Capillary Exchange01:28

Capillary Exchange

The cardiovascular system's chief role is to disseminate gases, nutrients, waste, and other substances to the body's cells. Small molecules like gases, lipids, and lipid-soluble substances directly diffuse through capillary wall endothelial cell membranes. Glucose, amino acids, and ions, including sodium, potassium, calcium, and chloride, use transporters for facilitated diffusion via membrane-specific channels. Glucose, ions, and bigger molecules may also pass through intercellular clefts.
Capillary Electrophoresis: Instrumentation01:20

Capillary Electrophoresis: Instrumentation

Capillary electrophoresis instrumentation typically consists of several key components. A high-voltage power supply generates the electric field necessary for the separation by connecting to an anode (the positively charged electrode) and a cathode (the negatively charged electrode) located in buffer reservoirs at each end of the capillary tube. The system includes a sample vial, a fused silica capillary tube coated with polyimide for mechanical strength through which the sample components...
Capillary Beds01:20

Capillary Beds

Capillary beds are networks of tiny blood vessels that play a crucial role in the circulatory system. These beds are where the exchange of gases, nutrients, and waste products occurs between the blood and surrounding tissues. Each capillary bed consists of numerous capillaries, which are the smallest blood vessels in the body, typically only one cell-thick. This thinness allows for the efficient diffusion of substances.
Capillaries connect arterioles, small branches of arteries, to venules,...
Capillary Electrophoresis: Applications01:30

Capillary Electrophoresis: Applications

Capillary electrophoretic separations offer various modes, each with unique applications. These modes include capillary zone electrophoresis, capillary gel electrophoresis, capillary array electrophoresis, capillary isoelectric focusing, capillary isotachophoresis, micellar electrokinetic chromatography, and capillary electrochromatography.
Capillary zone electrophoresis (CZE) separates ionic components based on their electrophoretic mobility. It has been used to separate proteins, amino acids,...
Electrophoresis: Overview01:20

Electrophoresis: Overview

Electrophoresis is a powerful analytical separation technique that relies on the differential migration of charged species when subjected to an electric field. The core strength of electrophoresis lies in its ability to separate high-molecular-weight species in complex mixtures. It has found widespread use in biochemistry, molecular biology, and analytical chemistry, allowing the separation of compounds like amino acids, nucleotides, carbohydrates, and proteins with excellent resolution.

Rise of Liquid in a Capillary Tube01:18

Rise of Liquid in a Capillary Tube

When very thin cylindrical tubes, called capillaries, are dipped in a liquid, the liquid rises or falls in the tube compared to the surrounding liquid. This phenomenon is called capillary action. Capillary action occurs due to the combination of two opposing forces: the cohesive forces of the liquid, which cause it to stick to itself and form a rounded shape, and the adhesive forces between the liquid and the walls of the container, which cause the liquid to be attracted to the container walls.

Area of Science:

  • Fluid dynamics
  • Interfacial phenomena
  • Capillary flow

Background:

  • Nonwetting liquid slugs in capillary tubes are inherently unstable.
  • Instability leads to rapid, complete liquid extraction upon minor disturbance.

Purpose of the Study:

  • Investigate the dynamics of nonwetting slug extraction from capillary tubes.
  • Analyze two limiting viscosity cases: slug viscosity greater than and less than the surrounding liquid.
  • Identify dominant dissipation mechanisms and extraction dynamics.

Main Methods:

  • Experimental manipulation of drop and tube length.
  • Theoretical modeling of fluid extraction dynamics.
  • Analysis of two distinct viscosity regimes.

Main Results:

  • Characterized the instability-driven extraction of nonwetting slugs.
  • Identified the dominant energy dissipation mechanisms for each viscosity case.
  • Developed a theoretical description matching experimental observations.

Conclusions:

  • The extraction dynamics are highly dependent on the relative viscosities of the slug and surrounding liquid.
  • Dissipation mechanisms vary significantly between the two studied viscosity cases.
  • Understanding these dynamics is crucial for controlling liquid transport in microfluidic devices.
