulose fibers and starch granules, water is free to move throughout the porous objects, albeit with a rate reduced from the value of the bulk liquid, The reduction is related to the tortuosity of the pore space filled by water.
