Study of ionic surfactants interactions with carboxylated single-walled carbon nanotubes by using ion-selective electrodes
(Elsevier, 2016)
Potentiometric measurements based on the use of ion-selective electrodes have been used to study the interaction (adsorption) of anionic and cationic surfactants with functionalized single-walled carbon nanotubes (SWCNT-COOH). ...

Multi-scale multireference configuration interaction calculations for large systems using localized orbitals: Partition in zones
(American Institute of Physics Publising LLC, 2012)
A new multireference configuration interaction method using localised orbitals is proposed, in which a molecular system is divided into regions of unequal importance. The advantage of dealing with local orbitals, i.e., ...

The role of the magnetic orbitals in the calculation of the magnetic coupling constants from multireference perturbation theory methods
(American Institute of Physics Publising LLC, 2012)
The use of multireference perturbation theory (MRPT) for the calculation of the magnetic coupling in binuclear complexes has shown to give poor results if applied on a minimal active space complete active space self-consistent ...
