Velocity Weakening in Anisotropic Friction on a Tilted Titania Nanorod Forest
Debottam Datta, Enrico Gnecco, J. P. Singh +1
In this study, we demonstrate velocity-dependent directional friction on a surface structured with tilted (~57°) titania nanorods using standard and colloidal probe force microsco…

Avalanche Dynamics in Stick-Slip Cutting of Molybdenum Disulfide
Pawel Koczanowski, Paolo Nicolini, Hesam Khaksar +1
We have investigated nanoscale wear on multilayered MoS2, the flagship transition metal dichalcogenide, by elastically driving sharp diamond tips under normal loads sufficient to i…
