Density functional theory study on the structural and electronic properties of low index rutile surfaces for TiO2/SnO2/TiO2 and SnO2/TiO2/SnO2 composite systems
(Amer Chemical Soc, 2008-09-25)
The present study is concerned with the structural and electronic properties of the TiO2/SnO2/TiO2 and SnO2/TiO2/SnO2 composite systems. Periodic quantum mechanical method with density functional theory at the B3LYP level ...
Elastic modulus and hardness of CaTiO3, CaCu3Ti4O12 and CaTiO3/CaCu3Ti4O12 mixture
(Elsevier B.V., 2010-05-31)
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 degrees C for 180 ...

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 ...
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 ...
