1. Desenvolvimento e estudo físico-químico de compósitos de nanotubos de carbono / Physical chemical study and development of carbon nanotubes composites
This thesis presents for the first time nitrogen-cup-stacked carbon nanotubes with hydrophilic and semiconducting properties synthesized by alcohol precursor. The hybrid carbon fiber/carbon nanotubes composite have three-dimensional geometry and nanostructure. The material was prepared via fixed-bed chemical vapor deposition reactor. In this process nitrogen

2. Sintese e caracterização de nanotubos e fulerenos nitrogenados gerados por arco aletrico
This thesis work aims to synthesize and to characterize structural and chemically nanotubes and fullerenes containing nitrogen. Both nanotubes and fullerenes syntheses were performed using an arc-discharge system filled with gaseous mixtures of He e N2. Electron microscopy samples analysis shows that N2 concentration inside the arc-discharge chamber influenc
