[HTML][HTML] The interplay of shape and catalyst distribution in the yield of compressible flow microreactors

GC Antunes, M Jiménez-Sánchez… - The Journal of …, 2024 - pubs.aip.org
We develop a semi-analytical model for transport in structured catalytic microreactors, where
both reactant and product are compressible fluids. Using lubrication and Fick–Jacobs …

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 …

Generalized Langevin subdiffusion in channels: The bath always wins

EB Postnikov, IM Sokolov - Physical Review E, 2024 - APS
We consider subdiffusive motion, modeled by the generalized Langevin equation in an
equilibrium setting, of tracer particles in channels of indefinite length in the x direction: the …

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 …

[HTML][HTML] Turning catalytically active pores into active pumps

GC Antunes, P Malgaretti, J Harting - The Journal of Chemical Physics, 2023 - pubs.aip.org
We develop a semi-analytical model of self-diffusioosmotic transport in active pores, which
includes advective transport and the inverse chemical reaction that consumes solute. In …

Transport in Catalytic Microchannels

GFC Antunes - 2024 - search.proquest.com
This work focuses on the ways in which the transport of chemically-reactive fluids may be
affected by the presence of confinement. Specifically, we study flow through microchannels …
