Nanotechnology is a multidisciplinary field and has achieved breakthroughs in bioengineering, molecular biology, diagnostics, and therapeutics. Nanotechnology is the study of the control of matter on an atomic and molecular scale. Generally nanotechnology deals with structures of the size 100 nanometers or smaller, and involves developing materials or devices within that size. Nanotechnology is very diverse, ranging from novel extensions of conventional device physics, to completely new approaches based upon molecular self-assembly, to developing new materials with dimensions on the nanoscale, even to speculation on whether we can directly control matter on the atomic scale. There has been m...
Nanotechnology is the study of the controlling of matter on an atomic and molecular scale and is very diverse, ranging from extensions of conventional device physics to completely new approaches based upon molecular self-assembly, from developing new materials with dimensions on the nanoscale to investigating whether we can directly control matter on the atomic scale. This book gathers and presents data on nanotechnology including the growth of zinc oxide (ZnO) nanostructured films by means of excimer laser ablation; modelling defective carbon nanotubes by molecular mechanics; advances in surface functionalisation of carbon nanotubes; the catalytic, optical, and thermodynamic properties of amorphous TiO2 nanoparticles; and, others.
This volume includes five chapters that describe recent advances in nanotechnology research.

In the last few decades, Spectroscopy and its application dramatically diverted science in the direction of brand new era. This book reports on recent progress in spectroscopic technologies, theory and applications of advanced spectroscopy. In this book, we (INTECH publisher, editor and authors) have invested a lot of effort to include 20 most advanced spectroscopy chapters. We would like to invite all spectroscopy scientists to read and share the knowledge and contents of this book. The textbook is written by international scientists with expertise in Chemistry, Biochemistry, Physics, Biology and Nanotechnology many of which are active in research. We hope that the textbook will enhance the knowledge of scientists in the complexities of some spectroscopic approaches; it will stimulate both professionals and students to dedicate part of their future research in understanding relevant mechanisms and applications of chemistry, physics and material sciences.

This is the first volume of a four volume set of the Comprehensive Guide for Nanocoatings Technology. Nanocoatings are a kind of thin film with at least one nanometric dimension. The main difference between nano and ordinary coatings is in their structure and properties. To recognize these differences, it is required to study the properties and structure of nanocoatings. The properties of every substance are controlled by their constituents. In this regard, properties of coatings depend on the constituent grains and particles. The chemical, physical, and mechanical properties of nanocoatings including their electrical resistance, permeability, corrosion and abrasion resistance, and magnetic properties, which are a function of structure and particle size of coatings. It is evident that use of these features creates many potential applications. This volume mainly discusses the deposition and growth mechanism of nanocoatings. There are 16 chapters in this volume; each one includes examples of these interesting materials, supported by appropriate figures for better clarification.
