A new method uses gold to assemble multi-element nanoparticles under mild conditions, offering improvements in catalytic ...

Gold nanoparticles' size and shape are critical for a range of applications—from drug delivery to catalysis, sensing and electronics—due to their physical, chemical and optical properties.

Peroxyd of manganese does this, and the gold dissolved in such a solution is a sub-chloride. The most useful and important vehicle for dissolving gold is aqua regia, (royal water), composed of two ...

In the presence of graphene, sheet resistance was reduced by at least 50%. “This is a comparable improvement as that obtained through gold chloride doping”, said the researchers in the paper. “However ...
