Electrical transport across nanometric SrTiO3 and BaTiO3 barriers in conducting/insulator/conducting junctions
(Institute of Physics Publishing, 2018-01-11)
We report the electrical transport properties of conducting/insulator/conducting heterostructures by studying current-voltage IV curves at room temperature. The measurements were obtained on tunnel junctions with different ...
Photoactive layer-by-layer films of cellulose phosphate and titanium dioxide containing phosphotungstic acid
(Elsevier Science, 2013-07)
A versatile layer-by-layer (LbL) procedure for the preparation of highly dispersed, adherent and porous multilayer films of TiO2 nanoparticles (NPs) and phosphotungstic acid (HPW) on a variety of substrates at room temperature ...

Unraveling the photoelectrochemical behavior of Ni-modified ZnO and TiO2 thin films fabricated by RF magnetron sputtering
(Elsevier Science SA, 2021-02)
Zinc oxide (ZnO) and titanium oxide (TiO2) thin films are fabricated by radio frequency magnetron sputtering, which allows fine control of the properties and compositions of semiconductor materials with practical application ...
Physicochemical stability under inert and reductive atmospheres of Li2TiO3 produced from Li2CO3 obtained from Argentinean brines
(Elsevier Science Sa, 2018-05)
Lithium metatitanate (Li2TiO3) is one of the most promising candidates as tritium breeder material in a fusion reactor due to its physical and chemical properties. In this paper, the syntheses of Li2TiO3 by combustion in ...
Elastic, dielectric and electromechanical properties of (Bi0.5Na0.5)TiO3-BaTiO3piezoceramics at the morphotropic phase boundary region
(Elsevier Science Sa, 2016-08)
A systematic study of the functional properties of the (1-x)(Bi0.5Na0.5)TiO3–xBaTiO3(BNT-xBT) piezoceramic system for 0.05 ≤ x ≤ 0.07 is performed. The samples are obtained through the conventional solid-state route. The ...
