AbstractTooth enamel, and especially the outer tooth enamel, is a load-resistant shell that benefits mastication but is easily damaged, driving the need for enamel-restorative materials with comparable properties to restore the mastication function and protect the teeth. Synthesizing an enamel analog that mimics the components and hierarchical structure of natural tooth enamel is a promising way to achieve these comparable mechanical properties, but it is still challenging to realize.

AbstractMonoatomic-layered carbon materials, such as graphene1 and amorphous monolayer carbon2,3, have stimulated intense fundamental and applied research owing to their unprecedented physical properties and a wide range of promising applications4,5. So far, such materials have mainly been produced by chemical vapour deposition, which typically requires stringent reaction conditions compared to solution-phase synthesis.

Oxide glasses can be intrinsically toughened by forming crystal-like, medium-range order clusters, which transform inversely to the amorphous state under stress, exciting multiple shear bands for plastic deformation. With their history traced back to 3500 bc, glasses have been considered as one of the most important materials for humankind with huge contributions to human civilization.
