Because polyelectrolytes may be biocompatible, it follows that they can be used to stabilize emulsion in foods. Several studies have focused on using polyelectrolytes to induce mixing of proteins and polysaccharides in oil-in-water emulsions. DSS has been successfully used to stabilize these types of emulsions. [25]
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
To dust the emulsion side, it is best to use an unused paint brush and, very gently, brush from the center to the outside of the plate. To clean the underside of the leaf (non-emulsion side), dip a cotton ball or cotton round into a cup of distilled water, and work from the middle of the plate to the outside. Water on the emulsion side will ...
A black and white photographic print in a tray while being processed after exposure to light under a photographic enlarger. Typically three trays are used containing either developer, stop bath, or fixer, in that order.
In photography, washing is an important part of all film processing and printmaking processes. After materials have been fixed , washing removes unwanted and exhausted processing chemicals which, if left in situ, may cause deterioration and destruction of the image.
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().

Emulsions are thermodynamically unstable liquid/liquid dispersions that are stabilized. [1] Emulsion dispersion is not about reactor blends for which one polymer is polymerized from its monomer in the presence of the other polymers; emulsion dispersion is a novel method of choice for the preparation of homogeneous blends of thermoplastic and elastomer.
