Reaction Method

The Tl2-xTexBa2CaCu2O8-δ (Tl-2212) high temperature superconductors with x = 0.0-0.5 have been prepared by the standard solid-state reaction method. The precursor powder were sintered at 900°C for 24 h with several grindings and heating. The powder were then pressed into pellets and heated at 910°C in oxygen flow for 4 min followed by furnace cooling. The electrical resistance versus temperature dependence measurements showed metallic normal state behavior for all samples. Substitution of Te at the Tl-site led to multi-phasic samples. The x = 0.4 sample showed the highestTc zero= 98 K and Tconset= 111K. The Tl-2212 phase increased from 50% for x=0 up to 92% in the x= 0.4 sample.

A Value

ABSTRACTFilms of tin condensed onto 4K pyrex substrates can be driven from “insulating” (i.e. dR/dT < 0) to superconducting behavior by low temperature annealing. Global superconductivity occurs when the normul state sheet resistance, R□, shrinks to a value very near R□ ≡ h/4ea, as in experiments where R□ is changed by increasing the film thickness. When R□ > R□, conduction is decidedly non-ohmic, with R□(T,V) = R□(T) + R1 (T)exp(−m(T)|V|).

Three Dimensional Finite Element

Abstract Recent advances in the development of a general three-dimensional finite element methodology for modeling large deformation steady state behavior of tire structures is presented. The new developments outlined here include the extension of the material modeling capabilities to include viscoelastic materials and a generalization of the formulation of the rolling contact problem to include special nonlinear constraints. These constraints include normal contact load, applied torque, and constant pressure-volume. Several new test problems and examples of tire analysis are presented.

The Relationship

Chapter 1 explores perspectives on world order, including power relationships and the rules that shape state behavior and perceptions of legitimacy. After outlining a brief history of the relationship between Russia and China that ranged from cooperation to military clashes, the chapter details Chinese and Russian perspectives on the contemporary international order as shaped by their histories and current political situation. Chinese and Russian views largely coincide on security issues, the desirability of a more multipolar order, and institutions that would enhance their standing in the world. While the Chinese–Russian partnership has accelerated considerably, particularly since the crisis in Ukraine in 2014, there are still some areas of competition that limit the extent of the relationship.

STABLE hc/e VORTICES IN SUPERCONDUCTORS WITH SPIN-CHARGE SEPARATION

Normal State Properties

A phenomenological model, F, of the superconducting phase of systems with spin-charge separation and antiferromagnetically induced pairing is studied. Above Hc1, magnetic flux can always pierce the superconductor in vortices with flux hc/2e, but regimes are found in which vortices with flux hc/e are preferred. Little-Park and other experiments, which examine periodicities with a varying magnetic field, always observe a period of hc/2e. The low energy properties of a symplectic large-N expansion of a model of the cuprate superconductors are argued to be well described by F. This analysis and some normal state properties of the cuprates suggest that hc/e vortices should be stable at the lowest dopings away from the insulating state at which superconductivity first occurs.
