Enhanced Sputtering Yields from Single-Ion Impacts on Gold Nanorods

, 2013
Sputtering yields, enhanced by more than an order of magnitude, have been observed for 80 keV Xe ion irradiation of monocrystalline Au nanorods. Yields are in the range 100–1900  atoms/ion compared with values for a flat surface of ≈50.

Nanoparticle Shape Dictates Catalytic Performance in Selective Hydrogenation of Butadiene Over Au‐Pd Core‐Shell Nanoparticles

Advanced Functional Materials, EarlyView.
Controlling the exposed crystal facet of shape‐controlled Au‐Pd core‐shell catalysts though colloidal synthesis enhances their catalytic performance in the industrially relevant selective hydrogenation of butadiene. ABSTRACT Selective hydrogenation of butadiene is a critical step in purification of alkene feedstocks for polymer production and is ...

Sulfide-Arrested Growth of Gold Nanorods [PDF]

Chemistry of Materials, 2005
The growth of gold nanorods can be arrested at intermediate stages by treatment with Na(2)S, providing greater control over their optical resonances. Nanorods prepared by the seeded reduction of AuCl(4) in aqueous cetyltrimethylammonium bromide solutions in the presence of AgNO(3) typically exhibit a gradual blueshift in longitudinal plasmon resonance,

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
