  1. 6. Preparation and Characterization of Macroporous Cryostructured Materials

    Författare :Harald Kirsebom; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Macroporous hydrogels are regarded as interesting materials both within biotechnology and biomedicine due to their properties. These materials can be prepared from a wide range of synthetic or naturally occurring compounds using a number of different techniques for their production. LÄS MER

  3. 7. Synthesis and Characterization of Functional Polymers Based on Trimethylolpropane Trimethacrylate and Glycidyl Methacrylate

    Författare :Maria Walenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ethylhydroxyethyl cellulose derivative; trimethylolpropane; gels; compression; separation; pore surface; trimethacrylate; Copolymers;

    Sammanfattning : Copolymers of trimethylolpropane trimethacrylate (TRIM) and glycidyl methacrylate (GMA) were prepared with various monomer-to-solvent ratios, GMA to TRIM ratios and with various types of porogens. These parameters affected the inner morphology of the polymers and various pore surface areas (100-500 m2/g) and pore size distributions were obtained. LÄS MER

  4. 8. Composite Cryogels: Stationary Phase for Separation of Complex Media

    Författare :Solmaz Hajizadeh; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite cryogel; Complex media; Purification; Chromatography; Environmental application; Molecularly imprinted polymer;

    Sammanfattning : Demands for efficient, economical and fast separation and purification methods for various target molecules have led to the development of new techniques and materials for bioseparation processes. Separation can be carried out in both batch and chromatographic modes. LÄS MER

  5. 9. Modification of microcapsules for controlled release

    Författare :Markus Andersson Trojer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; block copolymer; coordination chemistry; polyelectrolyte multilayer; cross-linking; vibrational spectroscopy; electron paramagnetic resonance; imidazole; controlled release; colloidal stability; Microcapsule; quartz crystal microbalance with dissipation;

    Sammanfattning : Fouling of marine organisms such as algae and barnacles on the boat hull is an enormous problem for the shipping industry. The negative consequences for the society are both economical and environmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER

  7. 10. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Författare :Mathieu Le Noir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Sammanfattning : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. LÄS MER
