Multiply-twinned intermetallic AuCu pentagonal nanorods.

Monodispersed intermetallic AuCu pentagonal nanorods with controlled size and composition have been developed by a seed-mediated growth route. The AuCu/C nanomaterial catalyzed the coupling reaction of sulfonamide with benzyl alcohol in good to excellent yields.

HIGH RESOLUTION STUDIES OF SMALL PARTICLES OF GOLD AND SILVER I. Multiply-twinned particles

The structure of multiply-twinned particles of gold and silver found in the early stages ofparticulate growth has been studied using direct lattice imaging methods with the Cambridge University 600 kV high resolution electron microscope. There was widespread evidence for the presence of strain-relieving partial dislocations in icosahedral particles. However, the possibility of imaging artefacts...

Thermodynamic Analysis of Multiply Twinned Particles: Surface Stress Effects

In nanoparticle technologies, such as SERS, fuel cell catalysis and data storage, icosahedral and decahedral nanoparticles, owing to their defect structure, provide higher functionality than their single-crystal Wulff counterparts. However, precise control on the yield of multiply twinned structures during solution synthesis has been challenging. In particular, it is difficult to synthesize ico...

Dependence of the localized surface plasmon resonance of noble metal quasispherical nanoparticles on their crystallinity-related morphologies.

The absorption spectra of 5 nm noble metal nanoparticles (Ag, Au, and Cu) with typical morphologies of multiply twinned particles (MTPs) and single crystals are calculated by using the discrete dipole approximation method. Among the considered morphologies, it is found that icosahedral, cuboctahedral and truncated octahedral particles behave like quasispherical particles whereas the optical res...

Surface structure and energetics of multiply twinned particles

Experimental results from thermally annealed particles of silver and gold in the size range 10-50 nm show the presence of re-entrant surfaces on the decahedral multiply twinned particles (MTPs). A theoretical model is developed to explain these results based on the Wulff construction modified to include twin-boundaries. In addition to reproducing the re-entrant surfaces, the theory suggests tha...
