Book excerpt: A theoretical framework describing the carbon nanotubes interaction, involving two distinct approaches, is presented. Based on the results obtained practical applications using carbon nanotubes are further proposed. First a classical approach is employed for different geometrical configurations, such as parallel or concentric carbon nanotubes. For all the cases analytical expressions for the systems potential energies are derived. The results obtained using the classical approach are used to propose a few practical applications. These applications include a non-contact device for profiling surfaces and a custom telescopic double wall carbon nanotube for nanolithography applications. It is expected that such devices can be effectively used with major advantages. Next the interaction between nanotubes is considered using a quantum electrodynamics approach suitable for dispersing and absorbing media. Each carbon nanotube is characterized by its individual full dielectric response. The method also allows taking into account the full carbon nanotube cylindrical geometry by imposing the appropriate boundary conditions at the nanotubes surfaces. It is found that at small nanotube separations, similar to their equilibrium distances, the interaction is dominated by the collective excitations in the electron energy loss spectra originating from interband transitions. Furthermore, it is shown that the collective surface excitations and their chirality dependent characteristics play a profound role in the interaction strength in double wall carbon nanotube systems. The obtained results are in good agreement with experimental measurements on determining the chirality of individual double wall carbon nanotubes.

This book was released on 2011-02-09 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores the potential of multi-functional carbon nanotubes for biomedical applications. It combines contributions from chemistry, physics, biology, engineering, and medicine. The complete overview of the state-of-the-art addresses different synthesis and biofunctionalisation routes and shows the structural and magnetic properties of nanotubes relevant to biomedical applications. Particular emphasis is put on the interaction of carbon nanotubes with biological environments, i.e. toxicity, biocompatibility, cellular uptake, intracellular distribution, interaction with the immune system and environmental impact. The insertion of NMR-active substances allows diagnostic usage as markers and sensors, e.g. for imaging and contactless local temperature sensing. The potential of nanotubes for therapeutic applications is highlighted by studies on chemotherapeutic drug filling and release, targeting and magnetic hyperthermia studies for anti-cancer treatment at the cellular level.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the control of electronic properties of carbon nanotubes. It presents thermodynamic calculations of the formation of impurities and defects in the interaction of nanotubes with hydrogen, oxygen, nitrogen and boron, based on theoretical models of the formation of defects in carbon nanotubes. It is shown that doping and adsorption lead to changes in the electronic structure of the tubes as well as to the appearance of impurity states in the HOMO-LUMO gap. The book presents examples of specific calculations for doping of carbon nanotubes with oxygen, hydrogen, nitrogen and boron, together with numerous experimental results and a comparison with the author’s thermodynamic calculations. Possible directions of the technological processes of optimization are pointed out, as well as the perspectives of p-n-transition creation with the help of carbon nanotube arrays. The results presented were derived from the physics of the processes and a theoretical model of the technological processes. Though a wealth of empirical information on doping nanotubes has been accumulated in the scientific literature, what is lacking is a theoretical model for their analysis. As such, the book develops a thermodynamic model of the self-organization of structural elements in multicomponent systems – including carbon nanotubes, clusters and precipitates in condensed matter – and subsequently adapts it to the doping of carbon nanotubes. This approach allows readers to gain a far deeper understanding of the processes of doping carbon nanotubes.

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.

This book was released on 2023-03-28 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: FUNCTIONALIZED CARBON NANOTUBES FOR BIOMEDICAL APPLICATIONS The book highlights established research and technology on current and emerging trends and biomedical applications of functionalized carbon nanotubes by providing academic researchers and scientists in industry, as well as high-tech start-ups, with knowledge of the modern practices that will revolutionize using functionalized carbon nanotubes. Nanotechnology suggests fascinating opportunities for a variety of applications in biomedical fields, including bioimaging and targeted delivery of biomacromolecules into cells. Numerous strategies have been recommended to functionalize carbon nanotubes with raised solubility for efficient use in biomedical applications. Functionalized carbon nanotubes have unique arrangements and extravagant mechanical, thermal, magnetic, optical, electrical, surface, and chemical properties, and the combination of these features gives them widespread biomedical applications. Functionalized carbon nanotubes are relatively flexible and interact with the cell membranes and penetrate different biological tissues owing to a “snaking” effect, therefore both the pharmacological and toxicological profiles of functionalized carbon nanotubes have gathered much attention in recent times. This book covers a broad range of topics relating to carbon nanotubes, from synthesis and functionalization to applications in advanced biomedical devices and systems. As they possess unique and attractive physical, chemical, optical, and even magnetic properties for various applications, considerable effort has been made to employ functionalized carbon nanotubes as new materials for the development of novel biomedical tools, such as diagnostic sensors, imaging agents, and drug/gene delivery systems for both diagnostics and clinical treatment. Audience The book is intended for a very broad audience of researchers and scientists working in the fields of nanomaterials, nanomedicine, bioinspired nanomaterials, nanotechnology, and biomedical application of nanomaterials.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Using dispersion corrected density functional theory (DFT) methods, we study the interaction between oligo(phyenylene ethynylene)s (OPEs) having different end groups: aldehyde (ALD) and dithiafulvene (DTF) (abbreviated as OPE-ALD and OPE-DTF respectively) with single-wall carbon nanotube (SWCNT). We investigate the structure and electronic properties of isolated OPEs and OPE/SWCNT molecular combinations. This research is important for developing of more effective linear conjugated oligomer-based dispersants for SWCNTs. In particular, we focus on understanding of the role of the end groups in the dispersion of nanotubes. We consider a number of dispersion corrected DFT methods: B97D, wB97XD, and CAM-B3LYP and employ the 6-31G* basis set in all of our calculations. We obtain geometries, dipole moments, binding energies, and intermolecular distances for the oligomer and nanotube combinations. The comparison of results obtained using different DFT approximations is also made. Our results show that OPE-DTF interact more strongly with the nanotube than OPE-ALD.
