Science Daily  May 1, 2023 The direct connections between the macroscopic flow/deformation and microscopic structure or dynamics has not been determined. An international team of researchers (USA – University of Illinois, Argonne National Laboratory, South Korea, Canada) They probed the microstructural yielding dynamics of a concentrated colloidal system by performing creep/recovery tests with simultaneous collection of coherent scattering data via X-ray Photon Correlation Spectroscopy (XPCS). This combination of rheology and scattering allowed for time-resolved observations of the microstructural dynamics as yielding occurred, which could be linked back to the applied rheological deformation to form structure–property relations. Under sufficiently small, applied […]
