emulsion

Examples of emulsion in the following topics:

• Hydrophilic and Hydrophobic Colloids

  • Energy input, through shaking, stirring, or homogenizing, is needed to form the emulsion.
  • Over time, an emulsion tends to separate, because separation puts it in a more stable state.
  • There are three types of instability in emulsions: flocculation, creaming, and coalescence.
  • In B, an emulsion of Phase II dispersed in Phase I has been formed.
  • In C, the unstable emulsion progressively separates.

• History of Photography

  • The photographic emulsions then in use were insensitive to most of the spectrum, so the result was very imperfect and the demonstration was soon forgotten.
  • It captured the red, green and blue color components in three layers of emulsion.
  • All the color films for making prints and slides currently available use the multilayer emulsion approach pioneered by Kodachrome.

• Dosimetry

  • Outside the United States, the most widely used type of personal dosimeter is the film badge dosimeter, which uses photographic emulsions that are sensitive to ionizing radiation.

• Contemporary Indian Art

  • Akbar Padamsee, a contemporary Indian artist and painter, has worked with various mediums, from oil painting, plastic emulsion, water color, sculpture, and printmaking to computer graphics and photography.

• Holography

  • One of the most common is a film very similar to photographic film (silver halide photographic emulsion), but with a much higher concentration of light-reactive grains, making it capable of the much higher resolution that holograms require.

• Photography during the Great Depression

  • These new technologies allowed for the proliferation of color photography for the first time, and currently available color films still employ a multilayer emulsion and the same principles, most closely resembling Agfa's product.

• Silver

  • The other silver halides used in the manufacture of photographic emulsions are made in the same way, using bromide or iodide salts.
