    Dynamic impurities in two-dimensional topological-insulator edge states 
    Wozny, Simon; Leijnse, Martin; Erlingsson, Sigurdur I. (2021-11-15)
    Helical edge states of two-dimensional topological insulators show a gap in the density of states (DOS) and suppressed conductance in the presence of ordered magnetic impurities. Here we will consider the dynamical effects on the DOS and transmission ...

    Influence of Phosphorus on Current Efficiency in Aluminum Electrolysis at Different Current Densities 
    Meirbekova, Rauan; Haarberg, Geir Martin; Thonstad, Jomar; Saevarsdottir, Gudrun Arnbjorg (The Electrochemical Society, 2017)
    Many factors may contribute to loss of current efficiency (CE) in aluminum reduction and one of them is a presence of impurities. In this work, the effect of phosphorus on CE is studied in a laboratory cell at different current densities. Due to a ...

    QM/MM calculations reveal a bridging hydroxo group in a vanadium nitrogenase crystal structure 
    Benediktsson, Bardi; Þórhallsson, Albert Þ.; Bjornsson, Ragnar (Royal Society of Chemistry (RSC), 2018)
    A new 1.2 Å crystal structure of vanadium nitrogenase, isolated under turnover conditions, recently revealed a light atom ligand (OH or NH) replacing the bridging S2B sulfide of the FeV cofactor. QM/MM calculations on the new structure now reveal the ...

    Simulation of short pulse photoemission in a microdiode with implications for optimal beam brightness 
    Árnason, Hákon Örn; Torfason, Kristinn; Manolescu, Andrei; Valfells, Ágúst (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Molecular dynamics simulations, with full Coulomb interaction, are used to model short-pulse photoemission from a finite area in a microdiode. We demonstrate three emission regimes, source-limited emission, space-charge-limited emission for short pulses, ...
