Summary: Materials are the essential part of our daily life and civilizations have been known by the materials they introduced. As the science progressed, scientists used the different combinations of material to enhance their properties to cope with new challenges and requirements. Alloys are also the combination of different materials specifically of metals. In early ages Iron and their alloys were used in the manufacturing heavy machineries. Gradually elements of lighter weight replaced the ferrous material like Alloys of Mg and Al. The main focus of this book will be on Aluminum Alloys...

Sulfonamides are the commonly used antibiotics, which are used in the combination with other antibiotics to enhance their effect. They are absorbed in the intestine and are widely distributed into the tissues. Sulfonamides inhibit the growth of bacteria by reverse inhibition and block the cycle of folic acid synthesis while they are effective against only those bacteria which produce folic acid intracellular. This book discusses about the synthesis of sulfonamides their characterization with modern instruments and their importance. The antibacterial activity which increases their importance...
