    • Activity and segregation behavior of Pd75%Ag25%(1 1 1) during CO oxidation – An in situ NAP-XPS investigation 

      Svenum, Ingeborg-Helene; Strømsheim, Marie D.; Knudsen, Jan; Venvik, Hilde Johnsen (Peer reviewed; Journal article, 2022)
      The surface reactivity during CO oxidation over Pd(1 1 1) and Pd75%Ag25%(1 1 1) single crystals has been investigated using near ambient pressure X-ray photoelectron spectroscopy (NAP-XPS) under excess oxygen conditions ...

    • Effects of CO2 cover gas and yttrium additions on the oxidation of AlMg alloys 

      Smith, Nicholas Albert; Gleeson, Brian; wissam, saidi; Kvithyld, Anne; Tranell, Gabriella (Light Metals;2019, Chapter; Peer reviewed, 2019)
      AlMg alloys are known to suffer from problematic oxidation that can result in significant dross formation and loss of Mg from the melt. Historically, beryllium has been used to minimize the oxidation as it forms a protective ...

    • Fume Formation from Oxidation of Liquid SiMn Alloy 

      Ma, Yan; Kero, Ida; Tranell, Gabriella (Peer reviewed; Journal article, 2017)
      Thermally generated fumes from the production of manganese ferroalloys are mostly composed of metallic oxides generated due to reaction between high-temperature molten metal and ambient oxygen in the air. In the current ...

    • Important Aspects Regarding the Chemical Stability of Aqueous Amine Solvents for CO2 Capture 

      Vevelstad, Solrun Johanne; Buvik, Vanja; Knuutila, Hanna K; Grimstvedt, Andreas Magnar; Silva, Eirik Falck da (Peer reviewed; Journal article, 2022)
      The chemical stability of aqueous amines is an essential property to study before new amines are introduced in pilot plants, to reduce risks related to the operation, cost and environment. There are no standard methods for ...

    • Mechanism behind the Inhibiting Effect of CO2 on the Oxidation of Al−Mg Alloys 

      Smith, Nicholas Albert; Gleeson, Brian; wissam, saidi; Kvithyld, Anne; Tranell, Gabriella (Peer reviewed; Journal article, 2018)
      Al–Mg alloys are known to suffer from problematic oxidation during melting, refining, and casting. The use of a CO2/air cover gas is known to minimize this oxidation; however, a mechanistic understanding of the beneficial ...

    • XPS Examination of the Oxide-Metal interface of an Al-Mg Alloy Containing Beryllium 

      Smith, Nicholas; Kvithyld, Anne; Tranell, Gabriella (The Minerals, Metals & Materials Series;2367-1181, Chapter, 2018)
      The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ...
