This observed specific capacity improvement of Si/ACNT composite may be attributed to the formed 3-D conductive networks between silicon particles and interwoven ACNTs in the composite. Figure 4. Schematic illustration presents the fabriion of Si/ACNT composite using impregnation and in situ CVD method to grow the coiled ACNTs onto the silicon particles [ 44 ].
In this study, the properties of nanofluids just focus on specific heat and density. The analysis were using nanoparticles that always been used in industries and also that sited by previous researchers, there are alumina (Al2O), titanium dioxide (TiO2), copper oxide (CuO), silica (SiO2), zirconium dioxide (ZrO23), zinc oxide (ZnO), and silicon carbide (SiC).

However, silicon carbide exhibits excellent thermal resistance (meaning it can move more heat in a given time) and far fewer losses (meaning it can operate at higher temperatures). To determine how much power a SiC device can dissipate, we use a graph like the one shown on the right side of Figure 4, which gives the power density (W/mm2) for different types of devices.
Specific heat in this becomes the dimensionless unit (as specific heat of water is unity in MKS units). For gases there are two specific heats i.e., specific heat at constant volume c v and specific at constant pressure c p . c p is always greater than c v since any substance expands on heating and extra heat is required to raise the temperature by 1 degree in order to compensate for the
The specific heat of high‐purity Acheson graphite prepared by the National Carbon Company has been measured from 13 to 300 K. In the region 13° to 54°K the C p data follows a T 2 dependence quite accurately in agreement with previous experimental work and recent theoretical investigations of specific heat in strongly anisotropic solids.
