This article investigates how the thermal conductivity of a resorcinol-formaldehyde aerogels varies with increasing resorcinol (R) to water (W) ratios. The thermal conductivity was measured using a transient plane source (TPS) method. As the R:W increases so does the thermal conductivity, this is because there is more conductive solids present to transfer more energy....
In this study, ultralow density silica aerogels were synthesized and their thermal conductivities were tested to determine how supercritical drying affected the samples. A thermal analyzer measured the thermal conductivity of the silica aerogels using the transient plane source (TPS) method which determined that the thermal conductivity of silica aerogels increased with temperature....
Phosphosilicate ceramics with varying compositions were synthesized through the sol-gel process and the thermal conductivity of the samples was measured using the transient plane source (TPS) method. Results showed that the thermal conductivity of phosphosilicate ceramic powder was low, but increased slightly with phosphorous concentration. The low thermal conductivity of the ceramics could be useful in thermal barrier applications....
Carbon nanotubes (CNTs) combined with inorganic matrices are not structurally sound unlike singular CNTs which have good mechanical performances. Borosilicate glass, commercially known as Pyrex, is durable but has yet to be successfully fabricated using the sol-gel technique. In this paper, the sol-gel technique was used to manufacture borosilicate glass matrix composites with multi-walled carbon nanotubes (MWCNTs). The technique measured thermal conductivity of the materials using the transient plane source (...
