Nanoparticle synthesis techniques have got more importance than the bulk preparation methods due to their unique and promising applications. The applications of nanomaterials have been enormous, which not only encompasses a single discipline but it stretches across the whole spectrum of science right from agricultural science to space technology. In the book entitled "Multiferroic nature of LaCo-titanate based nanoparticles" an attempt is made to synthesize novel Co and La doped lead titanate nanoparticles and to understand the crystal structure and the optical, dielectric, and ferroelectric properties of modified lead titanate nanoparticles.
