Mass spectrometric determination of the heat of vaporization of some solid elements

Thermochemistry and oxidation potentials of the platinum group metals and their compounds

“…We adopt the entropies of Rh(e) and Rh(g) tabulated by Kelley and King (112). Four investigations (8,58,96,144) of the heat of sublimation of rhodium are in good agreement with °298 = 133 kcal mole-1. Combination of this value with the entropies leads to (7{0 for Rh(g).…”

“…Their results lead to values of AHt°= -104 and -109 kcal mole-1 for PtCl4-2(aq). The AHf°values above combined with AGt°lead to S2°= 64,48,54,8,104, and 87 cal deg-1 mole-1 for PtCl4-2(aq). Since we are unable to make a completely objective choice between these conflicting data, the best we are able to do is to arbitrarily adopt "reasonable" values of S2°= (44) cal deg-1 mole-1 and AHt°= -122 kcal mole-1 for PtCl4-2(aq).…”

From metal nanowires to ultrathin crystalline ALD nanotubes: process development and mechanism revealed by in situ TEM heating experiments

“…38 The heat of vaporization of copper is given as 3.3 eV. 39 Decreasing the size of materials down to the nanometer range also leads to a decreasing melting temperature. 40 By applying the thermodynamic model to calculate the melting temperature for NWs derived by Sar et al , 41 the nano-size copper has a melting temperature of around 1010 °C.…”
