The book introduces
the oscillatory reaction and pattern formation in the Belousov-Zhabotinsky (BZ) reaction that became model for investigating a
wide range of intriguing pattern formations in chemical systems. So many
modifications in classic version of BZ reaction have been carried out in
various experimental conditions that demonstrate rich varieties of temporal
oscillations and spatio-temporal patterns in non- equilibrium conditions.
Mixed-mode versions of BZ reactions, which comprise a pair of organic
substrates or dual metal catalysts, have displayed very complex oscillating
behaviours and novel space-time patterns during reaction processes. These
characteristic spatio-temporal properties of
BZ reactions have attracted increasing attention of the scientific community in
recent years because of its comparable periodic structures in electrochemical
systems, polymerization processes, and
non-equilibrium crystallization phenomena. Instead, non-equilibrium
crystallization phenomena which lead to development of novel crystal
morphologies in constraint of thermodynamic equilibrium conditions have been
investigated and are said to be stationary periodic structures. Efforts have
continued to analyze insight mechanisms and roles of reaction-diffusion
mechanism and self-organization in the growth of such periodic crystal
patterns. In this book, non-equilibrium crystallization phenomena, leading to
growth of some novel crystal patterns in dual organic substrate modes of
oscillatory BZ reactions have been discussed. Efforts have been made to find
out experimental parameters where transitions of the spherulitic crystal
patterns take place. The book provides the scientific community and entrepreneurs with
a thorough understanding and knowledge of the growth and form of branched
crystal pattern in reaction-diffusion system
and their morphological transition.
