Active microrheology was conducted in living cells by applying an optical-trapping force to
vigorously fluctuating tracer beads with feedback-tracking technology. The complex shear …

The glassy cytoplasm, crowded with bio-macromolecules, is fluidized in living cells by
mechanical energy derived from metabolism. Characterizing the living cytoplasm as a …

The power of a macromolecular theory for the transport properties of a polymeric liquid
increases with the number of analytical expressions for its most important material functions …

A combination of experiments and Brownian Dynamics simulations is utilized to examine the
mechanisms of yielding and flow in attractive colloidal glasses during start-up shear flow. In …

Shear-induced microstructural changes are observed ubiquitously in materials as diverse as
hydrogels, or drilling fluids, as well as many consumer products. Superposition rheometry …

We study the shear rheological behavior of a commercial stereolithography paste
containing≈ 50 vol.% of zirconia particles (diameter≈ 100 nm) with the aim to clarify …

Understanding changes to microstructural dynamics under nonlinear deformations is critical
for designing flow processes of entangled polymeric fluids, motivating the development of …

Parallel superposition rheology has been explored using Brownian dynamics simulations on
a model colloidal gel by imposing a small amplitude probing oscillation parallel to the main …

The mechanisms of flow in suspensions of soft particles above the glass-transition volume
fraction and in the jammed state were probed using orthogonal superposition rheometry …

The novelty of this work is in its prediction of the non-Newtonian behavior of polymeric
liquids in the orthogonal superposition of small-amplitude oscillatory shear flow upon steady …
