  1. 6. New Tools for Trapping and Separation in Gas Chromatography and Dielectrophoresis : Improved Performance by Aid of Computer Simulation

    Författare :Fredrik Aldaeus; Anders Colmsjö; Marja-Liisa Riekkola; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; gas chromatography; dielectrophoresis; computer simulation; finite element method; trapping; separation; lab-on-a-chip; Analytical chemistry; Analytisk kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Computer simulations can be useful aids for both developing new analytical methods and enhancing the performance of existing techniques. This thesis is based on studies in which computer simulations were key elements in the development of several new tools for use in gas chromatography and dielectrophoresis. LÄS MER

  4. 8. Advances in Holographic Optical Trapping

    Författare :Martin Persson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical tweezers; Holographic optical trapping; Optical force measurement; Spatial light modulators; Holographic beam steering; Liquid crystals;

    Sammanfattning : Holographic optical trapping (HOT) is a technique for non-invasive dynamic anipulation of multiple microscopic objects, which has been used for many applications in the life sciences during the past decade. The technique uses holographic beam steering with a spatial light modulator (SLM) to direct light to the desired positions of optical traps. LÄS MER

  5. 9. Evolutionary Genomics of Nematode-Trapping Fungi

    Författare :Tejashwari Meerupati; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nematode-trapping fungi; Comparative Genomics; Comparative Transcriptomics; Differential gene expression; Gene duplication; Parasitism; Protein family expansion.;

    Sammanfattning : Nematode-trapping fungi are ubiquitous, soil-living organisms with the ability to infect and kill nematodes. These fungi have developed specialized infection structures for the capture of nematodes. LÄS MER

  7. 10. Residual and Solubility trapping during Geological CO2 storage : Numerical and Experimental studies

    Författare :Maria Rasmusson; Fritjof Fagerlund; Auli Niemi; Jonathan Ennis-King; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; capillary trapping; CCS; convective flow; CO2; light transmission; SO2; well test; Hydrology; Hydrologi;

    Sammanfattning : Geological storage of carbon dioxide (CO2) in deep saline aquifers mitigates atmospheric release of greenhouse gases. To estimate storage capacity and evaluate storage safety, knowledge of the trapping mechanisms that retain CO2 within geological formations, and the factors affecting these is fundamental. LÄS MER
