This précis is aimed as a practical field guide to situations in which shear banding might be
expected in complex fluids subject to an applied shear flow. Separately for several of the …

Injectable poly (ethylene glycol)(PEG)-based hydrogels were reversibly cross-linked through
thia-conjugate addition bonds and demonstrated to shear thicken at low shear rates. Cross …

Understanding how microscopic rearrangements manifest in macroscopic flow responses is
one of the central goals of nonlinear rheological studies. Using the sequence-of-physical …

Hypothesis The relaxation time in viscoelastic surfactant solutions is a function of
temperature, salt/surfactant concentrations, resting conditions, as well as shear frequency …

Two instantaneous dimensionless numbers that act as Deborah and Weissenberg numbers
are introduced to diagnose flow conditions for transient nonlinear rheology. The utility of the …

Hypothesis The self-assembly of long tail sugar-based surfactants into worm-like micelles
has recently been demonstrated, and the rheological properties of such systems have been …

The formation and evolution of a heterogeneous flow and flow reversal are examined in
highly elastic, gel-like wormlike micelles (WLMs) formed from an amphiphilic triblock …

Hypothesis The elastic contribution to the fluid dynamics of wormlike micellar solutions
makes these fluids unique due to the distinctive self-assembled micellar network formed by …

Nanoparticles have been mixed with viscoelastic surfactants to improve the thermal
sensitivity and elastic features of the original surfactant solution. The resulting mixtures have …

Water molecules can play a striking role in dictating the structure of supramolecular polymer
networks in apolar media, but the consequences on their viscoelasticity are not completely …
