Propagation Characteristics of Capillary Ripples II. Instrumentation for Measurement of Ripple Velocity and Amplitude

Technical report. From Abstract : "An instrument for measuring the propagation velocity of capillary ripples to within 0.3% and for measuring the amplitude of such ripples to within 1 to 10% (depending upon amplitude) was designed and constructed. The principle components of the instrument were a Teflon Langmuir trough (with provision for automatic recording of compression data); generating and receiving probes consisting of a thin rod and a razor blade respectively mounted so that the rod and razor edge were parallel and accurately placed in the surface to be studied."

The Crystal Structure of Bismuth Subchloride

Technical report. From Abstract : "The stoichiometric formula of the lower chloride in the BiCl3-Bi system has been established as Bi12Cl14 (BiCl1.167) through a dingle crystal, X-ray determination of its structure. ... Previous studies of the Bi-Cl3-Bi system are re-examined in the light of the structural results."

Solution of Metals in Their Molten Salts. Some Manganese, Chromium, Uranium and Antimony Systems (open access)

Solution of Metals in Their Molten Salts. Some Manganese, Chromium, Uranium and Antimony Systems

Technical report. From Abstract : "Preparations of high purity MnCl2, CrCl2, CrI2, UBr4, UI3 and Sb4S3 are described; the melting points obtained for CrI2 (868°) and Sb2S3 (559.5°) are significantly higher than previously reported. The small solubilities of manganese and chromium in the respective halides studied were characterized primarily by the depression of the freezing points of the salts by excess metal."

A Study of the Rare Earth Metal Propionate Complexes (open access)

A Study of the Rare Earth Metal Propionate Complexes

Technical report. From Abstract : "The first two successive formation constants of the trivalent rare earth metals with the proportionate ligand were determined by a potentiometric method. A comparison was made of the trends in the stability constants of the proportionate ligand as one proceeds through the rare earth series with the trends observed for several other ligands. Attempts to explain some of the trends have been summarized."

Propagation Characteristics of Capillary Ripples, I. The Theory of Velocity Dispersion and Amplitude Attenuation of Plane Capillary Waves on Viscoelastic Films (open access)

Propagation Characteristics of Capillary Ripples, I. The Theory of Velocity Dispersion and Amplitude Attenuation of Plane Capillary Waves on Viscoelastic Films

From abstract: "The boundary value problem for velocity of propagation and attenuation of capillary ripples over viscoelastic surface films is set up and solved from the viewpoint of continuum hydrodynamics. Both soluble and insoluble films are treated. Successive approximation methods are used to derive explicit formulae for velocity of propagation and amplitude attenuation; formulae for these quantities accurate to second order are given for slightly viscoelastic and highly viscoelastic films, and formulae accurate to first order are given for films of intermediate viscoelasticity."

The Uranium-Rhenium Alloy System (open access)

The Uranium-Rhenium Alloy System

Abstract The phase diagram of the uranium-rhenium alloy system is presented along with a discussion on transformation kinetics of the uranium solid solutions. The phase diagram is of the double eutectic type with the intermediate phase having the composition URe2. This phase exhibits allotropy at 180°C and melts congruently at 2200°C. URe2 reacts sluggishly with the uranium solid solutions below 750°C to form the peritectoid compound U2Re. Eutectic reactions occur at 1105° and 2105°C at respective compositions of 10.5 and 65.5 wt. % Re. Eutectoid reactions occur at 643° and 681°C at compositions of 1.4 and 6 wt. % Re, respectively. The maximum solubility of rhenium in α uranium is about 0.4 wt. % at 643°C and in β uranium is 1.9 wt. % at 681°C. The solubility of rhenium in γ uranium is 6 wt. % at 681°C and increases to about 7 wt. % at 975°C. The solubility of uranium in rhenium is 0.6 wt. % at room temperature with little variation up to 2000°C. Alloys of β and γ uranium containing more than about 1.2 and 7 wt. % Re respectively, can be readily supercooled to room temperature. Rapid cooling of γ alloys containing less than about …

The Solubility of Holmium in Copper, Silver, and Gold

From Abstract: "The solid solubility of holmium in copper, silver, and gold was determined using metallographic techniques. The composition of the first intermetallic compound in these systems was found to be Cu4Ho, Ag7Ho2, and Au3Ho. These compounds form eutectics with the solvent metals which melt at 868, 787, and 778°C respectively."
