  1. 1. Electron tomography and optical modelling for organic solar cells

    Författare :Viktor Andersson; Olle Inganäs; Joachim Loos; Linköpings universitet; []
    Nyckelord :Organic solar cells; Electron tomography; Optical modelling;

    Sammanfattning : Organic solar cells using carbon based materials have the potential to deliver cheap solar electricity. The aim is to be able to produce solar cells with common printing techniques on flexible substrates, and as organic materials can be made soluble in various solvents, they are well adapted to such techniques.

  3. 2. Alkali Uptake and Release from Oxygen Carriers in Chemical Looping Applications: Development and Application of Reactor Systems and Measurement Techniques

    Författare :Viktor Andersson; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali speciation; Biomass; Chemical looping combustion; Oxygen carriers;

    Sammanfattning : Chemical looping combustion (CLC) of biomass is a heat and power generation technology with minimal associated costs for carbon capture, potentially resulting in negative CO2 emissions. The CLC technology utilizes fluidized beds of oxygen carrier (OC) particles to separate CO2 from the combustion air. LÄS MER

  4. 3. Excess heat utilisation in oil refineries - CCS and algae-based biofuels

    Författare :Viktor Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; techno-economic; CO2 emissions; carbon dioxide; renewable diesel; post-combustion; algae biofuels; process integration; GHG emissions; oil refining industry; carbon capture and storage CCS ;

    Sammanfattning : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. LÄS MER

  5. 4. Structure-Magnetic Relationships in the Fe-Mn-P-Si System for Energy Applications

    Författare :Viktor Höglin; Yvonne Andersson; Per Nordblad; Martin Sahlberg; Mogens Christensen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetocaloric; X-ray powder diffraction; Neutron powder diffraction; Magnetization measurements; Phase diagram; Crystal structure; Magnetic structure; Incommensurate structure; Ferromagnetic; Antiferromagnetic; Fe2P; Fe-Mn-P-Si.; Kemi med inriktning mot oorganisk kemi; Chemistry with specialization in Inorganic Chemistry;

    Sammanfattning : Demands for new, energy-efficient appliances have greatly increased in response to our growing need for a more environmentally friendly society. Magnetic refrigeration is a technique that utilizes the magnetocaloric effect, with possible energy savings of up to 30% compared to commercial gas compression refrigerators. LÄS MER

  7. 5. Cognitive Behavioural Therapy as Guided Self-help to Reduce Tinnitus Distress

    Författare :Viktor Kaldo; Gerhard Andersson; Steven Linton; Uppsala universitet; []
    Nyckelord :Psychology; Tinnitus; Cognitive Behavioural Therapy; Self-help; Internet; Stages of Change; Psykologi;

    Sammanfattning : Tinnitus is common, and some individuals with tinnitus display high levels of distress. Cognitive behavioural therapy (CBT) is effective in reducing tinnitus distress, but is rarely available. LÄS MER
