Title: Unraveling the Role of Order-to-Disorder Transition in Shear Thickening Suspensions

Using high resolution in situ small angle x-ray scattering in conjunction with oscillatory shear on highly monodisperse silica suspensions, we demonstrate that an order-to-disorder transition leads to a dynamic shear thickening in a lower stress regime than the standard steady shear thickening. We show that the order-to-disorder transition is controlled by strain, which is distinguishably different from steady shear thickening which is a stress related phenomenon. The appearance of this two-step shear thinning and thickening transition is also influenced by particle size, monodispersity and measurement conditions (i.e. oscillatory shear vs. steady shear). Our results show definitively that the order-to-disorder transition induced thickening is completely unrelated to the mechanism that drives the steady shear thickening.
