  1. 1. Functional and Renewable Galactoglucomannan-based Hydrogels

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Jens Voepel; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polysaccharides; hydrogels; swelling; crosslinking; hemicellulose; release; polysackarider; hemicellulosa; hydrogel; läkemedelsfrisättning; förnyelsebar; tvärbindning.; TECHNOLOGY Materials science Functional materials; TEKNIKVETENSKAP Teknisk materialvetenskap Funktionella material;

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

  2. 2. On the phase behaviour of hydrogels A theory of macroion-induced core/shell equilibrium

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jonas Gernandt; Uppsala universitet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; polymer; polyelectrolyte; surfactant; thermodynamics; elasticity; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : Colloidal macroions are known to interact very strongly with oppositely charged polyionic hydrogels. Sometimes this results in a non-uniform distribution of the macroions within the gel, a phenomenon that is not fully understood. READ MORE

  3. 3. Structural design and properties of hydrogel biomaterials

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mikael Larsson; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Hydrogels; Microfibrillated cellulose; Drug release; Chitosan; Biomaterials; Polyacrylic acid; Swelling; Mechanical properties;

    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. 4. Properties and Applications of Temperature Sensitive Gels

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Matz Andersson; [1996]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Swelling kinetics; Poly N-isopropylacrylamide gel; NiPAAm; Immobilisation; Hydrogels; Gel extraction; Flory-Huggins; Diffusion; Controlled Release; Kemiteknik och kemisk teknologi;

    Abstract : The work presented deals with the characterisation and application of critical gels. In order to provide a theoretical foundation, the thermodynamics of the reversible swelling and shrinking behaviour of such gels is outlined. The temperature-sensitive poly(N-isopropylacrylamide) gel (NiPAAm) was chosen for experimental investigation. READ MORE

  5. 5. Chitin nanofibers, networks and composites Preparation, structure and mechanical properties

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Ngesa Ezekiel Mushi; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chitin; chitin materials; membranes; hydrogels; nanocomposites; mechanical properties; bioinspiration; lobster; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Chitin is an important reinforcing component in load-bearing structures in many organisms such as insects and crustaceans (i.e. shrimps, lobsters, crabs etc.). READ MORE
