Measured TMAC and slip length of 1 atm nitrogen gas on OTS-coated glass. Different symbols represent different sphere-plate pairs prepared by the same method (set 1: diamonds, set 2: circles, set 3: triangles). The slip length data in the bottom pane were used to calculate the accommodation coefficients for the same sphere-plate pair in the top pane. and symbols show the TMAC for two sets of bare glass surfaces.
