  1. 6. Spray drying of particles intended for inhalation - Investigation of significant process variables and product characteristics, with focus on degradation and solid state properties

    Författare :Kristina Mosén; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Läkemedelsteknik och relaterad teknik; Pharmaceutical and related technologies; carbohydrate; insulin; process conditions; crystallinity; degradation; particle size; spray drying; inhalation;

    Sammanfattning : The interest in spray drying for production of inhalable particles has grown considerably since the late 1980s. However, which process variables that control degradation and the solid state properties have not been subject to extensive research. This thesis deals with how important characteristics of inhalation particles can be controlled, i.e. LÄS MER

  3. 7. Towards a pure kraft lignin

    Författare :Rufus Ziesig; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; black liquor; lignin; impurities; purification; carbohydrate; inorganics; precipitation;

    Sammanfattning : The most widely used production method for paper pulp in the world is kraft pulping. In chemical pulping the polymer, lignin, which binds the wood fibres together, is partly depolymerized. This allows the wood fibres to be separated from each other. LÄS MER

  4. 8. Hydrolysis of by-products from cereal kernels for improved ethanol production

    Författare :Beatriz Palmarola Adrados; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; starch-free fibres; Kemiteknik och kemisk teknologi; wheat starch fibres; starch-free bran; wheat bran; SSF; enzymatic hydrolysis; H2SO4; microwave pretreatment; Ethanol production; steam pretreatment;

    Sammanfattning : This work deals with the hydrolysis of lignocellulosic agricultural residues, by means of combined pretreatment and enzymatic hydrolysis, to be used for ethanol production. Four agricultural by-products, i.e. LÄS MER

  5. 9. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú

    Författare :Cristhian Carrasco; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steam pretreatment; ethanol production; SSCF; arabinosylated aromatics; SO2; H2SO4; sugarcane bagasse; paja brava; wheat straw; quinoa stalks; Anadenanthera colubrina;

    Sammanfattning : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. LÄS MER

  7. 10. The sweet side of molecular structure : NMR spectroscopic studies of glycans and their interactions with proteins

    Författare :Christoffer Hamark; Göran Widmalm; Mario Schubert; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioorganic chemistry; glycans; ligand-based NMR; molecular simulations; protein-carbohydrate interactions; lectins; carbohydrate conformations; 77Se NMR; structure-reactivity relationships; super-armed donors; organisk kemi; Organic Chemistry;

    Sammanfattning : In this thesis, within the topic of bioorganic chemistry, the molecular structure of carbohydrates has been studied. Carbohydrates, or glycans, are ubiquitous biomolecules exhibiting a wide range of biological roles. LÄS MER
