Abstract The luminescence properties of Bi 3+ ‐activated Cs 2 NaYCl 6 crystals are presented. The Bi 3+ ion (6s 2 ) occupies an Y 3+ site which has cubic symmetry. Excitation in the A absorption band yields 3 T 1u emission. Excitation in the C absorption band, however, yields 3 T 1u and 3 A 1u emission, because both l…

It has recently been proposed that the anomalous specific heat of uranium dioxide be ascribed to the effect of electronic defects rather than Frenkel disorder on the union sub-lattice. We here present calculations showing that the entropy contribution from electronic defects is large enough to make a major contributio…

Abstract The Tulameen coal field is part of an Eocene nonmarine basin which received extensive volcaniclastic sediments due to its location within an active magmatic arc. Bentonite partings in the coal originally consisted of glassy rhyolitic tephra with phenocrysts of sanidine, biotite, and quartz. During the initial…

A method of visualizing the 180°-domain structure in TGS type crystals by means of nematic liquid crystals (NLC) is described. The possibility of visualization is due to the different orientation of NLC molecules on the domains with opposite orientation. The method enables the observation of static domain structure on…

The spectroscopic constants of hydroxyl ions formed from hydrogen, deuterium, and tritium in a potassium tantalate (KTaO3) host have been determined. These isotopes were found to diffuse readily either into or out of KTaO3 single crystals. At T=77 K the infrared absorption band due to the OH−, OD−, or OT− stretching v…

Abstract Poly(ester amides) with physical properties similar to those of liquid crystalline polyesters were prepared by acidolysis of poly(ethylene terephthalate) with p ‐acetamidobenzoic acid and then polycondensation through the acetamido and carboxyl groups. The ester amide polymers had a random sequence distributi…

Abstract The oxidations of ferrocene (FcH) and n ‐butylferrocene (FcBu) by ferric salts (nitrate or bromide) are strongly inhibited by aqueous cetyltrimethylammonium bromide and nitrate (CTABr and CTANO 3 , respectively). The kinetics of inhibition fit a model in which the substrates are distributed between water, and…

The width of symmetrical, threefold stacking‐fault nodes in a Cu‐13–43 at. % Al alloy has been measured as a function of node character by means of weak‐beam electron microscopy. The stacking‐fault energy (γ) has been determined independently of the measurement of the width of single, straight, dissociated dislocation…

Empirical fits to data are obtained which determine the backscattered electron coefficient for films of arbitrary thickness and electrons of normal incidence over the energy range 20–53 keV for the elements Al, Cu, Ag, Au, and Bi. From this is derived a ’’universal’’ fit which describes with reasonable accuracy the ba…
