Query: The role of friction in the yielding of adhesive non-Brownian
  suspensions   Yielding behavior is well known in attractive colloidal suspensions. Adhesive
non-Brownian suspensions, in which the interparticle bonds are due to
finite-size contacts, also show yielding behavior. We use a combination of
steady-state, oscillatory and shear-reversal rheology to probe the physical
origins of yielding in the latter class of materials, and find that yielding is
not simply a matter of breaking adhesive bonds, but involves unjamming from a
shear-jammed state in which the micro-structure has adapted to the direction of
the applied load. Comparison with a recent constraint-based rheology model
shows the importance of friction in determining the yield stress, suggesting
novel ways to tune the flow of such suspensions.
