Two-body forces have been assumed to act between the atoms in an f.c.c. cluster containing an interstitial solute atom. The solvent metal atom mutual interaction is given by a modified Morse potential and the solvent-solute interaction is of the soft sphere type. Various diffusion paths were...
An atomic transition model of a face-centered cubic (fcc) crystal to a primitive hexagonal ω and body-centered cubic (bcc) structures has been crystallographically built. The fcc structure can transform into the ω structure through a local shuffling or displacement of atoms about 0.4014 Å in...
5 principles Atoms are basic building block Atoms of same element are identical Atoms of different elements are different Atoms of different elements can combine in definite proportions to form compounds Atoms are indivisible by chemical processes First use of symbols Atom can be subdivided. Discovered...
Solid−Fluid and Solid−Solid Equilibrium in Hard Sphere United Atom Models of n-Alkanes: Rotator Phase Stability†.Solid−Fluid and Solid−Solid Equilibrium in Hard Sphere United Atom Models of n-Alkanes: Rotator Phase Stability†.We present a study of the phase behavior for models of...
If you take the example of diamond, silicon and germanium, they all have the diamond crystal structure, but their band diagram is quite different. Spherical atoms wouldn't explain this. My suggestion is: don't try to stretch this simplistic model beyond its capability. Even if you take atom...
A schematic model is proposed for understanding the boson peak as a consequence of the coupling between slowly decaying density fluctuations and the transverse sound modes that develop in the amorphous solid. The present analysis demonstrates that the nature of the dynamics of defect densities in the...
Based on a hard sphere model it is not too difficult to show that considerably less room is available for carbon to squeeze into in the α-Fe interstitial site relative to the γ-Fe site. More severe lattice bond straining in the former means that less carbon will dissolve interstitially ...

Electronic polarisation: in atoms, positive ions are surrounded by electron clouds. Since the electrons are very light, they respond rapidly to the action of an applied electric field.Figure 7.6shows a schematic of an atom being polarised due to the action of the fieldE0. ...
model: generic name of the solid (e.g., "chair"). description: short description (1 line) of the solid. contactMaterial: name of the contact material. When the boundingObjects of Solid nodes intersect, the contactMaterial is used to define which ContactProperties must be applied at ...
