Join us at the International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES).
The thermal conductivities of aerogels and xerogels were explored in order to determine how the solid content of each material affected the conductivity. Experimental considerations include testing at room temperature, under vacuum and also under various humidity conditions. Density was taken into account and it was found that the optimal density for the gels was 0.15 g/mL....
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 ...
