Roughness-controlled Tribocharging Governs Friction in Dry Glass Contacts
Liang Peng, Begum Demirkurt, Thibault Roch +3
Friction is commonly reduced by polishing surfaces, based on the idea that roughness enhances mechanical interlocking and thus friction. Here we show that, for dry glass-glass cont…

The Decrease of Static Friction Coefficient with Interface Growth from Single to Multiasperity Contact
Liang Peng, Thibault Roch, Daniel Bonn +1
The key parameter for describing frictional strength at the onset of sliding is the static friction coefficient. Yet, how the static friction coefficient emerges at the macroscale…
