  2. 1. Two-Line Atomic Fluorescence for Thermometry in Reactive Flows

    Author : Jesper Borggren; Förbränningsfysik; []
    Keywords : Two-line atomic fluorescence; thermometry; Laser spectroscopy; Diode laser; Fysicumarkivet A:2018:Borggren;

    Abstract : Advances in the field of laser-based combustion diagnostics over the past decades have allowed for detailed characterisation, modelling and increased understanding of the complex combustion process. However; many combustion phenomena are still unexplained and there is a continued need for development and application of diagnostic tools to further the understanding of the combustion process.

  4. 2. Single-­molecule spectroscopy of π-­conjugated polymers

    Author : Oleg Mirzov; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluorescence lifetime; low temperature; spectral diffusion; blinking; MEH-PPV; Single-molecule spectroscopy; π-conjugated polymers; 2D polarization; Monte Carlo; energy transfer;

    Abstract : When applied to condensed-matter samples of large organic molecules, optical spectroscopy faces the problem of inhomogeneous broadening caused by the diversity of environments and conformations that sample molecules are subjected to. This severely limits the information that can be extracted from optical spectra. READ MORE

  5. 3. Storage Stability and Phase Separation Behaviour of Polymer-Modified Bitumen : Characterization and Modelling

    Author : Jiqing Zhu; Niki Kringos; Dallas Little; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymer-modified bitumen; Storage stability; Phase separation; Fluorescence microscopy; Phase-field modelling; Polymermodifierad bitumen; Lagringsstabilitet; Fasseparation; Fluorescensmikroskopi; Fas-fälts modellering; Transportvetenskap; Transport Science;

    Abstract : Polymer-modified bitumen (PMB) is a high-performance material for road construction and maintenance. But its storage stability and phase separation behaviour are still not sufficiently understood and need to be studied toward a more successful and sustainable application of PMB. READ MORE

  6. 4. Mechanisms of insulin exocytosis and release

    Author : Sebastian Barg; Islet cell physiology; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ClC-3; electrophyiology; confocal microscopy; calcium channel; readily releasable pool; exocytosis; insulin; diabetes; green fluorescent protein; Physiology; Fysiologi;

    Abstract : Endocrine cells as well as neurons release their hormones and transmitters by regulated exocytosis. In the pancreatic B-cell, stimuli like glucose initiate biochemical and electrical processes that culminate in influx of Ca2+, which then triggers exocytosis of insulin-containing granules.
