Abstract The Couchman equation for miscible blends has been extended. The new semiempirical equation, w 1 ln ( T g / T g1 ) + kw 2 ln ( T g / T g2 ) = 0, is simple to use and flexible enough to provide an adequate description of T g variation with composition for miscible, semimiscible, and immiscible blends. The equa…

Abstract The crystal structure of botallackite, Cu 2 (OH) 3 Cl, monoclinic, a = 5.717(1), b = 6.126(1), c = 5.636(1)Å, β = 93.07(1)°, V = 197.06(5)Å 3 , space group P 2 1 / m , Z = 1, has been refined to an R index of 3.8% for 350 observed (4 σ ) reflections, measured with Mo- Kα X-radiation on an automatic four-circl…

Electron microscopical studies of diatoms growing on the skin of cetaceans and assigned to the genus Cocconeis have been carried out with material from both hemispheres. The results of this study have led to establishment of two new genera, Bennettella and Epipellis. Bennettella includes the former Cocconeis ceticola…

Crack growth data are presented for soda‐lime glass in various chemical environments. It is shown that the same environments which govern crack growth rates in vitreous silica also do so in soda‐lime glass. The slopes and positions of the crack growth curves in soda‐lime glass are shown to differ from those in vitreou…
We show that physically realistic solutions for nonlinear TM waves guided by thin dielectric films are obtained in the uniaxial approximation for a dielectric constant proportional to the square of the normal-field component and not of the parallel-field component as assumed previously.
Commercial Y 2 O 3 : Eu phosphors, formulated at constant europium content, exhibit under 254 nm excitation plaque‐brightness variations of up to 10%. Several working models are proposed to explain this variation in emission brightness, and their physical implications on the spectral behavior of the Y 2 O 3 : Eu mater…
Abstract The mineralogy of six profiles from the Median Trough of El Salvador has been investigated. Most of these soils have vertic properties and are developed from Quaternary alluvium. The mineralogical evolution of these soils has been influenced by intermittent additions of a readily soluble source of silica and…
The α-modification of (BEDT-TTF)2 I3 undergoes a metal-to-insulator transition at T = 135 K. Application of hydrostatic pressure shifts the transition temperature to lower values. Above 12 kbar semimetallic behavior is observed, but no superconductivity is detected up to a pressure of 17 kbar and temperatures down to…

Turbulent convection in silicon melts used in the Czochralski crystal‐growth method was found to be effectively suppressed by applying a transverse magnetic field over 2000G. When turbulent convection is suppressed, it was found that the oxygen concentration in the resulting silicon crystals could be precisely control…
Voids in the aluminum metallization of integrated circuits can be created under certain device fabrication conditions. The formation and characteristics of these defects have been studied in detail. It is found that the density and size of the metal voids have a strong functional dependence on the compressive stress o…
Abstract Hydrogenation of polybutadienes with from 8 to nearly 100% vinyl content was used to prepare a series of model copolymers of ethylene and butene‐1 with uniform microstructures and narrow molecular weight distributions. They range from readily crystallizable to completely amorphous, depending on the frequency…
A fully quantum mechanical model of the particle–surface sticking process is developed, and calculations are performed for a variety of atoms, molecules and solids of relevance to the interstellar medium. The sticking coefficient is a sensitive function of the nature of the particle–surface interaction and the lattice…
