  1. 1. Optical Diagnostic Techniques Applied in Practical Combustion Devices and Processes

    Detta är en avhandling från LU

    Författare :Joakim Rosell; Lunds universitet.; Lund University.; [2016-10-25]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optical diagnostics; LIF; OH; CO; CH2O; CH; Optical Engines; Fysicumarkivet A:2016:Rosell;

    Sammanfattning : Optical measurement techniques have proven to be useful tools for studying combustion-related phenomenon. The fact that the techniques are optical facilitates performing the measurements without impinging upon the measurement object, such as the combustion event that can be involved. LÄS MER

  2. 2. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines

    Detta är en avhandling från Division of Combustion Physics, Department of Physics, Lund University

    Författare :Zhenkan Wang; Lunds universitet.; Lund University.; [2018-05-04]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion diagnostics; Laser induced fluorescence LIF ; Ultra-high-speed; Burst-mode laser; Ballistic imaging; Particle imaging velocimetry; Laser Doppler anemometry; Turbulent premixed combustion; Plasma; Internal combustion engine; Partially premixed combustion PPC ; Auto-ignition; OH radical; CH2O formaldehyde ; Fysicumarkivet A:2018:Wang;

    Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER

  3. 3. Radiation Induced Processes at Solid-Liquid Interfaces

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Miao Yang; KTH.; [2015]

    Sammanfattning : In the thesis, the reactions between water radiolysis products—H2O2, HO• and O2—with metals and metal oxides utilized in nuclear industry are studied. The reactions include not only surface reactions, e.g. redox reactions and catalytic decomposition of H2O2, but also solution reactions (Haber-Weiss reactions). LÄS MER

  4. 4. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion

    Detta är en avhandling från Lund Report on Combustion Physics

    Författare :Jiajian Zhu; Lunds universitet.; Lund University.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; High-speed photography; Laser diagnostics; Planar laser-induced fluorescence; Plasma-assisted combustion; Non-thermal plasmas; Gliding arc discharge; Optical diagnostics; Particle tracking velocimetry; Fysicumarkivet A:2015:Zhu;

    Sammanfattning : Popular Abstract in Swedish Plasma består av fria elektroner, joner och neutrala partiklar och utgör det fjärde tillståndet av materia där de andra tre är fast-, flytande- och gasfas. Plasma är den vanligast förekommande tillståndet av materia i universum och uppskattas utgöra mer än 99% av universums totala massa. LÄS MER

  5. 5. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Pegah Sadat Nabavi Zadeh; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluorescence spectroscopy; dynamics; mesoporous silica; Immunogold staining; Transmission electron microscopy; anisotropy; microviscosity; real-time monitoring; Cy5.; Förster resonance energy transfer; Enzyme immobilization; Cy3;

    Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER
