Active dynamics of tissue shear flow

, 2016
We present a hydrodynamic theory to describe shear flows in developing epithelial tissues. We introduce hydrodynamic fields corresponding to state properties of constituent cells as well as a contribution to overall tissue shear flow due to ...

From 0D to 3D liquid crystal elastomers architectures: Fabrications and applications

Responsive Materials, EarlyView.
This review presents a dimension‐oriented overview of liquid crystal elastomers (LCEs), highlighting their molecular alignment, fabrication strategies, and programmable deformations from 0D particles to 3D architectures. Emphasis is placed on how dimensionality guides design principles, enables diverse actuation modes, and bridges fundamental ...

Dynamical arrest in active nematic turbulence

Physical Review Research
Active fluids display spontaneous turbulentlike flows known as active turbulence. Recent work revealed that these flows have universal features, independent of the material properties and of the presence of topological defects.

Unlocking the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces for adaptive cell modulation

Responsive Materials, EarlyView.
This Perspective discusses the potential of stimuli‐responsive liquid crystal polymer bio‐interfaces in modulating cell behavior as next generation dynamic artificial scaffolds. Unlike current artificial biomaterials that have static properties, LCPs offer fast, reversible, and spatially programmable deformation that reflects the dynamic properties of ...

Discontinuous transition to active nematic turbulence

Nature Communications
Active fluids exhibit chaotic flows at low Reynolds number known as active turbulence. Whereas the statistical properties of the chaotic flows are increasingly well understood, the nature of the transition from laminar to turbulent flows as activity ...

Rheology of Active-Particle Suspensions

, 2003
We study the interplay of activity, order and flow through a set of coarse-grained equations governing the hydrodynamic velocity, concentration and stress fields in a suspension of active, energy-dissipating particles. We make several predictions for the

Automated Identification of Thermal Transitions in Conjugated Material Thin Films Using In Situ Optical Spectroscopy

Small Methods, EarlyView.
This study demonstrates the effectiveness of in situ UV−vis coupled with automated data analysis, namely, ATLAS, for fast and reliable identification of multiple thermal transition in conjugated polymer thin films. This ATLAS method will significantly accelerate the understanding of the phase behavior of D‐A polymers with important implications for ...

Closed-Loop Control of Active Nematic Flows

Physical Review X
Stabilizing and shaping autonomous flows of active fluids is a fundamental challenge and a prerequisite for applications. We embed a light-responsive microtubule-based nematic in a proportional-integral control loop that adjusts the applied light ...
