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 ...
Computational simulations of morphological transformations by surface structures: The case of rutile TiO2 phase
(2017-07-01)
Computational simulations based on periodic density functional theory have been carried out to investigate the control of crystal morphology by accurate values of surface energies by Wulff theorem. This method can be used ...

Simulation of heme using DFT + U: a step toward accurate spin-state energetics
(American Chemical Society, 2007-06-05)
We investigate the DFT + U approach as a viable solution to describe the low-lying states of ligated and unligated iron heme complexes. Besides their central role in organometallic chemistry, these compounds represent a ...
Simulated mechanical properties of finite-size graphene nanoribbons
(IOP Publishing, 2020-01)
There are many simulation studies of mechanical properties of graphene nanoribbons (GNR), but there is a lack of agreement regarding elastic and plastic behavior. In this paper we aim to analyze mechanical properties of ...
Conductance through glycine in a graphene nanogap
(Springer, 2018-06-08)
We report theoretical analysis of charge transport process through a single glycine molecule utilizing graphene nanogaps. Density functional theory and non-equilibrium Green's function method are employed to investigate ...
Percolation of hydrogen atoms adsorbed on Cu(100) surfaces: DFT, Monte Carlo and finite size scaling techniques
(Pergamon-Elsevier Science Ltd, 2019-03-15)
Hydrogen adsorption on Cu(100) surfaces was studied taking into account percolation problem. In order to represent the real system, DFT calculations were perfomed to calculate adsorption energies of a hydrogen atom in ...
Computer simulation of reversible electrochemical catalyst promoter dosing
(Pergamon-Elsevier Science Ltd, 2010-12)
Grand Canonical Monte Carlo simulations were used to study the growth of a Na layer onto a O-p(2 × 2)-Pt(1 1 1) surface. At the beginning of the deposition, the film presents a disordered structure which becomes progressively ...
