For those mechanisms which are significant, a more realistic model of the measurement system is analysed and corrections for the losses are provided. (UK)Shipley, D.RDuane, SD.R. Shipley, S. Duane, Heat Loss Mechanisms in a Measurement of Specific Heat Capacity of Graphite, CIRA (...
Monolayers of the methane derivative CF3H physisorbed on graphite have been investigated by calorimetry. The coverage-temperature phase diagram of a previous diffraction study has been refined. The melting and the antiferroelectric phase transition of the monolayer solid are identified as first-order ...
ac calorimetry was used to study the melting of CDfilms at submonolayer coverages. Near 131 K two sharp, closely spaced heat-capacity peaks indicative of a sequence of two first-order phase transitions are observed. The higher temperature peak is identified as melting. These results are compared...
The results of measurements of thermal conductivity, electric resistivity and heat capacity of graphites with density of 1·9 g/cm 3 and higher in the temperature range 50–2500°K are presented. On basis of the modified Debye equation average crystal parameters for the graphites investigated are...
A high specific heat capacity is desirable for PCMs so that the heat storage before and after the phase change is large. Latent heat capacity is the heat required to change the phase/state of a material at a constant temperature. Latent heat energy storage systems store thermal energy by ...
Heat capacities of physisorbed films on solids I. Nitrogen and carbon monoxide on graphiteHeat-capacity measurements have been made for N 2 and CO physically adsorbed on graphite (Grafoil GTA and MAT) at temperatures between 3 K and 80 K at submonolayer and monolayer coverages. Since there is...

This theory made it possible to explain the phenomena of scaling in the heat capacity of condensed matter. The scaling of specific heat of the carbon group elements with a diamond lattice is revisited. The predictions of the scaling characteristics for natural diamond and grey tin are verified ...
