Donor impurity states and related terahertz range nonlinear optical response in GaN cylindrical quantum wires: Effects of external electric and magnetic fields
(American Institute of Physics Inc., 2014)We report a study on the optical absorption coefficient associated to hydrogenic impurity interstate transitions in zinc-blende GaN quantum wires of cylindrical shape taking into account the effects of externally applied ... -
Topological analysis of tetraphosphorus oxides (P4O6+n (n = 0–4))
(2013)Quantum chemical calculations were used to analyze the chemical bonding and the reactivity of phosphorus oxides (P4O6+n (n=-4)). The chemical bonding was studied using topological analysis such as atoms in molecules (AIM), ... -
Connection between the Hadamard and matrix products with an application to matrix-variate Birnbaum-Saunders distributions
(2012)In this paper, we establish a connection between the Hadamard product and the usual matrix multiplication. In addition, we study some new properties of the Hadamard product and explore the inverse problem associated with ... -
Phosphorus recovery through struvite precipitation from wastewater: effect of the competitive ions

AuN films - Structure and chemical binding
(John Wiley and Sons Ltd, 2015)AuN films were produced on 304 stainless steel using an arc-pulsed - assisted plasma physical vapor deposition system. The deposition was performed using an Au target in a nitrogen atmosphere at different pressures. The ... -
An orbital and electron density analysis of weak interactions in ethanol-water, methanol-water, ethanol and methanol small clusters
(2012)A computational study of (ethanol)n-water, n = 1 to 5 heteroclusters was carried out employing the B3LYP/6-31+G(d) approach. The molecular (MO) and atomic (AO) orbital analysis and the topological study of the electron ... -
Hydrostatic pressure effects on the donor impurity‐related photoionization cross‐section in cylindrical‐shaped GaAs/GaAlAs quantum well wires
(2004)Using a variational method the binding energy has been calculated for a shallow donor impurity and the donor‐related photoionization cross‐section in 1D and 0D GaAs low‐dimensional systems. The dependence on the binding ... -
A family of formulae for pi
(2012)A simple circle method for constructing rational points and tangents with straightedge and compass is introduced; taking the limit, this leads to a family of N formulae for π. The whole process is based on the derivation ... -
