Stabilization of charged substitutional ions in tetragonal zirconia

Autor: Pablo Hugo Gargano, Laura Kniznik, Gustavo Emilio Ramirez Caballero, Gerardo Hector Rubiolo, Mariano Forti, Samuel Cotes, Paula Regina Alonso

Publikováno v: Materials Today: Proceedings. 51:488-495

The formation of substitutional and interstitial diluted defects of tantalum, niobium and molybdenum in a tetragonal zirconia (T-ZrO2) crystal was studied with Density Functional Theory calculations. Bader charge analysis was used to select the oxida

RESUMEN El uso de los reactores nucleares como fuente de energía se ha extendido y consolidado en la segunda mitad del siglo XX y en los inicios de este siglo XXI. La continuidad de este recurso depende en gran medida de que las plantas nucleares se

First Principles Study of U-Al System Ground State

Autor: Mariano Forti, Laura Kniznik, Paula Regina Alonso, Gerardo Hector Rubiolo, Pablo Hugo Gargano

Publikováno v: Procedia Materials Science. 1:514-519

Formation energies of the binary intermetallic compounds UAln (n = 2, 3, 4) have been evaluated in the frame of the Density Functional Theory (DFT) using a pseudopotentials method implemented in the Vienna Ab-initio Simulation Package (VASP) code wit

Simulation of UAl4 growth in an UAl3/Al diffusion couple

Autor: Paula Regina Alonso, Gerardo Hector Rubiolo, Pablo Hugo Gargano, Laura Kniznik

Publikováno v: Journal of Nuclear Materials. 414:309-315

In this work the growth of the UAl4 phase in an UAl3/Al diffusion couple is treated as a planar moving boundary problem due to diffusion of Al and U atoms in the direction perpendicular to the interface surface. The diffusion problem was carried out

Energetics and electronic structure of UAl4 with point defects

Autor: Laura Kniznik, Pablo Hugo Gargano, Gerardo Hector Rubiolo, Paula Regina Alonso

UAl4 ideal and defect structures were studied within the framework of the Density Functional Theory. The structural and magnetic ordering of UAl4 in paramagnetic, ferromagnetic, and antiferromagnetic states have been investigated, within the collinea

No labeling quantum mechanics of indiscernible particles

Autor: Federico Holik, Laura Kniznik, Décio Krause, Graciela Domenech

Our aim in this paper is to show an example of the formalism we have developed to avoid the label-tensor-product-vector-space-formalism of quantum mechanics when dealing with indistinguishable quanta. States in this new vector space, that we call the
