  • Galvanic restructuring of exsolved nanoparticles for plasmonic and electrocatalytic energy conversion 
    Kang, Xiaolan; Reinertsen, Vilde Mari; Both, Kevin Gregor; Galeckas, Augustinas; Aarholt, Thomas; Prytz, Øystein; Norby, Truls; Neagu, Dragos; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    There is a growing need to control and tune nanoparticles (NPs) to increase their stability and effectiveness, especially for photo- and electrochemical energy conversion applications. Exsolved particles are well anchored ...
  • Selective etching of nanostructured a-Si:Al and its effect on porosity, Al gradient and surface oxidation 
    Kjeldstad, Torunn; Thøgersen, Annett; Stange, Marit Synnøve Sæverud; Jensen, Ingvild Julie Thue; Nilsen, Ola; Galeckas, Augustinas; Monakhov, Eduard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Nanoporous amorphous silicon (a-Si) with <5 nm cylindrical pores have been fabricated by phase separation of aluminum (Al) and silicon, forming self-assembled Al nanowires (NWs), followed by subsequent removal of Al by wet ...
  • The Band Gap of BaPrO3 Studied by Optical and Electrical Methods 
    Schrade, Matthias; Magraso, Anna; Galeckas, Augustinas; Finstad, Terje; Norby, Truls (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    We report on measurements of the electrical and optical properties of BaPrO3. The temperature dependences of the electrical conductivity σ and the Seebeck coefficient α of polycrystalline samples were studied over a wide ...
  • Visible Light Driven Photocatalytic Decolorization and Disinfection of Water Employing Reduced TiO2 Nanopowders 
    Kang, Xiaolan; Berberidou, Chrysanthi; Galeckas, Augustinas; Bazioti, Kalliopi; Sagstuen, Einar; Norby, Truls Eivind; Poulios, Ioannis; Chatzitakis, Athanasios Eleftherios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Defect-engineering of TiO2 can have a major impact on its photocatalytic properties for the degradation of persisting and non-biodegradable pollutants. Herein, a series of intrinsic and extrinsic defects are induced by ...
  • Water Vapor Photoelectrolysis in a Solid-State Photoelectrochemical Cell with TiO2 Nanotubes Loaded with CdS and CdSe Nanoparticles 
    Kang, Xiaolan; Chaperman, Larissa; Galeckas, Augustinas; Ammar, Souad; Mammeri, Fayna; Norby, Truls; Chatzitakis, Athanasios (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    In this study, polyol-made CdS and CdSe crystalline nanoparticles (NPs) are loaded by impregnation on TiO2 nanotube arrays (TNTAs) for solar-simulated light-driven photoelectrochemical (PEC) water vapor splitting. For the ...
