  2. 1. Nanoporous Aluminum Oxide – A Promising Support for Modular Enzyme Reactors

    Author : Marcus Kjellander; Gunnar Johansson; Gunnar Henriksson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nanoporous aluminum oxide; immobilized enzymes; bioreactor; Biokemi; Biochemistry;

    Abstract : Nanoporous alumina is a rather newly characterized material that so far has found limited use in the construction of bioreactors. The material has many advantages compared to conventional immobilization matrices. I have investigated its use in flow-through bioreactors. READ MORE

  4. 2. Understanding the Influence of Wood Extractives on Off-Gassing during Storage of Wood Pellets

    Author : Workson Siwale; Jonas Berghel; Gunnar Henriksson; Michael Finell; Stefan Frodeson; Gunnar Johansson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Off-gassing; Carbon Monoxide; Carbon Dioxide; Methane; Self-heating; Additive Oils; Fatty and Resin Acids; Solid Biofuels; Miljö- och energisystem; Environmental and Energy Systems;

    Abstract : Wood pellets have become a solid biomass fuel of choice because they are a standardized product with known quality properties. However, the self-heating and off-gassing tendencies during storage of wood pellets threatens the consistency of the pellets’ quality properties. READ MORE

  5. 3. Biochemical Study and Technical Applications of Fungal Pectinase

    Author : Jing Zhang; Gunnar Johansson; Gunnar Henriksson; Jonas Hafrén; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Pectin; pectinase; polygalacturonan; polygalacturonase; retting; flax; enzymatic retting; pre-incubation; discoloration; pulping; Biokemi; Biochemistry; Biokemi;

    Abstract : Pectinases are a group of enzymes produced by bacteria, fungi, higher plants and animals. Pectinases can modify and degrade pectins, a class of heterogeneous and multifunctional polysaccharides present in middle lamellae and primary cell walls of plants. READ MORE

  7. 5. Nanosecond tandem optical parametric oscillators for mid-infrared generation

    Author : Markus Henriksson; Fredrik Laurell; Gunnar Rustad; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; optical parametric oscillators; quasi-phase matching; mid-infrared; linewidth narrowing; volume Bragg gratings.; Physics; Fysik;

    Abstract : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. READ MORE
