FCC disordered binary alloyscharge shieldingpolyvalent soluteempty core Fermi Thomas pseudopotentialCu alloysIn the f.c.c., disordered, binary alloys of the noble metals, the deviations from Vegard's Law which occur, are studied with emphasis on the shielding of the charge of a polyvalent solute ...
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 ...
For the convenience of imposing shear stress on neighbouring dynamic atoms, top and bottom slabs of ~12 Å thick (more than twice the cutoff radius) are frozen by setting the interatomic force to zero. An exemplary run of the SCM process and the crystallographic relation are illustrated in...
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 crystalline phases constituting the material were investigated by synchrotron X-ray diffraction experiments in transmission mode (beam energy 100 keV; beam size 0.2x0.2 mm2). The beam was oriented parallel to the samples axial direction, at a radius of r = 3 mm. Needle-shaped specimens ...
