Colloids

21.1K
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 that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...

Electric Field

12.8K
Consider two point charges, each exerting Coulomb force on the other. It is possible to describe the Coulomb interaction via an intermediate step by defining a new physical quantity called the electric field.
In the new picture, imagine that the first charge sets up an electric field independent of all other charges in the universe. When another charge comes in its vicinity, the second charge experiences an electric force depending on the electric field at that point. The source charge does not...

Finding Electric Potential From Electric Field

5.6K
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where calculating the electric field is more straightforward than finding the potential, the electric field is used to calculate the system's potential. For a positive charge, the electric field is radially outward, and the potential is positive at any finite distance from the positive charge. In such an electric field, the motion away from the...

Determining Electric Field From Electric Potential

5.0K
The electric field and electric potential are related to each other. If the electric field at various points in the region of interest is known, it can be used to calculate the electric potential difference between any two points. Similarly, if the electric potential is known for various points, then it is possible to calculate the electric field.
In general, regardless of whether the electric field is uniform, it points in the direction of decreasing potential because the force on a positive...

Electric Field Inside a Conductor01:20

Electric Field Inside a Conductor

7.4K
When a conductor is placed in an external electric field, the free charges in the conductor redistribute and very quickly reach electrostatic equilibrium. The resulting charge distribution and its electric field have many interesting properties, which can be investigated with the help of Gauss's law.
Suppose a piece of metal is placed near a positive charge. The free electrons in the metal are attracted to the external positive charge and migrate freely toward that region. This region then...

Electric Field Lines01:25

Electric Field Lines

9.6K
The three-dimensional representation of the electric field of a positive point charge requires tracing the electric field vectors, whose lengths decrease as the square of their distance from the charge and which point away from the charge at each point. This vector field is no doubt challenging to visualize. The visualization of electric fields becomes quickly intractable as the number of charges increases.
The solution to this problem is to use electric field lines, which are not vectors but...

Summary
This summary is machine-generated.

The stability of carbon black suspensions significantly alters electric field-induced drop breakup. Stable suspensions behave like surfactant-only drops, while unstable ones exhibit faster, complex, three-dimensional breakup patterns.

Area of Science:

  • Fluid dynamics
  • Colloid science
  • Electrohydrodynamics

Background:

  • Electric fields induce fluid drop deformation and breakup.
  • Colloidal suspensions can alter fluid properties and behavior.
  • Surfactants influence interfacial tension and drop stability.

Purpose of the Study:

  • Investigate electric field-induced breakup of squalane drops with carbon black suspensions.
  • Determine the effect of colloidal suspension stability on drop breakup modes.
  • Compare breakup phenomena between stable and unstable suspensions, and with surfactant-only drops.

Main Methods:

  • Experimental study of squalane drops in silicone oil under electric fields.
  • Inclusion of carbon black particles and polyisobutylene succinimide (OLOA 11000) surfactant.
  • Axisymmetric boundary integral computations for mechanistic elucidation.

Main Results:

  • Stable carbon black suspensions showed similar breakup modes to surfactant-only drops (lobe formation, non-axisymmetric breakup at higher fields).
  • Unstable suspensions exhibited drastically different, faster breakup with asymmetric lobes, finger formation, and 3D disintegration.
  • Pure squalane drops and surfactant-only drops served as comparative bases.

Conclusions:

  • Colloidal stability on the timescale of drop deformation critically impacts electric field-induced breakup.
  • Unstable suspensions lead to complex, inhomogeneous, and rapid drop disintegration.
  • This study reveals rich and unexplored breakup phenomena influenced by colloidal stability.
