An ab initio study of oxygen vacancies and doping process of Nb and Cr atoms on TiO2 (110) surface models
(Wiley-Blackwell, 1997-12-05)
We theoretically investigated how the formation of oxygen vacancies and the addition of niobium and chromium atoms as dopants modify the varistor properties of TiO2. The calculations were carried out at the HF level using ...

Radiative association of Ti and O atoms
(Oxford University Press, 2012-11-01)
Rate coefficients for the radiative association of titanium and oxygen atoms to form the titanium monoxide (TiO) molecule are estimated. The radiative association of Ti(F-3) and O(P-3) atoms is dominated by an approach ...

Measurement of oxygen atom diffusion in Nb and Ta by anelastic spectroscopy
(ABM, ABC, ABPol, 2005-09-01)
Impurity interstitial atoms present in metals with BCC structure can diffuse in the metallic matrix by jumps to energetically equivalent crystallographic sites. Anelastic spectroscopy (internal friction) is based on the ...

Oxygen Diffusion in an Nb-Ta Alloy Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2011-01-01)
When metals that present bcc crystalline structure receive the addition of interstitial atoms as oxygen, nitrogen, hydrogen and carbon, they undergo significant changes in their physical properties because they are able ...
Structural study of copper oxide supported on a ceria-modified titania catalyst system
(Kluwer Academic/plenum Publ, 2002-01-01)
A structural study of CuO supported on a CeO2-TiO2 system was undertaken using X-ray diffraction (XRD) and X-ray absorption spectroscopy (XAS) techniques. The results of XRD revealed the presence of only two phases, TiO2 ...
