Adnan, Mohammed Mostafa; Tveten, Erlend Grytli; Glaum, Julia; Ese, Marit-Helen Glomm; Hvidsten, Sverre; Glomm, Wilhelm; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2018)Epoxy nanocomposites, with inorganic oxide nanoparticles as filler, can exhibit novel property combinations, such as enhanced mechanical strength, higher thermal conductivity, increased dielectric breakdown strength, and ... -
Hot corrosion of Gd2Zr2O7, Gd2Zr2O7/YbSZ, YSZ+Gd2Zr2O7/YbSZ, and YSZ thermal barrier coatings exposed to Na2SO4+V2O5.
Tabeshfar, Mohadese; Salehi, Mehdi; Dini, Ghasem; Dahl, Paul Inge; Einarsrud, Mari-Ann; Wiik, Kjell (Peer reviewed; Journal article, 2020)Gd2Zr2O7 ceramic is considered as a potential candidate for thermal barrier coatings. Here we present hot corrosion behavior of single layer Gd2Zr2O7 (GZO), Gd2Zr2O7 + 50 wt% YbSZ (GZO/YbSZ), YSZ and double-layer ... -
Microstructural and compositional optimization of La0.5Ba0.5CoO3−δ—BaZr1−zYzO3−δ (z=0, 0.05 and 0.1) nanocomposite cathodes for protonic ceramic fuel cells
Rioja-Monllor, Laura; Bernuy-Lopez, Carlos; Fontaine, Marie-Laure; Grande, Tor; Einarsrud, Mari-Ann (Journal article; Peer reviewed, 2019)Cathodes are one of the key components of protonic ceramic fuel cells (PCFCs) requiring further development to enhance the performance of PCFCs. This encompasses the optimization of material compositions and microstructures, ... -
Modified Pechini Synthesis of Oxide Powders and Thin Films
Sunde, Tor Olav Løveng; Grande, Tor; Einarsrud, Mari-Ann (Chapter, 2016)The modified Pechini method has become one of the most popular synthesis methods for complex oxide materials due to its simplicity and versatility. The method can be applied to synthesize nanocrystalline powders, bulk ... -
