  1. 1. Oxidation kinetics of nickel particles

    Författare :Richard Karmhag; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Oxidation; kinetics; nickel; particles; UFP; solar absorber; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Nanoparticles have an immense surface to volume ratio. This is a key factor to the new properties of some materials made up of such particles. The oxide layer formed on all materials will have a large influence on the behaviour of these materials. The layer isadvantageous in some cases but causes problems in other. LÄS MER

  3. 2. Kinetics for oxidation of CRUD model compounds

    Författare :Maryam Abili Nejad; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactor chemistry; radiolysis; oxidation; kinetics; crud; metal oxide;

    Sammanfattning : The formation of CRUD (Chalk River Unidentified Deposit) inwater-cooled nuclear reactors constitute a severe problem. Thestability of CRUD under reactor conditions (high flux ofionizing radition, high temperature and pressure) must be knownin order to minimize the problem. LÄS MER

  4. 3. Initial Oxidation Kinetics of Al(111): A Monte Carlo Study

    Författare :Dogan Ergun Oner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide nucleation and growth; dissociative adsorption; metal oxidation; Monte Carlo simulations; Al 111 ; kinetics; aluminium; surface oxidation;

    Sammanfattning : Almost all metals around us have a thin oxide layer on top of the bulk metal underneath. Often this oxide film protects the metal against further oxidation, or corrosion. Examples are the oxide film that makes stainless steel "stain-less" or the ones on titanium and aluminium alloys, which are very corrosion resistant. LÄS MER

  5. 4. Characterization of Carbon Oxidation Kinetics for Particulate Matter Reduction Technologies

    Författare :Carolin Ohlson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heterogeneous catalysis; Carbon – catalyst interaction; Soot oxidation; Particulate filter; Carbon oxidation; Global kinetics; Regeneration; Particulate matter oxidation; DPF;

    Sammanfattning : Transport related emissions of particulate matter (PM) represent a significant health risk and are therefore strictly regulated in most developed countries. An efficient technique to reduce emissions of combustion particles is to capture the particles in a filter, which must be subsequently regenerated by oxidation of the carbonaceous fraction of the PM.

  7. 5. High Temperature Corrosion of FeCrAl Alloys: The influence of water vapour and alkali salt

    Författare :Niklas Israelsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-oxidation; FeCrAl; kinetics; high temperature corrosion; KCl; water vapour; alumina; oxidation;

    Sammanfattning : The corrosive environment in biomass- and waste-fired boilers has been known for several years. The traditionally used FeCr and FeNiCr steels show limited performance in the aggressive environment that contains more H2O and alkali salts than traditional fuel. LÄS MER
