It all began with a bet. At a conference in Italy in 2013, Nicolas Vogel, then a postdoctoral fellow in Joanna Aizenberg’s lab at the Wyss Institute for Biologically Inspired Engineering at Harvard University and [...]
Controlling friction of graphene

02.02.2017 850 Views

Graphene, a wonder just one atom thick material, shows incredible wear-resistance and super low friction levels. This behavior is ascribed to its low inter-layer shear properties and high normal load carrying capabilities. However, in many [...]
Friction has memory
