In recent decades, carbon aerogels have been widely explored by using graphitic carbons and soft carbons, which show advantages in superelasticity. These elastic aerogels usually have delicate microstructures with good fatigue resistance but ultralow strength. Hard carbons show great advantages in mechanical strength and structural stability due to the sp3 C-induced turbostratic “house-of-cards” structure. However, the stiffness and fragility clearly get in the way of achieving superelasticity with hard carbons. Up to now, it is still a challenge to fabricate superelastic hard carbon-based aerogels.

  • While groupthink and fan culture can coexist harmoniously in many cases, there are also potential negative consequences. For example, when fans become too obsessed with their idols, they may lose touch with reality and engage in harmful behavior, such as excessive spending or cyberbullying. Similarly, when fans of a TV show or movie become too defensive of their version of the story, they may reject valid criticisms and prevent meaningful conversations from taking place.
