Service-oriented architecture (SOA) development and deployment generally builds on a service view of the world in which a set of services are assembled and reused to quickly adapt to new business needs. This flexibility is seen by many IT organizatio

The crystal structure of NaY (Na54Si138Al54O384) + CFCl3 has been determined at 20 K by Rietveld analysis of powder neutron diffraction data in space group Fdm. The sodium cations were located preferentially in sites II, which are fully-occupied and

The structural characteristics of the perovskite- based ferroelectric Pb(Zn1/3Nb2/3)O3-9%PbTiO3 at the morphotropic phase boundary (MPB) region (x≃0.09) have been analyzed. The analysis is based on the symmetry adapted free energy functions under t

The symmetry was examined using neutron diffraction method on Pb(Zn1/3Nb2/3)O3 -9%PbTiO3 (PZN/9PT) which has a composition at the morphotropic phase boundary (MPB) between Pb(Zn1/3Nb2/3)O3 and PbTiO3. The results were compared with those of other spe

Thin films of oriented Fe and Cr intercalated (NbSe2)x(TiSe2)y superlattices have been synthesized by controlled annealing of elementally modulated reactants. Analytic techniques have been developed to extract the average c-axis structure of the unit

The crystal and magnetic structures of ${\mathrm{CaFeO}}_{3}$ have been determined at 300 and 15 K using synchrotron x-ray and neutron powder-diffraction techniques. At 300 K, ${\mathrm{CaFeO}}_{3}$ adopts the ${\mathrm{GdFeO}}_{3}$ struture, space g

High resolution x-ray powder diffraction measurements on poled PbZr1-xTixO3 (PZT) ceramic samples close to the rhombohedral-tetragonal phase boundary (the so-called morphotropic phase boundary) have shown that for both rhombohedral and tetragonal com

Charge-lattice fluctuations are observed in the layered perovskite manganite LaSr{sub 2}Mn{sub 2}O{sub 7} by Raman spectroscopy at temperatures as high as 340 K, and with decreasing temperature they become static, forming a charge-ordered (CO) phase

Recently a new monoclinic phase in the Pb(Zr1−xTix)O3 ceramic system has been reported by Noheda et al.[1] for a composition of x=0.48. In this work, samples with Ti contents x=0.47 and 0.50, which are both tetragonal below their Curie point, have
