2D Materials: Superlubricity between MoS2 Monolayers (Adv. Mater. 27/2017)

In article number 1701474, Kaihui Liu, Xianlong Wei, and co-workers demonstrate a test to measure friction between MoS₂ layers based on the sliding between them. This in situ scanning electron microscopy technique provides the first direct experimental evidence for superlubricity between atomic layers of hexagonal MoS₂.
