Abstract
The shear response of molecularly thin liquid films on solid substrates when subjected to an applied air stress has been measured. The response corresponds to viscous friction while the same films sheared between two solid surfaces display static friction. These results show that molecularly thin liquid films partially confined by a single solid surface do not solidify as when confined between two solid surfaces. We are also able to observe several novel properties for liquid films on single solid surfaces not previously observed or expected.
