  2. 16. Ice out of Fire : Ice and cloud condensation nucleation of aerosol particles emitted from controlled soot generation and combustion of renewable fuels

    Author : John Falk; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Soot; BC; Immersion freezing; IN; INP; CCN; SPIN; CCNC; MiniCAST; Cold Stage; Cook Stove;

    Abstract : Aerosol particles, small solid or liquid particles suspended in a gas, are found everywhere in the atmosphere. Air pollution from such particles, mainly soot from combustion-derived activity is a leading cause of premature deaths in the world and have a large effect on the climate. READ MORE

  4. 17. InGaN Quantum Dots Grown on GaN Pyramid Arrays

    Author : Chih-Wei Hsu; Per Olof Holtz; Robert A. Taylor; Linköpings universitet; []
    Keywords : ;

    Abstract : Selective-area growth (SAG) of InGaN on GaN pyramids, which allows the formation of additional hybrid quantum structures, including quantum wires and quantum dots (QDs) in a site-controlled fashion, is attractive for both fundamental research and device application. The site-controlled growth of QDs showing sharp emission lines is seen as the first step toward the frontier quantum information application (QIA). READ MORE

  5. 18. Controlling the Fluorescence Properties of Diarylethene-based Photochromic Systems

    Author : Gaowa Naren; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; isomerization; color change; photochromic molecules; molecular logic; intensity modulation; diarylethene; RGB; all-photonic; FRET;

    Abstract : Diarylethene (DAE) photoswitches are one of the most promising families of photochromic molecules because of their outstanding photophysical/photochemical properties. This class of compounds, which can photoisomerize between an open colorless and a closed colored form, has been applied in various fields in this thesis work, spanning one-color fluorescence intensity modulation, all-photonic full-color reproduction, light-induced color changes for molecular logic gates and information processing.

  6. 19. Time Correlated Single Photon Spectroscopy on Pyramidal Quantum Dots

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

    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.

  7. 20. Excited state dynamics in the strong coupling regime

    Author : Jürgen Mony; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Strong exciton-photon coupling; Excited state dynamics; light-matter interactions; photoswitch; aggregated states;

    Abstract : Strong exciton-photon coupling exhibits the possibility to modify photophysical and photochemical properties of organic molecules without changing their structure. This is due to the formation of hybrid light-matter states, called polaritons, which are created when the strong coupling regime is achieved. READ MORE
