Surface Energy, Surface Debye Temperature and Specific Heat of Nanocrystals

Surface Debye Temperatures and Specific Heat of Nanocrystals

The present study deals with the contribution of the surface atomic layer to the specific heat of nanocrystals. In the case of small phases with comparable number of bulk and surface atoms, the variation of heat capacity with respect to that of infinitely large phase is significant. To evaluate this variation, in the framework of the classical Debye model, we introduce surface excess heat capac...

Investigation of Impervious surface and Urban Surface Temperature in Qaemshahr

Information on a variation of impervious surface is useful for understanding urbanization and its impacts on the hydrological cycle, water management, surface energy balances, urban heat island, and biodiversity. This research attempts to detect impervious surfaces and its changes by satellite imagery in Qaemshahr. The relationship between impervious surfaces and changes in land surface tempera...

Measurement of Boundary Conditions - Surface Heat Flux and Surface Temperature

In order to understand a heat transfer phenomenon, it is sometimes very important to know the change in heat flux and temperature with time or the distribution of the heat flux and temperature on the surface of a heating block. Furthermore, with the development of computational thermal-fluid dynamics, experimental data that are of the CFD level, both spatially and temporally, are needed to vali...
