  4. 7. Oxidized Cladophora nanocellulose derivatives : Functionalization towards biocompatible materials

    Author : Igor Rocha; Jonas Lindh; Natalia Ferraz; Albert Mihranyan; Maria Strömme; Eva Malmström Jonsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cladophora nanocellulose; TEMPO oxidation; periodate oxidation; sulfonation; cellulose beads; surface properties; biomaterials; cell studies; hemocompatibility;

    Abstract : Nanocellulose is a promising candidate for biomedical applications because of its enhanced mechanical properties, increased surface area and greater porosity compared to bulk cellulose.This thesis investigates the functionalization of Cladophora nanocellulose and evaluates the influence of these modifications on physicochemical properties and biocompatibility of the material.

  5. 8. Foaming of Some Cellulose Derivatives - Initial Studies

    Author : Kristina Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological characterisation; Foaming; hydroxypropyl methylcellulose HPMC ; scale-up production; ethyl hydroxyethyl cellulose EHEC ; hot-mould baking; cellulose derivatives; extrusion;

    Abstract : Fossil-based polymeric foams, based on polymers such as polystyrene and polyurethane, are important and widely employed materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. There are however a few disadvantages with these foamed products. READ MORE

  6. 9. Foaming of cellulose derivatives and hemicellulose-containing materials

    Author : Kristina Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; β-glucan; arabinoxylan; scale-up production; hydroxypropyl methylcellulose HPMC ; ethyl hydroxyethyl cellulose EHEC ; hot-mould foaming; extensional viscosity; extrusion; hemicellulose; rheological characterisation; Foaming; xylan; cellulose derivatives;

    Abstract : Fossil-based polymeric foams are important materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. They are widely used in cushioning, absorbing and insulation applications. There are however a few disadvantages with these foamed products. READ MORE
