Rare earth element distribution in the ne Atlantic: Evidence for benthic sources, longevity of the seawater signal, and biogeochemical cycling
(Journal article; Peer reviewed, 2018)Seawater rare earth element (REE) concentrations are increasingly applied to reconstruct water mass histories by exploiting relative changes in the distinctive normalised patterns. However, the mechanisms by which water ... -
Rare event simulations reveal subtle key steps in aqueous silicate condensation
(Journal article; Peer reviewed, 2017)A replica exchange transition interface sampling (RETIS) study combined with Born-Oppenheimer molecular dynamics (BOMD) is used to investigate the dynamics, thermodynamics and mechanism of the early stages of the silicate ... -
Rational design of mixed solvent and porous graphene-supported spinel oxide electrodes for high-rate and long cycle-life Mg batteries
(Peer reviewed; Journal article, 2019)The development of Mg batteries based on the interfacial charge storage mechanism, where the capacity originates from capacitive processes and the solvent-related interfacial reactions, could efficiently circumvent the ... -
Rational design of protein inhibitors using molecular modelling and multivariate analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:59, Doctoral thesis, 2004)Cancer cells utilise signalling cascades involving protein kinases for their growth and survival. Hence, design of protein inhibitors that block the function of these signalling proteins is interesting for the development ... -
