Sonia Spence Jet Plane Mp3 Download

I first heard of Sonya Spence music at as a young boy in 1983, when music players were a thing for the rich, in Ghana . My uncle travelled from Nigeria to ghana and brought a system with sonya spence cassette, which at dawn while were still sleeping, he slotted in on a low volume. Unconsciously i was soaking iinto my spirit her music and i bece a fan of Sonya. Her voice and articulation were awsome. May she rest well.

The way she sang the song created a vivid imagination of the scene- a sad, sorrowful but upbeat lover, embarking on an inevitable journey, on a jet plane, that would take her away for a while but with the hope of a return that would culminate in an engagement.

Does haptic information on a plane surface alter the appearance of the visual illusion?

During the last decade, a lot of theoretical and experimental work has been devoted to the study of the magnetic properties of SrCu2(BO3)2. This compound crystallizes in a tetragonal structure where layers of CuBO3 alternate with planes of Sr atoms along the [001] direction. Due to this unusual structure where Cu2+ atoms are arranged in the layers to form a network of orthogonal dimers, SrCu2(BO3)2 appears as the first realization of a 2D Heisenberg model known as the Shastry-Sutherland model and exhibits a number of unique features such as a spin gapped behavior, unusual magnetic excitations or magnetization plateaux. Solid-state magnetism is always intimately related to the underlying electronic structure of solids. Electron energy loss spectroscopy and in particular, energy loss near edge fine structure (ELNES) is one of the most powerful solid state spectroscopies allowing the investigation of the electronic structure of materials. When combined with ab initio band structure calculations, this technique provides an efficient way to determine the energy position and the character of the unoccupied states in a solid.In this work, we present an experimental and theoretical study of the O-K edge recorded in SrCu2(BO3)2. In a first part, we will show that under specific experimental conditions of illumination and collection, the conventional TEM can be used to determine the spatial orientation of the electronic states in such an anisotropic material. In a second part, we will show how a careful analysis of the O-K edge fine structure can be used to estimate the on site Cu-3d Coulomb and exchange interactions (U). These interactions not only play a crucial role in the electronic structure of this compound, leading to the creation of a correlation gap, but also scale to superexchange coupling constants appearing in the Shastry-Sutherland model. Therefore, electron energy loss spectroscopy can provide relevant and quantitative information when studying the magnetic properties of strongly correlated systems such as cuprates compounds.

Cerium-zirconium mixed oxides have recently been used as common promoting components of the three way catalysts (TWC) employed for the elimination of toxic exhaust gases in automobiles[1]. The achievement of a high oxygen storage capacity (OSC), related to the particular ability of the CeO2-ZrO2 oxides to undergo rapid reduction/oxidation cycles, has been shown to be of major relevance for the enhancement of the performance in their application as catalysts in TWC and other fields. Therefore, a precise understanding of the redox behaviour is essential to establish optimum synthesis procedures for these materials.In this work, high-resolution electron microscopy, high-angle annular dark field images, electron tomography and density functional theory calculations show the occurrence of significant structural and surface modifications in a nanoparticle Ce-Zr oxide sample upon high-temperature reduction with hydrogen followed by mild oxidation (SR-MO treatment).[2,3] Structural changes are related with the occurrence of a disorder-order transition in the cationic sublattice of the ceria-zirconia mixed oxides resulting in an ordered arrangement of Ce4+ and Zr4+ cations. Fourier transforms obtained from HREM images show the appearance, after the SR-MO treatment, of superstructure spots characteristic of a pyrochlore-related structure.Surface modifications involve a transition from roundedlike crystallites to well-faceted oxide particles with a significant increase of the presence of {111} faces in the SR-MO treated oxide observed in the HREM images. HAADF-STEM tomography reveals that these faceted crystallites have a shape very close to that of an octahedron, in agreement with the observed increase of {111} facets. Furthermore, the close inspection of high-resolution HAADF-STEM images shows an alternating intensity sequence in intensity profiles recorded along lines normal to the {111} fringes, suggesting an alternation of Ce-rich and Zr-rich planes along that direction, being in all the analyzed HAADF images the uppermost surface plane a Zr-rich {111} plane. This particular surface termination of the mixed oxide nanocrystals seems to be at the basis of an enhanced H2 dissociation capacity and, therefore in the increase of OSC observed after the application of SR-MO treatments.Let us also emphasize how TEM-STEM techniques have provided unique information about both the bulk and the surface of oxide nanocrystals that allows us rationalizing their macroscopic redox behaviour. 1 J.

The development of spherical aberration (Cs) imaging correctors for medium-voltage transmission electron microscopes offers new opportunities for atomic-scale investigation of materials. One advantage of Cs-corrected HRTEM over conventional HRTEM is that the delocalization of the image contrast can be reduced below the typical separation of atomic columns in low-index crystal projections by tuning the spherical aberration to small values. This is particularly important for the investigation of crystal defects and interfaces where the translation symmetry of the perfect crystal is broken and a range of spatial frequencies contribute to the image contrast. We have investigated the misfit layer compound (PbS)1.14NbS2 which consists of an alternating stacking of two atomic sheets of cubic PbS and a sandwich layer of hexagonal NbS2. Two structural features make the HRTEM investigation of this compound particularly interesting and challenging. First, the two layers are incommensurate in one in-plane direction, i.e. different periodicities meet at the interfaces. Secondly, light atomic columns (S) and heavy atomic columns (mixed Pb/S) occur on opposite sides of each interface. We demonstrate that direct imaging of the complete projected crystal structure including the atomic columns at the interfaces becomes possible by applying Cs-corrected HRTEM in a Titan 80-300 instrument under imaging conditions with negative Cs values (NCSI-contrast). Evaluation of such images allows us to locally study structural phenomena, like layer distortion and stacking disorder, which so far could only be investigated by spatially averaging X-ray diffraction methods. An even more precise investigation of atomic column positions is achieved when we combine Cs-corrected HRTEM with exit-wave reconstruction from defocus series.M.
