Abstract

The study of nanometric systems has gained great importance in the scientific community and one particular issue of interest is nano-aggregates: nanoparticles with 2 - 10^7 atoms with varied compositions and forms. They can present quantum effect in the small ones, macrocospic in the bigger ones or same an intermediate situation between these limits. Due to this flexibility, controlling the size, the composition and the format of a nano-aggregate, it is possible to generate new materials and model systems for studies in catalysis and optoeletronics, for example. This area is not extensively explored in Brazil, however, of great importance in the international community. The proposal of this work is the development and construction of the instrumentation for nano-aggregate experimental studies for metals systems with size ranging from 2 to 50 atoms. In particular, in this project we focus on the development and characterization of a size selected metal aggregate source. (AU)
