This book was released on 1998 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly-oriented, multi-walled carbon nanotubes were grown on polished polycrystalline and single crystal nickel substrates by plasma enhanced hot filament chemical vapor deposition at temperatures below 666"C. The carbon nanotubes range from 10 to 500 nm in diameter and 0.1 to 50 pm in length depending on growth conditions. Acetylene is used as the carbon source for the growth of the carbon nanotubes and ammonia is used for dilution gas and catalysis. The plasma intensity, acetylene to ammonia gas ratio and their flow rates, etc. affect the diameters and uniformity of the carbon nanotubes. In summary, we synthesized large-area highly-oriented carbon nanotubes at temperatures below 666C by plasma-enhanced hot filament chemical vapor deposition. Acetylene gas is used to provide carbon for nanotube growth and ammonia gas is used for dilution and catalysis. Plasma intensity is critical in determining the nanotube aspect ratios (diameter and length), and range of both site and height distributions within a given film.

Book excerpt: Nanomaterials are destined to become a discipline as distinct and important as polymers are in chemistry! With the realization that the structure of molecules such as C60 and C70 followed simple geometric principles, it became clear that a great variety of hollow, closed carbon structures, including nanotubes, could be made along the same principles. The modern nanotube can be thought of as the ultimate fiber formed of perfectly closed, seamless shells having unique features, such as mechanical and electronic properties that are very sensitive to its geometry and its dimensions. The nanotube has many uses:

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Catalyst patterns for the directed assembly of CNTs were prepared by electron-beam lithography (EBL). Experiments were performed that demonstrated the feasibility of using lithographic methods to achieve directed assembly of carbon nanotubes for the manufacture of CNT devices. Experiments focusing on growth interruption and regrowth of CNTs were conducted to investigate methods of introducing tailored branching points into carbon nanotubes during the growth process. These experiments clearly demonstrate that growth interruption increases the occurrence of CNT branching. An analysis of the relationships between CNT diameter, branching points, and the number of growth steps was conducted.

Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes (CNTs), discovered in 1991, have been a subject of intensive research for a wide range of applications. In the past decades, although carbon nanotubes have undergone massive research, considering the success of silicon, it has, nonetheless, been difficult to appreciate the potential influence of carbon nanotubes in current technology. The main objective of this book is therefore to give a wide variety of possible applications of carbon nanotubes in many industries related to electron device technology. This should allow the user to better appreciate the potential of these innovating nanometer sized materials. Readers of this book should have a good background on electron devices and semiconductor device physics as this book presents excellent results on possible device applications of carbon nanotubes. This book begins with an analysis on fabrication techniques, followed by a study on current models, and it presents a significant amount of work on different devices and applications available to current technology.

Available in PDF, EPUB and Kindle. Book excerpt: The widespread and increasing use of carbon nanotubes in scientific and engineering research and their incorporation into manufactured goods has urged an assessment of the risks and hazards associated with exposure to them. The field of nanotoxicology studies the toxicology of nanoparticles such as carbon nanotubes and has become a major growth area aimed towards risk assessment of nanoparticles. Compiled by a team of leading experts at the forefront of research, this is the first book dedicated to the toxicology of carbon nanotubes. It provides state-of-the-science information on how and why they are so potentially dangerous if breathed in, including their similarities to asbestos. The book examines various aspects of carbon nanotubes, from their manufacture and aerodynamic behaviour to their effects at molecular level in the lungs. It is invaluable to the many groups involved with research in this area, as well as to regulators and risk assessors.

Book excerpt: The unique electronic, mechanical and physical properties led Carbon nanotubes (CNTs) to be potential candidate for field emitter, hydrogen storage, sensors, nano electronic devices, nano electromechanical systems, polymer composites. In order to make them in the industrial scale we need large quantity production of CNTs with low cost. The present thesis work deals with the preparation of CNTs by pyrolysis method from xylene and further studies on the grown CNTs. Magnetic characterization of CNTs has been done using SQUID. The interaction of CNTs with the microwave irradiation is studied and it was found for the first time that there is light emission from the CNTs apart from direct electric field. In this process we also observed that the static charge develops on the CNTs. A composite of CNTs/DNA has been prepared with varying CNT content and the electrical conductivity measurements have been done. The first chapter of the thesis provides an introduction to carbon family. Carbon nanotubes, which are potential candidates from carbon family, is a growing field for research in science and technology. A glimpse of various methods of preparation of CNTs like arc-discharge, laser ablation, chemical vapour deposition (CVD), hot-filament CVD, plasma enhanced chemical vapor deposition (PECVD), electron cyclotron resonance (ECR PECVD), high-pressure catalytic decomposition of carbon monoxide (HiPCO), pyrolysis are discussed. Some applications of CNTs are also included in this chapter. The second chapter deals with the experimental techniques employed for the preparation of CNTs and their characteristics studied by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD) and Raman Spectroscopy (RS). The preparation of CNTs from xylene as carbon source and ferrocene as catalyst in pyrolysis method is described in detail. Well aligned CNTs with a length of several tens of micrometers and diameter of 40 to 80 nanometers were obtained a.

This book was released on 2013-03-08 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was begun after three of the present authors gave a series of in vited talks on the subject of the structure and properties of carbon filaments. This was at a conference on the subject of optical obscuration, for which submicrometer diameter filaments with high length-to-diameter ratios have potential applications. The audience response to these talks illustrated the need of just one scientific community for a broader knowledge of the struc ture and properties of these interesting materials. Following the conference it was decided to expand the material presented in the conference proceedings. The aim was to include in a single volume a description of the physical properties of carbon fibers and filaments. The research papers on this topic are spread widely in the literature and are found in a broad assortment of physics, chemistry, materials science and engineering and polymer science journals and conference proceedings (some of which are obscure). Accordingly, our goal was to produce a book on the subject which would enable students and other researchers working in the field to gain an overview of the subject up to about 1987.
