Phase Diagrams02:39

Phase Diagrams

50.4K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

Phase Transitions: Melting and Freezing

15.3K
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...

Subatomic Particles

113.8K
Dalton was only partially correct about the particles that make up matter. All matter is composed of atoms, and atoms are composed of three smaller subatomic particles: protons, neutrons, and electrons. These three particles account for the mass and the charge of an atom.

Phase Transitions

23.3K
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...

The Nucleosome Core Particle02:10

The Nucleosome Core Particle

14.6K
Nucleosomes are the DNA-histone complex, where the DNA strand is wound around the histone core. The histone core is an octamer containing two copies of H2A, H2B, H3, and H4 histone proteins.
The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...

Inductance: Single-Phase And Three-Phase Line01:28

Inductance: Single-Phase And Three-Phase Line

641
Understanding the inductance of transmission lines is crucial for efficient design and operation in electrical power systems. This discussion delves into the inductance characteristics of single-phase two-wire and three-phase three-wire transmission lines with equal phase spacing.
Single-Phase Two-Wire Line:
A single-phase line consists of two solid cylindrical conductors, denoted as x and y. Each conductor carries phasor currents ix and iy, respectively. Given that the sum of these currents is...

Summary

Self-propelled particles phase separate when collision time (τC) exceeds time between collisions (τF). This new model predicts phase separation onset in systems with reduced noise.

Area of Science:

  • Physics
  • Statistical Mechanics
  • Soft Matter

Background:

  • Self-propelled particles exhibit phase separation into dense and dilute regions above a critical density.
  • Existing theories struggle to predict phase separation in low-noise environments.

Purpose of the Study:

  • To develop a predictive model for self-propelled particle phase separation, particularly in low-noise conditions.
  • To identify the key timescales governing the onset of phase separation.

Main Methods:

  • Developed a model based on two density-dependent timescales: τF (time between collisions) and τC (collision lifetime).
  • Employed analytical calculations and active particle simulations.
  • Measured timescales and determined critical densities in 2D and 3D.

Main Results:

  • Phase separation occurs when the mean time between collisions (τF) is less than the mean collision lifetime (τC).
  • The model successfully predicts the critical density for phase separation.
  • Timescales were accurately measured in simulations.

Conclusions:

  • The τF < τC criterion is essential for initiating phase separation by allowing cluster growth.
  • The new model provides a robust framework for understanding phase separation in active matter systems with reduced noise.
