In this book up-to-date and includes latest research areas like synthesis nano transition metal ferrites by using gel method and charcterized by XRD and SEM. The results are presented. This method leads to form fully crystalline particles even at high annealed temperatures. Further, in this book we can present the synthesis of 1,4-dihydro pyridines by using copper ferrite as nano catalyst.The synthetic route and procedure was presented and characterized by spectral dat and results were presented. It is very convenient method to synthesize 1,4-dihydro pyridines and also copper ferrite act as a reusable catalyst. The above work is very helpful to young researchers,who is interested the area of nanotechnology and organic synthesis.
