Nanomaterials and their Fascinating Attributes

Nano represent very small thing which has diverse applications and high potency that guiding to industrial and technological development.

Materials of nano size show remarkable physical and chemical properties due to several factors including the rise in surface area compared to volume which takes place as particles get smaller.

Nanotechnology finds its applications in many areas such as novel foodstuffs, medical equipments, chemical coatings, human health testing kits, security system’s sensor, water purification items for manned space craft, displays for hand-held computer games, and cinema screens. Nanotechnology is likely to impart an impact on almost every industry. Recently nanotechnology has become known as the science of every tiny thing, more particularly, 'nano'. Nanotechnology is a catch-all expression for resources and tools that function at the nanoscale.

Nanotechnology is a diverse science that has spread its applications in fields such as colloidal science, device physics and supra molecular chemistry. Being a subject of key interest, it was thought out to present recent development in nanotechnology in the form of a book to the scientific community.

There are six chapters in this book. In the first chapter, the recent development of nanotechnology in many applications such as energy/power, medicine/healthcare, water purification, biotechnology, electronics, sporting goods, environmental issues, defense/security, and textile/fabrics is summarized. Chapter two reviews the latest developments in the area of nanocomposites with reference to nanoclays, nanofibers and nanotubes. The classification, characterization and applications of various types of nanocomposites have been discussed in aerospace industry. It also highlighted the applications of nanocomposites in relaunch vehicles, space ladders, ablatives, internal motor casing and nano modified carbon/carbon composites. In third chapter, use and potential applications of nano materials, organic semiconductor complexes and composites sensors, organic field effect transistors, thin-film field effect transistors, temperature sensitive field-effect transistor, solar cells, and light-emitting diodes have been summarized. Fourth chapter describe nanotechnology, nanomaterials, nanocomposites, their importance, synthesis and characterization of nanocomposites. Fifth chapter describe synthesis of nanoparticles of various compositions, their exciting properties and size, and morphologies for a wide range of applications. Chapter six deals with DFT study of nanoparticles using run type of Frequencies in ADF-Molecule interface.

We deem that this book will convey the savor of the nanotechnology properly and illustrate that study on nanomaterials is emerging to be of key interest. We intently anticipate that this book will be beneficial for students, teachers and practitioners.
