  1. 11. From microstructure to subsurface characterization. Spectral information from field scale time domain induced polarization

    Författare :Sara Johansson; Teknisk geologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geofysik; Inducerad Polarisation;

    Sammanfattning : A large variety of subsurface infrastructure projects of different types can gain valuable information from tomographic measurements of subsurface physical properties. With resistivity and time domain spectral induced polarization (IP), the distributions of the conductive and capacitive properties of the subsurface are obtained. LÄS MER

  4. 13. Multimethod characterization of a chlorinated solvents contaminated site and geoelectrical monitoring of in-situ bioremediation

    Författare :Aristeidis Nivorlis; Teknisk geologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geoelectrical monitoring; induced polarization 1P ; contamination remediation geophysics; Time-lapse inversion; autonomous geophysical monitoring;

    Sammanfattning : Soil contamination is a widespread problem and actions need to be taken in order toprevent damage to the groundwater and the life around the contaminated sites. InSweden more than 80.000 sites are potentially contaminated, therefore there is ademand for accurate and efficient methods for site characterization and soilremediation. LÄS MER

  5. 14. Measurements and simulations of thermoplasmonically induced Marangoni flows

    Författare :Pantea Dara; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microbubbles; optical force microscopy; Marangoni flow; thermoplasmonics; microfluidics;

    Sammanfattning : Particle transport in microfluidic environments is often dominated by slow diffusion near interfaces. However, by inducing localized fluid flow, it is possible to actively transport suspended nano-objects in confined spaces. LÄS MER

  7. 15. Polarization-resolved photoluminescence spectroscopy of III-nitride quantum dots

    Författare :Supaluck Amloy; Fredrik Karlsson; Per-Olof Holtz; Jørn M. Hvam; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis, results from studies on (In)GaN quantum dots (QDs) are presented, including investigations of the structural, optical and electronic properties. The experimental studies were performed on GaN and InGaN QDs grown by molecular beam epitaxy, taking advantage of the Stranki-Krastanov growth mode for the GaN QD samples and the composition segregation for the InGaN QD samples.
