Nanoparticle-enhanced PCM

Nanofluids or PCM slurries prepared from carrier fluids mixed with nanocapsules showed a significant increase in the capacity of heat transport values. In addition, nanocomposites made by nanomaterials with high thermal conductivity such as alumina and cupper nanoparticles, carbon nano-fibers, or and graphite nanoplatelets dispersed into paraffin can be used to enhance heat transfer and thermal properties [20]. Molecular dynamics simulations were performed by Rao et al. [20] to investigate the heat and mass transfer mechanism of nanoparticle-enhanced PCM and nano-encapsulated PCM. The nano-encapsulated PCM was studied using n-octadecane as core and SiO as shell material. Nanoparticle-enhanced PCM was studied by addition of Al nanoparticles with four different... 

When the phase boundary of a liquid is given by a metal, other phenomena occur. We have so far examined the case of specimens with the metal in a nanoparticle aggregation, with the opportune morphology of the metal subsystem (noble metals are more appropriate) Surface enhancement effects on the spectroscopic property of a chromophore have been evidenced, in agreement with the available experimental findings (especially for SERS, but also for other spectroscopic signals) [9]. In some experiments of this type, the metal is covered by a substance with a dielectric response differing from that of the bulk liquid, Which has also been introduced in PCM [9],...
