  2. 16. Nanostructure and biomolecule interactions : Characterizing the complex

    Author : Stefan Gunnarsson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanostructures; Proteins; Lipids; Protein corona; Aggregation; Sedimentation; Diffusion; Electron microscopy; Enzyme activity; Nanowires; Nanoparticles;

    Abstract : This thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. READ MORE

  4. 17. Tailoring Cellulose Nanofibrils for Advanced Materials

    Author : Núria Butchosa Robles; Qi Zhou; Kristiina Oksman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose nanofibrils; bacterial cellulose; surface modification; carboxymethyl cellulose; polyethylene glycol; chitin nanocrystals; bactericidal activity; nanofibrils orientation; water redispersability; mechanical properties; dye removal; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Cellulose nanofibrils (CNFs) are nanoscale fibers of high aspect ratio that can be isolated from a wide variety of cellulosic sources, including wood and bacterial cellulose. With high strength despite of their low density, CNFs are a promising renewable building block for the preparation of nanostructured materials and composites. READ MORE

  5. 18. Lignocellulose Degradation by Soil Micro-organisms

    Author : Ran Bi; Gunnar Henriksson; Jerry Ståhlberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lignocellulosic biomass is a sustainable resource with abundant reserves. Compared to petroleum ‐ based products, the biomass ‐ derived polymers and chemicals give better environmental profiles. A lot of research interest is focused on understanding the lignocellulose structures. READ MORE

  6. 19. Long-Term Tracheostomy : Outcome, Cannula care, and Material Wear

    Author : Gunilla Björling; Unn-Britt Johansson; Claes Frostell; Agneta Markström; Bengt Midgren; Sophiahemmet Högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long-term tracheostomy; Respiratory failure; Hospital care; Tracheostomy care; Decontamination; Trachestomy tube; Material degradation; Polymeric material; Health-related quality of life; Nursing; Omvårdnad; Long-term tracheostomy; respiratory failure; hospital care; tracheostomy care; decontamination; tracheostomy tube; material degradation; polymeric material; and health-related quality of life;

    Abstract : Do people with long-term tracheostomy need hospital care? Which cleaning method is most appropriate for decontamination of inner cannulae? Are tracheostomy tubes changed for rational reasons? There is clearly a lack of evidence based research in this field and the clinical guidelines available are often based on local practice. A tracheostomy is a created opening in trachea to facilitate breathing. READ MORE

  7. 20. Fermented probiotic beverage based on quinoa : Functionality, hygiene, and health effects

    Author : Pamela Rosario Canaviri Paz; Avdelningen för livsmedel och läkemedel; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quinoa grains; Fermentation; Lactic acid bacteria; Probiotics; Food safety; Starter culture; Polyphenol compounds; Microbiota composition; Functional food; Gut microbiota;

    Abstract : White quinoa grains were used as a source of novel beneficial microorganisms and as a matrix for development of a fermented plant-based drink. Studies on the quinoa grain microbiota were performed by applying spontaneous fermentation to allow isolation of autochthonous Lactiplantibacillus strains with potential to be used as starter cultures.
