Heat Capacity Measurements

A new complex [Na (H2O)2]6[MoCo6O12(H2O)12]·4.3H2O(s) was synthesized and determined by X-ray crystallography. Low-temperature heat capacities of the compound was measured by a precision automated adiabatic calorimeter over the temperature range from 78 to 380 K. An obvious dehydration process was found in the heat capacity curve of the title compound. The temperature, enthalpy and entropy of the dehydration process were determined to be (370.266±0.292) K, (187.455±0.354) kJ·mol-1, (50.627±0.078) J·K-1·mol-1 by three series of repeated heat capacity measurements in the region of thermal decomposition.

Semiconducting Behavior

Low-temperature resistivity, Seebeck coefficient, thermal conductivity, and heat-capacity measurements were performed on Ba8Ga16Sn30. This compound crystallizes in a cubic type-VIII clathrate phase, space group I¯43m, with the Baatoms residing inside voids created by a tetrahedrally bonded network of Ga andSn atoms. Ba8Ga16Sn30 exhibits semiconducting behavior above 150 K with a low thermal conductivity and thus may hold potential for thermoelectric applications.
