Stable nanoclusters (approximately 2 nm in diameter) of copper, silver, gold, palladium, and ruthenium coated with hydrophobic coronas are easily trapped in self-assembled "soft crystal" hexagonal phase gels made of water and surfactants. The system's crystal structure and phase behavior are studied in detail. A partial phase diagram showing the hexagonal(More)
Experimental Section Cross-polarised optical microscopy was performed using an Olympus BH-2 microscope coupled to a Leica DM-IRB digital camera. The gel samples were sealed two glass plates using vacuum grease to enable aging observations. Small angle X-ray scattering (SAXS) experiments were performed using a rotating anode with a copper target (λ = 1.54(More)
