This article reported on the synthesis, characterization, life cycle assessment (LCA) of nano insulation materials (NIMs) that are made of hollow silica nanospheres (HSNSs). The transient plane source (TPS) technique was used to determine the thermal properties of the HSNSs. The thermal conductivity of the ...
Buildings are responsible for a large portion of the world’s energy use, so there is a high global demand for cost-efficient thermal insulating materials. In this paper, the thermal properties of hollow silica nanosphere nano insulation materials (HSNS NIMs) were examined to test their ...
The authors present the synthesis of hollow silica nanospheres (HSNSs) by a template-assisted approach using polystyrene nanospheres as templates. These nanospheres could potentially be used as nano insulation materials due to their low thermal conductivity ~0.02 W/m K. The authors also examined the environmental footprint ...
The authors present a method of preparation of TiO2 nanotubes by alkaline treatment (with NaOH) of TiO2 particles followed by acid-washing and annealing treatment. Theoretical and experimental studies on the thermal conductivity of TiO2 nanotubes is also presented. The thermal conductivity values determined experimentally matched ...
Monodisperse hollow silica nanospheres with an outer diameter of ~300nm were prepared for the comparison of thermal conductivity with similar solid silica nanospheres. It was found that the thermal conductivity of the hollow nanospheres was lower than that of the solid silica nanospheres....
