  1. 1. Proton pathways in energy conversion K-pathway analogs in O2- and NO-reductases

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Nathalie Gonska; Pia Ädelroth; Alessandro Giuffré; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; heme-copper oxidase; cytochrome c oxidase; membrane protein; respiration; electron transfer; proton transfer; redox reaction; metalloprotein; non-heme iron; cytochrome ba3; flow-flash; carbon monoxide; liposome; respiratory control ratio; biokemi; Biochemistry;

    Abstract : Oxygen and nitric oxide reductases are enzymes found in aerobic and anaerobic respiration, respectively. Both enzyme groups belong to the superfamily of Heme-Copper Oxidases, which is further divided into several subgroups: oxygen-reducing enzymes into A-, B- and C-type and nitric oxide reductases into qNORs and cNORs.

  2. 2. Catalytic conversion of LignoBoost Kraft lignin into liquid products in near-critical water

    University dissertation from Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Author : Huyen Nguyen Lyckeskog; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LignoBoost; Catalytic conversion; Hydrothermal conversion; Bio-oil; Near-critical water; Lignin;

    Abstract : Lignin, one of the three main components of lignocellulosic biomass, is the second most abundant organic polymer found on Earth. Due to its aromatic nature, lignin is recognized as being a potential feedstock for producing transportation fuel and high value-added chemicals. READ MORE

  3. 3. Micro-reaction Mechanism Study of the Biomass Thermal Conversion Process using Density Functional Theory

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Xiaolei Zhang; Weihong Yang; Linda J. Broadbelt; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass thermal conversion; cellulose pyrolysis; char steam gasification; adsorption; interaction; mechanism; quantum chemistry; density functional theory;

    Abstract : Biomass, or bio-energy, is one of the most important alternative energies because of environmental concerns and the future shortage of fossil fuels. Multi-scaled bioenergy studies have been performed in the division of Energy and Furnace Technology, which included studies of macroscopic systems such as systems and reactors, modeling of computational fluid dynamics (CFD), and atomic/molecular level studies.
