  1. 21. Deactivation of commercial three-way catalysts: effect of the thermal ageing

    Författare :Anna Fathali; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BET; methane production from E85; NOx reduction by methane; Rhodium; TWC; OSC; Automotive exhaust control; Palladium; Aging;

    Sammanfattning : This licentiate thesis is a summary of my study on thermal deactivated commercial threeway catalysts (TWCs). The experiments were performed using gasoline and a E85 fuelmixture of 85 vol.% ethanol and 15 vol.% gasoline. LÄS MER

  3. 22. Characterization of conjugated protease inhibitors

    Författare :Erika Billinger; Gunnar Johansson; Boris Turk; Uppsala universitet; []
    Nyckelord :Serine protease inhibitors; conjugation; immobilization; leupeptin analogues; potato serine protease inhibitor; soluble carriers; inorganic carriers.; Biokemi; Biochemistry;

    Sammanfattning : The overall theme of this thesis is a step by step approach for the design and characterization of conjugated protease inhibitors. This involves both a new assay method for protease activity and protease inhibition (paper I), a study of the stoichiometry for protease inhibitor interaction (paper II), design of inhibitory peptides (paper IV) and the construction of inhibitor conjugates (paper III & IV).

  4. 23. Design of Transition-Metal Nitride Thin Films for Thermoelectrics

    Författare :Sit Kerdsongpanya; Per Eklund; Björn Alling; Gunilla Wingqvist; Lars Hultman; Daniel Gall; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Thermoelectric devices are one of the promising energy harvesting technologies, because of their ability to convert heat (temperature gradient) to electricity by the Seebeck effect. Furthermore, thermoelectric devices can be used for cooling or heating by the inverse effect (Peltier effect). LÄS MER

  5. 24. Prussian blue analogue copper hexacyanoferrate : Synthesis, structure characterization and its applications as battery electrode and CO2 adsorbent

    Författare :Dickson Odhiambo Ojwang; Gunnar Svensson; Jekabs Grins; Andrew Goodwin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copper hexacyanoferrate; synthesis; structure refinement; thermal dehydration; CO2 adsorption; kinetic analysis; in operando synchrotron X-ray diffraction; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Prussian blue (PB) and Prussian blue analogues (PBAs) are compounds with potential applications in a large variety of fields such as gas storage, poison antidotes, electrochromism, electrochemistry and molecular magnets. The compounds are easy to synthesize, cheap, environmentally friendly and have been pursued for both fundamental research and industrial purposes. LÄS MER

  7. 25. Some Experimental and Theoretical Aspects of Combustion Chemistry

    Författare :Margaret Simonson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : An experimental apparatus is presented and discussed in terms of the range of combustion systems that can be studied using this apparatus. Based on this characterisation the effect of flame stoichiometry on the production of dioxin precursors is discussed. LÄS MER
