RECENTLY, with the increase of the resolving power of the electron microscope, it has become possible to make a direct observation of a crystal lattice composed of large molecules. J. W.

The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit cell with ion locations indicated (a) and a space filling model (b ...

it determines the size and shape of the lattice “box” and which atoms will go into it. Then, it predicts the arrangement of atoms within the box. For each diffraction pattern, the model ...

Traditional methods, however, depend on the "lattice constant," a property unique to each crystal. This approach ... from experimental data. Their model is based on molecular dynamics, which ...

Their findings, published in the journal “Science Advances,” described a lattice arrangement of three different layers of ferroelectric crystals (in this case, of barium titanate, strontium ...

Hot material The crystal structure of cordierite gives the material its unique thermal ... In their study, Dove and Li used advanced molecular dynamics simulations to accurately model the behaviour of ...
