    • Lithiation of Silicon Carbide. 

      Acharya, Sushil (Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-06-15)
      Nowadays, different material like: lithium, silicon, germanium and tin are under investigation as possible anode materials for Lithium ion batteries (LIBs.) The function of anode in LIB is to accommodate the lithium ion ...

    • Charged FENE-P non-newtonian fluid model 

      Orioma, Charles (Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-06-15)

    • Atomic scattering factors and atomic cross-sections in x-ray crystallography 

      Nes, Ioana Andreea (Masteroppgave/UIS-TN-IMF/2018;, Master thesis, 2018-06-15)
      Crystallographers as well as other scientists and engineers need reliable sets of physical data. Focus is here set upon the x-ray attenuation coefficients (the atomic photoeffect cross-section, and the incoherent (Compton) ...

    • Effect of additives, ball milling and isotopic exchange in porous magnesium borohydride 

      Heere, Michael; Zavorotynska, Olena; Deledda, Stefano; Sørby, Magnus Helgerud; Book, David; Steriotis, Theodore; Hauback, Bjørn (Journal article; Peer reviewed, 2018-08)
      Magnesium borohydride (Mg(BH4)2) is a promising material for solid state hydrogen storage. However, the predicted reversible hydrogen sorption properties at moderate temperatures have not been reached due to sluggish ...

    • Value regions of univalent self-maps with two boundary fixed points 

      Gumenyuk, Pavel; Prokhorov, Dmitri (Journal article; Peer reviewed, 2018)
      In this paper we find the exact value region V(z0,T) of the point evaluation functional f → f(z0) over the class of all holomorphic injective self-maps f : D → D of the unit disk D having a boundary regular fixed point at ...

    • Anomalous low-temperature thermodynamics of QCD in strong magnetic fields 

      Brauner, Tomas; Kadam, Saurabh (Journal article; Peer reviewed, 2017-11)
      The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ...

    • Universal spacetimes in four dimensions 

      Hervik, Sigbjørn; Pravda, Vojtech; Pravdova, Alena (Journal article; Peer reviewed, 2017-10)
      Universal spacetimes are exact solutions to all higher-order theories of gravity. We study these spacetimes in four dimensions and provide necessary and sufficient conditions for universality for all Petrov types except ...

    • Exact Solutions of the Field Equations for Empty Space in the Nash Gravitational Theory 

      Aadne, Matthew Terje; Grøn, Øyvind (Journal article; Peer reviewed, 2017-02)
      John Nash has proposed a new theory of gravity. We define a Nash-tensor equal to the curvature tensor appearing in the Nash field equations for empty space, and calculate its components for two cases: 1. A static, spherically ...

    • On a class of integrable systems of Monge-Ampère type 

      Doubrov, Boris; Ferapontov, Eugene V.; Kruglikov, Boris; Novikov, Vladimir (Journal article; Peer reviewed, 2017-06)
      We investigate a class of multi-dimensional two-component systems of Monge-Ampère type that can be viewed as generalisations of heavenly type equations appearing in a self-dual Ricci-flat geometry. Based on the Jordan-Kronecker ...

    • Scattering amplitudes of massive Nambu-Goldstone bosons 

      Brauner, Tomas; Jakobsen, Martin Fonnum (Journal article; Peer reviewed, 2018-01)
      Massive Nambu-Goldstone (mNG) bosons are quasiparticles the gap of which is determined exactly by symmetry. They appear whenever a symmetry is broken spontaneously in the ground state of a quantum many-body system and at ...
