    Abstract : Sustainable energy sources are of great importance, and will become even more important in the future. Gasification of biomass is an important process for utilization of biomass, as a renewable energy carrier, to produce fuels and chemicals. READ MORE

  2. 2. Environmental filtering of bacteria in low productivity habitats

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Inga Richert; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; bacteria; environmental filtering; diversity; ecosystem service; hydrocarbon utilization; Southern Ocean; sediment; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

    Abstract : Microbes fulfill important ecosystem functions by contributing as drivers of global nutrient cycles. Their distribution patterns are mainly controlled by environmental heterogeneities. So far, little is known about the mode of action of particular environmental drivers on the microbiota, particularly in low productivity habitats. READ MORE

  3. 3. Design and analysis of solid oxide electrolysis-based systems for synthetic liquid fuels production

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Mahrokh Samavati; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid oxide electrolyser; Entrained gasification; Fischer-Tropsch process; Thermodynamic analysis; Economy; Emission saving; Policy; Energiteknik; Energy Technology;

    Abstract : During the past decades, considerable attention has been dedicated to renewable energy systems. This is due to the increased awareness regarding greenhouse gas emissions as well as limits of the future availability and reliability of conventional energy and power systems. READ MORE

  4. 4. RNA in model lipid membranes - interactions in bulk and at surfaces

    University dissertation from Department of Chemistry, Lund University

    Author : Agnes Michanek; Lund University.; Lunds universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ssRNA; RNA origami; dsDNA; selfassembly phospholipids; model membranes; monolayer; QCM-D; DSC; Neutron reflectometry; hydrophobic interaction; cationic surfactants; sphingosine; phase behavior;

    Abstract : The work presented in the thesis “RNA in model lipid membranes- interactions in bulk and at surfaces” aims to characterize the interaction between RNA and model membranes with different properties as well as to determine if ssRNA associate with model membranes in different ways. Several techniques have been used to characterize these systems, including quartz crystal microbalance with dissipation monitoring (QCM-D), Langmuir film balance in combination with neutron reflectometry and fluorescence microscopy as well as differential scanning calorimetry (DSC) and isothermal titration calorimetry (ITC).

  5. 5. Metabolic Engineering of Saccharomyces cerevisiae for Sesquiterpene Production

    University dissertation from Department of Chemistry, Lund University

    Author : Gionata Scalcinati; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Systems Biology; Saccharomyces cerevisiae.; Evolutionary engineering; Metabolic Engineering; Microrefinery; Cell factory; Synthetic Biology;

    Abstract : Industrial biotechnology aims to develop robust “microbial cell factories”, to produce an array of added value chemicals presently dominated by petrochemical processes. The exploitation of an efficient microbial production as sustainable technology has an important impact for our society. READ MORE
