主　　题：bonding rational biomaterials 

摘      要：Hydrogen bonds are non-covalent interactions and essential for assembling supermolecules into ordered structures in biological systems,endowing crystals with fascinating physical properties,and inspiring the construction of eco-friendly electromechanical ***,the interplay between hydrogen bonding and the physical properties is not fully understood at the molecular ***,we demonstrate that the physical property of biological crystals with double-layer structures could be enhanced by rationally controlling hydrogen bonding interactions between amino and carboxyl *** hydrogen bonding interactions result in various thermal,mechanical,electronic,and piezoelectric *** particular,the weak interaction between O and H atoms contributes to low mechanical strength that permits important ion displacement under stress,giving rise to a strong piezoelectric *** study not only reveals the correlation between the hydrogen bonding and physical properties in double-layer structures of biological crystals but also demonstrates the potential of these crystals as functional biomaterials for high-performance energy-harvesting *** calculations and experimental verifications in this work provide new insights into the rational design of biomaterials with desirable physical properties for bioelectrical devices by modulating intermolecular interactions.
