  1. 16. Using patient-derived cell models to investigate the role of misfolded SOD1 in ALS

    Författare :Elin Forsgren; Jonathan Gilthorpe; Stefan Marklund; Peter Andersen; Thomas Brännström; Ulrika Nordström; Séverine Boillée; Umeå universitet; []
    Nyckelord :ALS; SOD1; patient-derived models; induced pluripotent stem cells; motor neurons; astrocytes; 20S proteasome low oxygen tension; misfolded SOD1; Neurology; neurologi;

    Sammanfattning : Protein misfolding and aggregation underlie several neurodegenerative proteinopathies including amyotrophic lateral sclerosis (ALS). Superoxide dismutase 1 (SOD1) was the first gene found to be associated with familial ALS. LÄS MER

  3. 17. Evaluation of volatile organic compounds related to board based packaging by use of instrumental and sensory analysis

    Författare :Gunnar Forsgren; Fredrik Winquist; Ola Karlsson; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The main topic of the thesis is characterisation and evaluation of volatile organic compounds emitted by packaging materials based on paperboard products. The properties and concentration of these compounds are critical to how well these materials perform when applied as a main component of food packaging. LÄS MER

  4. 18. Functional Ceramics in Biomedical Applications : On the Use of Ceramics for Controlled Drug Release and Targeted Cell Stimulation

    Författare :Johan Forsgren; Håkan Engqvist; Strømme Maria; Susanne Bredenberg; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Controlled release; geopolymer; sol-gel; opioid; oral administration; oral dosage form; implant; titanium; hydroxyapatite; infection; strontium carbonate; strontium; Functional materials; Funktionella material; Materials science; Teknisk materialvetenskap; Material physics with surface physics; Materialfysik med ytfysik; Teknisk fysik med inriktning mot nanoteknologi och funktionella material; Engineering Science with specialization in Nanotechnology and Functional Materials;

    Sammanfattning : Ceramics are distinguished from metals and polymers by their inorganic nature and lack of metallic properties. They can be highly crystalline to amorphous, and their physical and chemical properties can vary widely. LÄS MER

  5. 19. Physical properties of dispersions and composites containing surface-grafted cellulose nanocrystals

    Författare :Lilian Forsgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite; Cellulose; Thermal stability; Cellulose nanocrystals; Tensile properties; Rheology;

    Sammanfattning : The needs and requests from the society for non-fossil-based materials as well as more lightweight products are constantly increasing. The increasing awareness of the sustainability of the resources available paralleled by a growing population, point to a need for changes, if the population also aim for constantly higher standard of living.

  7. 20. Processing and properties of thermoplastic composites containing cellulose nanocrystals or wood-based cellulose fibres

    Författare :Lilian Forsgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extrusion; Cellulose nanocrystals; Cellulose; Thermal stability; Tensile properties; Wood-based fibres; Injection moulding; Composite;

    Sammanfattning : Cellulose nanocrystals (CNC) were surface modified with dialkylamines to increase the compatibility between the CNC and the polymeric matrix, and promising results were obtained, with a 300 % stiffness increase when the mixed dispersion was compression moulded on a laboratory scale. The manufacturing process was up-scaled using water-assisted mixing in a twin-screw extruder (TSE) followed by a second compounding step and injection moulding (IM). LÄS MER
