Photophysics of Carbon Nanotubes Interfaced with Organic and Inorganic Materials describes physical, optical and spectroscopic properties of the emerging class of nanocomposites formed from carbon nanotubes (CNTs) interfacing with organic and inorganic materials. The three main chapters detail novel trends in photophysics related to the interaction of light with various carbon nanotube composites from relatively simple CNT/small molecule assemblies to complex hybrids such as CNT/Si and CNT/DNA nanostructures. The latest experimental results are followed up with detailed discussions and scientific and technological perspectives to provide a through coverage of major topics including: -Light harvesting, energy conversion, photoinduced charge separation and transport in CNT based nanohybrids -CNT/polymer composites exhibiting photoactuation; and -Optical spectroscopy and structure of CNT/DNA complexes. Including original data and a short review of recent research, Photophysics of Carbon Nanotubes Interfaced with Organic and Inorganic Materials makes this emerging field of photophysics and its applications available to academics and professionals working with carbon nanotube composites in fundamental and applied fields

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.

Carbon nanotubes are one of the most intriguing new materials with extraordinary properties being discovered in the last decade. The unique structure of carbon nanotubes provides nanotubes with extraordinary mechanical and electrical properties. The outstanding properties that these materials possess have opened new interesting researches areas in nanoscience and nanotechnology. Although nanotubes are very promising in a wide variety of fields, application of individual nanotubes for large scale production has been limited. The main roadblocks, which hinder its use, are limited understanding of its synthesis and electrical properties which lead to difficulty in structure control, existence of impurities, and poor processability. This book makes an attempt to provide indepth study and analysis of various synthesis methods, processing techniques and characterization of carbon nanotubes that will lead to the increased applications of carbon nanotubes.

Due to their rare combination of high chemical stability, exceptional optical and electrical properties, high surface-to-volume ratio, and high aspect ratio, carbon nanotubes (CNTs) have made an enormous impact on materials science, molecular biology, biomedicine, and bioanalytical chemistry. Carbon Nanotubes: Methods and Protocols provides reliable, consistent protocols on the application of CNTs in molecular biology-related fields. These are of vital importance, as the commercially available CNTs differ in purity, agglomeration state, as well as length and diameter distribution, all of which have a profound influence on the dispersability and surface properties of the tubes. The volume contains detailed sections on functionalization, toxicity, trafficking, scaffolds, and biosensors, provided by expert researchers from various fields. Written in the highly successful Methods in Molecular BiologyTM series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and notes on troubleshooting and avoiding known pitfalls. Authoritative and cutting-edge, Carbon Nanotubes: Methods and Protocols serves to contribute to the achievement of common standards and helps researchers to avoid discrepancies in future biology-related CNT studies.

"Single-walled carbon nanotubes (SWCNTs) are quasi-1D graphitic materials whose excited state properties are governed by electrostatically bound electron-hole pairs, called excitons. SWCNTs have garnered much attention recently due to their unique size-dependent optical and electronic properties. As the understanding of SWCNT photophysics continues to grow, there now exists an incredible opportunity for SWCNTs to drive novel breakthroughs in various applications including water oxidation, photovoltaics, field-effect transistors, and electron-conductive/proton permeable membranes, where nanotubes are called upon to act as light-harvesting and/or charge-transfer materials. However, underlying the eventual performance of SWCNTs in these applications is a need for a deep understanding of their photophysics. This dissertation will focus on some of the fundamental properties of SWCNTs and their photophysics, and will address some of the recent work done to understand (i) the mechanism behind population of a quantum mechanically forbidden "dark" state within the SWCNT band structure, known as the K-momentum dark exciton state, and (ii) the formation of charged excitons upon non-covalent doping of SWCNTs. Further, this work will detail two interesting applications of SWCNTs: Using SWCNTs for photoinduced charge transfer and for simultaneous proton/electron transport."--Page xv.
