Electric field gradients of transition metal complexes: Basis setuncontraction and scalar relativistic effects
Ragnar Bjornsson, Michael B�hl
Research Highlights " A reliable DFT protocol is validated for EFGs of 3d transition metalcomplexes. " Large uncontracted basis sets are necessary on the metal, but a nonrelativistictreatment is sufficient. " Because smaller basis sets can be employed on the ligand atoms,the protocol can be applied to larger complexes.
Effect of multiplicative noise on the self-induced aggregationkinetics of Brownian particles
Monoj Kumar Sen, Somrita Ray, Alendu Baura,Bidhan Chandra Bag
Research Highlights " Aggregation kinetics is different for (a) additive and (b) multiplicativenoise driven cases. " Two turning points appear in the variation of structure factor withnoise strength for case (b). " A maximum appears in the variation of structure factor (SF)with noise strength for case (a). " SF passes through a maximum with increase of noisecorrelation time in case of (b). " SF increases monotonically as a function of noisecorrelation time in case of (a).
