Book Synopsis Thermodynamic and Transport Properties in Carbon Nanostructures by : Gaurav Arora
Download or read book Thermodynamic and Transport Properties in Carbon Nanostructures written by Gaurav Arora and published by . This book was released on 2007 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: In addition to the specific analysis of N2/O2 separations using nanotubes, the approach and the simulation programs developed in this research were also extended to understand the mechanism for the higher permeation rates of oxygen relative to nitrogen in nanoporous carbon membranes (NPCs) that has been reported in experiments. The key mechanism for such large differences in the permeation rates has not been understood as nitrogen and oxygen have very similar molecular sizes and interaction energetics.

Book Synopsis Nano-scale Heat Transfer in Nanostructures by : Jihong Al-Ghalith
Download or read book Nano-scale Heat Transfer in Nanostructures written by Jihong Al-Ghalith and published by Springer. This book was released on 2018-03-06 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces modern atomistic techniques for predicting heat transfer in nanostructures, and discusses the applications of these techniques on three modern topics. The study of heat transport in screw-dislocated nanowires with low thermal conductivity in their bulk form represents the knowledge base needed for engineering thermal transport in advanced thermoelectric and electronic materials, and suggests a new route to lower thermal conductivity that could promote thermoelectricity. The study of high-temperature coating composite materials facilitates the understanding of the role played by composition and structural characterization, which is difficult to approach via experiments. And the understanding of the impact of deformations, such as bending and collapsing on thermal transport along carbon nanotubes, is important as carbon nanotubes, due to their exceptional thermal and mechanical properties, are excellent material candidates in a variety of applications, including thermal interface materials, thermal switches and composite materials.

Download or read book Mechanical and Transport Properties of Carbon Nanotube Systems written by and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanical and transport properties of carbon nanotube systems are studied by large-scale ab initio, tight-binding and classical molecular dynamics simulations. The ultimate strength of carbon nanotubes is investigated theoretically. While the formation energy of strain-induced topological defects determines the thermodynamic limits of the elastic response and of mechanical resistance to applied tension, it is found that the activation barriers for the formation of such defects are much larger than estimated previously. The theoretical results indicate a substantially greater resilience and strength, and show that the ultimate strength limit of carbon nanotubes has yet to be reached experimentally. Carbon nanotubes are indeed the strongest material known. The electronic transport in a new type of carbon nanotube material: carbon nanotube-metal cluster assembly is investigated for gas absorption. For an Al cluster attached to a metallic nanotube, we have observed that its electrical response dramatically changes upon NH3 adsorption onto the metal cluster. For a semiconducting nanotube-Al cluster assembly, the same gas adsorption enhances the system's conductivity. The results of our ab initio simulations explain the observed behavior in terms of interactions between the molecular species and the nanotube-cluster system, where successive charge transfers between the components tailor the electronic and transport properties. Carbon nanotubemetal cluster assemblies could be a new type of nanotube-based chemical/biological sensors.
Book Synopsis Nanoscale Thermoelectrics by : Xiaodong Wang
Download or read book Nanoscale Thermoelectrics written by Xiaodong Wang and published by Springer Science & Business Media. This book was released on 2013-11-18 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the efficient utilization of energy resources and the minimization of environmental damage, thermoelectric materials can play an important role by converting waste heat into electricity directly. Nanostructured thermoelectric materials have received much attention recently due to the potential for enhanced properties associated with size effects and quantum confinement. Nanoscale Thermoelectrics describes the theory underlying these phenomena, as well as various thermoelectric materials and nanostructures such as carbon nanotubes, SiGe nanowires, and graphene nanoribbons. Chapters written by leading scientists throughout the world are intended to create a fundamental bridge between thermoelectrics and nanotechnology, and to stimulate readers' interest in developing new types of thermoelectric materials and devices for power generation and other applications. Nanoscale Thermoelectrics is both a comprehensive introduction to the field and a guide to further research, and can be recommended for Physics, Electrical Engineering, and Materials Science departments.
Book Synopsis Thermal Transport in Carbon-Based Nanomaterials by : Gang Zhang
Download or read book Thermal Transport in Carbon-Based Nanomaterials written by Gang Zhang and published by Elsevier. This book was released on 2017-06-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thermal Transport in Carbon-Based Nanomaterials describes the thermal properties of various carbon nanomaterials and then examines their applications in thermal management and renewable energy. Carbon nanomaterials include: one-dimensional (1D) structures, like nanotubes; two-dimensional (2D) crystal lattice with only one-atom-thick planar sheets, like graphenes; composites based on carbon nanotube or graphene, and diamond nanowires and thin films. In the past two decades, rapid developments in the synthesis and processing of carbon-based nanomaterials have created a great desire among scientists to gain a greater understanding of thermal transport in these materials. Thermal properties in nanomaterials differ significantly from those in bulk materials because the characteristic length scales associated with the heat carriers, phonons, are comparable to the characteristic length. Carbon nanomaterials with high thermal conductivity can be applied in heat dissipation. This looks set to make a significant impact on human life and, with numerous commercial developments emerging, will become a major academic topic over the coming years. This authoritative and comprehensive book will be of great use to both the existing scientific community in this field, as well as for those who wish to enter it. Includes coverage of the most important and commonly adopted computational and experimental methods to analyze thermal properties in carbon nanomaterials Contains information about the growth of carbon nanomaterials, their thermal properties, and strategies to control thermal properties and applications, allowing readers to assess how to use each material most efficiently Offers a comprehensive overview of the theoretical background behind thermal transport in carbon nanomaterials

Download or read book Controlling Diameters and Transport Properties of Carbon Nanotubes by Synthesis and Chemical Modification written by Lei An and published by . This book was released on 2005 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second thrust focuses on a simple chemical method to selectively react diazonium reagents with metallic carbon nanotubes in nanotube thin film devices while keeping the semiconducting nanotubes intact. Thus, semiconducting-only carbon nanotube thin film devices can be fabricated using this method. It has been proved that the concentration of the diazonium reagents play a crucial role in the reaction process. Excessive amounts of diazonium reagents will indiscriminately react with both metallic and semiconducting nanotubes, which will significantly degrade the performance of the nanotube thin film devices. In addition, the diameters of the nanotubes in the thin films are crucial to determining the reactivity of the nanotubes, as the diazonium reagents react more readily with smaller diameter nanotubes than with larger diameter nanotubes.
