  1. 1. Long-term metal retention processes in a peat bog Field studies, data and modelling

    Detta är en avhandling från Stockholm, : KTH

    Författare :Kristina Syrovetnik; Ivars Neretnieks; Bert Allard; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Peat; heavy metals distribution; sequential extraction; binding mechanisms; modelling; metal sulphide oxidation; aqueous composition; sorption; humic substances; ferric oxyhydroxide; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : The study was inspired by the need to assess long-term metal retention in municipal solid waste (MSW) landfills. The long-term processes in landfills are poorly known due to the relatively short time that such landfills have been in existence. Natural analogues where similar metal binding processes could be expected were therefore sought for. LÄS MER

  2. 2. Modelling and experimental investigation of the porous nickel anode in the molten carbonate fuel cell

    Detta är en avhandling från Stockholm : KTH

    Författare :Mari Sparr; Göran Lindbergh; Kas Hemmes; [2005]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical engineering; molten carbonate fuel cell; MCFC; mechanism; cell modelling; porous electrode; Kemiteknik; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : The thesis is focussed on the performance of the fuel cell and the design of the cell for operation with natural gas and renewable fuels, e.g. biogas or gasified biomass. The performance is one of the important issues for the development and commercialisation of fuel cell stacks. LÄS MER

  3. 3. Antivirulent and antibiofilm salicylidene acylhydrazide complexes in solution and at interfaces

    Detta är en avhandling från Umeå : Umeå University

    Författare :Shoghik Hakobyan; Madeleine Ramstedt; Jean-Francois Boily; Mikael Elofsson; Marcus Textor; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antivirulent; Antibiofilm; Hydrazones; Gallium; Pseudomonas aeruginosa; Type three secretion system; Equilibrium constant; Chemical equilibrium modelling; Spectrophotometric titration; UV-Vis;

    Sammanfattning : The growing bacterial resistance against antibiotics creates a limitation for using traditional antibiotics and requests development of new approaches for treatment of bacterial infections. Among the bacterial infections that are most difficult to treat, biofilm-associated infections are one of the most hazardous. LÄS MER

  4. 4. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes

    Detta är en avhandling från Stockholm : KTH

    Författare :Hailong Li; Jinyue Yan; Umberto Desideri; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic property; vapour liquid equilibrium; density; equation of state; interaction parameter; CO2 mixtures; evaporative gas turbine; chemical absorption; oxy-fuel combustion; cost evaluation; CO2 capture and storage; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

  5. 5. Zeolite membranes for efficient synthesis of biofuels

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Linda Sandström; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology - Chemical engineering; Teknikvetenskap - Kemiteknik; Chemical Technology; Kemisk teknologi;

    Sammanfattning : The greenhouse effect and the limited fossil oil resources have increased the demand of renewable fuels. Zeolite membranes have potential applications in numerous separation processes, and could be useful in the development of efficient processes for renewable fuel production. LÄS MER
