This book comprehensively discusses the methods and practices for evaluating geochemical processes in aquifer groundwater. Possible occurrence and mechanisms of rock-water interaction, trace metal mobilization, thermodynamic explanation, actions of aquifer CO2, pollution sources, geogenic influencing factors, and isotope dilution methods are the primary areas of focus. These water quality variables are analyzed using a variety of logical/theoretical explanations, statistical techniques, and experimental procedures to determine the suitability of groundwater for drinking, irrigation, and other industrial purposes. The work is an important addition to hydrogeochemical literature since many existing indexing methods for the assessment of water quality are very old and have some degree of limitation. The book will be a useful resource for students, lecturers, and researchers working in the fields of hydrogeochemistry, hydrology, water pollution, and groundwater quality. .

Nanomaterials have recently garnered significant attention and practical importance for heterogeneous electrocatalysis. This book presents recent developments in the design, synthesis, and characterisation of nanostructured electrocatalytic materials, with a focus on applications to energy and wastewater treatment. Electrocatalytic nanomaterials can enhance process efficiency and sustainability, thus providing innovative solutions for a wide array of areas such as sustainable energy production, conversion, and wastewater treatment. Readers will gain insights into the latest breakthroughs in electrocatalysis and the activity of nanomaterials in energy conversion applications, e.g., fuel cells, hydrogen production, water splitting, and electro/photocatalytic water splitting, as well as for wastewater treatment. The book explores the development of advanced electrocatalysts, particularly hybrid materials.
