their surroundings. Here, we review the numerical and theoretical modeling of active …

Open questions of chemically powered nano-and micromotors

W Wang - Journal of the American Chemical Society, 2023 - ACS Publications
Chemically powered nano-and micromotors are microscopic devices that convert chemical
energy into motion. Interest in these motors has grown over the past 20 years because they …

[HTML][HTML] Photochromism from wavelength-selective colloidal phase segregation

J Zheng, J Chen, Y Jin, Y Wen, Y Mu, C Wu, Y Wang… - Nature, 2023 - nature.com
Phase segregation is ubiquitously observed in immiscible mixtures, such as oil and water, in
which the mixing entropy is overcome by the segregation enthalpy,–. In monodispersed …

Phase diagram of active Brownian spheres: Crystallization and the metastability of motility-induced phase separation

AK Omar, K Klymko, T GrandPre, PL Geissler - Physical review letters, 2021 - APS
Motility-induced phase separation (MIPS), the phenomenon in which purely repulsive active
particles undergo a liquid-gas phase separation, is among the simplest and most widely …

Symmetry, thermodynamics, and topology in active matter

MJ Bowick, N Fakhri, MC Marchetti, S Ramaswamy - Physical Review X, 2022 - APS
The name active matter refers to any collection of entities that individually use free energy to
generate their own motion and forces. Through interactions, active particles spontaneously …

Chemical Micromotors Move Faster at Oil–Water Interfaces

J Liu, Z Yang, Z Yan, S Duan, X Chen… - Journal of the …, 2024 - ACS Publications
Many real-world scenarios involve interfaces, particularly liquid–liquid interfaces, that can
fundamentally alter the dynamics of colloids. This is poorly understood for chemically active …

Spatial velocity correlations in inertial systems of active Brownian particles

L Caprini, UMB Marconi - Soft Matter, 2021 - pubs.rsc.org
Recently, it has been discovered that systems of active Brownian particles (APB) at high
density organise their velocities into coherent domains showing large spatial structures in …

perturbations. We explore experimentally and computationally the topologically protected …

Generic rules for distinguishing autophoretic colloidal motors

Y Peng, P Xu, S Duan, J Liu, JL Moran… - Angewandte Chemie …, 2022 - Wiley Online Library
Distinguishing the operating mechanisms of nano‐and micromotors powered by chemical
gradients, ie “autophoresis”, holds the key for fundamental and applied reasons. In this …

Optimal active particle navigation meets machine learning (a)

M Nasiri, H Löwen, B Liebchen - Europhysics Letters, 2023 - iopscience.iop.org
The question of how “smart” active agents, like insects, microorganisms, or future colloidal
robots need to steer to optimally reach or discover a target, such as an odor source, food, or …
