N-Heterocyclic carbenes (NHCs) have become one of the most widely studied class of
ligands in molecular chemistry and have found applications in fields as varied as catalysis …

Atomically precise pieces of matter of nanometer dimensions composed of noble metals are
new categories of materials with many unusual properties. Over 100 molecules of this kind …

X-ray scattering is a structural characterization tool that has impacted diverse fields of study.
It is unique in its ability to examine materials in real time and under realistic sample …

Atomically precise gold clusters are highly desirable due to their well‐defined structure
which allows the study of structure–property relationships. In addition, they have potential in …

Phosphine-stabilized gold nanoparticles, originally formulated as Au55 (PPh3) 12Cl6 by
Schmid et al. 1 in 1981, have been widely investigated as models for metallic catalysts2 and …

In early 1995, several of us1 were exploring the properties of the first size-purified forms of
the giant aurothiol cluster compounds, denoted by c-Au: SR (Figure 1a). 2 We found that …

This contribution is a preprint of one chapter of Professor Wang's edited new book
“Characterization of Nanophase Materials”(ISBN 3–527–29837–1), published by WILEY …

A systematic exploration of the growth of Au clusters has revealed a critical size for the
formation of stable assemblies. Mass-spectrometric measurements of clusters, as grown in …

Ligand exchange reaction is a very important and useful tool for preparing functionalised
metal nanoparticles. Understanding the mechanism of this process is essential for rational …

Small metal clusters, like Au 55 (PPh 3) 12 Cl 6, which fall in the size regime of 1–2 nm are
colloidal nanoparticles with quantum properties in the transitional range between metals …
