About this Research Topic
Numerous processes in physical chemistry and related sciences take place in a cycle, with consecutive alternations in time. Widely known as oscillatory or oscillating reactions, such processes are explored as nonlinear phenomena, but their potential in various applications became recognized only recently. Self-oscillating gels were developed to be used as components of microdevices (actuators) or to achieve controlled periodic drug delivery. Attempts were made to use oscillating reactions in detecting traces of CO in the air by special sensor technology. Also, a wide spectrum of analytical applications of oscillatory reactions were developed, with unexpected robustness and high sensitivity toward the evaluation of pharmaceutically active compounds. The advantages of fuel cells with electro-catalytic oxidations in oscillating regime were reported too.
Spreading applications of oscillatory reactions to a wide range of different areas was enabled by new experimental techniques for both detection of exotic dynamic states, and control over complex systems far from equilibrium. Also, new insights were achieved in the understanding of physical and chemical mechanisms underlying the extraordinary properties of such processes. However, a conceptual framework is still missing to connect collected knowledge on such exquisite systems, with the engineering design principles necessary for developing useful applications based on them.
The purpose of this Research Topic should be to provide common ground for presenting results of fundamental research and original inventions, using the advantages of spontaneous periodic or aperiodic alternations in directions of reaction processes. The focus should be directed towards the process rather than a system.
Both, original research and reviews are welcome. Original papers should present new ideas with reasonable scientifical background – only essential references should be given here. Reviews must offer a critical overview of the state-of-the-art on fundamentals and applications with special emphasis on the perspectives – an extended list of references would be acceptable in this case. In both cases, relation to the Research Topic should be clearly given in the Abstract. We encourage the submission of manuscripts dedicated to Topics including, but not limited, to the following:
• Catalytic process enhancement in the regime of oscillatory reaction
• Electro-catalytic oxidations with spontaneous oscillations in electrode coverage
• Coupling of oscillatory reactions with smart materials
• Chemical chaos in the encryption process
• Analytical applications of oscillatory reactions
Keywords: oscillatory reaction, oscillating reaction, nonlinear dynamics, chemical chaos, self-oscillating gel
Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
