Probing the electronic delocalization in a cyclic pyrazine ruthenium cluster hexamer
(ELSEVIER SCIENCE BV, 2010)
[Ru(3)O(CH(3)COO)(6)(pz)(CO)](6) is a cyclic hexamer species encompassing six triangular ruthenium cluster centers bridged by pyrazine ligands. The electronic communication among the cluster units strongly depends on their ...
ALMA Evidence for Ram Pressure Compression and Stripping of Molecular Gas in the Virgo Cluster Galaxy NGC 4402
(IOP Publishing, 2020)
High-resolution (1 '' x 2 '') Atacama Large Millimeter Array CO(2-1) observations of the ram pressure stripped galaxy NGC 4402 in the Virgo cluster show some of the clearest evidence yet for the impacts of ram pressure on ...
SPIN-ORBIT EFFECTS ON HEAVY-METAL OCTAHEDRAL CLUSTERS
(ELSEVIER SCIENCE BV, 1993)
The relativistic electronic structure of octahedral Mo6, W6, Ag6 and Au6 clusters has been investigated using the self-consistent field Dirac scattered wave (SCF-DSW) method. It is shown that spin-orbit interaction breaks ...

Modified genetic algorithms to model atomic cluster structures: CuSi clusters
(ELSEVIER, 2004-07-26)
This paper presents the results obtained using a genetic algorithm (GA) to search for stable structures of Cu-silicon clusters. In this work the GA uses a semiempirical energy function to find the best cluster structures, ...
Modified genetic algorithms to model cluster structures in medium-size silicon clusters
(American Physical Society, 2004)
Genetic algorithms (GA) were used to investigate the stable isomers of silicon clusters. In order to find the cluster structures, a semiempirical energy function was used by the GA that were further optimized using ...
Molecular characterization of SSS139, a new satellite DNA family in sibling species of the Drosophila buzzatii cluster
(Sociedade Brasileira de Genética, 2008)
We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group). The sequences were AT-rich (69%) with ...
Estudo teórico: da adsorção de etanol em clusters de Cun e Aun (n = 10-20)
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-08-24)
In this work, we study aggregates, which we will call clusters of copper and gold with and without the adsorbed ethanol molecule. First, we investigated the most favorable positions for ethanol adsorption to occur in ...
