This has some pretty bizarre consequences. If you could maximize the entropy in the system, temperature becomes discontinuous—it jumps from positive to negative infinity.

To meet the demand of ultrahigh-temperature thermal insulation, a novel porous dual-phase high-entropy ultrahigh-temperature ceramic (TiZrHfNbTa)C-(TiZrHfNbTa)B2 with outstanding merits is ...

Thermal insulation material is a critical part in thermal protection system (TPS) of the hypersonic vehicles. Recently, high-entropy ceramics has attracted great attentions in thermal insulation ...
