  2. 1. Bio-inspired cellulose nanocomposites and foams based on starch matrix

    Author : Anna Svagan; Lars A. Berglund; Salvatore Iannace; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; starch; cellulose nanofibers; foam; nanocomposites; cushioning materials; biodegradable; expanded polystyrene; mechanical properties; diffusion; Polymer chemistry; Polymerkemi;

    Abstract : In 2007 the production of expanded polystyrene (EPS) in the world was over 4 million tonnes and is expected to grow at 6 percent per year. With the increased concern about environmental protection, alternative biodegradable materials from renewable resources are of interest. READ MORE

  4. 2. Bio-inspired polysaccharide nanocomposites and foams

    Author : Anna Svagan; Lars Berglund; Mats Stading; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cellulose; starch; microfibrillated cellulose; biomimetic; nanocomposite; nanocomposite foam; mechanical properties; Biomaterials; Biomaterial;

    Abstract : Today, the majority of materials used for single-use packaging are petroleum-based synthetic polymers. With increased concern about the environmental protection, efforts have been made to develop alternative biodegradable materials from renewable resources. Starch offers an attractive alternative since it is of low cost and abundant. READ MORE

  5. 3. Perfluorocarbon microdroplets stabilized by cellulose nanofibers : Toward ultrasound-mediated diagnostics and therapy

    Author : Ksenia Loskutova; Dmitry Grishenkov; Anna Justina Svagan; Gaio Paradossi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrasound; acoustic droplet vaporization; phase-change contrast agent; Pickering emulsion; cellulose nanofiber; Ultraljud; akustisk droppförångning; kontrastmedel med fasförändring; Pickeringemulsion; cellulosananofiber; Teknik och hälsa; Technology and Health;

    Abstract : Ultrasound contrast agents consist of gas-filled micrometer-sized bubbles that are injectedinto the blood stream. Ultrasound contrast agents are an invaluable tool for ultrasound imaging of the cardiac muscle and highly vascularized structures such as kidneys and the liver. READ MORE

  6. 4. Plant cell-inspiredmicrocontainers: Fabrication, Characterization and Applications

    Author : Thomas Paulraj; Anna Justina Svagan; Daniel Crespy; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Biomimetic materials have been inspiring mankind since a longtime for applications in a variety of fields. In particular, the production of lipidbasedvesicles have aided in our understanding of a variety of functions in animalcells, and also served as e.g. drug delivery systems and bioreactors. READ MORE

  7. 5. Biobased and biodegradable binders for paper and nonwoven

    Author : Maria Wennman; Mikael S. Hedenqvist; Anna Justina Svagan; Mårten Hellberg; Wim Thielemans; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Polyelectrolyte complex; binder; chitosan; carboxymethyl cellulose; citric acid; nonwoven; tensile strength; hydrophobicity; Polyelektrolytkomplex; bindemedel; kitosan; karboximetylcellulosa; citronsyra; nonwoven; dragstyrka; hydrofobicitet; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nonwovens are textile-like materials with similarities close to paper. One significant sector where nonwovens are used is for single-use products such as wet wipes and hygiene products. With an increasing global population, the manufacturing and use of nonwovens have grown significantly. READ MORE
