  1. 1. Heterogeneous Degradation and Recyclability of PP Studied by Imaging Chemiluminescence

    University dissertation from KFS AB

    Author : Mikael Hamskog; Lund University.; Lunds universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Teknik; Technological sciences; recyclability; mapping; surface; heterogeneity; heterogeneous; evaporation; ageing; hamamatsu; russel; ICL; CL; Irganox 1010; Irganox 1076; oxidation; hydroperoxide; radical; carbonyl; luminescence; chemiluminescence; imaging chemiluminescence; recycling; stabilization; polypropylene; degradation;

    Abstract : Oxidative degradation is a serious threat to long-term use and recyclability of polymers. Successful recycling of polymeric quality products requires characterization of the polymer material after reprocessing and use. READ MORE

  4. 4. Theoretical Studies of Ground and Excited State Reactivity

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Pooria Farahani; Uppsala universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemical Reactivity; Computational Chemistry; Dynamics; Ground and Excited States; Chemiluminescence; Atmospheric Chemistry;

    Abstract : To exemplify how theoretical chemistry can be applied to understand ground and excited state reactivity, four different chemical reactions have been modeled. The ground state chemical reactions are the simplest models in chemistry. To begin, a route to break down halomethanes through reactions with ground state cyano radical has been selected. READ MORE

  5. 5. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners

    University dissertation from Department of Physics, Lund University

    Author : Arman Subash; Lund University.; Lunds universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Combustion; Gas turbine; Chemiluminescence; laser-based techniques; LIF; PIV; DLE; TARS; CH4; H2; OH; CH20; Equivalence ratio; flame stabilization; LBO; Flashback; RPL; Fysicumarkivet A:2018:Subash;

    Abstract : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. READ MORE
