Osmosis, from molecular insights to large-scale applications

S Marbach, L Bocquet - Chemical Society Reviews, 2019 - pubs.rsc.org
Osmosis is a universal phenomenon occurring in a broad variety of processes and fields. It
is the archetype of entropic forces, both trivial in its fundamental expression–the van't Hoff …

Interactions in active colloids

B Liebchen, AK Mukhopadhyay - Journal of Physics: Condensed …, 2021 - iopscience.iop.org
The past two decades have seen a remarkable progress in the development of synthetic
colloidal agents which are capable of creating directed motion in an unbiased environment …

Collapse dynamics of chemically active flexible polymer

N Jain, S Thakur - Macromolecules, 2022 - ACS Publications
We investigate the structural and dynamical properties of a chemically active flexible
polymer chain immersed in a solvent bath by using hybrid molecular dynamics (MD) and …

Chemical micromotors self-assemble and self-propel by spontaneous symmetry breaking

T Yu, P Chuphal, S Thakur, SY Reigh… - Chemical …, 2018 - pubs.rsc.org
Self-propelling chemical motors have thus far required the fabrication of Janus particles with
an asymmetric catalyst distribution. Here, we demonstrate that simple, isotropic colloids can …

Diffusiophoresis in cells: A general nonequilibrium, nonmotor mechanism for the metabolism-dependent transport of particles in cells

RP Sear - Physical Review Letters, 2019 - APS
The more we learn about the cytoplasm of cells, the more we realize that the cytoplasm is
not uniform but instead is highly inhomogeneous. In any inhomogeneous solution, there are …

Exact phoretic interaction of two chemically active particles

B Nasouri, R Golestanian - Physical review letters, 2020 - APS
We study the nonequilibrium interaction of two isotropic chemically active particles taking
into account the exact near-field chemical interactions as well as hydrodynamic interactions …

Isotropic active colloids: explicit vs. implicit descriptions of propulsion mechanisms

J Decayeux, J Fries, V Dahirel, M Jardat, P Illien - Soft Matter, 2023 - pubs.rsc.org
Modeling the couplings between active particles often neglects the possible many-body
effects that control the propulsion mechanism. Accounting for such effects requires the …

Collective behavior of active molecules: Dynamic clusters, holes, and active fractalytes

S Fehlinger, B Liebchen - Physical Review Research, 2023 - APS
Recent experiments have led to active colloidal molecules, which aggregate from nonmotile
building blocks and acquire self-propulsion through their nonreciprocal interactions. Here …

Diffusiophoretic Brownian dynamics: characterization of hydrodynamic effects for an active chemoattractive polymer

S Jaiswal, M Ripoll, S Thakur - Macromolecules, 2024 - ACS Publications
The phoretic Brownian dynamics method is shown here to be an effective approach to
simulate the properties of colloidal chemophoretic based systems. The method is then …

Effective squirmer models for self-phoretic chemically active spherical colloids

MN Popescu, WE Uspal, Z Eskandari… - The European Physical …, 2018 - Springer
Various aspects of self-motility of chemically active colloids in Newtonian fluids can be
captured by simple models for their chemical activity plus a phoretic-slip hydrodynamic …
