We study, for directional solidification or fusion of binary mixtures, the stability of planar fronts against one-dimensional deformations. We extend the perturbative approach of Wollkind and Segel to the case where solute diffusion in the « daughter » phase in non-negligible. We study the bifurcation diagram and calc…
The mechanism by which photoreceptor cells in the eyes of higher animals absorb light, giving rise to receptor potentials that initiate the visual process, is a subject of active research in biophysics today. The pace of this research and its multidisciplinary nature have made it difficult for the nonexpert to keep ab…
Concentrated polystyrene latices form strongly interacting systems, and under appropriate conditions of particle radii, volume fraction and ionic strength the repulsive forces can be strong enough to give rise to measurable viscoelastic behaviour. In this paper an experimental investigation of the viscoelastic behavio…
The specific heat of the organic superconductor (TMTSF)2ClO 4 has been measured between 0.4 and 2 K. A large anomaly of the electronic contribution at 1.22 K has been attributed to the onset of three-dimensional superconducting order. There is a large magnetic field dependence of the electronic contribution above 1.22…
Shear-modulus data for polystyrene latices at various volume fractions and sodium chloride concentrations are compared with a simple model based on the theory of interaction between electrical double layers. Stress relaxation and low shear-rate viscosity are also discussed in the context of particle interaction forces.
Frustration is produced in crystals of the KDP family by mixing ferroelectric and antiferroelectric constituents. Birefringence and dielectric measurements are reported for 0 ≤ x ≲ 0.35. They indicate an interesting phase diagram, with a glassy phase probably preceded by a mixed phase for the upper part of the concent…
In Wyoming Bentonite the ion-exchange reactions for the homovalent pairs Ag(en)+2–Cs+ and Cu(en)2+2–Ca2+ and for the heterovalent pair Ag(en)+2–Cu(en)2+2 are characterized by ΔG⊖ values of exchange which are very much larger than those for the aqueous metal ions. These effects, which emphasize the importance of ion–li…
Abstract Development of crystallizers . The control of the crystallization kinetics and the spatial variation of the crystal mass are of decisive importance for the operation of industrial crystallizers. The influence of micro‐ and macro‐attrition is demonstrated with particular reference to collisions with impeller b…
The paper describes the properties of a high strength precipitation hardened wrought cupro-nickel alloy suitable for high integrity components, particularly in marine environments.
An apparatus has been developed for creep rupture testing in high-pressure hydrogen up to 49.1 MPa at elevated temperatures up to 873 K. The apparatus is designed to facilitate the measurement of the actual load on the specimen with an external load cell irrespective of axial load caused by high pressure in the vessel…
Cabrerite, (Ni₂.₂ Mg₀.₇ Fe₀.₁)(AsO₄)₂ • 8 H₂O, from Laurium (Greece), crystallizes in space group C2/m, with a = 10.211(6), b = 13.335(3), c = 4.728(3) Å, β = 104.97°, Z = 2. The crystal structure of cabrerite had been refined starting from the parameters of vivianite. Anisotropic least squares refinement (R = 0.046),…
This paper evaluates the resistance to intergranular stress-corrosion cracking (IGSCC) in the boiling water reactor of several grades and compositions of austenitic stainless steel castings. A specific objective of this work was to predict the performance of Alloy Casting Institute CF3, CF3A, and CF8 castings in nucle…
By means of X-ray diffraction method, we determined the lattice parameters and phase transition temperatures of specimen of K0.5Bi0.5TiO3—Na0.5Bi0.5TiO3 system with varions components, as well as the component of the boundary between tetragonal and rhombohedral forms. The X-ray powder diffraction data of K0.5Bi0.5TiO3…
Abstract The effect of chloride ions on the corrosion behaviour of binary iron‐nickel alloys in sulphuric acid solutions has been investigated using polarization resistance and potentiodynamic polarization measurements. A moderate inhibition effect of the chloride ions on the corrosion of these alloys has been found,…
Specific heat capacity measurements were made in a differential scanning calorimeter on a series of eight crosslinked epoxy/diamine polymers over a range of temperatures chosen, for each polymer, to include the glass transition. The tabular data at 5°C intervals was then fitted to a five-parameter empirical equation t…

The interaction of displacement damage and transmutant helium is thought to be an important factor in the evolution of cavity microstructures. A plausible sequence of events involves the growth of bubbles to a critical size or critical number of helium atoms. Above this critical size, determined by the local point def…
