Nanoparticles are a state of matter that has properties different from either molecules or bulk
solids. In the present work, we review the shape and structure of nanometer-sized particles; …

A comprehensive review is given on experimental studies of small particles with fivefold
symmetry accompanied by an in‐depth theoretical description of their characteristics and …

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 …

The energetics of nickel clusters over a broad size range are explored within the context of
the many‐body potentials obtained via the embedded atom method. Unconstrained local …

We report electron-microscopy and high-resolution x-ray-scattering measurements of rapidly
quenched Al 6 Mn. The electron-diffraction pattern shows icosahedral symmetry. Peaks in …

The energetics of multiply twinned particles (MTPs) are investigated using elasticity theory.
This allows the homogeneous strain models to be critically compared with the disclination …

A mechanistic understanding of the growth of multiply twinned nanoparticles (MTPs), such
as decahedra (Dh) and icosahedra (Ih), is crucial for precisely controlled syntheses and …

Multiple twinning in crystalline solids forming quintuples of twins is known since 1957
(Segall). It ever has attracted the attention not only of crystal growth and crystallography …

The applications of supported metal catalysts vary widely, from selective hydrogenation in
the fine chemicals industry to the control of vehicle emissions. Yet many basic questions …

This note makes two points: First, the discovery of “icosahedral symmetry” in metal alloy films
while interesting is hardly unexpected for those familiar with the literature. There is an …
