Published in 2020 at "Computational and Theoretical Chemistry"

DOI: 10.1016/j.comptc.2019.112700

Abstract: Abstract The gas phase proton affinity (PA) and basicity (GB) of a series of extended π-systems, possessing carbonyl as the most basic sites, were calculated using the DFT-B3LYP theoretical method. The backbone of the polycyclic… read more here.

Published in 2018 at "Journal of chemical theory and computation"

DOI: 10.1021/acs.jctc.8b00793

Abstract: At zero temperature, coupled cluster theories are widely used to predict total energies, ground state expectation values, and even excited states for molecules and extended systems. However, for systems with a small band gap, such… read more here.

Published in 2018 at "ACS Omega"

DOI: 10.1021/acsomega.8b01339

Abstract: Stacking interactions have been evaluated, employing computational methods, in dimers formed by analogous aliphatic and aromatic species of increasing size. Changes in stability as the systems become larger are mostly controlled by the balance of… read more here.

Published in 2018 at "Chaos"

DOI: 10.1063/1.5023485

Abstract: The space-time representation of high-dimensional dynamical systems that have a well defined characteristic time scale has proven to be very useful to deepen the understanding of such systems and to uncover hidden features in their… read more here.

Published in 2019 at "Physical Review E"

DOI: 10.1103/physreve.100.042217

Abstract: Thermodiffusion or thermophoresis or Soret effect, i.e., mass-transport induced by thermal gradient, has immense application in segregation of species in two or multicomponent gaseous, liquid, or colloidal mixtures. Here, we show that an external thermal… read more here.
