    • Species-Dependent Nanostructured Diatom-SiO2 Anodes: A Sustainable Option for Optimizing Electrode Performance 

      Thangaian, Kesavan; Hua, Weicheng; Aga, Jon Tobias; Nylund, Inger-Emma; Nilsson, Simon; Ericson, Tove; Hahlin, Maria; Svensson, Ann Mari; Blanco, Maria Valeria (Journal article; Peer reviewed, 2024)
      SiO2 structures show great promise for increasing the energy density of anodes for next-generation lithium-ion batteries (LIBs). However, high control of the area, porosity, and morphology of SiO2 particles is critical to ...

    • STEM-EDS of Inception Sites of Vented Trees in a HV XLPE Subsea Cable 

      Hårberg, Sofie Brandtzæg; Nylund, Inger-Emma; Einarsrud, Mari-Ann; Vullum, Per Erik; Lesaint, Cedric Michel; Hvidsten, Sverre (Chapter, 2023)
      High voltage XLPE cable cores have been subjected to wet ageing following the recommendations in CIGRE TB 722. The electrical ageing was performed at 500 Hz and 10 kV/mm. Vented water trees were detected initiating and ...

    • The Structure, Morphology, and Complex Permittivity of Epoxy Nanodielectrics with in Situ Synthesized Surface-Functionalized SiO2 

      Adnan, Mohammed Mostafa; Nylund, Inger-Emma; Jaworski, Aleksander; Hvidsten, Sverre; Ese, Marit-Helen Glomm; Glaum, Julia; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2021)
      Epoxy nanocomposites have demonstrated promising properties for high-voltage insulation applications. An in situ approach to the synthesis of epoxy-SiO2 nanocomposites was employed, where surface-functionalized SiO2 (up ...

    • Structures and Role of the Intermediate Phases on the Crystallization of BaTiO3 from an Aqueous Synthesis Route 

      Bakken, Kristine; Pedersen, Viviann Hole; Blichfeld, Anders Bank; Nylund, Inger-Emma; Tominaka, Satoshi; Ohara, Koji; Grande, Tor; Einarsrud, Mari-Ann (Peer reviewed; Journal article, 2021)
      Carbonate formation is a prevailing challenge in synthesis of BaTiO3, especially through wet chemical synthesis routes. In this work, we report the phase evolution during thermal annealing of an aqueous BaTiO3 precursor ...

    • Tailoring preferential orientation in BaTiO3-based thin films from aqueous chemical solution deposition 

      Bakken, Kristine; Blichfeld, Anders Bank; Nylund, Inger-Emma; Chernyshov, Dmitry; Glaum, Julia; Grande, Tor; Einarsrud, Mari-Ann (Journal article, 2021)
      Ferroelectric properties of thin films can be enhanced by crystallographic texture. In this work, we report on how heat treatment of films can be designed to tailor the degree of preferential orientation in BaTiO3-based ...

    • Transmission electron microscopy of ferroic materials 

      Nylund, Inger-Emma (Doctoral theses at NTNU;2022:109, Doctoral thesis, 2022)
      Materials science has the last few decades been advancing by an increasing insight in structure and local chemical composition at the sub-nanometre scale. In this context, the transmission electron microscope (TEM) has ...
