The tetrahedrally close-packed structure of the μ-phase of Co7Mo6 has been investigated by the many-beam imaging with [110] axial illumination. Twinnings, stacking faults and other structure defects have been revealed in terms of characteristic coordination polyhedrons with the aid of multislice computations. Occurren…
Up to 4.7% ZnO can be incorporated into the crystalline lattice of C 3 S. Five allotropic forms (i.e. T I , T II , M I , M II , and R) can be stabilized at room temperature, depending on the amount of ZnO. When heated to high temperature, the C 3 S‐ZnO solid solution decomposes and ZnO escapes from the crystalline lat…

Using the Fokker–Planck equation as the basic description, various collective and single-particle properties of highly charged spherical macroparticles in solution are derived. The dynamic structure factor S(k,t) for finite k is found to be non-exponential in t due to the viscoelastic properties of the liquid of inter…
With a view to examining the failure-bearing capability of Zircaloy-4 cladding under postulated Loss-of-Coolant Accident condition in LWRs, integral tests of rod-burst, oxidation and thermal-shock were performed using simulated fuel containing A1203 pellets sheathed in Zircaloy-4 specimen cladding, filled with He gas,…
Killer yeast strains of Saccharomyces cerevisiae were firstly described by Bevan and Makower1} in 1963. Killer yeasts of the Saccharomyces and of other genera secrete
NiO/Al2O3–SiO2 catalysts containing 5 mol% NiO and various amounts of alumina have been prepared by precipitation. Nitrogen adsorption–desorption isotherms on both the calcined samples and the corresponding Al2O3–SiO2 precursors have been measured. Surface areas SB.E.T. and St have been calculated and the pore structu…
Connections between surface physics and biology are discussed. Special attention is paid to protein adsorption on solid surfaces, with relevance to biocompatibility and surface oriented diagnostic methods. Simple models for denaturation of proteins and interaction between antigens and antibodies on surfaces are develo…
Representative cathode half‐cell polarization data at low inlet cathode concentrations are presented for the MCCDC operated in the fuel‐cell mode. A mathematical model is used to correlate the cathode data and to explain the observed behavior, especially at high utilization. Also presented are representative cathode r…

Analyses of calcium content of molluscs collected from 53 freshwater habitats on a naturally occurring calcium gradient between the Canadian Shield and limestone formations in southern Ontario showed both intraspecific and interspecific variations in relation to pH, total alkalinity, total hardness and calcium hardnes…
The rate of "NO" reduction by carbon monoxide over calcined limestone was measured over a temperature range (588-922°C) by use of a fixed bed flow reactor. The calcined limestone was found to have a high catalytic activity for "NO" reduction by carbon monoxide and the obtained rate exceeds the rate of catalytic as wel…
Abstract
Ceramic materials based on the lanthanide orthophosphate series of compounds are known to be highly stable both chemically and physically. These characteristics have recently led to an extensive evaluation of these substances as potential primary containment media for the disposal of high-level radioactive wastes. Sin…

Comparison of the data for superplastic Pb–Sn eutectic with the existing theories on diffusion accommoda ted grain boundary sliding shows mixed agreement. In the superplastic region the observed deformation rates are about 102–103 times faster than Coble creep. In the present study, this discrepancy is resolved by a p…
The polyvinyl chloride (PVC) industry plays an important role in the total plastics industry of today. In most plastics producing countries, PVC is the leading plastic material; in others, for instance the United States and Japan, it is second only to polyethylene. The greater part of PVC is used as soft and plasticiz…
The mesitylgold(I) complex, (AuMes)5(Mes = 2,4,6-Me3C6H2), which has a five pointed star shape, was synthesized by the reaction of AuCOCl with a tetrahydrofuran solution of MesMgBr: the Au–C bond distances range from 2.12(2) to 2.20(2)Å.
Capacitive thermal-expansion, specific-heat, and electrical-resistivity measurements on single crystals of ${\mathrm{Eu}}_{3}$${\mathrm{S}}_{4}$ and ${\mathrm{La}}_{3}$${\mathrm{S}}_{4}$ have established for ${\mathrm{Eu}}_{3}$${\mathrm{S}}_{4}$ a first-order, nonstructural phase transition near ${T}_{t}=186$ K and th…
