    • 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 ...

    • Effects of metal dusting relevant exposures of alloy 601 surfaces on carbon formation and oxide development 

      Guo, Xiaoyang; Vanhaecke, Estelle Marie M.; Vullum, Per Erik; Ma, Jianyu; Panditha Vidana, Daham Sanjaya Gunawardana; Walmsley, John; Chen, De; Venvik, Hilde Johnsen (Peer reviewed; Journal article, 2020)
      Ni and Fe are excellent catalysts for carbon formation, and industrial alloys are therefore susceptible to metal dusting corrosion; a costly issue in e.g. synthesis gas manufacture. The objective of this work is to better ...

    • Holistic Processing of Sawdust to Enable Sustainable Hybrid Li-Ion Capacitors 

      Guo, Xiaoyang; van de Kleut, Dick; Zhang, Jia; Chen, Chaofan; Wang, Xuehang; Zheng, Tianye; Boles, Steven Tyler (Peer reviewed; Journal article, 2024)
      Activated carbon has long been recognized as a promising electrode material for energy storage devices. The extraordinarily high specific area makes it challenging to replace in supercapacitors since electrical double-layer ...

    • 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 ...

    • Inhibition of metal dusting corrosion on Fe-based alloy by combined near surface severe plastic deformation (NS-SPD) and thermochemical treatment 

      Guo, Xiaoyang; Vullum, Per Erik; Venvik, Hilde Johnsen (Peer reviewed; Journal article, 2021)
      Combined NS-SPD and thermochemical treatment has been used to improve the metal dusting corrosion resistance of Incoloy 800. After testing under infinite carbon activity for 20−100 h, carbon was not found in the NS-SPD ...

    • 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 ...

    • Unlocking Room Temperature Formation of Li-Rich Phases in Aluminum Anodes for Li-ion Batteries 

      Zheng, Tianye; Zhang, Jia; Guo, Xiaoyang; Jin, Wei; Boles, Steven Tyler (Journal article; Peer reviewed, 2024)
      Aluminum (Al) has been an attractive anode candidate for lithium-ion batteries (LIBs) since the 1970s. While the formation of β-LiAl is considered the origin of the Li storage capability in Al anodes, multiple Li-Al phases ...
