Turing pattern formation in the Brusselator system with nonlinear diffusion

G Gambino, MC Lombardo, M Sammartino… - Physical Review E …, 2013 - APS
In this work we investigate the effect of density-dependent nonlinear diffusion on pattern
formation in the Brusselator system. Through linear stability analysis of the basic solution we …

Experimental evidence for three universality classes for reaction fronts in disordered flows

S Atis, AK Dubey, D Salin, L Talon, P Le Doussal… - Physical review …, 2015 - APS
Self-sustained reaction fronts in a disordered medium subject to an external flow display self-
affine roughening, pinning, and depinning transitions. We measure spatial and temporal …

Predicting the enhancement of mixing-driven reactions in nonuniform flows using measures of flow topology

NB Engdahl, DA Benson, D Bolster - Physical Review E, 2014 - APS
The ability for reactive constituents to mix is often the key limiting factor for the completion of
reactions across a huge range of scales in a variety of media. In flowing systems …

Crystal Patterning from Aqueous Solutions via Solutal Instabilities

SA McBride, S Atis, AA Pahlavan… - ACS Applied Materials …, 2024 - ACS Publications
Fluid instabilities can be harnessed for facile self-assembly of patterned structures on the
nano-and microscale. Evaporative self-assembly from drops is one simple technique that …

Super-critical and sub-critical bifurcations in a reaction-diffusion Schnakenberg model with linear cross-diffusion

G Gambino, MC Lombardo, S Lupo… - Ricerche di …, 2016 - Springer
In this paper the Turing pattern formation mechanism of a two components reaction-diffusion
system modeling the Schnakenberg chemical reaction is considered. In Ref.(Madzavamuse …

Experimental approaches to universal out-of-equilibrium scaling laws: turbulent liquid crystal and other developments

This is a brief survey of recent experimental studies on out-of-equilibrium scaling laws,
focusing on two prominent situations where nontrivial universality classes have been …

Critical behavior in porous media flow

M Moura, KJ Måløy, R Toussaint - Europhysics Letters, 2017 - iopscience.iop.org
The intermittent burst dynamics during the slow drainage of a porous medium is studied
experimentally. We have shown that this system satisfies a set of conditions known to be true …

Eden model with nonlocal growth rules and kinetic roughening in biological systems

SN Santalla, SC Ferreira - Physical Review E, 2018 - APS
We investigate an off-lattice Eden model where the growth of new cells is performed with a
probability dependent on the availability of resources coming externally towards the growing …

[HTML][HTML] Pinning of reaction–diffusion travelling waves in one-dimensional annular geometry

F Sarnari - Chaos, Solitons & Fractals, 2025 - Elsevier
We analyse the complex dynamics arising in a one-dimensional bistable advection–reaction–
diffusion equation on a bounded annular domain, along with its simplest nontrivial …

Front tracking for quantifying advection-reaction-diffusion

TD Nevins, DH Kelley - Chaos: An Interdisciplinary Journal of …, 2017 - pubs.aip.org
We present an algorithm for measuring the speed and thickness of reaction fronts, and from
those quantities, the diffusivity and the reaction rate of the active chemical species. This front …
