Here is a compilation of the research being done by scientists from various disciplines of chemistry at universities across the globe. This new volume provides a wealth of practical experience and research on new methodologies and important applications in chemical science. It also includes presentations on small-scale new drug design related projects that have potential applications in several disciplines of chemistry and in drug development. In this book, contributions range from new methods to novel applications of existing methods to enhance understanding of the material and/or structural behavior of new and advanced systems.Topics cover computational methods in chemical sciences and electrochemical investigations; studies of some of physico-chemical properties of several important novel macrocyclic ligands; the use of lanthanide-ions doped nanomaterials; quantitative estimation of heavy metals, a sustainable, efficient and green promoter for the synthesis of some heterocyclic compounds; and much more.

This book describes the solar power and piezoelectric based energy optimization and appliances control. The increase in energy consumption of portable electronic devices and the concept of harvesting renewable energy in human surrounding arouses a renewed interest. This book focuses on one of such advanced methods of energy harvesting using solar cell and piezoelectric material. Piezoelectric materials can be used as mechanisms to transfer mechanical energy, usually ambient vibration, into electrical energy that can be stored and used to power other devices. A solar tracker is used in various systems for the improvement of harnessing of solar radiation. The problem posed is the implementation of a system which is capable of enhancing production of power by 30-40%. The control circuit is implemented by the microcontroller. The control circuit then positions the motor that is used to orient the solar panel optimally.
