parallel plate rheometer geometry (TA Instruments) that
was allowed to rotate in both directions, while the bottom plate
was a custom-machined 40 mm 1018 steel plate with varying
surface textures (Fig. 2B–D) that was attached to a temperature
controlled Peltier plate using Crystalbond, a thermo-reversible
adhesive, and remained fixed. The textured plate was aligned to
the axis of rotation of the rheometer by manipulating the screws
on the Peltier plate such that the misalignment of the system was
less than 1 μm of run out (defined as the difference between the
maximum and minimum deflection measured by a dial indicator
attached to the rotating shaft and contacting the bottom plate at
a radius R¼19.5 mm) [25].
