  2. 16. Hemicelluloses from Agricultural and Forestry Crops Isolation, Characterisation, and Enzymatic Hydrolysis

    Author : Alexandra Andersson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; Physical chemistry; Fysikalisk kemi; enzymology; hydrogels; Plant biochemistry; Växtbiokemi; Proteins; a-galactosidase; b-mannanase; hemicellulase; corn fibre; barley husks; spruce; size-exclusion chromatography; arabinoxylan; microwave irradiation; steam pretreatment; membrane filtration; hemicellulose; galactoglucomannan;

    Abstract : Hemicelluloses are tremendous sources of renewable raw materials, which utilisation have the potential to be highly increased in the future. Hemicelluloses are among the major groups of compounds in plant cell walls, together with cellulose and lignin. These three components are closely associated, making them difficult to separate from each other. READ MORE

  4. 17. Antibacterial elastomeric materials for biomedical applications

    Author : Annija Stepulane; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydrogels; antibacterial coating; polydimethylsiloxane; elastomer blends; drug-delivery; antimicrobial peptides;

    Abstract : An ageing population in combination with scientific and clinical advancements have led to a steady increase in the use of medical devices. Elastomeric biomaterials – materials displaying rubber-like mechanics – have found widespread applicability in the production of both short- and long-term medical devices. READ MORE

  5. 18. 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

  6. 19. Materials Based on Protein Nanofibrils

    Author : Xinchen Ye; Mikael S. Hedenqvist; Christofer Lendel; Richard T. Olsson; Jonny Blaker; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; protein nanofibrils; whey protein; hydrogel; film; microfibre; protein structure; mechanical properties;

    Abstract : Protein nanofibrils (PNFs) prepared from whey protein isolate (WPI) at low pH and elevated temperature were processed into materials, i.e. hydrogels, films, foams, and fibres, for different applications where they could potentially be sustainable alternatives to petroleum-based polymers.

  7. 20. Organs-on-chips for the pharmaceutical development process : design perspectives and implementations

    Author : Jonas Christoffersson; Carl-Fredrik Mandenius; Danny van Noort; Peter Sartipy; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Organs-on-chips; cell culture models; pharmaceutical development; microfluidics;

    Abstract : Organs-on-chips are dynamic cell culture devices created with the intention to mimic organ function in vitro. Their purpose is to assess the toxicity and efficacy of drugs and, as early as possible in the pharmaceutical development process, predict the outcome of clinical trials. READ MORE
