An electrochromic display based on a Prussian-blue-modified electrode is described. Prussian blues are deposited electrochemically in a solution of ferric-ferricyanide. Current flow at +0.2 and +1.0 V is due to the reduction of Fe3+ and the oxidation of Fe2+ in the Prussian-blue coating, respectively. The result is a…

Description This publication provides information on the performance of zirconium and zirconium alloy components in nuclear application. Nuclear physicists have discovered that some materials -- zirconium, for example, provide much better neutron economy than conventional materials such as stainless steels.

A general definition of dynamic fragmentation can encompass any impulsive process which partitions a body of material into discrete domains. Two examples are fragmentation due to brittle fracture under impact loading and fragmentation due to shear banding in shock-compression plastic deformation. In application, predi…
A method of estimating diatom concentrations in sediment samples by the addition of known quantities of microspheres is described. Polystyrene or glass microspheres can be used and their concentration in suspensions can be rapidly calculated with an electronic particle counter. Test results are compared with results f…
The success or otherwise of catalyst preparation or modification depends on the availability of suitable characterization techniques to determine the condition of the catalyst. There are many techniques available for this purpose including x-ray powder diffraction, electron microscopy, photoelectron spectroscopy, and…
Approximate constitutive equations are proposed for use in the analysis of the rate-dependent deformation of metals at temperatures in excess of a homologous temperature of 0.5. The constitutive equations are formulated within the scope of some recent theories of elastoviscoplasticity with internal variables, but empl…
L'analyse des calibrations existantes pour différentes substances montre que l'intensité de l'absorption des I.R. de 3 µm par les hydroxyles dépend de la fréquence. Quand on prend en compte le facteur d'anisotropie γ, une raie unique de calibration pour le coefficient d'absorption molaire intégral I peut, en première…
Most of Volume 9A of Reviews in Mineralogy treats amphiboles and other hydrous pyriboles as isolated systems. It reviews the structural complexity and resulting chemical variability and diversity of petrologic behavior of amphiboles, whereby Volume 9A contains a hefty dose of petrology and in contrast, Volume 9B is de…
The temperature dependence of the structure factor of glassy ${\mathrm{As}}_{2}$${\mathrm{Se}}_{3}$ has been measured. Surprising results were found for the first peak, which shows a large increase in intensity from 40 K to the glass transition temperature, ${T}_{g}$; in contrast the second peak decreases in this rang…
The authors study a two-parameter one-dimensional lattice model embedded in three-dimensional space at T=0, that has indirect oscillatory interactions between neighbours. It can describe succession of modulated structures separated by first-order phase transitions. Qualitative agreement with experimental data obtained…
The molecular ordering in the nematic and smectic-C phases of the liquid crystal p-n-nonyloxy benzoic acid (NOBA) is investigated. The phase transition from isotropic to nematic phase is of first order. In the nematic phase over a wide range of temperatures the order parameter remained constant. In the low temperature…
Photo-stimulated luminescence provides a method of radiation dosimetry in which repeated readouts from an irradiated sample are possible without erasing the initial dose information. It is found that in CaSO4:Dy, photo-stimulated luminescence as well as thermoluminescence processes are both originating from the same t…
The stability of planar faults on possible slip planes in the DO19 structure is investigated using crystal symmetry considerations and the restoring force calculated for these faults. It is found that the superlattice intrinsic stacking fault on the basal plane and the antiphase boundaries on prismatic {1010} and {112…
The complex piezoelectric constants, d 21 , d 22 and d 23 , of ferroelectric AgNa(NO 2 ) 2 have been measured by two quasi-static methods; one is the optical interferometric method and the other is based on a comparison with the piezo-electric constant of quartz. The measurement covered the temperature range from 40°C…
Band structure calculations based on the extended Hückel method order energetically the 36 arsenic-like structures having the NaCl size unit cell in a way which is compatible with the observed crystal structures. Black phosphorus is the most stable of the 36, and the arsenic layer type is number seven. Energy differen…
