Diffusion-controlled reactions: An overview

DS Grebenkov - Molecules, 2023 - mdpi.com
We review the milestones in the century-long development of the theory of diffusion-
controlled reactions. Starting from the seminal work by von Smoluchowski, who recognized …

Comprehensive reactive receiver modeling for diffusive molecular communication systems: Reversible binding, molecule degradation, and finite number of receptors

A Ahmadzadeh, H Arjmandi… - IEEE transactions on …, 2016 - ieeexplore.ieee.org
This paper studies the problem of receiver modeling in molecular communication systems.
We consider the diffusive molecular communication channel between a transmitter nano …

First passage statistics for the capture of a Brownian particle by a structured spherical target with multiple surface traps

AE Lindsay, AJ Bernoff, MJ Ward - Multiscale Modeling & Simulation, 2017 - SIAM
We study the first passage time problem for a diffusing molecule in an enclosed region to hit
a small spherical target whose surface contains many small absorbing traps. This study is …

Spectral theory of imperfect diffusion-controlled reactions on heterogeneous catalytic surfaces

DS Grebenkov - The Journal of Chemical Physics, 2019 - pubs.aip.org
We propose a general theoretical description of chemical reactions occurring on a catalytic
surface with heterogeneous reactivity. The propagator of a diffusion-reaction process with …

On the applicability of entropy potentials in transport problems

AM Berezhkovskii, SM Bezrukov - The European Physical Journal Special …, 2014 - Springer
Transport in confined structures of varying geometry has become the subject of growing
attention in recent years since such structures are ubiquitous in biology and technology. In …

Diffusion-controlled reactions with non-Markovian binding/unbinding kinetics

DS Grebenkov - The Journal of Chemical Physics, 2023 - pubs.aip.org
We develop a theory of reversible diffusion-controlled reactions with generalized
binding/unbinding kinetics. In this framework, a diffusing particle can bind to the reactive …

Probability distribution of the boundary local time of reflected Brownian motion in Euclidean domains

DS Grebenkov - Physical Review E, 2019 - APS
How long does a diffusing molecule spend in a close vicinity of a confining boundary or a
catalytic surface? This quantity is determined by the boundary local time, which plays thus a …

Short-time diffusive fluxes over membrane receptors yields the direction of a signalling source

AE Lindsay, AJ Bernoff… - Royal Society Open …, 2023 - royalsocietypublishing.org
An essential ability of many cell types is to detect stimuli in the form of shallow chemical
gradients. Such cues may indicate the direction that new growth should occur, or the …

Sound scattering by a lattice of resonant inclusions in a soft medium

A Skvortsov, I MacGillivray, GS Sharma… - Physical Review E, 2019 - APS
We present a generalized analytical model to investigate acoustic scattering by a lattice of
voids of arbitrary shape in a viscoelastic matrix. To this end, we represent the lattice of voids …

First-passage times to anisotropic partially reactive targets

A Chaigneau, DS Grebenkov - Physical Review E, 2022 - APS
We investigate restricted diffusion in a bounded domain towards a small partially reactive
target in three-and higher-dimensional spaces. We propose a simple explicit approximation …
