MRI of chemical reactions and processes

MM Britton - Progress in nuclear magnetic resonance spectroscopy, 2017 - Elsevier
As magnetic resonance imaging (MRI) can spatially resolve a wealth of molecular
information available from nuclear magnetic resonance (NMR), it is able to non-invasively …

Mechanism and phenomenology of an oscillating chemical reaction

AF Taylor - Progress in Reaction Kinetics and Mechanism, 2002 - journals.sagepub.com
Chemical reactions, which are far from equilibrium, are capable of displaying oscillations in
species concentrations and hence in colour, electrode potential, pH and/or temperature. The …

Diffusive instabilities and chemical reactions

P Borckmans, G Dewel, A De Wit, E Dulos… - … journal of bifurcation …, 2002 - World Scientific
Diffusive instabilities provide the engine for an ever increasing number of dissipative
structures. In this class autocatalytic chemical systems are prone to generate temporal and …

Nonlinear symmetry breaking induced by third-order dispersion in optical fiber cavities

F Leo, A Mussot, P Kockaert, P Emplit, M Haelterman… - Physical review …, 2013 - APS
We study analytically, numerically, and experimentally the nonlinear symmetry breaking
induced by broken reflection symmetry in an optical fiber system. In particular, we investigate …

Segmentation and somitogenesis derived from phase dynamics in growing oscillatory media

M Kærn, M Menzinger, A Hunding - Journal of theoretical biology, 2000 - Elsevier
The formation of spatially repetitive structures along the growth axis of a developing embryo
is a common theme in developmental biology. Here we apply the novel flow-distributed …

Non-Turing stationary patterns in flow-distributed oscillators with general diffusion and flow rates

RA Satnoianu, M Menzinger - Physical Review E, 2000 - APS
An analytical prediction [P. Andresen et al., Phys. Rev. E 60, 297 (1999)] and its
experimental confirmation [M. Kaern et al., Phys. Rev. E 60, 3471 (1999)] establish a …

Dynamics of pH Oscillators in Continuous Stirred Tanks in Series

C Galanics, I Szalai - ChemPhysChem, 2024 - Wiley Online Library
Complex reaction networks with positive and negative feedback can produce diverse
nonlinear phenomena in open reactors, such as multistability and oscillations. pH oscillators …

A cellular oscillator model for periodic pattern formation

J Jaeger, BC Goodwin - Journal of theoretical biology, 2001 - Elsevier
In this paper, we present a model for pattern formation in developing organisms that is
based on cellular oscillators (CO). An oscillatory process within cells serves as a …

Chemical waves in open flows of active media: their relevance to axial segmentation in biology

M Kærn, M Menzinger, R Satnoianu, A Hunding - Faraday discussions, 2002 - pubs.rsc.org
The boundary forcing of open flows of active media can lead to a variety of spatiotemporal
structures, depending on the local kinetics of the medium and on the characteristics of the …

Diffusive instabilities and spatial patterning from the coupling of reaction–diffusion processes with Stokes flow in complex domains

RA Van Gorder, H Kim, AL Krause - Journal of Fluid Mechanics, 2019 - cambridge.org
We study spatial and spatio-temporal pattern formation emergent from reaction–diffusion–
advection systems formed by considering reaction–diffusion systems coupled to prescribed …
