Colloids and Suspensions01:17

Colloids and Suspensions

3.0K
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Chirality in Nature02:30

Chirality in Nature

16.5K
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid.

Uniform Depth Channel Flow: Problem Solving

417
To calculate the flow rate for a trapezoidal channel, first, identify the bottom width, side slope, and flow depth of the channel. The cross-sectional area (A) corresponding to the depth of flow (y), channel bottom width (B), and side slope (θ) is determined by:Next, calculate the wetted perimeter, which includes the bottom width and the sloped side lengths in contact with the water. Using the values of the cross-sectional area and the wetted perimeter, determine the hydraulic radius by...

Uniform Depth Channel Flow01:27

Uniform Depth Channel Flow

517
Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

Area of Science:

  • Active matter physics
  • Non-equilibrium statistical mechanics
  • Collective behavior in biological and artificial systems

Background:

  • Motility-induced phase separation is a known phenomenon in active matter.
  • Biological systems display complex collective behaviors due to information exchange.
  • Quorum sensing in biology involves density-dependent communication.

Purpose of the Study:

  • Investigate collective dynamics in a 2D active suspension with density-dependent chiral switching.
  • Explore transitions between uniform, phase-separated, and hyperuniform states.
  • Analyze the role of nonreciprocal interactions in emergent behaviors.

Main Methods:

  • Numerical simulations of a 2D active suspension.
  • Modeling particle chirality switching based on local density within a visual cone.
  • Tuning parameters like visual cone range and aperture.

Main Results:

  • The system transitions between uniform, phase-separated, and hyperuniform states by adjusting visual cone parameters.
  • Phase separation is accompanied by stationary edge currents and hyperuniformity in dense regions.
  • Nonreciprocal interactions, even with minimal passive/active particle mixtures, drive sustained edge currents.

Conclusions:

  • Nonreciprocal interactions, inspired by quorum sensing, can induce novel collective behaviors like edge currents and hyperuniformity in active matter.
  • These findings offer insights into biological collective dynamics and potential applications in designing artificial systems.
  • The study highlights the importance of information exchange in active matter systems beyond simple steric interactions.
