Optimization of Phase-Change Material–Elastomer Composite and Integration in Kirigami-Inspired Voxel-Based Actuators

open access: yesFrontiers in Robotics and AI, 2021
Phase-change material–elastomer composite (PCMEC) actuators are composed of a soft elastomer matrix embedding a phase-change fluid, typically ethanol, in microbubbles. When increasing the temperature, the phase change in each bubble induces a macroscopic

Anomalous cell sorting behavior in mixed monolayers discloses hidden system complexities

open access: yesNew Journal of Physics, 2021
In tissue development, wound healing and aberrant cancer progression cell–cell interactions drive mixing and segregation of cellular composites. However, the exact nature of these interactions is unsettled.

Towards a thermodynamics of active matter [PDF]

open access: yesPhysical Review E, 2015
Self-propulsion allows living systems to display unusual collective behavior. Unlike passive systems in thermal equilibrium, active matter systems are not constrained by conventional thermodynamic laws. A question arises however as to what extent, if any, can concepts from classical thermodynamics be applied to nonequilibrium systems like active matter.

Alignments of a Microparticle Pair in a Glow Discharge

open access: yesMolecules, 2021
Stability of a vertically aligned microparticle pair in a stratified glow DC discharge is experimentally investigated. Using laser perturbations, it is shown that, for the same discharge parameters, a pair of microparticles can be suspended in two stable

Theoretical framework for two-microswimmer hydrodynamic interactions

open access: yesNew Journal of Physics, 2021
Hydrodynamic interactions are crucial for determining the cooperative behavior of microswimmers at low Reynolds numbers. Here we provide a comprehensive analysis of the scaling laws and the strength of the interactions in the case of a pair of three ...

Active matter [PDF]

open access: yesJournal of Statistical Mechanics: Theory and Experiment, 2017
Abstract The study of systems with sustained energy uptake and dissipation at the scale of the constituent particles is an area of central interest in nonequilibrium statistical physics. Identifying such systems as a distinct category—Active matter—unifies our understanding of autonomous collective movement in the living world and in ...

Spheroid mechanics and implications for cell invasion

open access: yesAdvances in Physics: X, 2021
Spheroids are widely used in vitro 3D multicellular model systems that mimic complex physiological microenvironments of tissues. As different cell types vary in deformability and adhesion, the choice of (heterogeneous) cell composition will define ...

Learning to control active matter [PDF]

open access: yesPhysical Review Research, 2021
The study of active matter has revealed novel non-equilibrium collective behaviors, illustrating their potential as a new materials platform. However, most work treat active matter as unregulated systems with uniform microscopic energy input, which we refer to as activity.
