LCs are self-organized anisotropic fluids that are thermodynamically located between the isotropic liquid and the crystalline phase, exhibiting the fluidity of liquids as well as the long-range lattice order that can only be found in crystalline solids. The addition of nanomaterials to a LC material produces a composite or colloidal dispersion and results into a revolutionary change in their applications. This book will discuss the remarkable performances of nano-particle aided liquid crystals in metamaterials, photonics, functionalized polymer fibres, sensing, and medical diagnostics.

Recent advances in nanotechnology has led the nanomaterials into the realm of sensing applications. This descriptive book utilizes a multi-disciplinary approach to provide extensive information about sensors and elucidates the impact of nanotechnology on development of chemical and biosensors for diversified applications. The main focus of this book is not only the inclusion of various research works, which have already been reported in literature, but also to make a potential conclusion about the mechanism behind this. This book will serve as an invaluable tool for both frontline researchers and academicians to work towards the future development of nanotechnology in sensing devices.

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.
