A phenomenon of surface energy plays a central role in analyses of most aspects of phase transitions in general and crystallization specifically. If for liquid surface energy (tension) can be measured directly for crystals such measurements practically impossible to carry out with any level of re...

Numerical simulation of nucleation phenomena during crystallization demands a definition several parameters of the clusters of crystalline molecules in initial amorphous phase. Among of such key parameters are a numbers of molecules on the surface of cluster these can be transformed from one phas...

A phenomena of spontaneous appearance of crystal phase inside of liquid and then self sustained growth up to the point of complete transformation of liquid into crystal is the very commonly observed for producing ice in refrigerator and most paradoxical from point of clear demonstration of ...

One of the models of layer by layer growth of crystal is based on the random process of forming two dimensional nucleus that schematically displayed on the following picture:

Fig. 1. Schematic view of two dimensional nucleus on the flat crystal surface. 

A change...

An observation of the crystals growing with flat surfaces and in the same time difficulty of quantitative application of the two dimensional nuclei model for quantitative explanation of experimental data for temperature dependence of rate of crystal growth as well an occasional the observation spira...

A model of thermally activated crystal growth is a foundation for theory of crystallization.

In the model of thermally activated crystal growth addresses to the elemental act of incorporation of molecule on the surface into crystal. In the spite (or because) simple mathematical formulation ...

The model of thermally activated crystal growth as described in the article leaves aside the very important feature of crystal growth phenomena namely the influence of surface energy.

A difference in levels of free energy between molecule situated at the surface of the crystal incorpora...

A process of phase transition of first-order such as crystallization is accompanied with heat release that reflected a difference between energy levels of crystal phase and surrounding it matter that is the 'soil' for the growing crystal. The amount of heat is equivalent to difference of enthalpies ...

Crystals are state of the matter with long-range order of atoms in it. It means that in some direction the pattern of atoms locations will periodically repeat themselves. Conventionally this statement will be true in any direction in three dimensional space but for some special cases such as liqu...
