Geometry‐Dependent Adhesion in Transparent Monodomain Liquid Crystal Elastomers
Advanced Functional Materials, EarlyView.Liquid Crystal Elastomers (LCEs) are emerging as exciting pressure‐sensitive adhesives. We examine adhesion in chemically identical elastomer films, exploring the influence of geometry (director orientation) and phase (nematic or isotropic). We demonstrate the potential of these aligned films as transparent, tunable, broad‐temperature‐range smart ...

Universal scaling of active nematic turbulence [PDF]
, 2019 A landmark of turbulence is the emergence of universal scaling laws, such as Kolmogorov’s E ( q ) ~ q −5∕3 scaling of the kinetic energy spectrum of inertial turbulence with the wavevector q .

Spatially Tailorable Liquid Crystalline Elastomer Alignment During Digital Light Process 3D Printing
Advanced Functional Materials, EarlyView.Here, we report the fabrication of 3D printable liquid crystalline elastomer (LCE) structures with spatially tailorable alignment domains within the same layer. This work addresses the long‐standing challenge of preparing complex 3D LCE architectures with patterned functional domains to achieve nonlinear deformations. Fabrication of multi‐domains in 3D

Braiding Dynamics in Active Nematics
Frontiers in Physics, 2022 In active matter systems, energy consumed at the small scale by individual agents gives rise to emergent flows at large scales. For 2D active nematic microtubule (ANMT) systems, these flows are largely characterized by the dynamics of mobile defects in ...

Encoding Magnetic Anisotropies in Digital Light Processing 3D Printing
Advanced Functional Materials, EarlyView.A hybrid magnetic device—combining a coaxial coil within a nested Halbach array—is presented, integrated into a DLP 3D printer to enable spatially resolved magnetic field control. This system enables complex, multimodal responses by programming liquid crystal elastomer resins for magnetic and thermal actuation, and by inducing electrically conductive ...

Casimir stresses in active nematic films
New Journal of Physics, 2019 We calculate the Casimir stresses in a thin layer of active fluid with nematic order. By using a stochastic hydrodynamic approach for an active fluid layer of finite thickness L , we generalize the Casimir stress for nematic liquid crystals in thermal ...

Scaling Regimes of Active Turbulence with External Dissipation
Physical Review X, 2021 Active fluids exhibit complex turbulentlike flows at low Reynolds number. Recent work predicted that 2D active nematic turbulence follows scaling laws with universal exponents.

Liquid crystal based active electrocaloric regenerator
Heliyon, 2023 The active electrocaloric (EC) regenerator exploiting electric conversion into thermal energy has recently become important for developing a new generation of heat-management devices. We analyze an active EC regenerator numerically.

Flow transitions and length scales of a channel-confined active nematic.
Soft Matter, 2021 We perform lattice Boltzmann simulations of an active nematic fluid confined in a two-dimensional channel to study the range of flow states that are stabilised by the confinement: unidirectional flow, oscillatory flow, the dancing state, localised active
