  • Solbu, Kasper (Doctoral thesis / Doktoravhandling, 2011)
    During the last decade, there has been an increased concern of impact to human health from exposure to lubricants and organophosphates (OPs) for workers in the aviation industry. In spite of this concern, neither methods ...
  • Ellingsen, Josef Gert Åsheim; Venkatachalapathy, Vishnukanthan; Azarov, Alexander; Nilsen, Ola; Kuznetsov, Andrej (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Aluminium zinc oxide (AZO) is a promising transparent conductive oxide this is difficult to fabricate by metal-organic chemical vapour deposition (MOCVD) because of prereactions between the precursors for Al and oxygen. ...
  • Løken, Andreas; Saeed, Sarmad Waheed; Norderhaug, Marit; Liu, Xin; Bjørheim, Tor Svendsen (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    In the present contribution, we assess the efficiency of the alkali metals (Na, K, Rb and Cs) as A-site acceptor dopants in proton conducting BaZrO3 by first principles calculations. The calculated acceptor–proton complexes ...
  • Xu, Kaiqi (Master thesis / Masteroppgave, 2016)
    The combination of solar energy and water splitting hydrogen production results in a feasible, prospective energy conversion and storage process—photoelectrochemical (PEC) water splitting. In this work, an all-solid-state ...
