Summary
Researchers discovered a new active matter state called the swirlonic state, where particles form orbiting groups called swirlons. These swirlons move predictably under force and merge slowly, unlike typical matter states.
Area of Science:
- Physics
- Soft Matter Physics
- Active Matter Physics
Background:
- Active matter systems exhibit diverse collective behaviors.
- Understanding emergent states in active matter is crucial for material science.
Purpose of the Study:
- To report the discovery of a novel swirlonic state in active matter.
- To investigate the properties and dynamics of swirlons and their interactions.
Main Methods:
- Extensive numerical simulations were performed.
- Theoretical analysis was conducted to model swirion behavior.
- Comparison of simulation results with theoretical predictions.
Main Results:
- A novel swirlonic state, composed of orbiting active particles (swirlons), was identified.
- Swirlons exhibit viscous-like motion under external load and slow coalescence.
- Gaseous, liquid, and solid states were observed, with unique non-coexistence of liquid and gaseous phases.
Conclusions:
- The swirlonic state represents a new paradigm in active matter physics.
- The unique phase behavior, particularly the non-coexistence of liquid and gaseous states, is attributed to the absence of fast particles.
- Theoretical models accurately predict the observed simulation results, validating the findings.

100.2K
Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

01:20States of Matter
2.4K
Solids, liquids, and gases are the three states of matter commonly found on Earth. A solid is rigid and possesses a definite shape. A liquid flows and takes the shape of its container, except it forms a flat or slightly curved upper surface when acted upon by gravity. Both liquid and solid samples have volumes nearly independent of pressure. A gas takes both the shape and volume of its container.

Irrotational flow is characterized by fluid motion where particles do not rotate around their axes, resulting in zero vorticity. For a flow to be irrotational, the curl of the velocity field must be zero. This imposes specific conditions on velocity gradients. For instance, to maintain zero rotation about the z-axis, the gradient condition:

3.1K
The internal energy of a substance—the total kinetic energy of all its molecules and the potential energy of their associated forces—depends on the strength of the intermolecular forces in the condensed phases and the pressure exerted on the substance. The internal energy of a substance is the highest in the gaseous state, the lowest in the solid state, and intermediate in the liquid state. Phase transitions are caused by changes in physical conditions, such as temperature and...

15.0K
Scientists identified the plasma membrane in the 1890s and its principal chemical components (lipids and proteins) by 1915. The model for plasma membrane structure, proposed in 1935 by Hugh Davson and James Danielli, was the first model to be widely accepted in the scientific community. The model was based on the plasma membrane's "railroad track" appearance in early electron micrographs. Davson and Danielli theorized that the plasma membrane's structure resembled a sandwich...

01:34The Fluid Mosaic Model
173.7K
The fluid mosaic model was first proposed as a visual representation of research observations. The model comprises the composition and dynamics of membranes and serves as a foundation for future membrane-related studies. The model depicts the structure of the plasma membrane with a variety of components, which include phospholipids, proteins, and carbohydrates. These integral molecules are loosely bound, defining the cell’s border and providing fluidity for optimal function.
