Co2 Separation in Nanocomposite Membranes by the Addition of Amidine and Lactamide Functionalized POSS® Nanoparticles into a PVA Layer
Guerrero Heredia, Gabriel; Hagg, May-Britt; Simon, Christian; Peters, Thijs; Rival, Nicolas; Denonville, Christelle (Peer reviewed; Journal article, 2018)In this article, we studied two different types of polyhedral oligomeric silsesquioxanes (POSS®) functionalized nanoparticles as additives for nanocomposite membranes for CO2 separation. One with amidine functionalization ... -
Development of novel metal-supported proton ceramic electrolyser cell with thin film BZY15–Ni electrode and BZY15 electrolyte
Stange, Marit Synnøve Sæverud; Stefan, Elena; Denonville, Christelle; Larring, Yngve; Rørvik, Per Martin; Haugsrud, Reidar (Peer reviewed; Journal article, 2017)Metal supports for planar MS-PCEC were manufactured using tape-casting of low-cost ferritic stainless steel. A coating protecting the metal support against oxidation was applied by vacuum infiltration and a buffer layer ... -
Electromechanical and biological evaluations of 0.94Bi0.5Na0.5TiO3–0.06BaTiO3 as a lead-free piezoceramic for implantable bioelectronics
Hall, Thomas A.G.; Theodoridis, Konstantinos; Kechagias, Stylianos; Kohli, Nupur; Denonville, Christelle; Rørvik, Per Martin; Cegla, Frederic; van Arkel, Richard J. (Journal article, 2023)Smart implantable electronic medical devices are being developed to deliver healthcare that is more connected, personalised, and precise.

Factors Limiting the Apparent Hydrogen Flux in Asymmetric Tubular Cercer Membranes Based on La27W3.5Mo1.5O55.5−δ and La0.87Sr0.13CrO3−δ
Li, Zuoan; Polfus, Jonathan Marc; Xing, Wen; Denonville, Christelle; Fontaine, Marie-Laure; Bredesen, Rune (Journal article; Peer reviewed, 2019)Asymmetric tubular ceramic–ceramic (cercer) membranes based on La27W3.5Mo1.5O55.5−δ-La0.87Sr0.13CrO3−δ were fabricated by a two-step firing method making use of water-based extrusion and dip-coating. The performance of the ... -
Hydrogen separation membranes based on dense ceramic composites in the La27W5O55.5–LaCrO3 system
Polfus, Jonathan M.; Xing, Wen; Fontaine, Marie-Laure; Denonville, Christelle; Henriksen, Partow Pakdel; Bredesen, Rune (Peer reviewed; Journal article, 2015)Some compositions of ceramic hydrogen permeable membranes are promising for integration in high temperature processes such as steam methane reforming due to their high chemical stability in large chemical gradients and CO2 ... -
