Equations that described the thermodynamic properties of the NaBr+H2O system were obtained from a fit to experimental results for this system. The experimental results included in the fit spanned the range of temperature of approximately 260 to 623 K and the range of pressure from the vapor pressure of the solution to…
The phosphor has been investigated for its application to vacuum fluorescent displays (VFDs) utilizing low‐voltage cathodoluminescence. It is expected that this oxide phosphor does not cause damage to filaments in VFD's, while it is a serious problem for conventional sulfide phosphors. This phosphor shows blue lumines…
We have constructed the metallicity distribution of a sample of 372 kinematically selected halo stars, most having spectroscopically determined abundances, drawn from our southern subdwarf study and the northern program of Laird et al. [AJ, 95, 1843 (l988a); 96, 1908 (l988b)]. We find that the metallicity distribution…
The dynamic response of the electrons at the surface of simple metals, like Na, K and Cs, to an external time varying field is discussed in this paper. Of special interest are the normal modes at a surface, defined theoretically by the poles in the reflection function. The surface plasmon is the best known normal mode…

Molecular mechanics calculations, based on a force field derived from a previously published normal coordinate analysis for NiOEP (1) and the X-ray structure of NiOEP? triclinic form, have been used to predict the structures of NiTPP (2), NiP (3), and several recently synthesized nickel porphyrins which bear alkyl or…
This is a review paper on the history of ferroelectric thin films, current practices in their fabrication, characteristics of interest which relate to their use, and the application of these films to memory and electrooptic devices.

This paper describes a light-scattering study of the glass transition in nonaqueous suspensions of sterically stabilized colloidal spheres. The observed phase behavior, fluid, crystal, and glass, is consistent with an essentially hard-sphere interaction between the particles. Metastable fluid states were obtained upon…

We have measured the cathodoluminescence spectra of microwave plasma-assisted chemical-vapor deposited (CVD) polycrystalline diamond films at 77 K over the spectral range of 2300–8000 Å. Annealing studies of these spectra have been carried out at 500, 800, 1000, 1200, and 1350 °C. Rich spectra are observed. Many of th…

We use the local density approximation to density functional theory to re-examine the well-known ‘theoretical strength’ of metals. This is done by calculating ideal twin stress in five b.c.c. transition metals, and in Ir, Cu and Al. This leads us to a first-principles, quantum-mechanical confirmation of the Frenkel mo…
Abstract The successive phase transitions of the polymorphs of CsSnI3 were studied by means of the powder X-ray diffraction and their crystal structures were analyzed at three different temperatures by the Rietveld method.
