    • 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 ...
