TL;DR: In this paper, the temperature dependence of the heat capacity of crystalline calcium-zirconium phosphate was studied over the temperature range 7-650 K by precision adiabatic vacuum and dynamic scanning calorimetry.
Abstract: The temperature dependence of the heat capacity Cpo = f(T) of crystalline calcium-zirconium phosphate was studied over the temperature range 7–650 K by precision adiabatic vacuum and dynamic scanning calorimetry. The experimental data were used to calculate the standard thermodynamic functions Cpo(T), Ho(T) − Ho(0), So(T), and Go(T) − Ho(0) at temperatures from T → 0 to 650 K and the standard entropy of formation of Ca0.5Zr2(PO4)3 at T = 298.15 K. The data on low-temperature (30 K ≤ T ≤ 50 K) heat capacity were used to calculate fractal dimension D. Conclusions about the character of the topology of the structure of the phosphate were drawn.

TL;DR: In this article, a mass-spectrometric method was used to measure the vapor pressure over the niobium-oxygen solid solution in the temperature range 2091-2379 K. The compositional dependence of the partial pressure of oxygen was observed to obey the Henry's law at low oxygen concentrations in Niobium metal.

TL;DR: In this article, the experimental determination of the standard molar enthalpies of formation in the condensed and gaseous phases, at T =298.15 K, of 5- and 6-nitroindazole was reported.
Abstract: The present work reports the experimental determination of the standard (p
o = 0.1 MPa) molar enthalpies of formation in the condensed and gaseous phases, at T = 298.15 K, of 5- and 6-nitroindazole. These results were derived from the measurements of the standard molar energies of combustion, using a static bomb calorimeter and from the standard molar enthalpies of sublimation derived by the application of Clausius–Clapeyron to the temperature dependence of the vapour pressures measured by the Knudsen effusion technique. The results are interpreted in terms of the energetic contributions of the nitro groups in the different positions of the aromatic ring.
