resuspension

The scientist performs a resuspension of the pellet in the vial.

Definition

Noun: 1. The process or act of suspending particles again: A renewed suspension of insoluble particles in a liquid after they have previously settled or been precipitated. This term is primarily used in scientific contexts, such as chemistry, biology, and environmental science, to describe the re-dispersion of settled material.

Usage

The word "resuspension" is a technical noun. It is used to describe a specific physical process where particles that have settled at the bottom of a liquid are stirred up and mixed back into the liquid, returning them to a suspended state. * It is often used in passive constructions (e.g., "The resuspension of sediment...") or to name the process itself (e.g., "Resuspension can affect water clarity."). * It is commonly modified by adjectives specifying the type of particles (e.g., sediment resuspension, particle resuspension) or the cause (e.g., wind-induced resuspension, mechanical resuspension).

Examples
  • The storm caused the resuspension of fine sediments in the lake, making the water turbid.
  • In the laboratory protocol, gentle vortexing is used for the resuspension of the cell pellet in the new buffer solution.
  • Resuspension of dust in the air can be a significant problem during demolition work.
  • Scientists are studying the factors that control the resuspension of contaminated particles from riverbeds.
Advanced Usage
  • Resuspension is a key concept in fluid dynamics and sedimentology, often discussed in relation to shear stress and critical erosion thresholds.
  • In pharmaceutical manufacturing, achieving complete resuspension of an active powder in a suspension is critical for ensuring dose uniformity.
Variants and Related Words
  • Resuspend (verb): To cause particles to go back into suspension.
    • After centrifugation, you must resuspend the pellet in 1 mL of saline.
  • Suspension (noun): The state in which particles are dispersed throughout a fluid.
  • Resuspended (adjective): Describing particles that have undergone resuspension.
    • The resuspended material was then analyzed.
Synonyms
  • Re-dispersion
  • Re-suspension (less common variant spelling)
Related Phrases
  • Sediment resuspension: The most common collocation, referring specifically to the stirring up of settled soil, sand, and silt from the bottom of a water body.
  • Particle resuspension: A more general term for any small solid particles being mixed back into a fluid.
