An approach of identifying atoms in different shells of an atomic cluster is presented, using which we have distinguished the surface atoms of the Lennard-Jones clusters containing 7–617 atoms, or termed as LJ7 to LJ617 clusters. The core structure change of the clusters has been observed, ...
Balian and Bloch have shown4 that such shells are the likely result of particularly stable electronic structures: electrons in a spherical cavity (approximating the potential in the clusters) follow semiclassical triangular or square orbits, leading to a shell structure similar to that in atoms5, ...
In engineering applications, various kinds of shell structures are widely used, such as sheet metal in an automobile, the fuselage, wings and rudder of aircraft, walls of pressure vessels, architectural domes, electronic device shells, etc. The characteristic of a shell structure is that the dimen...

Although the structure of these shells is used to explain nanoscopic properties, experimental structural insight is still missing. Here we show how to access the hydration shell structures around colloidal nanoparticles in scattering experiments. For this, we synthesize variably functionalized magnetic iron...

Bohr’s Atomic model suggests that electrons move in specific circular paths, or orbits, around the nucleus. These orbits are also known as shells, and each shell has a fixed energy level. The energy level of a shell is constant and each shell can contain a limited number of electrons. Th...
In nearly all first-principles calculational approaches to the many-particle problem of a cluster, replacing one or more atoms (X) in a homoatomic cluster (Xn) by one or more atoms of a different element (Y) drastically increases the number of possible structural isomers that have to be ...
