Elastic modulus and hardness of CaTiO3, CaCu3Ti4O12 and CaTiO3/CaCu3Ti4O12 mixture
(Elsevier Science, 2010-03-03)
Three ceramic systems, CaTiO3 (CTO), CaCu3Ti4O12 (CCTO) and intermediate nonstoichiometric CaTiO3/CaCu3Ti4O12 mixtures (CTO.CCTO), were investigated and characterized. The ceramics were sintered at 1100 °C for 180 min. The ...
Electrosteric colloidal stabilization for obtaining SrTiO3/TiO2 heterojunction: Microstructural evolution in the interface and photonics properties
(2018-04-01)
Researches on solids heterojunctions has proven to be an important field for technological applications due to synergism achieved by interface phenomena. In this work, we present an understanding of SrTiO3/TiO2 interface ...
Evaluation of Ni0, NiO, and NiS as a Cocatalyst Modifier on TiO2Nanotubes Matrix for the Enhancement of Photoelectrocatalytic Oxidation of Penicillin G
(2021-07-01)
The development of an effective cocatalyst for the modification of TiO2 arrays has become highly desirable for the improvement of their photoelectrocatalytic properties. We investigated the modification of TiO2 with ...
Silver ion release from electrodes of nanotubes of TiO2 impregnated with Ag nanoparticles applied in photoelectrocatalytic disinfection
(Elsevier B.V., 2014-03-15)
Self-organized TiO2 nanotubes arrays electrodes were impregnated with 0-16% of Ag nanoparticles (Ti/TiO2-Ag) using different procedures. The electrodes were characterized by X-ray diffraction (XRD), scanning electron ...
Caracterização das ligas Ni-Ti-Mo, Ni-Ti-Ta e Ni-Ti-Mo-Zr obtidas por moagem de alta energia e prensagem a quente

DFT+U simulation of the Ti4 O7-Ti O2 interface
(2015-02-20)
The formation of conducting channels of Ti4O7 inside TiO2-based memristors is believed to be the origin for the change in electric resistivity of these devices. While the properties of the bulk materials are reasonably ...
CATALYTIC OZONATION OF OXALIC ACID WITH MnO2/TiO2 AND Rh/TiO2

Metal-oxide and oxide-metal interaction effects on thin film oxide. The Ti/TiO2 and TiO2/Ti cases.
(Elsevier Science, 2003-12)
Through Auger electron spectroscopy (AES) and factor analysis (FA), we have studied the effect of metal–metal and metal–oxide interface interactions on the Ti oxide film formation. The passivation of Ti thin film oxidation ...
