TLDR
The theory of phase separation from a single phase fluid by a spinodal mechanism is given in this paper, where the predicted structure may be described in terms of a superpositioning of sinusoidal composition modulations of a fixed wavelength, but random in amplitude, orientation, and phase.
Abstract
The theory of phase separation from a single phase fluid by a spinodal mechanism is given. The predicted structure may be described in terms of a superpositioning of sinusoidal composition modulations of a fixed wavelength, but random in amplitude, orientation, and phase. Sections through a calculated structure are shown. These show that the structure has many of the geometrical features found in phase separable glasses, in particular the high degree of connectivity among particles of each phase.

Dynamics and stability of thin liquid films

TL;DR: The dynamics and stability of thin liquid films have fascinated scientists over many decades: the observations of regular wave patterns in film flows along a windowpane or along guttering, the patterning of dewetting droplets, and the fingering of viscous flows down a slope are all examples that are familiar in daily life.

Free Energy of a Nonuniform System. I. Interfacial Free Energy

TL;DR: In this article, it was shown that the thickness of the interface increases with increasing temperature and becomes infinite at the critical temperature Tc, and that at a temperature T just below Tc the interfacial free energy σ is proportional to (T c −T) 3 2.

On spinodal decomposition

TL;DR: In this article, the stability of a solid solution to all infinitesimal composition fluctuations is considered, taking surface tension and elastic energy into account, and it is found that for infinite isotropic solids, free from imperfections, the spinodal marks the limit of metastability to such fluctuations only if there is no change in molar volume with composition.

Phase diagrams for ceramists

TL;DR: One of the popular books now is the phase diagrams for ceramists as discussed by the authors. You may be confused because you can't find the book in the book store around your city. And when you have found the store to buy the book, it will be so hurt when you run out of it.

Free Energy of a Nonuniform System. III. Nucleation in a Two‐Component Incompressible Fluid

TL;DR: In this article, the saddle point in the expression derived in Paper I (see reference 8) for the free energy of a nonuniform system was used to derive the properties of a critical nucleus in a two-component metastable fluid.

On spinodal decomposition in cubic crystals

TL;DR: In this paper, the anisotropy of all factors influencing the mechanism of spinodal decomposition was considered for crystals of cubic symmetry, and it was shown that elastic aeolotropy should give rise to {100} plane waves if 2 C 44 − C 11 + C 12 > 0 or {111} plane wave if 2C 44 − c 11 + c 12
