Clay aerogels are typically used for insulation, filtration and absorption, and are typically favored because of their eco-friendly nature, low density and high porosity. Unfortunately, these aerogels are limiting due to their relatively high fragility. Researchers in this study aimed to create fracture-free pectin/clay aerogel monoliths. In this process, water was used as the solvent and montmorillonite as the solute. Morphologies, thermal stability and conductivity of the monoliths were ...

Silica aerogels (SA) are identified as one of the most advanced thermal insulating materials to date, however, their range of applications is limited due to a high sensitivity to moisture and issues with brittleness. This study highlights the design and fabrication of a new and improved thermal insulation material, robust flexible hybrid silica nanofiber (SNF)-SA membranes. To allow for higher thermal insulating characteristics, these membranes form an interpenetrating network ...

Insulation is a vital component in the construction industry, notably in this study, glass wool. Maximizing the hydrothermal performance of glass wool is key when dealing with water vapor, humidity and permeability. Although insulation does not generally come in contact with liquids, it is important to consider all outcomes, with likelihood of accidents occurring and the varying levels of workmanship. The transient technique was employed to thermally characterize glass wool ...

This article discusses the creation and characterization of albumin based rigid and elastic foams. These foams were created using formaldehyde as the hardener for the protein, while camphor was used as the plasticizer. Crosslinking was carried out using a traditional or microwave oven. Samples differed in the amount of water, formaldehyde, and camphor added, and in the amount of time that they spent in the oven. The thermal conductivity was ...

The ability of leading thermal conductivity measurement techniques to be applied to the thermal measurement of thermally insulated materials was investigated. Researchers required that the equipment be able to operate between temperatures of 250 and 800°C. The equipment studied included the Transient Plane Source, the laser flash technique, the guarded heat flow meter, the transient hot wire instrument, and the guarded hot plate apparatus. Variables considered by the investigators included price, ...
