It took five long years to write this book. Spare me 30 seconds for persuading you to read this book! I am a Scientific writer and a material scientist. This book adopted the simplest method of preparation of nano materials called solution combustion synthesis. Anybody can start adopting this method of preparation of nano materials. The very basics are elaborated in this book. It is a fragile and swift method that does not cost you very expensive or sophisticated gadgets for the preparation. You can start preparing any metal oxide nano particles with just an electric stove, beaker and very few chemicals: a metal nitrate and a fuel (urea, glycine, etc.,). This book also introduce zirconia as a potential photoluminescence material and also as a thermoluminescence dosimetric material.
