Isobaric heat capacities in the liquid and in the solid phases of seven isomeric pentanols were measured by adiabatic calorimetry. Results obtained cover the following temperature ranges:  2-methyl-1-butanol from 85 K to 301 K; 2-methyl-2-butanol from 84 K to 301 K; 3-methyl-1-butanol from 79 K to 158 K; 3-methyl-2-butanol from 85 K to 301 K; 2,2-dimethyl-1-propanol from 6 K to 381 K; 2-pentanol from 80 K to 301 K; and 3-pentanol from 5 K to 309 K. The temperature and enthalpy of phase transition were also determined. Solid to solid and solid to liquid phase transitions were detected for 2-methyl-2-butanol and for 2,2-dimethyl-1-propanol, and a solid to liquid phase transition was detected for 3-pentanol. Only a glass to liquid phase transition was detected for all the remaining compounds. The heat capacity data in the liquid phase obtained in this work were merged with available experimental data from the literature and critically assessed, and sets of recommended data were developed by correlating selected data as a function of temperature.

The thermodynamic properties of uranium nitride chloride, UNCI(s) have been measured. From the low-temperature adiabatic heat capacity measurements in the temperature range (5 to 420) K, the values COp,m and SOp,m, (68.08 ± 0.10) J·K-I·mOr l and (96.54 ± 0.10) J·K-I·mOr l , respectively, have been obtained. The high-temperature function has been derived by use of two separate techniques. Enthalpy increments has been determined by drop-calorimetry in the temperature range (399.2 to 932.6) K and the heat capacity in the temperature range (305 to 1086) K has been measured by DSC. Combination of these results with the earlier determined standard molar enthalpy of formation of dfHom(UNCI, s 298.15 K) = (559 ± 4) kJ·mor l , the thermodynamic properties have been calculated up to T = 1100 K. Furthermore, in the heat capacity measurements a phase transition at T =32 K has been observed, the nature of this transition has been studied by neutron diffraction.
