DESCRIPTION:Speaker: Joshua Dijksman\nhosted by Scott Waitukaitis\nAbstract
 : You know the nearer your destination\, the more // you realize you dont 
 understand rheology. Take the case of dense hydrogel suspensions. These so
 lid-fluid like materials display a myriad of remarkable features. The micr
 oscopic origin of their behavior is poorly understood\, despite them being
  just a collection of simple\, soft\, slippery particles. We test the hydr
 ogel packing mechanics via rheology and custom intruder tests\, both in tr
 ansient and steady state normal and rotation driving\, and via stress and 
 strain control modes. Our findings highlight the short\, strong but reprod
 ucible shear history dependence of the packing\, various rate dependencies
  and a sensitivity to boundary conditions. The results will be discussed i
 n the context of the observed relaxation dynamics in particle-level contac
 t mechanics.[1] J.A. Dijksman\, T. Mullin\, Confinement controls the creep
