Gold Nanoparticles Self-Assemble Into Small Clusters

This was determined using Small-Angle X-ray Scattering (SAXS) at BESSY II. A thorough examination with an electron microscope (TEM) confirmed their result. "The research on this phenomenon is now proceeding because we are convinced that such nanoclusters lend themselves as catalysts, whether in fuel cells, in photocatalytic water splitting, or for other important reactions in chemical engineering", explains Dr. Armin Hoell of HZB. The results have just appeared in two peer reviewed international academic journals.
