• collagen
  • Gelatin, a bipolymer, is produced through the hydrolysis of collagen. (wikipedia.org)
  • Gelatin or gelatine (from Latin: gelatus meaning "stiff", "frozen") is a translucent, colorless, brittle (when dry), flavorless food derived from collagen obtained from various animal body parts. (wikipedia.org)
  • Gelatin is an irreversibly hydrolyzed form of collagen, wherein the hydrolysis results in the reduction of protein fibrils into smaller peptides, which will have broad molecular weight ranges associated with physical and chemical methods of denaturation, based on the process of hydrolysis. (wikipedia.org)
  • While many processes exist whereby collagen may be converted to gelatin, they all have several factors in common. (wikipedia.org)
  • agar
  • After it is freeze-dried to remove the water, it is left as a honeycomb of dried agar filled with air, with cell sizes two to three micrometers (2-3 µm) in diameter. (wikipedia.org)
  • tissue
  • Water exchange of parenchymatous tissue, namely liver, kidney, or pancreas, occurs by osmosis, and the movement of water, as is well known, occurs in direct relation to the concentration of the surrounding solution. (rupress.org)
  • Dense collagenous tissue, apparently impervious to the movement of water, exhibits a conspicuous ability to attract and hold it. (rupress.org)
  • Gelatin microparticles also serve as enhancers of calcium deposition, which serves as an indicator of tissue regeneration. (wikipedia.org)
  • In the original version of the printing process, carbon tissue (a temporary support sheet coated with a layer of gelatin mixed with a pigment-originally carbon black, from which the name derives) is bathed in a potassium dichromate sensitizing solution, dried, then exposed to strong ultraviolet light through a photographic negative, hardening the gelatin in proportion to the amount of light reaching it. (wikipedia.org)
  • Carbon tissue, a layer of unsensitized pigmented gelatin on a thin paper support sheet, was introduced by British physicist and chemist Joseph Swan in 1864. (wikipedia.org)
  • To make a full-color print, three negatives photographed through red, green and blue filters are printed on dichromate-sensitized sheets of pigmented gelatin (traditionally called "carbon tissue" regardless of the pigment incorporated) containing, respectively, cyan, magenta and yellow pigments. (wikipedia.org)
  • Ballistic gelatin is a testing medium scientifically correlated to swine muscle tissue (which in turn is comparable to human muscle tissue), in which the effects of bullet wounds can be simulated. (wikipedia.org)
  • While ballistic gelatin does not model the structure of the body, including skin and bones, it works fairly well as an approximation of tissue and provides similar performance for most ballistics testing. (wikipedia.org)
  • Ballistic gelatin is used rather than actual muscle tissue due to the ability to carefully control the properties of the gelatin, which allows consistent and reliable comparison of terminal ballistics. (wikipedia.org)
  • Since ballistic gelatin mimics the properties of muscle tissue, as compared to porcine muscle tissues, it is the preferred medium for comparing the terminal performance of different expanding ammunition, such as hollow point and soft point bullets. (wikipedia.org)
  • These bullets use the hydraulic pressure of the tissue or gelatin to expand in diameter, limiting penetration and increasing the tissue damage along their path. (wikipedia.org)

  • Carbon printing is based on the fact that gelatin, when sensitized to light by a dichromate, is hardened and made insoluble in water when exposed to ultraviolet light. (wikipedia.org)
  • This first solution to this problem, found by Agfa workers Gustav Wilmanns and Wilhelm Schneider, was creating a print made of three layers of gelatin containing subtractive color dye couplers made of long hydrocarbon chains, and carboxylic or sulfonic acid. (wikipedia.org)

  • rinse

  • A rinse with clean water may be substituted. (wikipedia.org)
  • In very hard water areas, a pre-rinse in distilled water may be required - otherwise the final rinse wetting agent can cause residual ionic calcium on the film to drop out of solution, causing spotting on the negative. (wikipedia.org)
  • micelles
  • Bonds between hydrophobic sites start to develop and are enforced by calcium bonds which form as the water molecules in the micelles start to leave the structure. (wikipedia.org)
  • This turned the dye couplers into micelles which can easily be scattered in the gelatin while loosely tethering to it. (wikipedia.org)
  • sugars
  • Mixing with other biopolymers and crosslinking by sugars may improve functional properties of fish gelatin. (sinaweb.net)
  • combine
  • This avoided the labour-intensive extraction process, but it did require industrial methods to combine the gelatin and corn starch in the right way. (wikipedia.org)
  • uniform
  • Film may be rinsed in a dilute solution of a non-ionic wetting agent to assist uniform drying, which eliminates drying marks caused by hard water. (wikipedia.org)
  • stable
  • Gelatin can be manipulated to form a stable matrix for biologically reactive compounds, allowing for the incorporation and protection against enzymatic degradation. (wikipedia.org)
  • At the same time, candy makers began to replace the mallow root with gelatin which created a stable form of marshmallow. (wikipedia.org)
  • molecules
  • In dentistry, syneresis is the expulsion of water or other liquid molecules from dental impression materials (Alginate for example) after an impression has been taken. (wikipedia.org)
  • The opposite process of syneresis is imbibition, meaning, a material that absorbs water molecules from the surrounding. (wikipedia.org)
  • form
  • Gelatin microparticles have also been incorporated to form 3D scaffolding systems through aggregation "in vitro" while also performing known use as a molecule delivery system. (wikipedia.org)
  • They are composed of three layers of gelatin, each containing a light-sensitive material and a different dye coupler of subtractive color that together form a full-color image. (wikipedia.org)
  • amount
  • It is chilled to 4 °C (39 °F). The older NATO formula specifies a 20% solution, chilled to 10 °C (50 °F), but that solution costs more to prepare, as it uses twice the amount of the gelatin. (wikipedia.org)
  • The worldwide production amount of gelatin is about 375,000-400,000 tonnes per year (830×10^6-880×10^6 lb/a). (wikipedia.org)
  • solution
  • After printing, the solution is allowed to dry up and the DNA-gelatin is stuck tightly in position on the array. (wikipedia.org)
  • First, adhesive from the HybriWell is peeled off and the HybriWell is attached over the area of the slide printed with the gelatin-DNA solution. (wikipedia.org)
  • final
  • The three images are then transferred, one at a time, onto a final support such as a heavy sheet of smooth gelatin-sized paper. (wikipedia.org)
  • fish
  • Fish by-products may also be used because they eliminate some of the religious obstacles surrounding gelatin consumption. (wikipedia.org)
  • Method
  • Water in water (w/w) emulsification is the most popular method of production. (wikipedia.org)
  • In his book Bullet Penetration, ballistics expert Duncan MacPherson describes a method that can be used to compensate for ballistic gelatin that gives a BB penetration that is off by several centimeters (up to two inches) in either direction. (wikipedia.org)
  • rather
  • In an important early 20th century variation of the process, known as carbro (carbon-bromide) printing, contact with a conventional silver bromide paper print, rather than exposure to light, was used to selectively harden the gelatin. (wikipedia.org)
  • replace
  • Since the 1990s, manufacturers have been able to replace gelatin in the shell with other polymers based on, for example, starch and carrageenan. (wikipedia.org)
