Experimental and theoretical study of the compound [Pd(dmba)(NCO)(imz)]
(Elsevier B.V., 2007-03-17)
The compound [Pd(dmba)(NCO)(imz)] (dmba = N,N-dimethylbenzilamine; NCO = cyanate; imz = imidazole) was studied through experimental and theoretical methods. The complex was synthesized and characterized by IR and NMR ...
Study of phase transition in (Pb,Ba)TiO(3) thin films
(American Institute of Physics (AIP), 2008-07-01)
Dielectric and Raman scattering experiments were performed on polycrystalline Pb(1-x)Ba(x)TiO(3) thin films (x=0.40 and 0.60) as a function of temperature. The dielectric study on single phase compositions revealed that a ...
Reply to Comment on 'Pb1-xCaxTiO3 solid solution (x=0.0, 0.25, 0.50, and 0.75): A theoretical and experimental approach'
(Amer Physical Soc, 2010-02-01)
Chandra [Phys. Rev. B 77, 017101 (2008)] disagrees with the coexistence of a pseudocubic structure with a long-range tendency for cubic symmetry and tetragonal in a short-range order for the Pb1-xCaxTiO3 (PCT) system ...
Structural and vibrational study of cubic Sb2O3 under high pressure
(Amer Physical Soc, 2012-05-18)
We report an experimental and theoretical study of antimony oxide (Sb2O3) in its cubic phase (senarmontite) under high pressure. X-ray diffraction and Raman scattering measurements up to 18 and 25 GPa, respectively, have ...
Activity and characterization by XPS, HR-TEM, Raman spectroscopy, and BET surface area of CuO/CeO2-TiO2 catalysts
(Amer Chemical Soc, 2001-11-01)
Structural and textural studies of a CuO/TiO2 System modified by cerium oxide were conducted using Raman spectroscopy, transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), and N-2 absorption (BET ...
V(2)O(5)/TiO(2) catalytic xerogels raman and EPR studies
(Springer, 2002-08-01)
Raman spectroscopy and Electron Paramagnetic Resonance (EPR) studies were performed on a series of V(2)O(5)/TiO(2) catalysts prepared by a modified sol-gel method in order to identify the vanadium species. Two species of ...
Surface characterisation of V(2)O(5)/TiO(2) catalytic system
(Wiley-Blackwell, 2001-09-16)
Samples of the V(2)O(5)/TiO(2) system were prepared by the sol-gel method and calcined at different temperatures. Surface species of vanadium, their dispersion, as well as the structural evolution of the system were analysed ...
Superfluido de fermi aprisionado com Variação de Interação Atômica
(Universidade Estadual Paulista (Unesp), 2010-03-01)
Neste trabalho consideramos um gás diluído de átomos de Fermi a baixas temperaturas, com igual numero de átomos de espin para acima (↑) e espin para abaixo (↓) formando um conjunto de N pares de átomos fermiônicos prisioneiros ...
Modal representation of three-phase lines applying two transformation matrices: Evaluation of its eigenvectors
(IEEE, 2006-01-01)
The objective of this paper is to show an alternative representation in time domain of a non-transposed three-phase transmission line decomposed in its exact modes by using two transformation matrices. The first matrix is ...
Time Domain Analyses for Three-phase Lines with Corrected Modal Transformation Matrix
(IEEE, 2012-01-01)
The results presented in this paper are based on a research about the application of approximated transformation matrices for electromagnetic transient analyses and simulations in transmission lines. Initially, it has ...
