ISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A two-dimensional thermodynamic model was developed to account for the observed difficulty in the fabrication of epitaxial Pb(Zr,Ti)O3 (PZT) thin films in which tetragonal and rhombohedral phases coexist. The thermodynamic formalism based on the Landau–Devonshire's phenomenological theory predicts the enhanced thermodynamic stability of the tetragonal-phase field under a two-dimensional compressive stress. We have experimentally proved this prediction by fabricating an epitaxially oriented tetragonal PZT thin film on MgO substrate with the target composition corresponding to the bulk morphotropic phase boundary (MPB). © 1998 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1999Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: A phenomenological thermodynamic model has been developed to account for the effects of the film thickness on various properties of ferroelectric thin films. To this end, we have suitably incorporated a position-dependent stress distribution function into the elastic Gibbs function. Various physical properties can be predicted as a function of the film thickness using this modified thermodynamic formalism. A comparison of the theoretical predictions with experimental values of the average strain and the para-ferro transition temperature indicates that the tensile stress caused by the cubic-tetragonal displacive phase transition dominates over the compressive thermal stress in the epitaxially oriented tetragonal Pb(Zr, Ti)O3 thin films. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Effects of hydrostatic pressure on various ferroelectric phase transitions in Pb(Zr, Ti)O3 (PZT) have been investigated using the thermodynamic formalism based on the Landau–Devonshire phenomenological theory. For these purposes, the rotostrictive coefficient related to the coupling between the tilting of oxygen octahedron and the stress was evaluated first. We have then simulated three-dimensional phase diagrams of the PZT system using composition, stress and temperature as the three independent thermodynamic variables. It has been shown that, with increasing tensile hydrostatic pressure, the para–ferro transition temperature increases but the transition temperature between the two ferroelectric rhombohedral phases (FR(HT)–FR(LT)) decreases, and the morphotropic phase boundary moves slightly toward the tetragonal-phase field. Contrary to these, opposite tendencies are predicted under a compressive stress. The thermodynamic computation of ferroelectric properties in the vicinity of the FR(HT)–FR(LT) phase transition further suggests that a first-order phase transition gradually becomes a continuous second-order transition with increasing tensile stress. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1084Keywords: Key words: Stomach – Neoplasm – Helical CTSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract. Glomus tumor occurs only rarely in the stomach. This benign intramural mass is located most frequently in the distal half of the stomach. We experienced two cases of glomus tumor of the stomach which were examined with helical CT and were confirmed pathologically. Both tumors were well-marginated solitary lesions, located in the gastric antrum. On the early-phase helical CT, an intact overlying mucosa was demonstrated in both cases, and both tumors showed a dense homogeneous contrast enhancement, which persisted to the delayed phase.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1077-3118Source: AIP Digital ArchiveTopics: PhysicsNotes: The magnetic microstructure in a Co/Pt multilayer has been imaged by magnetic force microscopy employing a novel tip structure. Magnetic tips have been fabricated by evaporating a thin film onto a single facet of the pyramidal tip of a silicon nitride cantilever. Nanolithographically defined elements have been used to simulate the micromagnetic structure of the tip and have been investigated by the Lorentz mode of electron microscopy. We demonstrate that stray fields from the Co/Pt multilayer can be sensed by the tip producing images of the magnetic microstructure with a fine structure on a scale of 30–40 nm. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The electrical properties of sheets of short carbon fibres in resin, glass-fibre and wood-pulp materials have been investigated. For carbon fibre in wood-pulp, a conductor-to-insulator transition was observed at 3 wt % (0.6 vol %) carbon fibre above which conductivity varied linearly with weight fraction. This result is interpreted in terms of a percolation threshold in a system of high aspect ratio. The data agree well with previous measurements on carbon-fibre in polymer composites, and satisfactorily with two-dimensional Monte Carlo calculations. At high concentrations of carbon fibre in all materials, the in-plane resistivity was found to be strongly time-dependent, the fractional change being proportional to Int. A theoretical model is presented which assumes a continuous increase in the number of interconnecting pathways as fibres physically move together under electrostatic attractive forces. Thermal activation over a continous spectrum of energy barriers leads to logarithmic time dependence as observed experimentally. Studies of the effect of external compression support the model for the time dependence.Type of Medium: Electronic ResourceURL:
