Carbon nanostructures are regarded as front runner candidates to substitute silicon in the further miniaturization and performance improvement of electronic devices toward the nanoscale [1]. Despite being an intense\u00a0 research field due to studies on carbon nanotubes, the investigation of carbon nanostructures experienced a\u00a0 boom after the first isolation and measurement of a graphene sheet, in 2004 [2]. While theoretical methods\u00a0 predict several new and interesting behaviors for such systems, lack of control on synthesis and large scale\u00a0 reproducibility are the main challenges for experimentalists to transform the science of carbon into real-world\u00a0 technology. However, bottom-up pre-programmed routes for the production of narrow and pristine systems\u00a0 have been shown to be possible [3] and the establishment of a theory-based library of carbon nanostructures\u00a0 properties is fundamental to help experimentalists in the search for systems aiming targeted applications. Here\u00a0 we will show examples our group produced for such library, with emphasis on the theoretical study of two classes of\u00a0 carbon nanoribbons build up from molecular building blocks. Our computational studies are focused\u00a0 on electronic structure and transport [4], with models including spin-polarized tight-binding and density functional theory for electronic structure, and a combination of Landauer formalism and Green\u2019s function, as well\u00a0 as efficient algorithms [5], for transport. We highlight how different assemblies result in dramatic changes in\u00a0 the physical properties of these carbon nanostructures, allowing the use of their atomic structure and magnetic\u00a0 properties to fine tune the electronic and transport properties of these systems.\u00a0

Diversas aplica\u00e7\u00f5es podem requerer o uso de algum tipo de extra\u00e7\u00e3o como etapa de preparo de amostra. Alguns exemplos s\u00e3o o preparo de amostras de fluidos biol\u00f3gicos, assim como aplica\u00e7\u00f5es em amostras ambientais tais como efluentes industriais, \u00e1guas residu\u00e1rias, \u00e1guas superficiais, e \u00e1guas de consumo e abastecimento, entre outras. Dadas as suas caracter\u00edsticas, as diversas formas de extra\u00e7\u00e3o em fase s\u00f3lida miniaturizadas (\u00b5SPE) s\u00e3o bastante compat\u00edveis com a cromatografia l\u00edquida de alta efici\u00eancia em escala capilar (cLC), possibilitando o acoplamento sequencial entre ambas. Nesse contexto, a utiliza\u00e7\u00e3o da \u00b5SPE tem como objetivos principais a extra\u00e7\u00e3o dos compostos de interesse presentes na matriz, por meio de ampla possibilidade de escolha de materiais seletivos; al\u00e9m de oferecer a pr\u00e9-concentra\u00e7\u00e3o dos analitos aos n\u00edveis detect\u00e1veis de interesse.

Resumo:
Generation of volatile compounds offers a potential of superior sensitivity even when using relatively simple and cheap instrumentation. The main reason for the popularity of volatile compound generation lies in the principle of the method. It involves separation from the sample matrix offering considerable suppression of matrix effects. Further, high efficiency of transport of gaseous analyte to the detector and simple analyte preconcentration provide exceptional detection power. By far the most popular volatile compounds are hydrides of As, Sb, Bi, Ge, Pb, Se, Te and Sn. Besides hydrides and “cold” Hg vapor, there are also other analytically useful volatile compounds namely alkyl derivatives and volatile forms of Cd. Generation of volatile species of transition and noble metal has also been introduced.
An assessment of current experimental approaches to generation of volatile compounds as well as an outlook on future developments will be presented. Also analyte preconcentration in quartz atomizers (QTA) with subsequent detection by atomic absorption spectrometry will be treated. Finally, the current knowledge of processes involved in hydride atomization and in the whole analytical procedure employing hydride trapping in various modifications of QTA will be outlined. Emerging approaches to the improvement of QTA for on-line atomization as well as for analyte preconcentration will be discussed and possible solutions will be proposed.\u00a0<\/p>\n
