Axial dispersion coefficients of the liquid phase in bubble columns

Great attention has been paid to nanoclusters having face-centered-cubic (fcc) metal kernels, because of the similarity of metal packing to that of bulk gold. So far, there is no precedent example of an all-alkynyl-protected fcc gold nanocluster with more than 100 gold atoms. We report the synthesis and total structure determination of an alkynyl-protected gold nanocluster [NEt3H]2[Au110(p-CF3C6H4CC)48] (Au 110 ). It has an fcc Au86 kernel with 24 peripheral Au­(CCR)2 staples. The Au86 kernel consists of six close packing layers in the pattern of Au6:Au16:Au21:Au21:Au16:Au6. Electronic absorption spectroscopy shows Au 110 has a molecular-like discrete electronic structure, and transient absorption experiments reveal its nonmetallic nature.
