  • Crystallinity of silicon nanoparticles: Direct influence on the electrochemical performance of lithium ion battery anodes 
    Ulvestad, Asbjørn; Reksten, Anita; Andersen, Hanne Flåten; Almeida Carvalho, Patricia; Jensen, Ingvild Julie Thue; Nagell, Marius Uv; Mæhlen, Jan Petter; Kirkengen, Martin; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    The use of silicon (Si) in the form of nanoparticles is one of the most promising routes for boosting the capacity of modern Li‐ion batteries. Many parameters influence the performance of Si making the comparison of materials ...
  • Morphology engineering of silicon nanoparticles for better performance in Li-ion battery anodes 
    Lai, Samson Yuxiu; Mæhlen, Jan Petter; Preston, Thomas; Skare, Marte Orderud; Nagell, Marius Uv; Ulvestad, Asbjørn; Lemordant, Daniel; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Amorphous silicon nanoparticles were synthesized through pyrolysis of silane gas at temperatures ranging from 575 to 675 °C. According to the used temperature and silane concentration, two distinct types of particles can ...
  • Structural and magnetic aspects of La4(Co1-xNix)3O10+δ (0 ≤ x ≤ 1) 
    Nagell, Marius Uv; Kumar, Susmit; Sørby, Magnus Helgerud; Fjellvåg, Helmer; Sjåstad, Anja Olafsen (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
    The Ruddlesden–Popper (RP3) type oxides, La4Co3O10+δ and La4Ni3O10+δ, form a complete solid solution. Powder X-ray and neutron diffraction data show that La4(Co1−xNix)3O10+δ is isostructural to the monoclinic La4Co3O10+δ ...
