Atomic-scale determination of surface facets in gold nanorods [PDF]

, 2012
It is widely accepted that the physical properties of nanostructures depend on the type of surface facets1, 2. For Au nanorods, the surface facets have a major influence on crucial effects such as reactivity and ligand adsorption and there has been ...

Mechanical properties of ceria nanorods and nanochains; The effect of dislocations, grain-boundaries and oriented attachment [PDF]

, 2011
We predict that the presence of extended defects can reduce the mechanical strength of a ceria nanorod by 70%. Conversely, the pristine material can deform near its theoretical strength limit.

Enhanced Sputtering Yields from Single-Ion Impacts on Gold Nanorods [PDF]

, 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.

Fast and Facile Synthesis of LiMn2O4 Nanorods for Li Ion Battery by Microwave Assisted Hydrothermal and Solid State Reaction Methods

International Journal of Electrochemical Science, 2014
A rapid and efficient two-steps growth strategy has been adopted to synthesize monodisperse singlecrystalline spinel LiMn2O4 nanorods. The first step is to synthesize crystalline β-MnO2 nanorods through rapid microwave hydrothermal process followed by ...

Sputtering yields exceeding 1000 by 80keV Xe irradiation of Au nanorods [PDF]

, 2014
Using experiments and computer simulations, we find that 80 keV Xe ion irradiation of Au nanorods can produce sputtering yields exceeding 1000, which to our knowledge are the highest yields reported for sputtering by single ions in the nuclear collision ...
