The Third Edition of this book has been comprehensively revised in a coherent style to impart fundamental principles and useful applications of chemistry in engineering and technology. It provides extensive explanation of all five modules―Electrochemistry and Battery Technology, Corrosion and Metal Finishing, Fuels and Solar Energy, Polymers, Water Technology and Nanomaterials―with good emphasis on topics of interest in engineering. The newly added material to this edition certainly builds up the information as well as strengthens the text further
