Here we present direct exfoliation of ultrathin silicon nanosheets from commercial powders through an improved liquid phase procedure. The feasibility was ascribed to the intrinsic anisotropic lattice structure, which allowed oriented propagations cryo-mediation-induced quenching cracks with assistance sonication. It also revealed that solid-solvent interface played a critical role in determining morphology exfoliated pieces as well efficiency. Moreover, due its superior morphology, enlarged...
