Rapid perturbation of the 1A ⇌5T equilibrium in several Fe11 complexes occurs upon irradiation in the metal-to-ligand charge-transfer absorption region of the low-spin state, providing primary evidence for the formation of a 5T ligand field state from the initially populated charge-transfer state and permitting study…
The partitioning of aluminium between silicate melt (olivine tholeiite) and chromian spinel was studied experimentally. Runs were carried out at temperatures of 1 180˗1 300 °C and oxygen fugacities of 10⁻⁷˗10⁻⁹ atmosphere, at one atmosphere total pressure. The Al₂O₃ content of spinel is related to the Al₂O₃ content of…

Detailed measurements of the resistivity and the Hall coefficient have been made on high-quality single crystals of 2 H metallic transition-metal dichalcogenides between 4.2 K and 300 K, in order to investigate the carrier scattering mechanisms in a CDW system. The resistivity of 2 H -NbS 2 , which has no CDW transiti…

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…
