  1. 1. The variability in Salix BVOC emissions and possible consequences for managed SRC plantations

    Author : Tomas Karlsson; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Salix; BVOCs; varieties; age; branch chamber; leaf chambe; GC-MS; aerosols; Salix; BVOCs; varieties; age; branch chamber; leaf chamber; GC-MS; aerosols;

    Abstract : Willow (Salix spp.) trees have been used commercially since the 1980s to produce renewable energy. Some benefits with these trees are that they can clean soil from heavy metals, reduce the risk of nutrient leakage and eutrophication. READ MORE

  4. 4. Auroral Electric Fields From Satellite Observations and Numerical Modelling

    Author : Tomas Karlsson; KTH; []
    Keywords : Satellite measurements; electric fields; ionosphere; magnetosphere; diverging electric fields; downward current region; black aurora; westward travelling surge; auroral bulge; subauroral ion drifts SAID ; subauroral electric fields SAEF ; mid-latit; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis is about electrodynamics of thehigh-latitude/auroral region of near-Earth space. The work ismainly based on electric field measurements made by the doubleprobe instrument on the Freja satellite at altitudes ofapproximately 800-1700 km, together with measurements fromother instruments on the same satellite, and ground-basedinstrumentation.

  5. 5. Time Correlated Single Photon Spectroscopy on Pyramidal Quantum Dots

    Author : Tomas Jemsson; Fredrik Karlsson; Per-Olof Holtz; Sytjugov Ilya; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Generation of non-classical light is both of fundamental interest and a common condition for quantum information applications (QIA). One feasible type of single photon emitter for QIA is based on semiconductor quantum dots (QDs), due to their atomic-like energy structure and their possibility to be integrated with other semiconductor devices on the same chip.
