Density,conductance, transference numbers,and diffusion measurements in concentrated solutions of nickel chloride at 25°C

The Hittorf technique for measuring transference numbers has been modified to produce precise data in concentrated aqueous electrolyte solutions. Density, molar conductance, transference number, tracer-diffusion, and mutual diffusion data are reported for aqueous NiCl₂ solutions up to 4M concentration at 25°C.Visiting Fellow at the Australian National University on leave from the School of Chemical Sciences, Universiti Sains Malaysia, Penang, Malaysia.     

The heat capacity of Cu2Te(c), CuTe(c), Ag2Te(c) And Ag1.64 Te(c)

The heat capacities and enthalpies of Cu₂Te(c), CuTe(c), Ag₂Te(c) and Ag_1.64Te(c) have been measured for the temperature range (280–8OO K) using differential scanning calorimetry. Several transitions were observed in these substances and the enthalpies associated with these transitions have been determined.     

Electroproduction of π0 mesons in the resonance region at q2=1.0 (GeV/c)2

Data are presented for the reaction ep → epπ⁰ at a nominal momentum transfer squared of 1.0 (GeV/c)². The data were obtained using an extracted electron beam from NINA and two magnetic spectrometers for coincidence detection of the electron and proton. Differential cross sections have been measured for isobar masses in the range 1.19–1.73 GeV/c².

Stationary inverted Lyman populations and free-free and bound-free emission of lower-energy state hydride ion formed by an exothermic catalytic reaction of atomic hydrogen and certain group I catalysts

Rb⁺ to Rb²⁺ and 2K⁺ to K + K²⁺ each provide a reaction with a net enthalpy equal to the potential energy of atomic hydrogen. The presence of these gaseous ions with thermally dissociated hydrogen formed a plasma having strong VUV emission with a stationary inverted Lyman population. Significant Balmer α line broadening of 18 and 9 eV was observed from a rt-plasma of hydrogen with KNO₃, and RbNO₃, respectively, compared to 3 eV from a hydrogen microwave plasma. The reaction was exothermic since excess power of about 20 mW/cc was measured by Calvet calorimetry. We propose an energetic catalytic reaction involving a resonance energy transfer between hydrogen atoms and Rb⁺ or 2K⁺ to form a very stable novel hydride ion. Its predicted binding energy of 3.0471 eV with the fine structure was observed at 4071 Å, and its predicted bound-free hyperfine structure lines matched those observed for about 40 lines to within.01 percent. Characteristic emission from each catalyst was observed. This catalytic reaction may pump a CW HI laser.
