CsOH: Low-temperature heat capacity and high-temperature enthalpy increment

Street-heat: Controlling road temperature via low enthalpy geothermal energy

In this paper, the authors present an idea to exploit low enthalpy geothermal energy in order to reduce street temperature fluctuations throughout the year and avoid ice formation during the winter season. The key aspect of the proposed system is that it is based on the exploitation of geothermal temperature gradients through materials with high thermal conductivity inserted into the ground, su...

Low-temperature excess heat capacity in fresnoite glass and crystal

The effect of thermal annealing on low-temperature excess heat capacity was investigated in fresnoite (Ba2TiSi2O8) glass. The amplitudes of the excess heat capacity decreased, and their positions shifted to a higher temperature by relaxation or crystallization. In particular, we revealed that the change in the excess heat capacity during transition from the glassy state to the crystalline state...

Low Temperature Heat Capacity and Thermodynamic Properties of Zinc Ferrite*

The heat capacity of zinc ferrite (ZnFe,O,) has been determined over the range 5 to 350°K. Molal values of C~,S’, and HO-H,O computed from the thermal data are 32,99&t-0.03 cal/deg., 36.01 f0.03 cal/deg., and 18,00&0.02 Cal, respectively, at 298,lS”K. A co-operative thermal anomaly associated with antiferromagnetic ordering occurs at 9.5” and extends toward higher temperatures probably as a con...

Low-temperature Normal-state Heat Capacity of Tungsten

Temperature dependence of three-body hydrophobic interactions: potential of mean force, enthalpy, entropy, heat capacity, and nonadditivity.

Temperature-dependent three-body hydrophobic interactions are investigated by extensive constant-pressure simulations of methane-like nonpolar solutes in TIP4P model water at six temperatures. A multiple-body hydrophobic interaction is considered to be (i) additive, (ii) cooperative, or (iii) anti-cooperative if its potential of mean force (PMF) is (i) equal to, (ii) smaller than, or (iii) larg...
