Enhancing heat transfer in miniaturized radiators is an important goal for many researchers. In this study, silver nanofluids were employed to improve the transfer of heat in micro-pin fin heat sinks. A thermal constant analyzer measured the thermal conductivity of the silver nanofluid samples using the transient plane source (TPS) technique. Results showed that the addition of silver nanoparticles to the working fluids improved thermal conductivity, but at high concentrations, ...
In this paper, researchers synthesized monodispersed polystyrene spheres (PS), of a desired size. Generally, PS have a typical diameter ranging from 180 nm to 900 nm. However, the researchers in this study were able to reduce the sphere size, by increasing the polyvinylpyrolidone/styrene weight ratio. The PS were used as models, in order to fabricate hollow silica nanospheres (HSNSs), for thermal insulation applications. With modifications to this silica coating process, HSNSs ...
