Non-equilibrium structural and dynamic behaviors of active polymers in complex and crowded environments

G Zhu, L Gao, Y Sun, W Wei… - Reports on Progress in …, 2024 - iopscience.iop.org
Active matter systems, which convert internal chemical energy or energy from the
environment into directed motion, are ubiquitous in nature and exhibit a range of emerging …

Giant activity-induced stress plateau in entangled polymer solutions

D Breoni, C Kurzthaler, B Liebchen, H Löwen… - arXiv preprint arXiv …, 2023 - arxiv.org
We study the viscoelastic properties of highly entangled, flexible, self-propelled polymers
using Brownian dynamics simulations. Our results show that the active motion of the polymer …

Collecting–Gathering Biophysics of the Blackworm Lumbriculus variegatus

H Tuazon, C Nguyen, E Kaufman… - Integrative and …, 2023 - academic.oup.com
Many organisms exhibit collecting and gathering behaviors as a foraging and survival
method. Benthic macroinvertebrates are classified as collector–gatherers due to their …

Coil-to-globule collapse of active polymers: a Rouse perspective

P Malgaretti, E Locatelli, C Valeriani - Molecular Physics, 2024 - Taylor & Francis
We derive an effective Rouse model for tangentially active polymers, characterised by a
constant active force tangent to their backbone. In particular, we show that, once extended to …

Universal time and length scales of polar active polymer melts

MA Ubertini, E Locatelli, A Rosa - arXiv preprint arXiv:2404.08425, 2024 - arxiv.org
We present an in-depth multi-scale analysis of the conformations and dynamics of polar
active polymers, comparing very dilute and very dense conditions. We unveil characteristic …

Design and Implementation of a Hybrid‐Driven Soft Robot

K Zhang, Y Bi, R Zhang - Complexity, 2024 - Wiley Online Library
Currently, soft robots alone cannot obtain the same operating speed as rigid robots, while
rigid robots are not safe enough for human‐robot interaction. To address this problem, this …

Tangentially Active Polymers in Cylindrical Channels

J Martín-Roca, E Locatelli, V Bianco… - arXiv preprint arXiv …, 2024 - arxiv.org
We present an analytical and computational study characterizing the structural and
dynamical properties of an active filament confined in cylindrical channels. We first outline …

Traveling strings of active dipolar colloids

X Chao, K Skipper, CP Royall, S Henkes… - arXiv preprint arXiv …, 2024 - arxiv.org
We study an intriguing new type of self-assembled active colloidal polymer system in 3D. It is
obtained from a suspension of Janus particles in an electric field that induces parallel …

Upsurge of spontaneous knotting in polar diblock active polymers

M Vatin, E Orlandini, E Locatelli - arXiv preprint arXiv:2407.07191, 2024 - arxiv.org
Spontaneous formation of knots in long polymers at equilibrium is inevitable but becomes
rare in sufficiently short chains. Here, we show that knotting and knot complexity increase by …
