    • Hu et al. (Ref. 40) have also reported values for the shear stress between mica surfaces sliding at different velocities across an OMCTS film confined to thickness n=3, at shear rates and normal pressures comparable to those in the present study. Their results, however [and also a more recent study from the same group (Ref. 41)], indicated viscous rather than solidlike response (no yield stress at zero frequency was observed), and so contrast with our data as well as with the data of Gee et al. (Ref. 20) and Yoshizawa and Israelachvili (Ref. 21). Possible reasons for the discrepancy have been considered in paper I (Ref. 34, preceding paper).

    • A treatment somewhat in this spirit for shear of powder particles was presented by M. J. Adams (Ref. 7, p. 183) though in this model the friction between the powder particles themselves played a central role.
