Silver crystallises in a face centred cubic unit cell. Each side of the unit cell has a length of 500 pm. Calculate radius of the silver atoms (Assume that the atoms just touch each other on the diagonal across the face of the unit cell i.e. each face atom is touching four atoms) ...

It is well known that materials with a face-centered cubic crystal lattice, the primitive unit cell of which contains only a single atom, have only acoustic phonons and no optical phonons29,30. It should be noted that the presence of nanodiamonds in the film would manifest a couple of ...

THREE forms of molybdenum monocarbide (MoC) having a hexagonal unit cell have been reported in the literature 1 . In a recent note, Clougherty, Lottrop and Kafalas 2 have described a high-pressure synthesis of a new face-centred cubic molybdenum carbide, which they designate α-MoC. This ...

Direct numerical simulations (DNS) are performed in a triply periodic unit cell of a face-centred cubic (FCC) lattice covering the unsteady inertial, to fully turbulent, flow regimes. The DNS data are used to quantify the flow topology, integral scales, turbulent kinetic energy (TKE) transport...
