As per our previous plan to meet up the aspiration of teachers, students and researchers we are stepping forward to publish another interdisciplinary book covering mainly the different parts of physical and biological sciences. This book is also intended for postgraduate students and young researchers both in Theoretical and Experimental outcomes. We believe that this book will definitely fulfill the expectations of researchers working in related fields in particular. Advancement in applied sciences is a continuous process and it requires high degree of quality and evidence-based research. In this book many recent quality peer reviewed research works and review articles in the related fields are included. Thus the students, research scholars working in the related fields will be definitely benefited. One of the important features of this book is that it is not like a textbook in structure. Again the chapters are written elaborately and such in a lucid manner that even an undergraduate student can grip its benefits. As per the previous book in this series the chapters of this book focus on a wide range of topics from thin films, nanotechnology, microstrip lines, microelectronics to different branches of plant and animal biological sciences mainly food production, SARS CoV 2 to protection of environment, renewable energy and improvement in human health to sustainable protection of our environment in an eco friendly manner and so on. In the very first chapter, a work on structural tuning of BiOCl nano-crystals with PVP modulated visible light stimulated photo catalytic dye degradation process is given. Dispersion analysis of inverted microstrip line in spectral domain and a probe-fed rectangular dielectric resonator antenna (RDRA) with an air gap of rectangular shape by using high frequency
simulation software (HFSS) are included in this book.
