    Herein, we report the discovery of a toroidal inorganic cluster of zirconium(IV) oxysulfate of unprecedented size with the formula Zr70(SO4)58(O/OH)146⋅x(H2O) (Zr70), which displays different packing of ring units and thus ...
  • Bianchini, Federico; Fjellvåg, Helmer; Vajeeston, Ponniah (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    Transition metal containing polyanion compounds are effective excellent electrode materials for sodium-ion batteries due to their high intrinsic electrochemical potentials and to the resulting high energy density. Iron ...
  • Gurfinkel, Alexander Jacob; Rikvold, Per Arne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Centrality, which quantifies the importance of individual nodes, is among the most essential concepts in modern network theory. As there are many ways in which a node can be important, many different centrality measures ...

    Spectroscopic identification of defects and impurities is crucial for understanding doping asymmetry issues in ZnO and, therefore, realization of true ZnO-based bipolar devices. Chlorine (Cl) is an amphoteric impurity in ...
  • Zhao, Sen; Agafonov, Oleg; Azab, Abdulrahman; Stokowy, Tomasz; Hovig, Eivind (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Abstract Advances in next-generation sequencing technology have enabled whole genome sequencing (WGS) to be widely used for identification of causal variants in a spectrum of genetic-related disorders, and provided new ...
  • Gurfinkel, Aleks J.; Rikvold, Per Arne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Centrality, which quantifies the “importance” of individual nodes, is among the most essential concepts in modern network theory. Most prominent centrality measures can be expressed as an aggregation of influence flows ...
