We review the literature on swimming in complex fluids. A classification is proposed by
comparing the length-and timescales of a swimmer with those of nearby obstacles …

An active fluid denotes a viscous suspension of particles, cells, or macromolecules able to
convert chemical energy into mechanical work by generating stresses on the microscale. By …

The Oldroyd 8-constant model is a continuum framework containing, as special cases, many
important constitutive equations for elastic liquids. When polymeric liquids undergo large …

Rheologists have expectations for signatures of linear viscoelastic properties, such as
shapes of G′(ω) and G ″(ω). Medium amplitude (or asymptotically-nonlinear) oscillatory …

In this paper, we provide a new exact framework for analyzing the most commonly measured
behaviors in large-amplitude oscillatory shear flow (LAOS), a popular flow for studying the …

We construct a microstructure-based constitutive model that successfully predicts
experimental rheology signatures that no other model has previously described. The …

When polymeric liquids undergo large‐amplitude shearing oscillations, the shear stress
responds as a Fourier series, the higher harmonics of which are caused by fluid nonlinearity …

At present, the structural changes of extruded materials under thermal-mechanical stress
during high-moisture extrusion are still unclear. In this study, the transglutaminase (TG) …

In the medium amplitude oscillatory shear (MAOS) test, intrinsic nonlinearity Q 0 (ω) derived
from Fourier-transform (FT)-rheology is an important material function for investigating the …

Recent work has focused on deepening our understanding of the molecular origins of the
higher harmonics that arise in the shear stress response of polymeric liquids in large …
