测量了固体基底上分子薄液膜在空气应力作用下的剪切响应。响应对应于粘性摩擦，而在两个固体表面之间剪切的相同的膜显示静摩擦。这些结果表明，分子薄液膜部分地限制在一个单一的固体表面不固化时，限制在两个固体表面之间。我们还能够观察到几个新的属性，液体膜在单一的固体表面上以前没有观察到或预期。
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.
