  • Zeolite morphology and catalyst performance: Conversion of methanol to hydrocarbons over offretite 
    Lukaszuk, Katarzyna Anna; Rojo-Gama, Daniel; Øien-Ødegaard, Sigurd; Lazzarini, Andrea; Berlier, Gloria; Bordiga, Silvia; Lillerud, Karl Petter; Olsbye, Unni; Beato, Pablo; Lundegaard, Lars Fahl; Svelle, Stian (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The synthesis, characterization and catalytic performance of offretite with four distinct crystal morphologies (oval, hexagonal, broccoli-like, and spherical) are presented. As a member of the ABC-6 family of zeolite ...
  • Zeolite surface methoxy groups as key intermediates in the stepwise conversion of methane to methanol 
    Dyballa, Michael Martin; Thorshaug, Knut; Pappas, Dimitrios; Borfecchia, Elisa; Kvande, Karoline; Bordiga, Silvia; Berlier, Gloria; Lazzarini, Andrea; Olsbye, Unni; Beato, Pablo; Svelle, Stian; Arstad, Bjørnar (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    This contribution clarifies the overoxidation-preventing key step in the methane-to-methanol (MTM) conversion over copper mordenite zeolites. We followed the methane-to-methanol conversion over copper mordenite zeolites ...
  • Zinc schiff base complexes derived from 2,2'-diaminobiphenyls: Solution behavior and reactivity towards nitrogen bases 
    Hylland, Knut Tormodssønn; Øien-Ødegaard, Sigurd; Heyn, Richard H.; Tilset, Mats (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Zn complexes of Schiff base ligands derived from 2,2'‐diaminobiphenyls and salicylaldehyde derivatives were synthesized and characterized by NMR and single‐crystal X‐ray diffraction analysis. The detailed NMR studies suggest ...
  • Zircon and quartz inclusions in garnet used for complementary Raman thermobarometry: application to the Holsnøy eclogite, Bergen Arcs, Western Norway 
    Zhong, Xin; Andersen, Niels Højmark; Dabrowski, Marcin; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2019)
    Mineral inclusions are common and have been widely used to investigate complex geological history. When a rock undergoes cooling and decompression after the entrapment of an inclusion into a host mineral, residual pressure ...
  • Zn Redistribution and Volatility in ZnZrOx Catalysts for CO2 Hydrogenation 
    Redekop, Evgeniy; Cordero-Lanzac, Tomás; Salusso, Davide; Pokle, Anuj; Øien-Ødegaard, Sigurd; Sunding, Martin Fleissner; Diplas, Spyridon; Negri, Chiara; Borfecchia, Elisa; Bordiga, Silvia; Olsbye, Unni (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    ZnO–ZrO2 mixed oxide (ZnZrOx) catalysts are widely studied as selective catalysts for CO2 hydrogenation into methanol at high-temperature conditions (300–350 °C) that are preferred for the subsequent in situ zeolite-catalyzed ...
  • Zn vacancy formation, Zn evaporation and decomposition of ZnSb at elevated temperatures: Influence on the microstructure and the electrical properties 
    Song, Xin; Schrade, Matthias; Maso Carcases, Nahum; Finstad, Terje (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)
    The influence of annealing on the microstructure and electrical properties of undoped polycrystalline ZnSb samples has been investigated by different experimental techniques. In situ XRD in an argon at- mosphere showed ...
  • The α and γ plasma modes in plasma-enhanced atomic layer deposition with O2-N2 capacitive discharges 
    Napari, M; Tarvainen, O; Kinnunen, S; Arstila, K; Julin, J; Fjellvåg, Øystein Slagtern; Weibye, Kristian; Nilsen, Ola; Sajavaara, T (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    Two distinguishable plasma modes in the O2–N2 radio frequency capacitively coupled plasma (CCP) used in remote plasma-enhanced atomic layer deposition (PEALD) were observed. Optical emission spectroscopy and spectra ...
  • σ-Cyclopropyl to π-Allyl Rearrangement at AuIII 
    Holmsen, Marte Sofie Martinsen; Vesseur, David; García-Rodeja, Yago; Miqueu, Karinne; Bourissou, Didier (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract The possibility for Au III σ‐cyclopropyl complexes to undergo ring‐opening and give π‐allyl complexes was interrogated. The transformation was first evidenced within (P,C)‐cyclometalated complexes, it occurs within ...
