A surface force apparatus for nanorheology under large shear strain

, 2007
We describe a surface force apparatus designed to probe the rheology of a nanoconfined medium under large shear amplitudes (up to 500 $\mu$m). The instrument can be operated in closed-loop, controlling either the applied normal load or the thickness of ...
