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). ...

Key Role of the Local Hydrophobicity in the East Patch of Plastocyanins on Their Thermal Stability and Redox Properties
(American Chemical Society, 2018)
Understanding the molecular basis of the thermal stability and functionality of redox proteins has important practical applications. Here, we show a distinct thermal dependence of the spectroscopic and electrochemical ...

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., ...

Light-Induced Control of the Spin Distribution on Cu⁻Dithiolene Complexes: A Correlated Ab Initio Study
(MDPI, 2019)
Metal dithiolene complexes-M(dmit)₂-are key building blocks for magnetic, conducting, and optical molecular materials, with singular electronic structures resulting from the mixing of the metal and dmit ligand orbitals. ...

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 ...

A Theoretical Study on the Inclusion of Fe, Cu, and Zn in Illite Clays
(Hindawi, 2019)
The inclusion of Fe, Cu, and Zn in (1, 0, 0), (0, 0.5, 0), and (0.5, 0.5, 0.5) sites of an illite with the KAl2Si4O12H2 structure has been studied. For the inclusion of the metals, their common oxidation states were chosen, ...

Effect of Basicity on the Hydrolysis of the Bi(III) Aqua Ion in Solution: An Ab Initio Molecular Dynamics Study
(American Chemical Society, 2018-02-22)
Hydrolysis of the Bi(III) aqua ion under a range of solution conditions has been studied by means of ab initio molecular dynamics simulations. While the Bi(III) aqua ion is stable in pure water, there is an increasing ...
