Influence of the precipitation agent in the deposition-precipitation on the formation and properties of Au nanoparticles supported on [Al.sub.2][O.sub.3]
Article Abstract:
Different characterization techniques are used investigate the [Al.sub.2][O.sub.3]-supported Au catalysts in order to elucidate the geometric structure and the electronic states of the gold particles dependent on the used precipitation agent NaOH or urea. The influence of the precipitation agent on the deposition of gold nanoparticles on oxidic nanoparticles is discussed.

Spatial structure of Au8: Importance of basis set completeness and geometry relaxation
Article Abstract:
A study calculated the relative stabilities of the lowest energy structures for the gold octamer, Au8, employing highly correlated ab intio methods. The importance of geometry relaxation beyond the MP2 level of theory as well as the need for basis sets toward the complete limit (CBS) is discussed.
