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 ...

In the building and construction industry today, weather resistant and flame resistant materials have become fundamental. As such, silicone coated materials have been intensively researched, as they increase a given materials resistivity to heat and flames. Due to complications and time constraints when testing coating technologies in a lab setting, more enforcement has been placed on numerical methods. Based on stitching patterns, geometry models of the material and heat transfer ...

This article highlights two assumptions of TPS the technique; the probe is thermally neutral, and the heat transfer is conductive. The researchers of this article mention an uncertainty of using a technique for measuring low-density and highly insulative materials. Accordingly, numerically noised thermograms of the thermal responses were recorded and applied during measurements, and the best-fitting procedure of a technique was applied. From this, it was determined that the presence ...

Due to their high compressibility and resilience, nanofibrous aerogels (NFAs) have been proven to have positive insluative impacts on various applications with electronics and material damping. Up until this study, the fabrication of such nanofibers had proven to be very difficult. The scientists of this study homogenized nanofibre membranes, PAN/BA-a and SiO2 to create a nanofiber dispersion. This nanofiber dispersion was then freeze-dried to create uncrosslinked NFAs. The NFAs ...

When referring to maximizing the energy efficiency of a building, one must first look at the contents of the structure: the make-up of the interior and exterior walls and the contents of the buildings envelope. Generally, when we think of insulation, we think of thermal insulation, which protects us from the blistering, hot days in summer to the dreaded cold days of winter. However, when constructing a building one must ...
