Comparison of standard DFT and Hubbard-DFT methods in structural and electronic properties of TiO 2 polymorphs and H-titanate ultrathin sheets for DSSC application
(Elsevier Science, 2018-01-15)
The structural and electronic properties of several TiO 2 polymorphs and hydrogen titanate surfaces are modeled and studied by density functional theory (DFT). By implementing the Hubbard parameter “U” in our calculations ...
A computational study (DFT, MP2, and GIAO-DFT) of substituent effects on protonation regioselectivity in β,β-disubstituted vinyldiazonium cations: Formation of highly delocalized carbenium/diazonium dications
(John Wiley & Sons Ltd, 2010-02)
Protonation reactions were studied by quantum-chemical theoretical methods (DFT and MP2) for a series of β,β-disubstituted vinyldiazonium cations (1+-14+), bearing stabilizing electron-releasing groups (H3CO-, (H3C)2N-, ...
Thermoanalytical, spectroscopic and DFT studies of heavy trivalent lanthanides and yttrium(III) with Oxamate as Ligand
(2017-07-01)
Solid-state LnL3·nH2O complexes, where Ln stands for trivalent lanthanides (Tb to Lu) or yttrium(III) and L is oxamate (NH2COCO2-), have been synthesized. The characterization of the complexes was performed by using elemental ...

Nuclear Fukui functions from nonintegral electron number calculations
(2007)
Numerical results for the nuclear Fukui function (NFF) based on a nonintegral number of electrons methodology (NIEM) are reported for a series of simple diatomic molecules. A comparison with those obtained from other ...
Quantum chemistry simulation of the electronic properties in [Au(NH3)(2)]NO3 and [Au(NCH)(2)][AuCl4] extended unsupported complexes
(Taylor & Francis, 2020)
The understanding of closed-shell interactions has become of tremendous relevance in the ever-growing field of supramolecular chemistry. Here, we present a theoretical study in which we characterised the intermolecular ...
