THE INTERACTION OF ATOMIC OXYGEN WITH SMALL COPPER CLUSTERS: A THEORETICAL APPROACH
(Sociedad Chilena de Química, 2005)
Structural studies in lead germanate glasses: EXAFS and vibrational spectroscopy
The Raman, IR absorption and EXAFS spectra at the Ge K-edge and Pb LIII-edge of eight lead germanate glasses, with general formula xPbO(1-x)GeO2 with x = 0.20, 0.25, 0.33, 0.40, 0.50, 0.53, 0.56 and 0.60, have been measured. ...
Influence of oxygen flow on crystallization and morphology of LiNbO 3 thin films
Polymeric precursor solution (Pechini method) was used to deposit LiNbO 3 thin films by spin-coating on (100) silicon substrates. X-ray diffraction data of thin films showed that the increase of oxygen flow promotes a ...
Oxygen diffusion in superconducting oxides
(Trans Tech Publications Ltd, 2008-01-01)
Since the discovery of high-temperature superconductivity of cuprate oxides, it has been clear that it is strongly affected by the oxygen content, which is also a crucial factor to determine other physical properties of ...
The radiative association of P and O atoms
(Oxford Univ Press, 2016-04-11)
The formation of PO from the radiative association of phosphorus and oxygen atoms has been estimated by accurate quantum chemistry calculations. The radiative association of P and O atoms along the B-2 Sigma(+) potential ...
Bonding of water to copper atom at an almost random interaction
(Revista Mexicana de Física, 2010)
An ab initio study of oxygen vacancies and doping process of Nb and Cr atoms on TiO2 (110) surface models
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 ...
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 ...
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 ...
