Summary: This study investigates the effect of surfactants (non-ionic, cationic, or anionic) on alumina aerogels. The findings show that the charge-charge interactions between surfactants and cationic inorganic species in the aluminum precursor influence the pore structure of the aerogels. Controlling the surfactant concentration allows for control over the pore structure of the aerogels.

Summary: In this study, a high-performance room temperature gas-sensing material was successfully developed by utilizing MXene and reduced graphene oxide as building blocks. The resulting 3D aerogel shows excellent acetone-sensing performance at room temperature, with fast response and recovery times, as well as good reproducibility and selectivity. This strategy of composite 3D graphene/MXene architectures with metal oxide semiconductors provides a new pathway for future development of room temperature gas sensors.

Summary: A new model was proposed to calculate the optical path of the granular aerogel layer in the Aerogel Glazing System (AGS). Through geometric optics, the optical path of a single aerogel granule was calculated and converted into a homogeneous distribution in the inhomogeneous distribution of aerogel granules. The calculated optical path was used to simulate the spectral transmittance of different AGSs and evaluate their energy performances under different weather conditions.

Summary: In this study, superhydrophobic, heat-resistant alumina-methylsilsesquioxane hybrid aerogels (AlMSAs) were prepared to overcome the problem of hydrophilicity and thermal coarsening. The transformation from hydrophilicity to hydrophobicity was achieved by adjusting the molar ratio of methyltriethoxysilane. The AlMSA2 exhibited homogeneous superhydrophobicity and superior heat resistance, making it a promising material for high-moisture and high-temperature thermal insulation applications.

Summary: In this study, a SiBCN/SiC dual network ceramic composite aerogel was prepared using electrospinning, sol-gel technology, and supercritical drying technology. The results showed that the double network structure improved the heat transfer problem and reduced the thermal conductivity of the SiC fiber network, resulting in a composite aerogel with lower thermal conductivity and excellent compressive properties.

Summary: A high-temperature accelerometer is developed using an improved graphene aerogel (GA) as the sensitive material, which operates continuously at 1073 K and intermittently at 1273 K. The accelerometer exhibits lightweight, high sensitivity, wide frequency response, stability, repeatability, and low nonlinearity error due to the excellent and stable mechanical properties of the improved GA. This accelerometer can be a promising candidate for high-temperature vibration sensing in space stations, planetary rovers, and other equipment.
