The surfaces of nanoscale gold particles and components are oxide-free under normal ambient conditions. This unusual attribute permits the exploration of microstructures and functionalities that would not be feasible ...

Cap-shaped metal nanoparticles have optical spectra with significant absorption in the infrared. Such shapes, produced by physical vapor deposition onto a polymer particle template, can be readily separated from one another ...

Mesoporous gold sponge may be prepared by the removal of aluminium from AuAl₂ by an alkaline leach. The resulting material has nanoscale pores and channels, with a high specific surface area that can be exploited ...

Metal-insulator-metal (MIM) capacitors play an important part in many integrated electronic circuits in the areas of analog, microwave, and radio frequency systems. However the transverse dimensions of current MIM capacitors ...

We show that oxidation of protective thiol ligands and the exothermic reduction of surface area are important factors in the sintering of thiol-stabilized gold nanoparticle films. We also present a chemical treatment to ...

The unique optical properties of gold nanorods, which exhibit tuneable absorption as a function of their aspect ratio, suggest that they might have potential applications in coatings for solar control on windows. Here ...
