Reduction-resistant [Au25(cyclohexanethiolate)18]0 with an Icosahedral Au13 Core

Tangential ligand-induced strain in icosahedral Au13.

Metal nanoclusters1 (and gold nanoclusters in particular2) can exhibit structures that differ significantly from that corresponding to the bulk, ones that depend strongly on cluster size. Detailed knowledge of these structures is crucial for understanding and predicting nanocluster properties, including chemical, electrical, magnetic, and optical ones. The experimental determination of atomisti...

Metal core bonding motifs of monodisperse icosahedral Au13 and larger Au monolayer-protected clusters as revealed by X-ray absorption spectroscopy and transmission electron microscopy.

The atomic metal core structures of the subnanometer clusters Au13[PPh3]4[S(CH2)11CH3]2Cl2 (1) and Au13[PPh3]4[S(CH2)11CH3]4 (2) were characterized using advanced methods of electron microscopy and X-ray absorption spectroscopy. The number of gold atoms in the cores of these two clusters was determined quantitatively using high-angle annular dark field scanning transmission electron microscopy....

Drosophila A virus is an unusual RNA virus with a T=3 icosahedral core and permuted RNA-dependent RNA polymerase.

The vinegar fly, Drosophila melanogaster, is a popular model for the study of invertebrate antiviral immune responses. Several picorna-like viruses are commonly found in both wild and laboratory populations of D. melanogaster. The best-studied and most pathogenic of these is the dicistrovirus Drosophila C virus. Among the uncharacterized small RNA viruses of D. melanogaster, Drosophila A virus ...
