• Effects of K adsorption on the CO-induced restructuring of Co(11-20) 

      Strømsheim, Marie Døvre; Svenum, Ingeborg-Helene; Farstad, Mari Helene; Li, Zheshen; Gavrilovic, Ljubisa; Guo, Xiaoyang; Lervold, Stine; Borg, Anne; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2017)
      The location of potassium (K) on Cobalt (Co) and its effect on adsorption and adsorption-induced surface restructuring is important for understanding the deactivation of Co Fischer-Tropsch catalysts and the nature of the ...
    • Inhibiting carbon growth at the initial stage of metal dusting corrosion of high temperature alloys 

      Guo, Xiaoyang (Doctoral theses at NTNU;2020:212, Doctoral thesis, 2020)
      Metal dusting corrosion is a high temperature degradation phenomenon affecting Fe-, Ni- and Co- based alloys when exposed to strongly carburizing gases (carbon activity ac > 1) at elevated temperatures (> 400˚C). The alloy ...
    • Investigation of metal dusting corrosion process over UNS N08800 alloy 

      Guo, Xiaoyang; Panditha Vidana, Daham Sanjaya Gunawardana; Chen, De; Vanhaecke, Estelle Marie M.; Venvik, Hilde Johnsen; Walmsley, John (Journal article; Peer reviewed, 2017)
      Metal dusting corrosion is a catastrophic degradation phenomenon that initiates on metallic surfaces of chemical process equipment at elevated temperature and under carburizing atmospheres. It proceeds by a gradual breakdown ...
    • Near Ambient Pressure XPS Investigation of CO Oxidation Over Pd3Au(100) 

      Strømsheim, Marie Døvre; Knudsen, Jan; Farstad, Mari Helene; Sørvik, Linn Cecilie; Guo, Xiaoyang; Venvik, Hilde Johnsen; Borg, Anne (Journal article; Peer reviewed, 2017)
      The CO oxidation behavior under excess oxygen and near stoichiometric conditions over the surface of Pd3Au(100) has been studied by combining near-ambient pressure X-ray photoelectron spectroscopy and quadrupole mass ...
    • Risk identification of third-party damage on oil and gas pipelines through the Bayesian network 

      Guo, Xiaoyang; Zhang, Laibin; Liang, Wei; Haugen, Stein (Journal article, 2018)
      This paper aims to identify the risks influencing oil and gas (O&G) pipeline safety caused by third-party damage (TPD). After comprehensive literature study, we found that the traditional risk identification of TPD suffers ...
