Download or read book Single-Walled Carbon Nanotubes written by Yan Li and published by Springer. This book was released on 2019-05-16 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Download or read book Mechanism of Synthesis of Ultra-Long Single Wall Carbon Nanotubes in Arc Discharge Plasma written by and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In this project fundamental issues related to synthesis of single wall carbon nanotubes (SWNTs), which is relationship between plasma parameters and SWNT characteristics were investigated. Given that among plasma-based techniques arc discharge stands out as very advantageous in several ways (fewer defects, high flexibility, longer lifetime) this techniques warrants attention from the plasma physics and plasma technology standpoint. Both experimental and theoretical investigations of the plasma and SWNTs synthesis were conducted. Experimental efforts focused on plasma diagnostics, measurements of nanostructures parameters, and nanoparticle characterization. Theoretical efforts focused to focus on multi-dimensional modeling of the arc discharge and single wall nanotube synthesis in arc plasmas. It was demonstrated in experiment and theoretically that controlling plasma parameters can affect nanostucture synthesis altering SWNT properties (length and diameter) and leading to synthesis of new structures such as a few-layer graphene. Among clearly identified parameters affecting synthesis are magnetic and electric fields. Knowledge of the plasma parameters and discharge characteristics is crucial for ability to control synthesis process by virtue of both magnetic and electric fields. New graduate course on plasma engineering was introduced into curriculum. 3 undergraduate students were attracted to the project and 3 graduate students (two are female) were involved in the project. Undergraduate student from Historically Black University was attracted and participated in the project during Summer 2010.

This book was released on 2006 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes (CNT) constitute a new class of materials discovered in 1991 by Sumio Iijima that present unusual mechanical, electrical and thermal properties. Chemical Vapor Deposition (CVD) is the most promising synthesis route for producing large quantities of carbon nanotubes at a low cost. The first part of this thesis focuses on surface synthesis of high purity aligned carbon nanotubes using the CVD technique. High purity single wall and multi wall carbon nanotubes were grown using different substrates and catalysts. The substrates include non porous silicon substrates, porous silicon substrates, stainless steel substrates, stainless steel wires, and silicon cantilevers. The catalysts include molybdenum supported cobalt and alumina supported iron liquid catalysts, and iron and molybdenum catalysts deposited using e-beam evaporation and photolithographic techniques. Vertically aligned single wall and multi wall carbon nanotube forests were grown using the Easy Tube nanofurnace based on the CVD mechanism. The maximum length of the nanotubes grown was almost one millimeter and the diameters ranged from 1 to 100 nanometers. The nanotubes have a large surface area to volume ratio and a high electrochemical sensitivity. These properties may be useful for many applications such as reinforcing polymer composites, drug delivery, biomedical implants, neural imaging, development of biosensors for cancer detection, and other medical applications such as sensing and treating disorders like Epilepsy, Parkinson's disease, and Alzheimer's disease. Since nanotubes are proposed to be used for many biomedical applications, it becomes very important to understand the hazards of nanotubes and nanotechnology. Hence this thesis also presents a short overview of the toxicity of nanotubes. Carbon nanotube and nanofiber reinforced polymer composites have received tremendous amount of attention due to their interesting mechanical, electrical and thermal properties and potential applications. These composites potentially offer high stiffness, high strength, low electrical resistivity, dimensional stability, and light weight. Harnessing the unique physical properties of carbon nanostructures in materials applications has yet to be fully realized. The second part of this thesis mainly deals with improving the properties of composites using carbon nanofibers as fillers in an epoxy matrix. The single most important factor influencing use of carbon nanofibers as reinforcing fibers in polymer composites is their ability to effectively transfer the applied load in the matrix. The effective utilization of nanofibers in composites for structural applications depends strongly on the ability to disperse the nanofibers homogeneously in the matrix without damaging them. To be successfully used for enhancing the properties of composites, good interfacial bonding is required to achieve load transfer across the nanofiber-polymer interface. Hence, two main problems which arise in improving the properties are poor dispersion of the fibers in the composite and weak bonding between fibers and the matrix. These problems are attacked in this thesis by mechanical and chemical means. Solvent free functionalization, controlled sonication, high speed shear mixing at elevated temperatures, and high pressure casting are used to exfoliate the nanofibers in the epoxy. Pyrograf and CleanTech carbon nanofibers, which are similar to large diameter multi-wall carbon nanotubes, were used as filler materials in processing of composites. Incorporating 5 percentage by weight Pyrograf carbon nanofibers resulted in improvement of stiffness of the composite by about 45 percentage by weight and incorporating 5 percentage by weight CleanTech carbon nanofibers resulted in improvement of stiffness of the composite by 20 percentage by weight when compared to plain epoxy with out any nanofibers.

This book was released on 2006-05-03 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is about 15 years that the carbon nanotubes have been discovered by Sumio Iijima in a transmission electron microscope. Since that time, these long hollow cylindrical carbon molecules have revealed being remarkable nanostructures for several aspects. They are composed of just one element, Carbon, and are easily produced by several techniques. A nanotube can bend easily but still is very robust. The nanotubes can be manipulated and contacted to external electrodes. Their diameter is in the nanometer range, whereas their length may exceed several micrometers, if not several millimeters. In diameter, the nanotubes behave like molecules with quantized energy levels, while in length, they behave like a crystal with a continuous distribution of momenta. Depending on its exact atomic structure, a single-wall nanotube –that is to say a nanotube composed of just one rolled-up graphene sheet– may be either a metal or a semiconductor. The nanotubes can carry a large electric current, they are also good thermal conductors. It is not surprising, then, that many applications have been proposed for the nanotubes. At the time of writing, one of their most promising applications is their ability to emit electrons when subjected to an external electric field. Carbon nanotubes can do so in normal vacuum conditions with a reasonable voltage threshold, which make them suitable for cold-cathode devices.

Download or read book Perspective of Carbon Nanotubes written by Hosam El-Din Saleh and published by BoD – Books on Demand. This book was released on 2019-12-11 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon nanotubes belong to new nanomaterials and have been known for almost 20 years, but their history is somewhat lengthier. They have been identified as promising candidates for various applications.High-temperature preparation techniques are conventional techniques for the synthesis of carbon nanotubes using arc discharge or laser ablation, but today these methods are being replaced by low-temperature vapor deposition techniques, since orientation, alignment, nanotube length, diameter, purity, and density of carbon nanotubes can be precisely controlled. The synthesis of carbon nanotubes by chemical vapor deposition on catalyst arrays leads to nanotube models grown from specific sites on surfaces. The controlled synthesis of nanotubes opens up interesting possibilities in nanoscience and nanotechnologies, including electrical, mechanical and electromechanical properties and devices, chemical functionalization, surface chemistry and photochemistry, molecular sensors, and interfacing with moderate biological systems.Carbon nanotubes are used in many applications due to their unique electrical, mechanical, optical, thermal, and other properties. Conductive and high-strength composite materials, energy saving and energy conversion devices, sensors, visualization of field emissions and sources of radiation, means for storing hydrogen, and nanoscale semiconductor devices, probes, and interconnections are some of the many applications of carbon nanotubes.
