The segregation energy of diluted species in a matrix can be calculated by first principles. These calculations are generally very computational demanding. The existing empirical models which use the difference in surface tensions to predict the segregation energy are limited, because they do...

The concept of a global phase diagram – a diagram in the space of fluid interaction parameters in which regions of similar types of phase behavior are demarcated – has proved very valuable in both theoretical and experimental studies of fluid mixtures. This type of work sheds light on the...
