Scroll waves in the Belousov–Zhabotinsky reaction: exploitation of O2-effect on the ferroin-catalysed system
Literature Information
The inhibiting effect of dissolved oxygen on wave propagation in the ferroin-catalysed Belousov–Zhabotinsky (BZ) reaction is exploited to obtain three-dimensional scroll waves experimentally in this system. The development of the scrolls is monitored by imaging the wave evolution via a video camera and image acquisition software. Solutions for which the initial waves are initiated under an atmosphere of pure oxygen have a subexcitable or inhibited layer of typically 1 mm depth. Once the O2 is replaced by N2, this layer regains excitability and a scroll wave structure can develop. For waves initiated under air, the depth of the inhibited layer is less and scroll waves do not develop. A simple extension of the ZBKE model for the ferroin system is proposed and shown to predict the oxygen inhibition in reasonable agreement with experiment.

Physical Chemistry Chemical Physics

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
