The authors present a review of the thermal properties of graphene, and present one example of a practical application of graphene in thermal management, as an additive to phase change materials. It was found that the use of liquid-phase-exfoliated graphene as a filler in phase change materials has potential to enhance the thermal management in high-power
battery packs. The results also indicated that graphene had the ...

A composite phase change material (PCM) was formulated from commercial blended paraffin and a styrene-butadiene-styrene block. The thermo-physical properties of this composite PCM were then evaluated using the transient plane source method and differential scanning calorimetry. It was determined that there was a significant difference in the thermal conductivity of the PCM in the solid state when compared to that in the liquid state. The second part of this study ...

The effects of solid phase thermal conductivity, pore thermal conductivity, and pore volume fraction on the measured effective thermal conductivity of porous ceramics with pore volume fractions of 4 to 95% were investigated. The experimental results were then compared with pre-existing numerical models. It was found that the Maxwell-Eucken relation for closed porosity and the Landauer relation for open porosity were able to closely predict the effective thermal conductivity for tin oxide, ...

The low-temperature thermoelectric properties of Ca3-xDyxCo4O9+delta systems (x = 0, 0.02, 0.05, and 0.10). It was determined that these systems produced positive thermopower, indicating that the dominant carriers were holes. The electrical resistivity and thermal conductivity were found to decrease with increasing Dy3+ content, and the thermopower was found to increase. The highest calculated thermoelectric figure of merit was 0.044, and this was calculated for the Ca2.9Dy0.1Co4O9+delta sample....

Molten selenium, silver, cadmium, and tin were used to prepare a-Se, and a-Se98M2 (M = Ag, Cd, and Sn) alloys in order to determine the thermo-physical properties of these materials using the transient plane source technique. In order for these alloys to be used in industrial applications such as phase change optical storage, photo electrochemical solar cells, and holographic recording systems, among others, their thermal transport properties needed to be ...
