Motivated by the structure evolution experiments of Janus NiAu nanoparticles (NPs), we present a detailed study on the thermodynamic evolution of Ni and Au NPs with different ratios of Au and Ni through the molecular dynamics (MD) simulations. It is found that, for fixed Ni particle size (5.8...

Thus, the radius of the Ewald sphere is much larger and the diffraction pattern reveals much more of the 2-D distribution of the reciprocal lattice. By adjusting the electron lenses a diffraction pattern can be varied. It consists of a pattern of dots for a single crystal, or a ring ...
The gyration radius of Au nanoparticle, Rg, is defined as where n is the number of atoms in the cluster, ri is the coordinates of the ith atom in the cluster and rc is the center of mass of the cluster. The diameter of nanoparticle D is defined as . In each kinetic Monte Carlo ...

The alloys containing the smaller radius rare-earth atoms (≤ 1.8013 Å, i.e., Al88(Gd1—xErx)8Ni4 for all x) produce fcc Al nanocrystals on devitrification. However, they do not show a glass transition temperature (T g), although they appear to be amorphous by XRD and show a ...
(AFM) is one of the most powerful techniques to investigate the status of surface conditions of either thin film or single crystals, which are being to employ for solar cell applications. In general, the tips are made by Si3N4containing typical 4 side pyramidal, radius of 20–50 mm, apex...
Calculate the radius of iridium at, given that Ir has an FCC crystal structure, a density of 22.4 g/cm{eq}^3 {/eq}, and an atomic weight of 192.2 g/mol. Density: The term density can be evaluated as the fraction of m...

The cascade radius R can be, within the regime of spherical cascades, estimated from classical theory of nuclear stopping power28,29. In practice, we used the SRIM code that implements an integral calculation to obtain mean range tables, based on cross sections from the widely used Ziegler−...
