• Alumina scale composition and growth rate in distribution pipes 

      Haugland, Ingrid Bokn; Kjos, Ole Sigmund; Røyset, Arne Karstein; Vullum, Per Erik; Aarhaug, Thor Anders; Halstensen, Maths (The Minerals, Metals & Materials Series;2367-1181, Peer reviewed; Journal article, 2019)
      Scaling in distribution pipes for secondary alumina is a major issue in aluminium smelters. The scale is formed inside the distribution pipes, and gradually reduces the cross section that is available for alumina transport. ...
    • Coloured Building Integrated Photovoltaics: Influence on Energy Efficiency 

      Røyset, Arne Karstein; Kolås, Tore; Jelle, Bjørn Petter (Journal article; Peer reviewed, 2019)
      Building integrated photovoltaics (BIPV) has attracted increased commercial interest in recent years due to a growing focus on efficient utilization of land area and local renewable energy generation. Aesthetic aspects ...
    • Cool coatings with high near infrared transmittance for coil coated aluminium 

      Kolås, Tore; Røyset, Arne Karstein; Grandcolas, Mathieu; ten Cate, Mattijs; Lacau, Anica (Journal article; Peer reviewed, 2019)
      The temperature of a surface that is exposed to sunlight is influenced by the solar reflectance and the infrared emittance of the surface. A coating that reduces the surface temperature is often referred to as a cool ...
    • Design of a micro-optical low coherent interferometer array for the characterisation of MEMS and MOEMS 

      Gastinger, Kay; Haugholt, Karl Henrik; Røyset, Arne Karstein (Chapter, 2009)
      The EU-project SMARTIEHS (SMART InspEction system for High Speed and multi-functional testing of MEMS and MOEMS) develops a new inspection concept for MEMS and MOEMS (M(O)EMS) testing on the wafer level. The inspection ...
    • Pixelization approach for façade integrated coloured photovoltaics-with architectural proposals in city context of Trondheim, Norway 

      Xiang, Changying; Matusiak, Barbara Szybinska; Røyset, Arne Karstein; Kolås, Tore (Peer reviewed; Journal article, 2021)
      Façade integrated photovoltaics (FIPV) is an emerging and essential way to utilize solar energy in built environment. However, there is limited architectural study of FIPV, especially addressing the topic of colour ...
    • Valence charge distribution in homogenous silicon-aluminium thin-films 

      Thøgersen, Annett; Jensen, Ingvild Julie Thue; Stange, Marit Synnøve Sæverud; Røyset, Arne Karstein; Løvvik, Ole Martin; Ulyashin, Alexander; Diplas, Spyridon (Peer reviewed; Journal article, 2018)
      Homogenous aSi1−xAlxHy alloyed thin films, made by magnetron sputtering, has been found to exhibit tunable band gap and dielectric constant depending on their composition. The optical properties of alloys are largely defined ...
