    • Factors Determining Microporous Material Stability in Water: The Curious Case of SAPO-37 

      Kalantzopoulos, Georgios N.; Lundvall, Fredrik; Thorshaug, Knut; Lind, Anna Maria; Vajeeston, Ponniah; Dovgaliuk, Iurii; Arstad, Bjørnar; Wragg, David; Fjellvåg, Helmer (Peer reviewed; Journal article, 2020)
      Silicoaluminophosphates (SAPOs) are a special class of zeolites that, due to their acidic and shape-selective properties, play a major role in ion exchange and separation processes and in crude oil cracking. SAPO-37 has ...
    • High entropy alloy CrFeNiCoCu sputter deposited films: Structure, electrical properties, and oxidation 

      Mayandi, Jeyanthinath; Schrade, Matthias; Vajeeston, Ponniah; Stange, Marit Synnøve Sæverud; Lind, Anna Maria; Sunding, Martin Fleissner; Deuermeier, Jonas; Fortunato, Elvira; Løvvik, Ole Martin; Ulyashin, Alexander; Diplas, Spyridon; Almeida Carvalho, Patricia; Finstad, Terje Gunnar (Peer reviewed; Journal article, 2022)
      High entropy alloy (HEA) films of CrFeCoNiCu were deposited by sputtering. Their structure was characterized and their electric transport properties were studied by temperature-dependent Hall and Seebeck measurements. The ...
    • In-situ XRD studies of dolomite based CO2 sorbents 

      Arstad, Bjørnar; Lind, Anna Maria; Andreassen, Kari Anne; Pierchala, Joanna; Thorshaug, Knut; Blom, Richard (Peer reviewed; Journal article, 2014)
      Calcined dolomite (a CaOMgO material derivative of the natural mineral dolomite) has the potential as a CO2 sorbent working at high temperatures (500-650 °C) in processes like post combustion carbonate-looping, or in sorbent ...
    • SAPO-37 microporous catalysts: revealing the structural transformations during template removal 

      Kalantzopoulos, Georgios N.; Lundvall, Fredrik; Lind, Anna Maria; Arstad, Bjørnar; Chernyshov, Dmitry; Fjellvåg, Helmer; Wragg, David (Peer reviewed; Journal article, 2017)
      We have studied the structural behavior of SAPO-37 during calcination using simultaneous in situ powder X-ray diffraction (PXRD) and mass spectroscopy (MS) in addition to ex situ thermogravimetric analysis (TGA) and ...
    • Structural changes in SAPO-34 due to hydrothermal treatment. A NMR, XRD, and DRIFTS study 

      Arstad, Bjørnar; Lind, Anna Maria; Cavka, Jasmina Hafizovic; Thorshaug, Knut; Akporiaye, Duncan; Wragg, David; Fjellvåg, Helmer; Grønvold, Arne; Fuglerud, Terje (Peer reviewed; Journal article, 2016)
      When SAPO-34 is used as an industrial MTO catalyst, structural transformations leading to permanent deactivation are inevitable. The performance loss is linked principally to a redistribution of Si in the material, leading ...
    • Studies of Ca-based high temperature sorbents for CO2 capture 

      Arstad, Bjørnar; Spjelkavik, Aud I.; Andreassen, Kari Anne; Lind, Anna Maria; Prostak, Joanna; Blom, Richard (Peer reviewed; Journal article, 2013)
      The natural mineral dolomite has been calcined and impregnated with Ti-, Zr-, Al-nanoparticle suspensions with the aim of improving the cyclic stabilities in high temperature CO2 sorption processes. After impregnation and ...
