The polarized laser-Raman scattering of oriented single crystals of β-AgI has been investigated at 300°, 80°, and 4.2°K. The fundamental optic lattice modes predicted by group theory were observed and assigned on the basis of scattering tensors. Further support for the present assignments of the β-AgI optic lattice mo…
In a copper crystallite containing many hundreds of atoms the static and dynamic behavior of point defects is simulated by means of an electronic computer. This follows the lines of an earlier work by Gibson et al. We have extended their investigation to collisions with subthreshold energies using a new computer progr…
The compound Bi2WO6 has been prepared as a ceramic and in single crystal form. Growth of Bi2WO6 single crystals from the melt by the Czochralski method produced boules as large as 20 mm in diameter by 60 mm long. On cooling to room temperature these boules invariably cracked, yielding for experimental investigations s…
Abstract On the example of transition metal hydrides, the role of interaction between interstitial atoms in the formation of ordered solid solutions and interstitial compound structures has been examined.
After revision, the molecular weight of the subunit of Escherichia coli K12 aspartokinase I‐homoserine dehydrogenase I is 86000 ± 4000 instead of 60000 as previously published. The enzyme is a tetramer, not an hexamer. The electrophoretic homogeneity of the subunits, the number of unique sequences around cysteinyl and…

The intensity ratio of the 004 to the 002 diffraction line, I(004)/I(002), was measured for graphitizing C atoms, non-graphitizing C atoms, carbon blacks and a neutron-irradiated carbon. The values of I(004)/I(002) are different for different C atoms even when they have the same interlayer spacing d002. For example, a…

Contact angles have been measured using water drops of specified sizes, and in equilibrium with their vapor only, at their boiling point when residing on a copper surface at pressures ranging from 50–760 Torr.No appreciable change of contact angle with drop diameter was evident for sizes of 0.5 cm or more, but below t…
Certain samples of essential oils from Myoporum deserti , M. betcheanum , M. acuminatum , Eremophila maculata, and E. latrobei have been shown to contain myoporone and/or 10,ll-dehydromyoporone. The ambiguity regarding the stereochemistry of myoporone (previously known from M, bontioides) has been resolved,(-)-myoporo…
Dielectric and optical fatigue effects in 8/65/35 lanthana modified lead zirconate-lead titanate (PLZT) ferroelectric ceramics have been observed in respense to 60 Hz sine wave switching. Erratic behavior in Ee is attributable to microcracking near the surface electrodes. In addition, after N ∼ 105 cycles, the remanen…
Abstract Die beim atmosphärischen Rosten von Stahl entstehenden Korrosionprodukte wandeln sich unter geeigneten Bedingungen in Magnetit um, und zwar bevorzugt an den Eisen‐II‐sulfatnestern durch Reduktion von FeOOH durch metallisches Eisen. Im Gegensatz zur landläufigen Ansicht von der schützenden Wirkung des Magnetit…

Gallium is a metal that literally melts in your hand. It has low toxicity, near-zero vapor pressure, and a viscosity similar to water. Despite possessing a surface tension larger than any other liquid (near room temperature), gallium can form nonspherical ...Read More
Abstract Nuclear magnetic resonance (NMR) techniques have been applied in a considerable number of experimental studies of molecular and atomic motion in solids. In most experiments designed to measure diffusion parameters, the power spectrum of the random variation of local magnetic dipolar fields is determined direc…
