Niobium-Tin-Aluminum Alloy Studies (open access)

Niobium-Tin-Aluminum Alloy Studies

From Abstract : "A proposed constitutional diagram was developed from equilibrium data obtained for the niobium-tin binary alloy system. ... Alloying Nb3Sn with Nb3Al appears to raise the zero field superconducting transformation temperature of Nb3Sn slightly."

Acid-Base Reactions in Fused Salts. Dichromate-Bromate Reaction

Technical report. From Abstract : "The reaction of Lewis acid and base, Cr2O7= and BrO3_, in fused KNO3 - NaNO3 mixtures has been shown to involve an equilibrium followed by a slow decomposition to gaseous products."

The Strontium-Strontium Hydride Phase System (open access)

The Strontium-Strontium Hydride Phase System

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."

High Pressure Research at Low Temperatures (open access)

High Pressure Research at Low Temperatures

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.

Gamma Ray Efficiencies for Well Type Scintillation Crystals (open access)

Gamma Ray Efficiencies for Well Type Scintillation Crystals

From Abstract : "Gamma ray efficiencies for various sized well type NaI(Ti) crystals have been calculated using an IBM 704 digital computer. The adjustable parameters in the program are the gamma ray energy, the heights and diameters of the crystal and the well, the thickness of the well lining, and the positions of the (point) source inside the well. Some typical results are presented in graphical form."

Complex Systems of the Rare Earth Metals With Glycolate, Lactate, and α-Hydroxyisobutyrate Ligands (open access)

Complex Systems of the Rare Earth Metals With Glycolate, Lactate, and α-Hydroxyisobutyrate Ligands

From Abstract : "The solubilities of the individual rare earth lactates and α-hysroxyisobutyrates in water at 20 and 60° were determined for comparison with the rare earth glycolate solubilities determined earlier."
