The present study evaluates the feasibility of partially dealuminated natural mordenite as a catalyst support by studying improvement in its textural properties. This is the first study that reports the dealumination of natural zeolite-based tuffs fr

We consider some applications of nanotechnology to the oil industry worldwide and in particular we discuss some recent applications in Colombia. We consider some potential applications of nanotechnology to the oil industry in Ecuador and succinctly d

The orientation and physical context of the CMT Series of Workshops have always been cross-disciplinary, but with an emphasis placed on the common concerns of theorists applying many-particle concepts in diverse areas of physics. In this spirit, CMT3

We study the Shannon entropy and the Fisher information in a non-Born-Oppenheimer (nBO) regime, where these quantities are constructed from one-particle densities obtained from an exact nBO analytic wave function for a Coulomb-Hooke model of a four-p

In the present work, resorting to linear response theory, we examine the plausibility of postulating Kohn–Sham (KS)-type equations which contain, by definition, an effective hybrid potential made up by some arbitrary mixture of local and non-local

Density functional theory calculations of single-layer models of niobium sulfide catalysts promoted at the S-border by the transition metal atoms V, Cr, Fe, Co, Ni, and also by Cu are performed. Different degrees of promotion as well as of sulfidatio

The von Neumann version of the Copenhagen interpretation of quantum mechanics, QM, is critically examined and contrasted with alternative realist formulations which show that the notions of both an observer and the collapse of the wave function in th

We deal with different representations of the noninteracting kinetic energy functional for the purpose of examining their effect upon the generation of shell structure in atoms. We decompose the noninteracting functional into a Weizsacker term plus a

Within the framework of density functional theory, a study of approximations to the enhancement factor of the non-interacting kinetic energy functional Ts[ρ] has been presented. For this purpose, the model of Liu and Parr (Liu and Parr, Phys Rev A 1

An approximate expression for the Pauli kinetic energy functional T-p is advanced in terms of the Liu-Parr expansion [S. Liu, R.G. Parr, Phys. Rev. A1997, 55, 1792] which involves a power series of the one-electron density. We use this explicit funct
