Even in simple geometries, many complex fluids display nontrivial flow fields, with regions
where shear is concentrated. The possibility for such shear banding has been known for …

Viscoelastic fluids are a common subclass of rheologically complex materials that are
encountered in diverse fields from biology to polymer processing. Often the flows of …

The flow between concentric cylinders is routinely used in soft matter studies. In many cases,
the purpose of the setup is rheometric: the idea is to relate macroscopic changes in material …

We employ time-resolved flow velocimetry and birefringence imaging methods to study the
flow of a well-characterized shear-banding wormlike micellar solution around a novel glass …

Recent theories predict that discontinuous shear thickening (DST) involves an instability, the
nature of which remains elusive. Here, we explore unsteady dynamics in a dense cornstarch …

We introduce an modular fixture designed for stress-controlled rheometers to perform
simultaneous rheological and electrical measurements on strongly conductive complex …

We describe a technique coupling standard rheology and ultrasonic imaging with promising
applications to characterization of soft materials under shear. Plane wave imaging using an …

Since the seminal work of Taylor in 1923, Taylor–Couette (TC) flow has served as a
paradigm to study hydrodynamic instabilities and bifurcation phenomena. Transitions of …

We have investigated the uniaxial elongation behavior of six different wormlike micelle
systems covering a broad range of surfactant concentrations cs and salt/surfactant ratios R …

Capillary-driven thinning of a liquid bridge is commonly used to measure the extensional
rheology of macromolecular solutions for assessment of material sprayability, printability …
