  1. 1. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes

    Författare :Sumera Tubasum; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Light Harvesting Complexes; Single Molecule Spectroscopy; Polarization Spectroscopy; Exciton Dynamics; Spectral Disorder;

    Sammanfattning : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. LÄS MER

  3. 2. Fiber-based all-optical sampling for ultrafast waveform monitoring

    Författare :Mathias Westlund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polarization independent; waveform monitoring; software synchronization; four-wave mixing; all-optical sampling;

    Sammanfattning : Digital sampling is a technique to visualize a time-varying waveform by capturing quasi-instantaneous snapshots of a signal via a sampling gate. The gate is opened and closed by narrow pulses in a pulse train having a well defined repetitive behaviour such that all parts of the waveform are measured. LÄS MER

  4. 3. Localized corrosion of stainless steels in chlorine dioxide bleach filtrate solutions

    Författare :Gustaf Bäck; KTH; []
    Nyckelord :stainless steels; bleaching; chlorine dioxide; ClO2; localized corrosion; weld oxides; redox potential; potentiostatic polarization; scanning Kelvin probe;

    Sammanfattning : Stainless steels are extensively used in pulp bleach plantsbecause of their high corrosion resistance. However, alsostainless steels might suffer from corrosion and in bleachplants this is a problem. LÄS MER

  5. 4. Essays on the Transmission of Human Capital and the Impact of Technological Change

    Författare :Adrian Adermon; Mikael Lindahl; Magnus Gustavsson; Markus Jäntti; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; education; intergenerational mobility; sibling correlations; natural experiment; copyright; music; movies; file sharing; piracy; inequality; job polarization; task-biased technological change; Economics; Nationalekonomi;

    Sammanfattning : Essay 1: If grandparents have an independent impact on their grandchildren's schooling, intergenerational correlations estimated using two generations will underestimate the true level of intergenerational persistence in education. Recent research has found such multi-generational effects, but there is still no consensus on whether these estimates are due to a direct impact of grandparents on their grandchildren, or if they arise because of measurement error or model misspecification.
