  1. 1. Enzyme Printed Fabrics : Bio‐functionalisation of Synthetic Textiles by Digital Inkjet Printing

    Författare :Tuser Biswas; Vincent Nierstrasz; Junchun Yu; Tzanko Tzanov; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital printing; inkjet; enzyme; printhead; rheology; immobilisation; piezoelectric; drop-on-demand; resource-efficient textiles; biological ink; lysozyme; tyrosinase; polyphenol oxidase; polyethylene terephthalate; polyester; polyamide-6; 6; nylon; surface modification; plasma; antimicrobial; antibacterial; Textil och mode generell ; Textiles and Fashion General ;

    Sammanfattning : This thesis explores the possibilities of printing enzymes using resource-efficient technologies to promote the binding of other proteins and biomaterials on synthetic textiles. This strategy can be used to develop advanced textiles for applications, for example, in antimicrobial, drug delivery and biosensing. LÄS MER

  3. 2. New approaches to preparation of macroporous monoliths for use in liquid chromatography

    Författare :Anh Mai Nguyen; Knut Irgum; Tatiana B. Tennikova; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monolith; polycondensation; dissolution-precipitation; epoxy-amine; poly-amide; nylon; emulsion polymerization; characterization; protein separation; liquid chromatography; Analytical chemistry; Analytisk kemi; analytisk kemi; Analytical Chemistry;

    Sammanfattning : High performance liquid chromatography (HPLC) is one of the major techniques in separat-ion sciences. Faster separation and higher efficiency are required to meet ever-growing demands. Despite numerous studies and achievements on improving mass transfer in particulate packings discontinuity seems to be the cornerstone drawback in their development. LÄS MER

  5. 4. Analytical techniques for quality assessment of separated and commingled recycled polymer fractions

    Författare :Walker Camacho; KTH; []
    Nyckelord :recycling; hdpe; pp; blends; nylon 6.6; abs; water content; mae; gc-ms; mir; chemiluminiscence;

    Sammanfattning : Different methods for quality assessment of separated andcommingled plastics from household and electronic waste havebeen developed. Especial attention has been given tospectroscopic methods since they are non-destructive andrequire little or no sample preparation at all. LÄS MER

  7. 5. Group (IV) Metal-Catalyzed Direct Amidation : Synthesis and Mechanistic Considerations

    Författare :Helena Lundberg; Adolfsson Hans; Tom Sheppard; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catalysis; amide; carboxylic acid; amino acid; titanium; zirconium; hafnium; organisk kemi; Organic Chemistry;

    Sammanfattning : The amide unit constitutes the backbone of proteins, and it is present in a large number of pharmaceutically active molecules, polymeric materials such as nylon and Kevlar, as well as in food additives like aspartame. Amides are produced in enormous amounts every year, thus, environmentally friendly and selective methods for their formation are of great importance. LÄS MER
