Phason strain in an energetic growth model of a quasicrystal.
The mathematical descriptions of quasicrystal' show that for a given quasicrystalline symmetry, there is an uncountably infinite number of distinct packing of unit cells. At present, these packings [different local isomorphism (LI}classes] and the unit-cell decoration cannot be determined simultaneously from diffraction data. Steinhardt and co-workers introduce three criteria for the identifica...
متن کاملNanodomains due to phason defects at a quasicrystal surface.
Among the three coexisting types of terraces found on the twofold surface of the d-Al-Cu-Co quasicrystal, nanodomains are essentially observed on the transition-metal rich ones, with a coherent interface boundary. Both clean surface and Ag growth analyses, demonstrate that nanodomain surfaces are structurally identical to one of the two other terraces, which contains 85 at. % Al. We provide evi...
متن کاملHeat Transfer in Three-Dimensional Flow along a Porous Plate
An analysis of heat transfer in the flow of a viscous, in-compressible fluid along an infinite porous plate is presented when the plate is subjected to a transverse sinusoidal suction. The flow field becomes three-dimensional due to this type of suction velocity. Expressions for the flow and temperature fields are obtained by series expansion method. It is found during the course of discussion ...
متن کاملMHD Three-Dimensional Stagnation-Point Flow and Heat Transfer of a Nanofluid over a Stretching Sheet
In this study, the three-dimensional magnetohydrodynamic (MHD) boundary layer of stagnation-point flow in a nanofluid was investigated. The Navier–Stokes equations were reduced to a set of nonlinear ordinary differential equations using a similarity transform. The similarity equations were solved for three types of nanoparticles: copper, alumina and titania with water as the base fluid, to inve...
متن کاملPhason elasticity and atomic dynamics of quasicrystals
As the order of a quasicrystal is quasiperiodic, it can be described as an irrational cut through a periodic structure in a higher-dimensional space. This mathematical trick has important consequences for the low energy excitations that can occur. Translating the cut space to a different position is a symmetry operation, which changes the quasicrystal structure, but not its energy. A small brea...
