Figure 13
Examples of in situ rheological and mechanical testing on ForMAX. Panels (a) and (b) show the Rheo–SWAXS and DMA–SWAXS setups on ForMAX, respectively, based on the Anton Paar MCR702 rheometer available on the beamline. The SAXS data of panel (c) collected from a suspension of cellulose nanocrystals (CNCs), presented as a function of scattering vector modulus q and azimuthal angle φ, show nanoscale alignment of the suspension along the flow direction. Panel (d) illustrates in situ polarized light imaging of shear-induced mesoscale alignment in the xz plane of a CNC suspension as a function of shear rate $[\dot{\gamma}]$ , with the same flow geometry sector visualized clockwise with increasing $[\dot{\gamma}]$ . The colored patterns contain information about mesoscale ordering of the CNC suspension.
