The development of refractory metal alloys for aerospace applications is reviewed. Refractory metals are prime candidates for many high temperature aerospace components because of their high melting points and inherent creep resistance. The use of refractory metals is often limited, however, by poor room temperature p…
A novel high activity, carbon supported, gold catalyst for acetylene hydrochlorination which can be successfully reactivated by HCl treatment is reported.
Novel Preisach-type models of hysteresis are introduced. Their distinctive feature is their ability to describe dynamic properties of hysteresis nonlinearities. The identification problem of fitting dynamic Preisach models to experimental data is discussed. Some recommendations concerning numerical implementation of t…

Local maxima and other singularities distinguish the temperature range 200-320°C in the electrostrictive versus temperature graph of Na0.5Bi0.5TiO3, known from other experiments as a region of coexistence of phases. Investigation of the pyroeffect in virgin Na0.5Bi0.5TiO3 single crystals reveals the existence of polar…

Abstract The structure of skin layer in injection‐molded polypropylen which displayed a clear two‐phase structure of skin and core has been studied by means of wide‐angle x‐ray diffraction, small‐angle x‐ray scattering, melting behavior, density, dynamic viscoelasticity, and tensile test. In skin layer, the c‐axis and…
The effect of experimental conditions on temperature-programmed reduction (t.p.r.) profiles has been studied. In the case of t.p.r. curves that include several reduction steps an inadequate selection of these parameters leads to distorted profiles; these distortions may produce a complete loss of resolution for the di…
This book provides a guide to the whole field of high voltage insulators as used in electrical power networks, traction and production. It covers historical development of the shapes - sometimes strange ones - of modern types, describes the principles materials both ceramic and polymeric and their fabrication, explain…

Abstract A simplified reaction kinetics model for long‐term P‐sorption in soils receiving large quantities of P‐rich animal manure is presented. Results from soil analyses for samples taken in 84 fields in nine different soil types indicate that the oxalate extractable P provides a good estimation of total P. Sorption…
The model has the following advantages over the classical Preisach (1935) model. First, it relaxes the congruency property of the classical model, which results in a broader area of applicability. For example, the hysteresis loops exhibited by the Stoner-Wohlfarth (1948) magnetic particles can be described by the nonl…
All articles of this category Iodoaromatic compounds are useful synthetic reagents for fine organic synthesis. Advances in the synthesis of aromatic iodo derivatives of various classes by the Sandmeyer reaction, direct iodination, iododethallation, and other methods are examined. Data concerning the synthesis of polyi…
LiCaAlF/sub 6/:Cr/sup 3+/ (Cr/sup 3+/:LiCAF) exhibits an intrinsic (extrapolated maximum) slope efficiency of 67%. For comparison, the intrinsic slope efficiencies of BeAl/sub 2/O/sub 4/:Cr/sup 3+/ (alexandrite), Na/sub 3/Ga/sub 2/Li/sub 3/F/sub 12/:Cr/sup 3+/ and ScBO/sub 3/:Cr/sup 3+/ were found to be 65, 28, and 26…

The transport properties of solids, as well as the many optical phenomena in them are determined by the scattering of current carriers. This book elucidates the state of the art in the research on the scattering mechanisms for current carriers in metals and semiconductors, and describes experiments in which these mech…
For pt.I see ibid., vol.ED-34, p.1008-17 (May 1987). The authors propose that the stress from two-dimensional oxide deformation affects the kinetic parameter in the Deal-Grove model (1965). In particular, the viscous stress associated with the nonuniform deformation of the oxide is identified as the fundamental force…
We have investigated the structural modifications of aqueous gelatin solutions for various thermal treatments and different concentrations. The structure is explored at different microscopic levels, putting into evidence the conformational coil ⇄ helix transition of the proteic chains (by optical rotation), the supram…
In recent years, much progress has been made in the understanding of interface dynamics of various systems: hydrodynamics, crystal growth, chemical reactions, and combustion. Dynamics of Curved Fronts is an important contribution to this field and will be an indispensable reference work for researchers and graduate st…
