Study of the corrosion behaviour of high temperature alloys in helium containing low concentrations of impurities has been stimulated by the development of the High Temperature Reactor (HTR), a graphite moderated ceramic fuelled nuclear system with a helium coolant in which the metallic structural materials are requir…
The passivating effect of molybdate ion on the corrosion of titanium in deaerated, boiling 1N H2SO4 has been explored. In this medium, in the absence of molybdate ion, titanium rapidly corrodes. An immediate passivation process for Ti is observed when Mo+6 at a concentration as low as 3 mM is added to an H2SO4 solutio…
A cytoplasmic fructose-1,6-diphosphate-dependent lactate dehydrogenase (LDH; EC 1.1.1.27) from Streptococcus mutans OMZ175 was purified to homogeneity as judged by sodium dodecyl sulfate-gel electrophoresis. The purification consisted of ammonium sulfate precipitation of the cytoplasmic fraction, DEAE-Sephacel and Blu…
Abstract Die bisher unbekannten Verbindungen Ba 3 Fe 2 O 5 Cl 2 (A) und Ba 3 Fe 2 O 5 Br 2 (B) wurden in einkristalliner Form dargestellt und mit Vierkreisdiffraktometermessungen untersucht. Beide Verbindungen kristallisieren mit kubischer Symmetrie (Raumgruppe 12 1 3−T 5 ) mit (A) a = 9,9705(3) und (B) a = 10,0039(8)…
A new technique is described for the isolation and enumeration of cyanobacteria‐lysing Streptomyces spp from soil or water. Two cyanobacteria, Anabaena cylindrica (ACTT 27899) and Tolypothrix tenuis (ATCC 27914) were used as the test organisms. Ten‐day‐old cyanobacterial cultures were vacuum‐filtered to form a lawn on…
A finite element model is proposed to analyze in-pile fission gas release from UO2 fuel. The model describes fission gas transfer from grain interior to grain boundaries by simultaneous mechanisms of diffusive flow and boundary sweeping, considering the effect of irradiation-induced resolution in grain boundaries. The…

Optical absorption and emission measurements are reported for the Cs2NaDyCl6 and Cs2NaYCl6: Dy3+(5 mol %) systems under variable-temperature (10–298 K) conditions. For both systems, the data are compatible with the retention of octahedral (Oh) site symmetry at the Dy3+ ions over the entire 298 to 10 K temperature rang…
Fifteen papers written by technical leaders in the field and presented as a comprehensive symposium held at Case Western Reserve University. Authors thoroughly handle the subject matter by analyzing current problems and presenting their theories and the results of research projects. The information is practical and ti…

TItrachlorodibenzo-p-dioxin (TCDD) and related halogenated aromatic hydrocarbons are a highly toxic class of environmental contaminants, as evidenced by numerous cases of accidental poisonings of human and animal populations and their extreme toxic potency in laboratory animals.The proposed model for the mechanism of…

Abstract Photoisomerization of 3-(aryicarbamoyl)norbornadiene-2-carboxylic acid 1 to the corresponding quadricyclane derivative 2 in an aqueous alkaline solution was clean and dependent upon the p-substituent of the aryl group. The exothermically reversal reaction of 2 to 1 was also clean but independent upon the subs…
The equilibrium vaporization reactions and have been studied by mass‐loss effusion in the temperature range 1237–1401 K. The results were combined with published calorimetric data for nickel‐rich samples and static phosphorus‐dissociation pressure data for phosphorus‐rich samples, with consideration of the requirement…
Article The Influence of Experimental Conditions upon the Measurements of Hydrogen Diffusion in Palladium by Electrochemical Permeation Methods* was published on February 1, 1985 in the journal Zeitschrift für Physikalische Chemie (volume 146, issue 2).
Abstract An XPS study of the oxides formed on GaAs at ambient temperature and in ambient atmosphere is reported. Special attention has been paid to the interpretation of the Ga 3d and As 3d energy levels. By varying the angle between energy analysed electrons and the surface of the sample the depth distribution of the…
