Seashells have superior mechanical properties. Conch shells, with bio‐assembled, hierarchical architectures of nano‐CaCO 3 laminas sandwiched between biopolymers, exhibit remarkable ferroelectric‐like hysteresis loops with giant electrical polarization, creating the possibility for materials for high density energy storage using a bottom‐up approach. More details can be found in the article by Xi Xiang Zhang and co‐workers on page 711 .
