Rapid, comprehensive screening of ionic liquids towards sustainable applications
(Peer reviewed; Journal article, 2019)A computational screening strategy applied to 8 million synthetically diverse ionic liquids, demonstrates its value for sustainable solvent design. In contrast to previous studies which have largely focused on single ... -
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 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 ... -
