  • Warming Accelerates the Onset of the Molecular Stress Response and Increases Mortality of Larval Atlantic Cod 
    Oomen, Rebekah Alice; Knutsen, Halvor; Olsen, Esben Moland; Jentoft, Sissel; Stenseth, Nils Christian; Hutchings, Jeffrey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Synopsis Temperature profoundly affects ectotherm physiology. Although differential thermal responses influence fitness, thus driving population dynamics and species distributions, our understanding of the molecular ...
  • Water browning controls adaptation and associated trade-offs in phytoplankton stressed by chemical pollution 
    Rizzuto, Simone; Thrane, Jan-Erik; Baho, Didier Ludovic; Jones, Kevin C.; Zhang, Hao; Hessen, Dag Olav; Nizzetto, Luca; Leu, Eva Susanne (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)
    The acquisition of tolerance to an environmental stressor can result in organisms displaying slower growth after stress release. While well-grounded in the theory, empirical evidence of the trade-off between stress tolerance ...
  • Water Vapor Photoelectrolysis in a Solid-State Photoelectrochemical Cell with TiO2 Nanotubes Loaded with CdS and CdSe Nanoparticles 
    Kang, Xiaolan; Chaperman, Larissa; Galeckas, Augustinas; Ammar, Souad; Mammeri, Fayna; Norby, Truls; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    In this study, polyol-made CdS and CdSe crystalline nanoparticles (NPs) are loaded by impregnation on TiO2 nanotube arrays (TNTAs) for solar-simulated light-driven photoelectrochemical (PEC) water vapor splitting. For the ...
  • Widespread synchrony in phosphorus concentrations in northern lakes linked to winter temperature and summer precipitation 
    Isles, Peter D. F.; Creed, Irena F.; Hessen, Dag Olav; Kortelainen, Pirkko; Paterson, Michael; Pomati, Francesco; Rusak, James A.; Vuorenmaa, Jussi; Bergström, Ann-Kristin (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract In recent years, unexplained declines in lake total phosphorus (TP) concentrations have been observed at northern latitudes (> 42°N latitude) where most of the world's lakes are found. We compiled data from 389 ...
  • 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 vacancy and oxygen interstitial in ZnO revealed by sequential annealing and electron irradiation 
    Knutsen, Knut Erik; Galeckas, Augustinas; Zubiaga, Asier; Tuomisto, Filip; Farlow, Gary C.; Svensson, Bengt Gunnar; Kuznetsov, Andrej (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    By combining results from positron annihilation and photoluminescence spectroscopy with data from Hall effect measurements, the characteristic deep level emission centered at ∼1.75 eV and exhibiting an activation energy ...
  • Zinc-Vacancy–Donor Complex: A Crucial Compensating Acceptor in ZnO 
    Stehr, J. E.; Johansen, Klaus Magnus H; Bjørheim, Tor Svendsen; Vines, Lasse; Svensson, Bengt Gunnar; Chen, W. M.; Buyanova, I. A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    The aluminum–zinc-vacancy (AlZn−VZn) complex is identified as one of the dominant defects in Al-containing n-type ZnO after electron irradiation at room temperature with energies above 0.8 MeV. The complex is energetically ...
  • 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 ...
  • Zoobooth: A portable, open-source and affordable approach for repeated size measurements of live individual zooplankton 
    Broch, Catharina; Heuschele, Jan David (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Repeated size measurements of individual animals are valuable data for many research questions, but it is often hard to obtain without causing stress or damage to the animal. We developed a video-based approach called ...
  • 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 ...
