  2. 1. Method development for affinity capillary electrophoresis of ß2-glycoprotein I and biological ligands

    Author : Maria E. Bohlin; Lars G Blomberg; Niels H H Heegaard; Jan Leo Reubsaet; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Capillary Electrophoresis; β2-glycoprotein I; acidic pretreatment; pH hysteresis effect; Affinity Capillary Electrophoresis; Kemi; Chemistry;

    Abstract : The final goal of this study is to establish a microscale analysis method that allows solution phase characterization of interactions between β2-glycoprotein I (β2gpI) and some of its ligands. Human β2gpI is a phospholipid- and heparin-binding plasma glycoprotein. READ MORE

  4. 2. Biochemical conversion of biomass : hydrothermal pretreatment, by-product formation, conditioning, enzymatic saccharification, and fermentability

    Author : Dimitrios Ilanidis; Leif J. Jönsson; Carlos Martin; Björn Alriksson; Eulogio Castro; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lignocellulosic biomass; hydrothermal pretreatment; enzymatic digestibility; ethanolic fermentation; microbial inhibitors; conditioning;

    Abstract : Lignocellulosic residues have great potential as feedstocks for production of bio-based chemicals and fuels. One of the main routes is biochemical conversion, which typically includes pretreatment, enzymatic saccharification, microbial fermentation of sugars, and valorization of hydrolysis lignin.

    Abstract : The aim of this work has been to increase knowledge of the influence of the metal ion content in softwood kraft pulp on peroxide bleaching and to investigate the effects of different metal management procedures at various stages in the production of TCF pulps (i.e. READ MORE

  6. 4. Pre-Extraction of Wood Components Mild hydrothermal methods for a future materials biorefinery

    Author : Joanna Wojtasz-Mucha; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spruce; forest residues; pre-treatment; Biorefinery; soda cooking; hot water extraction; steam explosion; autohydrolysis; birch; kraft cooking;

    Abstract : Today there is an increasing urgency in discovering new, and more sustainable, replacements for fossil-based materials and chemicals. The biorefinery concept is promising in this context in that it relies on transforming biomass into a spectrum of commercial products. Wood is the primary bioresource in Scandinavia. READ MORE

  7. 5. Chemical Modification of Nanostructured Wood for Functional Biocomposites

    Author : Shennan Wang; Qi Zhou; Gustav Nyström; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; nanostructured materials; nanocellulose; delignification; oxidation; crosslinking; amination; MOFs; transparent film; hydrogel; aerogel; biocomposites; mechanical properties; thermochromic materials; CO2 capture; protein immobilization.; Biotechnology; Bioteknologi;

    Abstract : Recently emerged top-down processing concept has provided new insights into the chemical modification of wood at the nanoscale. Nanostructured wood with naturally aligned cellulose microfibrils, cell wall nanoporosity, and precisely tuned chemical composition has opened up numerous possibilities for advanced design of functional materials.
