  2. 1. Kinetic investigations of combustion of small oxygenated aliphatic hydrocarbons – modeling and experiments

    Author : Gianluca Capriolo; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modelling; Nitric Oxide; n-propanol; i-propanol; propanal; LIF; Fysicumarkivet A:2020:Capriolo;

    Abstract : The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. READ MORE

    Abstract : Statistical experimental designs have been used for method development and optimisation of separation. Two reversed phase HPLC methods were optimised. READ MORE

  6. 4. Gas Sensing Based on Ellipsometric Readout : Methodology and Development

    Author : Guoliang Wang; Herbert Wonneester; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The concept of an ellipsometric sensor array system - "an optical nose" - is presented. The system is used to monitor and discriminate gases. The optical readout is based on polarizer-compensator-sample-analyzer (PCSA) off-null ellipsometry. READ MORE

  7. 5. Development of Mild Methods for Selective Covalent Functionalization of Graphene

    Author : Anna Lundstedt; Grennberg Helena; Bo Wegge Laursen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polycyclic aromatic hydrocarbons; graphene models; graphite; local ionization energy surfaces; graphene functionalization; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Abstract : This thesis discusses methods for the comparatively mild covalent functionalization of graphene. Several graphene models were investigated: polycyclic aromatic hydrocarbons (PAHs), chemical vapor deposition (CVD)-graphene on SiO2/Si substrate, graphite foil, graphite flakes, kish graphite and highly oriented pyrolytic graphite.
