Chemically bonded multi-nanolayer inorganic aerogel with a record-low thermal conductivity in a vacuum

Hongxuan Yu et al.

Summary: In this study, a chemically bonded multi-nanolayer design and synthesis method was developed to enhance the mechanical and thermal properties of inorganic aerogels. The aerogels exhibited low density, ultrahigh flexibility, and excellent thermostability, as well as the lowest thermal conductivities among solid materials to date. This unique combination of properties makes them an attractive material system for thermal superinsulation at extreme conditions.

Versatility of infrared properties of MXenes

Meikang Han et al.

Summary: We have found that the MXene family of two-dimensional carbides and carbonitrides can produce selective and ultrathin films and coatings with different infrared emissivity values and colors. By combining different metals in solid-solution MXenes, the infrared emissivity can be finely tuned. Furthermore, the infrared identification capability has been validated using different MXene coatings and patterned MXene fabrics. MXenes' versatility at optical and infrared wavelengths provides a platform for developing MXene-based smart, flexible devices and wearables capable of selective and localized thermal management.
