  2. 41. Pulsed Field Gradient NMR Studies of Diffusion in Polymer Gels

    Author : Diana Bernin; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 43. Engineering and Functionalization of Hemicellulose Hydrogels

    Author : Weifeng Zhao; Karin Odelius; Ann-Christine Albertsson; Ulrica Edlund; Tina Vermonden; KTH; []
    Keywords : Hemicellulose; O-acetyl-galactoglucomannan; hydrogels; stimuli-responsive; aniline tetramer; aniline pentamer; electro-active; conductivity; pH-sensitivity; magnetic field-responsive; micro-gels; swelling; drug delivery.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Hemicellulose is the second most abundant component in wood and is an important renewable resource  that is used in films, paper composites and biofuels.  Hemicelluloses  have  several  advantages,  including  their abundance,  degradability  and  renewability. READ MORE

  6. 44. On the Modelling of Mechanical Dewatering in Papermaking

    Author : Vinicius Lobosco; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paper; modelling; dewatering; forming; wet pressing; fibre network stress; rheology; hysteresis; intra-fibre water; compressibility; structural stress; stress-strain; restricted gels; swelling;

    Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

  7. 45. Microstructure and liquid mass transport control in nanocomposite materials

    Author : Christoffer Abrahamsson; Chalmers tekniska högskola; []
