Molecular Comparison of Gases, Liquids, and Solids02:26

Molecular Comparison of Gases, Liquids, and Solids

Particles in a solid are tightly packed together (fixed shape) and often arranged in a regular pattern; in a liquid, they are close together with no regular arrangement (no fixed shape); in a gas, they are far apart with no regular arrangement (no fixed shape). Particles in a solid vibrate about fixed positions (cannot flow) and do not generally move in relation to one another; in a liquid, they move past each other (can flow) but remain in essentially constant contact; in a gas, they move...
Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility02:34

Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility

Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...
Distillation: Vapor–Liquid Equilibria01:01

Distillation: Vapor–Liquid Equilibria

Distillation is a separation technique that takes advantage of the boiling point properties of disparate elements in a mixture. To perform distillation, we begin by heating a miscible mixture of two liquids with a significant difference in boiling points (at least 20°C). As the solution heats up and reaches the bubble point of the more volatile component, some molecules of the more volatile component transition into the gas phase and travel upward into the condenser, which is a glass tube with...
Distribution of Molecular Speeds01:27

Distribution of Molecular Speeds

The motion of molecules in a gas is random in magnitude and direction for individual molecules, but a gas of many molecules has a predictable distribution of molecular speeds. This predictable distribution of molecular speeds is known as the Maxwell-Boltzmann distribution. The distribution of molecular speeds in liquids is comparable to that of gases but not identical and can help to understand the phenomenon of the boiling and vapor pressure of a liquid. Consider that a molecule requires a...
Gas Solubility01:31

Gas Solubility

Gas solubility in liquids forms liquid-gas solutions, such as soft drinks, where carbon dioxide is dissolved in water, and the ocean, where the solubility of oxygen and carbon dioxide supports marine life. The ability of oceans to dissolve gases impacts weather conditions in the troposphere.However, gas-liquid interactions vary. For instance, hydrogen chloride gas is highly soluble in water, while oxygen's solubility is much lower. Because these solutions are non-ideal, Raoult’s law, which...
Nonideal Two-Component Liquid Solutions01:29

Nonideal Two-Component Liquid Solutions

Nonideal liquid solutions, also known as real solutions, do not strictly follow Raoult's law. Raoult's law is a rule of thumb in physical chemistry. However, not all mixtures adhere to this law due to varying molecular interactions. For example, in an acetone/chloroform solution, the individual vapor pressures of the components are lower than expected, resulting in a total vapor pressure below that predicted by Raoult's law, causing a negative deviation.On the other hand, in an ethanol/water...

Summary

Active fluids can reverse the Ostwald process, forming bubbly or microphase separation. Domain size in microphase separation depends on Ostwald reversal, coalescence, and nucleation rates.

Area of Science:

  • Soft Matter Physics
  • Active Matter
  • Phase Transitions

Background:

  • Active fluids exhibit complex phase behaviors distinct from passive systems.
  • The Ostwald process, typically leading to coarsening, can be reversed in active fluids.

Purpose of the Study:

  • To investigate the mechanisms of microphase and bubbly phase separation in active fluids.
  • To understand the factors governing the size distribution of mesoscopic domains during phase separation.

Main Methods:

  • Large-scale simulations of a minimal field theory for active phase separation.
  • Development and application of an effective model focusing on domain dynamics.

Main Results:

  • Bubbly phase separation results in macroscopic regions of homogeneous and microphase-separated fluids.
  • Domain size distribution in microphase-separated fluids is determined by the interplay of Ostwald reversal, coalescence, and nucleation.
  • Domain size distributions can be narrowly peaked or broad, eventually reaching a system-size-independent cutoff.

Conclusions:

  • The dynamics of Ostwald reversal, coalescence, and nucleation are critical in controlling active fluid phase separation.
  • The study provides a framework for understanding domain formation and size selection in active soft matter systems.
