    • Chemical Stability and Characterization of Degradation Products of Blends of 1-(2-Hydroxyethyl)pyrrolidine and 3-Amino-1-propanol 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Francois, Maxime; Knuutila, Hanna K; Haugen, Geir; Wiig, Merete; Vernstad, Kai (Peer reviewed; Journal article, 2022)
      Aqueous amine solvents are used to capture CO2 from various flue gas sources. In this work, the chemical stability of a blend of 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The ...

    • A comparative biodistribution study of polymeric and lipid-based nanoparticles 

      Åslund, Andreas; Vandebriel, Rob J.; Caputo, Fanny; de Jong, Wim H.; Delmaar, Christiaan; Hyldbakk, Astrid; Rustique, Emilie; Schmid, Ruth Baumberger; Snipstad, Sofie; Texier, Isabelle; Vernstad, Kai; Borgos, Sven Even F. (Peer reviewed; Journal article, 2022)
      Biodistribution of nanoencapsulated bioactive compounds is primarily determined by the size, shape, chemical composition and surface properties of the encapsulating nanoparticle, and, thus, less dependent on the physicochemical ...

    • Comparison of different solvents from the solvent degradation rig With real samples 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Haugen, Geir; Kupfer, Rene; Brown, Nathan; Einbu, Aslak; Vernstad, Kai; Zahlsen, Kolbjørn (Journal article; Peer reviewed, 2017)

    • Degradation and emission results of amine plant operations from MEA testing at the CO2 technology centre Mongstad 

      Morken, Anne Kolstad; Pedersen, Steinar; Kleppe, Eirik Romslo; Wisthaler, Armin; Vernstad, Kai; Ullestad, Øyvind; Flø, Nina Enaasen; Faramarzi, Leila; Hamborg, Espen Steinseth (Peer reviewed; Journal article, 2017)
      In 2015, the CO2 Technology Centre Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine ...

    • Evaluation of Results from SDR Campaigns and Pilot Data 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas; Haugen, Geir; Wiig, Merete; Vernstad, Kai (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      For ethanolamine (MEA) many degradation products have been identified and quantified, and the formation of these compounds at different process conditions should be verified. This short paper shows that lab scale experiments, ...

    • Exploration of degradation chemistry by Advanced analytical methodology 

      Grimstvedt, Andreas Magnar; Zahlsen, Kolbjørn; Vevelstad, Solrun Johanne; Vernstad, Kai; Holten, Torunn; Brunsvik, Anders (Journal article; Peer reviewed, 2017)

    • Optimization of FK-506 production in Streptomyces tsukubaensis by modulation of Crp-mediated regulation 

      Schulz, Susann; Sletta, Håvard; Degnes, Kristin Fløgstad; Krysenko, Sergii; Williams, Alicia; Olsen, Silje Malene; Vernstad, Kai; Mitulski, Agnieszka; Wohlleben, Wolfgang (Peer reviewed; Journal article, 2023)
      FK-506 is a potent immunosuppressive macrocyclic polyketide with growing pharmaceutical interest, produced by Streptomyces tsukubaensis. However, due to low levels synthesized by the wild-type strain, biotechnological ...
