The authors present a method of producing Cu2CdSnSe4 quaternary nanocrystals using a colloidal synthesis route that could be used for future industrial synthesis. The nanocrystals prepared showed great potential for use as a thermoelectric material due to their high thermoelectric figure of merit (up to 0.71) resulting from a high electrical conductivity and low thermal conductivity. The authors believed that these properties could be further tuned in order to increase ...
The authors have dispersed mesoporous silica (MPSiO2) nanoparticles in water and determined the thermal conductivity for each of the resulting nanofluids. It was determined that the thermal conductivity of the nanofluid was greater than that of water, so these nanofluids have potential for use in heat exchanger applications....
The purpose of this study was to fabricate and analyze the physical properties of polyacrylate–gold nanocomposites (PGNs) with gold nanoparticles (GNPs) as their nucleation agents. The transient plane source (TPS) method was used to measure the thermal properties of the polyacrylate–gold nanocomposite foams (FPGNs) and PGNs. Results showed that the addition of GNPs improved thermal conductivity of the PGN materials, but as the size of GNPs increased, the ...
Cadmium sulfide (CdS) nanoparticles were dispersed in a polystyrene (PS) matrix to synthesize semiconducting optical nanocomposites for industrial applications. In this paper, many characteristics of the PS-CdS thick films were studied including thermal conductivity using the transient plane source (TPS) method. Results showed that the thermally conductive CdS nanoparticles enhanced the thermal conductivity of the nanocomposites....
Multiwalled carbon nanotubes (MWCNT) have applications in the aeronautic industry. This study examined how the concentration of MWCNT affects the electrical and thermal conductivities of nanocomposites. A thermal analyzer (TPS) measured the thermal properties of the nanocomposites using the transient plane source (TPS) technique. Results showed that thermal conductivity of the samples increased with MWCNT concentration and temperature, but the phenoxy-MWCNT nanocomposites had higher thermal properties than the PES-MWCNT nanocomposites....
