  • Accelerated material development for laser powder-bed fusion using the arc melting process 
    Reiersen, Magnus; Gunnæs, Anette Eleonora; S. Azar, Amin; Diplas, Spyridon; Du, Qiang; M'hamdi, Mohammed (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Metal additive manufacturing has in recent years gained an increasing amount of attention, especially the subgroup of laser powder-bed fusion and aluminium alloys. However, established alloys are designed for casting and ...
  • Controlling the Electrical Properties of Reactively Sputtered High Entropy Alloy CrFeNiCoCu Films 
    Mayandi, Jeyanthinath; Finstad, Terje Gunnar; Stange, Marit Synnøve Sæverud; Vasquez, Geraldo Cristian; Sunding, Martin Fleissner; Løvvik, Ole Martin; Diplas, Spyridon; Almeida Carvalho, Patricia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Oxide-containing films were made by reactively sputtering a high-entropy alloy target of CrFeCoNiCu. We report on a wide range of changes to the electrical properties made by different heat treatments in oxidizing and ...
  • Galvanic Deposition of Pt Nanoparticles on Black TiO2 Nanotubes for Hydrogen Evolving Cathodes 
    Touni, Aikaterini; Liu, Xin; Kang, Xiaolan; Almeida Carvalho, Patricia; Diplas, Spyridon; Both, Kevin Gregor; Sotiropoulos, Sotiris; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    A galvanic deposition method for the in-situ formation of Pt nanoparticles (NPs) on top and inner surfaces of high-aspect-ratio black TiO2-nanotube electrodes (bTNTs) for true utilization of their total surface area 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 (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 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 ...
  • Reference data set of volcanic ash physicochemical and optical properties 
    Vogel, Andreas; Diplas, Spyridon; Durant, Adam; Azar, Amin Shahrestani; Sunding, Martin Fleissner; Rose, William I.; Sytchkova, Anna Krasilnikova; Bonadonna, Costanza; Krüger, Kirstin; Stohl, Andreas (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
  • Roadmap for additive manufacturing of HAYNES® 282® superalloy by laser beam powder bed fusion (PBF-LB) technology 
    Otto, Robert; Brøtan, Vegard; Carvalho, Patricia A.; Reiersen, Magnus; Graff, Joachim Seland; Sunding, Martin Fleissner; Åsebø Berg, Olav; Diplas, Spyridon; Azar, Amin Shahrestani (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Although various alloy systems have been explored for additive manufacturing (AM) during the past decade, introducing a new alloy remains a challenging task. Most of the materials require iterative builds, for investigating ...
  • Thin films made by reactive sputtering of high entropy alloy FeCoNiCuGe: Optical, electrical and structural properties 
    Mayandi, Jeyanthinath; Finstad, Terje Gunnar; Dahl, Øyvind; Ponniah, Vajeeston; Schrade, Matthias; Løvvik, Ole Martin; Diplas, Spyridon; Almeida Carvalho, Patricia (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    Films were reactively sputtered from a high entropy alloy (HEA) FeCoNiCuGe target in an Ar/O2 plasma. The case of zero O2 gas flow yielded HEA films of FeCoNiCuGe. These as-deposited HEA films have a face centered cubic ...
  • 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 ...
