  2. 16. Structural design and properties of hydrogel biomaterials

    Author : Mikael Larsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyacrylic acid; Mechanical properties; Microfibrillated cellulose; Drug release; Chitosan; Biomaterials; Swelling; Hydrogels;

    Abstract : Today a range of materials are used in medical applications; such materials are collectively denoted as biomaterials. A special class of biomaterials currently given much scientific interest is hydrogels. In particular a contemporary research topic is to create multicomponent materials in which synergetic effects are achieved. READ MORE

  4. 17. Development of Novel In Situ Microscopy Techniques for the Study of Water Interaction with Soft Materials

    Author : Anna Jansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; environmental scanning electron microscopy; polymer film; manipulator; yeast cell; swelling; in situ; water transport; cellulose fibre; osmotic shock; water interaction;

    Abstract : The transport of water in soft materials can occur in liquid or gas phase and is highly dependent on the material microstructure and the structure dynamics. Understanding these relationships is the basis for the development of predictive models that can aid the design of new and improved functional materials. READ MORE

  5. 18. Multiphase continuum modeling of wood : A hybrid mixture theory approach

    Author : Winston Mmari; Björn Johannesson; Lynn Schreyer; Linnéuniversitetet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Moisture transport; Coupled heat and moisture; Over-hygroscopic; Hybrid mixture theory; Mixture theory; Swelling; Hygro-mechanical; Non-linear elasticity; Large deformation; Phase field crack model; Anisotropic cracking; FEM; Numerical model; Norway spruce; Wood; Porous media; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood has been used as a construction material for a very long time. The development of efficient industrial production processes of wood has expanded the use of the material with the introduction of new products, such as engineered wood products. READ MORE

  6. 19. Chemical Pathways for Galactoglucomannan-based Materials

    Author : Jens Voepel; Ann-Christine Albertsson; Ulrica Edlund; Søren Hvilsted; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polysaccharides; hemicelluloses; galactoglucomannan; renewable; chemical modification; hydrogels; swelling; crosslinking; release; SET-LRP; living polymerization; grafting; hybrid materials; Polymer chemistry; Polymerkemi;

    Abstract : Polysaccharides are an important resource for a variety of products, from food via fuel supply to functional materials of every kind. Due to their natural diversity they can be found in many special applications, e.g. in the biomedical sector and are the major renewable resource for materials of many kinds. READ MORE

  7. 20. Interactions between polymers and the environment

    Author : Nazanin Alipour; Mikael S. Hedenqvist; Antal Boldizar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deltamethrin; piperonyl butoxide; polyethylene; migration; multilayer film; EVOH; n-hexane; crystallization; mechanical properties; X-ray scattering; swelling; larvae; protein; lipid; moisture sorption; release; nanoclay; polypropylene; degradation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : This dissertation addresses the structure and properties of a number of polymer-based materials when they come into contact with specific environments. The first part describes the migration and depletion of active substances from insecticide-impregnated polyethylene sheets in water and air at different humidity levels and higher temperatures.
