Summary: This study investigated the effect of organically modified vermiculite clay loading on the rheological properties and flammability of bio-based high-density polyethylene/organically modified vermiculite clay biocomposites. The results showed that an appropriate loading of the organically modified vermiculite clay improved the dispersion and rheological behavior of the biocomposites, while having little impact on tensile and impact strength. In contrast, loading unmodified vermiculite clay reduced the burning rate.

Summary: Sodium hydroxide was used as a base catalyst to reduce the flammability of PVA aerogels, resulting in significantly enhanced compressive moduli and decreased onset of decomposition temperature. The presence of the base appears to hinder the polymer pyrolysis process, leading instead to the formation of dense char. Unexpected base-catalyzed dehydration occurs at fire temperatures, causing a dramatic decrease in heat release when the base is added.

Summary: The incorporation of polymeric components into clay-based aerogels significantly improves their physical and thermal properties. In this study, clay-based aerogels were produced by incorporating angico gum and sodium alginate into ball clay using a simple and ecologically acceptable mixing method and freeze-drying. The compression test showed the aerogels had a low density spongy material. The microstructural characteristics were investigated using XRD and SEM, and the chemical structure was studied using FTIR. The results suggest that these aerogels have potential applications as thermal insulation materials.

Summary: In this study, aramid pulps (AP) were used to reinforce clay aerogel composites, which showed improved mechanical strength, good thermal insulation, and fire resistance. The composites exhibited an isotropic lamella-honeycomb porous structure, and with the increase of AP content, the low density, low thermal conductivity, and mechanical strength were maintained. The detailed heat transfer process and improved thermal stability and fire resistance of the composites were analyzed. This research provides new insights into the development of thermal-insulating, fire-safe, and high-strength thermal insulation materials.

Summary: In this study, a green analytical method was developed to measure furfuryl alcohol in foods using tailored ion chromatography equipped with a UV detector. The method showed good calibration curve fitting and comparable method detection limit to liquid chromatography methods. The properties and reactivity of furfuryl alcohol were examined, providing evidence on the formation of singlet oxygen. The presented findings help clarify a controversy about the O-1(2) formation possibility by certain reactions.

Summary: Ceramic aerogels have attractive properties for applications in various fields due to their high porosity, low density, high specific surface area, low thermal conductivity, and thermal stability. However, the brittleness of conventional ceramic aerogels hinders their practical use. Resilient ceramic aerogels have overcome the brittleness issue but still exhibit brittleness under tensile stress and limited load-bearing ability. In this short review paper, strategies for modifying the mechanical properties of resilient ceramic aerogels are discussed, including the deformation and moving ability of nanowire building blocks and the deformation resistance provided by the aerogel architecture. Perspectives for further modification are also explored.

Summary: This study investigates the influence of two flame retardants on polyurethane foam (PUR) systems, focusing on their thermal and mechanical properties. The results show that the flame retardants significantly improve the fire resistance of the PUR systems without affecting thermal conductivity, and only slightly decreasing the mechanical properties. These findings suggest that the presented systems can be applied as thermal insulation where both low heat conductivity and high flame resistance are required.

Summary: The study introduces a fully bio-based, low fire-hazard and superelastic aerogel without any cross-linkers for excellent thermal insulation and oil absorption. The aerogel showed benefits such as anisotropic super-elasticity, hydrophobicity, low density, and high flame retardancy, making it ideal for environmental applications. Additionally, the aerogel exhibited great selectively oil clean-up absorption with high absorption capacity and fastest separation rates of oil/water mixture.
