Rhombohedral R3c to orthorhombic Pnma phase transition induced by Y-doping in BiFeO3
(IOP Publishing, 2018-06)
In this work we study, by means of ab initio calculations, the structural, electronic and magnetic properties of Y-doped BiFeO3 compounds. We determine that there is a morphotropic phase boundary at an yttrium concentration ...
Structural mosaicity and electrical properties of pyrolitic SnO2:F thin films
(Elsevier Science SA, 2013-03)
In this work we present structural and electrical properties of SnO2:F thin films deposited on glass substrate by the spray pyrolysis technique. The precursors of SnO2:F were synthesized by a sol?gel method, starting from ...
Primeros desarrollos de un dispositivo fotovoltaico para su utilización como sensor de radiación UV
(Asociación Argentina de Energía Solar, 2016-10)
El Departamento de Energía Solar (DES) de la Comisión Nacional de Energía Atómica (CNEA) viene trabajando en el desarrollo y fabricación de sensores de radiación solar desde la década del 90 y son utilizados tanto para ...
Elaboration and characterization of the electrodeposited phosphates masses doped with various ions on stainless steel
(Virtual Institute of Physics, 2014-06)
The present paper is focused on elaboration of phosphate masses with good molar ratios on SS 316L, with fluoride, Zn2+ and Cu2+ as dopant ions, using an electrochemical procedure and also the attempt to select the best ...
Relative Stability of Near-Surface Oxygen Vacancies at the CeO2(111) Surface upon Zirconium Doping
(American Chemical Society, 2019-12)
The effects of Zr doping on the stability of the CeO2(111) surface as a function of the dopant concentration and distribution, as well as on the relative stability of surface and subsurface oxygen vacancies, were studied ...
Influence of A-site magnesium doping on structural and electrical properties of BaZr0.1Ti0.9O3 ceramics
(Springer, 2018-12)
The effects of the replacement of Ba2+ by off-center Mg2+ ions on the structural and electrical properties of BaZr0.1Ti0.9O3 ceramics were investigated. We show that the use of magnesium as A-site dopant favors the formation ...
A first-principles study of pristine and Al-doped activated carbon interacting with 5-Fluorouracil anticancer drug
(Springer, 2018-09-19)
The adsorption of the 5-Fluorouracil (5-FU) molecule on the pristine and Al-doped activated carbon (AC) was investigated by using the Vienna Ab-initio Simulation Package. It is found that the 5-FU molecule is only weakly ...
Simulation of 500 MeV neutrons by using NaCl doped Water Cherenkov detector
(Elsevier, 2020-05)
In this work we show the capabilities of a water Cherenkov detector (WCD) to detect high energy neutrons. We present the simulation of the response of a doped WCD to 500 MeV monochromatic neutrons using Geant4. To do this, ...
Comparative study of ZnO thin films doped with transition metals (Cu and Co) for methylene blue photodegradation under visible irradiation
(MDPI AG, 2020-05)
We synthesized and characterized both Co-doped ZnO (ZnO:Co) and Cu-doped ZnO (ZnO:Cu) thin films. The catalysts’ synthesis was carried out by the sol–gel method while the doctor blade technique was used for thin film ...
A first-principles modeling of Ni interactions on CeO2-ZrO 2 mixed oxide solid solutions
(American Chemical Society, 2011-04)
We performed DFT+U quantum period calculations to study the characteristics of Ni interactions on/in CeO2-ZrO2 mixed oxide solid solutions. We analyzed the energetics of Ni adsorption and insertion on/in different surface ...
