Abstract:
La presente tesis doctoral se centra en el estudio exhaustivo de nanotubos de carbono funcionales por medio de técnicas de microscopía electrónica. Los nanotubos de carbono (CNTs) funcionales están atrayendo una creciente atención debido a su potencial uso para aplicaciones biomédicas, incluyendo para la adquisición de imágenes in vivo, acumulación selectiva en tumores y sistemas de administración de fármacos. Una ventaja intrínseca de los nanotubos de carbono es que su cavidad interna puede llenarse con una carga útil de interés mientras que la superficie externa puede modificarse para mejora

Abstract:
As new materials are discovered, their potential and applications are investigated widely across the various scientific disciplines for general or highly specialized applications. While new nanomaterials such as carbon nanotubes have received the greatest interest for electronics, optics, and structural composites, their applications have also been explored for biological applications such as sensing, selective cell destruction, cellular growth scaffolds, and intracellular delivery of bioactive cargos. Carbon nanotubes are unique materials particularly suited for these applications as they pos

Abstract:
Ever rising power densities and smaller transistor dimensions are increasing the challenge of thermal management within integrated-circuit chips and their surrounding packaging. In addition, the need for sustainable energy has placed urgent emphasis on energy conversion. Thermoelectric phenomena, involving the conversion of heat to electrical current, provide a central focus for both needs. Specifically, there is a need to engineer materials or composites with low thermal conductivity and high electrical conductivity for energy conversion and the opposite for heat management.

A method is described for ultrasonically spraying thin films of carbon nanotubes that have been suspended in organic solvents. Nanotubes were sonicated in N-Methyl-2-pyrrolidone or N-Cyclohexyl-2-pyrrolidone and then sprayed onto a heated substrate using an ultrasonic spray nozzle. The solvent quickly evaporated, leaving a thin film of randomly oriented nanotubes. Film thickness was controlled by the spray time and ranged between 200-500 nm, with RMS roughness of about 40 nm. Also described is a method for creating thin (300 nm) conductive freestanding nanotube/polymer composite films by infil

Since many years, carbon nanotubes (CNTs) have been considered for a wide range of applications due to their outstanding mechanical properties. CNTs are tubular structures, showing a graphene like hexagonal lattice. Our interest in the calculation of the mechanical properties is motivated by several applications which demand the knowledge of the material behavior. One application in which the knowledge of the material behavior is vital is the CNT based fiber. Due to the excellent stiffness and strength of the individual CNTs, these fibers are expected to be a promising successor for state of t

Argon diffused by a single-file mechanism in SWNTs smaller than an accessible diameter of 1.76σAr, corresponding to (7,7), (12,0) and (8,6) SWNTs but by a Fickian mechanism for SWNTs larger in diameter.

Abstract:
Dans les premières parties, le flambage du nanotube de carbone sous ses poids propres a été analysé sous hypothèse de mécanique des milieux continus. Cela montre que le rapport critique de longueur/diamètre peut aller jusqu'à 106. On utilise aussi un modèle de poutre pour étudier la valeur critique de longueur pour que les deux nanotubes se collent sous action des forces de van der Waals. Ceci dans le but d'une guide de conception de nano interrupteur. La suite de la thèse est consacrée à la fabrication des composites à base de résine avec les renforts des particules de sic mais avec les nanot

Abstract:
L'électronique moléculaire et la spintronique moléculaire sont deux domaines émergeant de la nanophysique, prometteurs pour réaliser de nouveaux types de dispositifs utiles tant pour le stockage d'information que pour l'information quantique. Ce travail de thèse a pour objet de contribuer à ces deux domaines de recherche par la réalisation de jonctions moléculaires à base de nanotubes de carbone, faisant intervenir des nanostructures magnétiques. Nous avons choisi deux approches: (i) le transport électronique à travers des nanotubes de carbone remplis de matériaux magnétiques (nanotubes hybrid

Depuis 1991, les nanotubes de carbone font l'objet de nombreux travaux de recherche, depuis leur elaboration jusqu'a l'exploitation de leurs proprietes dans des domaines aussi varies que les nanotechnologies, l'electronique moleculaire, le renforcement des composites, le stockage de l'energie leur diametre est de quelques nanometres et leur longueur peut atteindre le millimetre. Les nanotubes multiparois sont constitues de feuillets carbones arranges en couches concentriques (jusqu'a plusieurs dizaines). Les nanotubes monoparoi, d'un diametre compris entre 1 et 2 nanometres, s'associent par fa
