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…

Abstract Magnetization mechanisms related to wall displacement and wall bulging are analyzed using a model previously proposed. In the case of the hysteresis loop, where both these combined mechanisms act, it is shown that the coercive force, the remanence and the shape of the loop, can be determined from the values o…

Using X‐ray diffraction techniques, thermal expansion and compressibility were measured on the orthorhombic compounds HfTiO 4 , Hf 1.26 Ti 0.74 O 4 , and ZrTiO 4 (both quenched and cooled slowly from 1300°C). The thermal expansion of HfTiO 4 is highly anisotropic; the thermal expansion coefficients along the crystallo…
Abstract The thermodynamics of metal/hydrogen systems are reviewed. Emphasis is placed on the thermodynamic properties of hydrogen dissolved in single solid phase regions. Methods of investigation are discussed. A brief survey of recent results on binary metal alloy/hydrogen systems is presented.
A rating of inhibitors in the order of their effectiveness is a relative matter and depends upon test conditions. The most important conditions are the degree of supersaturation and the temperature; the higher the supersaturation and the higher the temperature the less effective a scale inhibitor becomes. Scale Inhibi…
Abstract The fate of the secondary cartilage present on the membrane bones of the embryonic chick has been studied after immobilization. Immobilization was achieved by the in vivo injection of paralysing drugs (tubocurare or decamethonium), by grafting membrane bones onto the chorioallantoic membrane, or by organ‐cult…
