An improved AMBER force field for alpha,alpha-dialkylated peptides: intrinsic and solvent-induced conformational preferences of model systems
(Royal Soc Chemistry, Cambridge, 2013)
alpha,alpha-Dialkylated amino acid residues have acquired considerable importance as effective means for introducing backbone conformation constraints in synthetic peptides. The prototype of such a class of residues, namely ...
in/out Isomerism of cyclophanes: a theoretical account of 2,6,15-trithia-[3(4,10)][7]metacyclophane and [3(4,10)][7]metacyclophane as well as their halogen substituted analogues
(Royal Soc Chemistry, Cambridge, 2017)
A detailed theoretical investigation of cyclophanes with a divergent set of methods ranging from molecular mechanics through semiempirical to ab initio is presented. Cyclophanes have attracted interest over the years due ...

Extension of the AMBER force field to cyclic alpha,alpha dialkylated peptides
(Royal Soc Chemistry, Cambridge, 2012)
The popular biomolecular AMBER (ff99SB) force field (FF) has been extended with new parameters for the simulations of peptides containing alpha, alpha dialkylated residues with cyclic side chains. Together with the recent ...
Computational study of the spin-state energies and UV-Vis spectra of bis(1,4,7-triazacyclononane) complexes of some first-row transition metal cations
(Royal Soc Chemistry, Cambridge, 2013)
We report here computed spin-state energies and UV-Vis spectra for several transition metal complexes with a triazacyclononane ligand. Our results show that the spin ground-state is correctly obtained with either OPBE or ...
General treatment of the multimode Jahn-Teller effect: study of fullerene cations
(Royal Soc Chemistry, Cambridge, 2013)
A general model for the analysis of the Adiabatic Potential Energy Surfaces (APES) of the molecules that are subject to the multimode Jahn-Teller effect is presented. The method utilizes the information obtained by DFT ...

A density functional study of the spin state energetics of polypyrazolylborato complexes of first-row transition metals
(Royal Soc Chemistry, Cambridge, 2014)
Density Functional Theory (DFT) was used to analyse and explain spin state energetics of first-row transition metals (Mn-II, Fe-II, Co-II; Cr-III, Mn-III, Fe-III, Co-III; Mn-IV) in polypyrazolylborato complexes. We explored ...
Density functional theory modeling of C-Au chemical bond formation in gold implanted polyethylene
(Royal Soc Chemistry, Cambridge, 2017)
We have studied processes of gold ion implantation in polyethylene (PE) by theoretical chemistry methods. Car-Parrinello molecular dynamics (CPMD) simulations of collisions and following chemical kinetics considerations ...
