An empirical rule is found for both ordered and disordered structures that the thermal conductivity tends to decrease as the distance of the constituent X increases in the horizontal direction from the location of Ni and Pt in the periodic table. This trend is quite isomorphic with that of ...
As can be seen thermal conductivity did not show any predictive trend with total number of carbons (Fig. 10a). The thermal conductivity measured in the solid-state at room temperature for the PCMs, alkanes, and sugar alcohols fit in an apparent sigmoidal curve as a function of the number ...
Hence to extend the application and statistical power of the trend analyses, system parameters such as nanoparticle material must be fixed. Thus, the scope of the present critical analysis was reduced to experimental thermal conductivity performance of alumina–water nanofluids. Thermal conductivity was ...
Anyway both the proposed Mod.Klemens and rev.Klemens method show the best agreement with respect to the experimental trend. In our vision, the introduction of the parameter d in the model allows a more accurate description of these mixed composition compounds because it takes into account the ...
Here we show how each dopant in group IV (C, Si, and Ge), in its neutral and charged forms, affects the thermal conductivity of BAs. This unveils a general trend, where neutral impurities reduce the thermal conductivity more strongly than charged ones. We offer an interpretation in terms ...
(4) is derived forr = 50 μm. The losses are seen to vary from about 8 to 85%, while the general trend is clearly nonlinear. The latter may result from the porosity and specific orientation of the samples, in particular the holes, with respect to the gravity vector, which ...
When the temperature is above 100 °C, there is an opposite trend between the in-plane and out-of-plane thermal conductivities. Table 3 Experimentally determined and predicted thermal conductivities of 3D C/SiC composites Full size table In addition, the heat flux distribution and heat fields in...
In this low-pressure region, we observed a clear change in the electrical conductivity trend in the calculated results for both 5 and 10 wt% NaCl(aq). For 10 wt% NaCl(aq), this transition point is ∼500 MPa, which does not appear to depend significantly on temperature. This was also...
A similar trend was also found for the use of cPCM in CBM, where the thermal conductivity of mortar was found to decrease by 13.8%, 21.0%, 26.2% and 33.6% with the incorporation of 10%, 15% 20% and 30% of cPCM, respectively [82]. A similar range of reduction was observed in Ref...
metastable states in the hybrid, as seen in the schematics in Fig.3b. This trend between spin-state and conductance is in agreement with previous reports on electron transport measurements directly across SCO crystals5or nanorods6,37and thin films of SCO nanoparticles/carbon nanotubes composites7. ...
