The tribological behaviour of glass filled polytetrafluoroethylene(PTFE) under dry and water lubrication
… additions of small amounts of additive such as molybdenum disulphide, MoS₂ and pigments on the wear rate of glass fibre filled PTFE was also investigated. The results show that the addition of glass fillers to PTFE reduce the wear of PTFE by three orders magnitude while keeping the coefficient …

Nanostructure Characterization, Fabrication and Devices of 2D Mos2 and Mos2/WS2 Hetrostructures
… Among all the transition metal dichalcogenides, molybdenum disulphide (MoS2) and tungsten disulphide (WS2) are explored most extensively since the last few years because of their complementary nature to metallic graphene. These thin 2D materials are semiconducting in nature, and moreover, bandgap …

Surface instabilities and interfacial phenomena for nanomanufacturing at the atomically-thin limit
Two-dimensional (2D) layered materials, exemplified by the prototypical graphene, have been intensively studied for their diverse material properties and superlative mechanical strength. Due to their atomically-thin nature, weak basal plane van der Waals interactions, and vanishing bending …
