Phase Transitions: Melting and Freezing

Phase Transitions: Melting and Freezing

Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the concentration...

Solid–Solid Solutions

Solid–Solid Solutions

The temperature-composition phase diagram of two solids, A and B, which are immiscible in the solid phase but form miscible liquids, shows that when the temperature is low, these two exist as separate, pure solids (A and B). As the temperature increases, they transition into a single-phase liquid solution where A and B coexist. Moving from point a1 to a2 in the phase diagram, the composition changes such that solid B begins to separate from the solution, enriching the remaining liquid with A.

Phase Transitions

Phase Transitions

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to occupy...

Phase Transitions

Phase Transitions

A phase transition is the process in which a substance changes from one state of matter to another, like from a solid to a liquid, liquid to gas, or vice versa, at a specific temperature and under given pressure conditions. This change is spontaneous and is affected by alterations in temperature and pressure. These parameters impact the strength of the forces between molecules (intermolecular forces) in the substance.During a phase transition, both the initial and final phases of the substance...

Two Components: Liquid–Liquid Systems

Two Components: Liquid–Liquid Systems

A pressure-composition phase diagram explicitly describes the behavior of an ideal solution of two volatile liquids under varying pressures and compositions. A pressure-composition diagram has two main curves. The bubble point curve represents the plot of pressure versus liquid mole fraction. It indicates the pressure at which the first bubble of vapor forms from the liquid phase as the system pressure decreases.The dew point curve is the pressure versus vapor mole fraction. It indicates the...

Background:

Liquid crystals exhibit diverse phases with complex interfacial behaviors.
Understanding these interfaces is crucial for predicting material properties and designing new materials.
Previous studies have explored various liquid crystal phases, but detailed interfacial profiles remain an active area of research.

Purpose of the Study:

To investigate the structure and thermodynamics of interfaces between coexisting liquid-crystalline phases using a phase-field-crystal model.
To numerically calculate interfacial profiles for mean density and nematic order tensor in 2D.
To analyze the dynamic relaxation of interfacial profiles.

Main Methods:

Utilized a 2D phase-field-crystal model.
Numerically calculated interfacial profiles for mean density and nematic order tensor.
Simulated dynamic relaxation of order-parameter profiles.

Main Results:

Identified various possible coexistences between liquid-crystalline phases, including plastic triangular crystal (PTC).
Found that the nematic order parameter interface width is larger than the mean-density interface width.
Observed that mean density decreases before the nematic order parameter when approaching from the PTC side.

Conclusions:

The study provides detailed insights into the structure and dynamics of liquid-crystal interfaces.
The findings offer a theoretical basis for understanding phase coexistence and interfacial phenomena.
Predictions can be experimentally verified using colloidal dispersions.
