From report : "It has become apparent that pragmatic resonance data alone are insufficient to correctly evaluate crystal field parameters for rare-earth ethylsulfates, and that heat capacity data above 20°K are a useful aid in determining whether low lying levels obtained by absorption spectroscopy have been correctly identified."

From Abstract : "Phenomenal magnetostriction has been observed in Dy and Ho single crystals. ... [The} magnetostriction curve showed three slightly developed knees which agree well with the knees observed in the magnetization data for Ho previously reported."

From Abstract : "Dependence of boundary tension and capacitance at the mercury-aqueous 0.1 N HClO4 interface on polarization and organic solute concentration were determined for the colutes n-amyl alcohol and phenol. ... An earlier treatment proposed by this Laboratory based on a (non-thermodynamic) assumption of linear variation of surface charge density with coverage appears adequately justified for inference of fractional surface coverages near the electrocapillary maximum, but must be considered approximate for evaluation of molar area at full coverage in cases where linear variation of charge with coverage has not been demonstrated."

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 …

Literature review on the discovery, experiments on, and applications of the compound ThMg2.

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."

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."

Technical report. From Abstract : "The approximate transition ranges of a number of common indicators in tertiary butyl alcohol are given in terms of potentials measured with a glass-two phase salt bridge-SCE electrode system. Potential control was obtained by the addition of a sulfuric acid-malonic acid mixture and titration with tetrabutylammonium hydroxide. In general, the sulfonphthaleins are recommended for the titration of strong to medium strength acids, and Azo Violet, o-nitroaniline, and a p-nitro-p-aminoazobenzene for very weak acids."

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."

Technical report. From Abstract : "The Sr-SrH2 phase diagram was studied by thermal analysis, chemical analysis of equilibrated phases and X-ray diffraction. The maximum solubility of SrH2 in strontium metal is 38 mole % at the peritectic temperature of 880°C. Strontium metal undergoes an allotropic transformation at 555°C and melts at 768°C. A second transformation was found, at about 240°C, in samples containing hydrogen. Strontium hydride was found to have an allotropic transformation at 855°C."

Two principle reasons exist for the extension of high pressure research to temperatures near absolute zero. First, the comparison of certain data with theory (such as the pressure-volume relationship) is more meaningful if the effects of thermal vibrations can be ignored. Second, there are phenomena which can be studied only at low temperatures. These include superconductivity, the properties of solid helium and other inert gases, some electronic phenomena, etc.

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."

Technical report. From Introduction : "For more than a century, methods employed in preparing calcium were based largely on electrowinning and the most successful were based on [Sir Humphrey] Davy's process. ... In general, the metal was of adequate quality for the industrial applications of the time, and although by 1940 some strides had been made in the purification of calcium, interests in the better grades of the metal were limited essentially to experimental work of academic concern."

Technical report. From Abstract : "Details are provided on the construction and operation of a two-stage diaphragm pump successfully used for the first time in liquid metal service. From the results of 5,376 hr. test of the pump it was concluded that it is well suited to the pumping of liquid metals at low flow rates where pulsating flow can be tolerated and also where remote operation is required. Operating temperatures and pressures are limited only by the availability of suitable materials of construction."
