Technical report. From Abstract : "The reactions of VCl2. VCl3, and VCl3-VBr3 mixtures with bromine vapor at 350 to 450°C led to vaporization of the halides and deposition of mixed halides of vanadium (III) at lower temperatures."

Technical report. From Abstract : "The thallium-rich region of the thallium-indium phase diagram was determined from atmospheric pressure to 5.5 kbars primary from electrical resistivity data obtained as a function of composition, temperature, and pressure."

Technical report. From Abstract : "Magnetic moment measurements have been made on single crystals of terbium (hcp) with fields of 50 to 18,000 oe applied along the <1120> (a-axis), <1010> (b-axis), and <0001> (c-axis) directions. The temperature range covered was 1.4 to 500°K."

Abstract: "Abnormally short interatomic distances are characteristic of aluminum-transition element compounds which occur at the aluminum-rich ends of the phase diagram." Summary: "The theoretical model assumed in this investigation was that of spherical distribution of electrons centered about atomic sites in the V4Al23 structure, represented by the theoretical scattering factors for the isolated atoms. ...It is evident from the (Fo-Fc)-synthesis maps that too much scattering power has been assumed in the immediate vicinity of each atomic site since the negative regions associated with these sties represent electron density differences which are generally two to three times greater than the estimated experimental errors. ...An estimate of the number of electrons associated with the positive regions in the (Fo-Fc)-synthesis maps, and presumably the number of electrons participating in the bonding, could be obtained by computing structure facts with theoretical scattering factors which account for the contributions of the core electrons only. An (Fo-Fc)-synthesis with these Fc values and the Fo values from this investigation should then approximate the actual distribution of the outer electrons."

From abstract: "The dissociation of acids in tertiary butyl alcohol has been studied by potentiometric, spectrophotometric, and conductimetric methods. Values for the over-all dissociation of perchloric and picric acids and several tetrabutylammonium salts were estimated by the Fuoss-Kraus treatment of conductance data. Potentiometric studies were carried out at constant ionic strength in order to minimize activity coefficient variations. An acidity scale was established from potentiometric measurements at a glass electrode, and conductance values of dissociation constants. A method was developed for the evaluation of the over-all dissociation constant of weak acids using potentiometric data for hydrogen ion activities and conductance data for the corresponding anion activities. Over-all dissociation constants are reported for perchloric acid, picric acid, 2,4-dinitrophenol, and benzoic acid. Apparent dissociation constants from potentiometric measurements at a constant ionic strength were determined for hydrobromic, nitric, hydrochloric, picric, and p-toluenesulfonic acids."

Technical report. From Abstract : "The equilibria (1) VBr3(s) = VBr2(s) + 1/2Br2(g) and (2) 2VBr3(s) = VBr2(s) + VBr4(g) were studied over the range 644 to 805°K by transpiration in helium."

Technical report. From Abstract : "The vapor pressures of crystalline VCl2, VBr2, VCl3 and VBr3 have been measured by the Knudsen effusion method using pyrex and Vycor effusion cells. ... During the measurements on VCl3 and VBr3 dissociation and disproportionation of the samples occurred simultaneously with the simple vaporization. However, because the product of each of these processes was collected separately during an experiment, the vapor pressure due to sublimation was obtained without difficulty."
