title: Facile and efficient exfoliation of inorganic layered materials using liquid alkali metal alloys.
abstract: A facile and efficient exfoliation process has been reported to produce single- and few-layer nanosheets of MoS2, WS2 and BN using liquid alloys of alkali metals at room temperature. The colloidal dispersions of MoS2 and WS2 layers were highly stable over several months, which allowed us to easily prepare films of MoS2 and WS2 by vacuum filtration or spraying.
