The production of silica is performed by mixing an inorganic, silicate-based precursor and an acid. Monomeric silicic acid forms and polymerizes to amorphous silica particles. Both further polymerization and agglomeration of the particles lead to a gel network. Since polymerization continues after gelation, the gel network consolidates. This rather slow process is known as “natural syneresis” a...

The PREMIER Cryptococcal Antigen Enzyme Immunoassay (Meridian Diagnostics) did not give discrepant results with rheumatoid factor, syneresis fluid, or serum macroglobulins from systemic lupus erythematosis patients. The Cryptococcal Antigen Latex Agglutination System (Meridian Diagnostics) did cross-react with syneresis fluid but not with the other serum factors tested.

Silica in industrial production processes is precipitated by mixing an acid and an inorganic precursor. In this aqueous solution, silica particles form due to a polymerization reaction and agglomeration and, finally, build a gel. Thereafter, the reaction continues, and the gel network shrinks with the expulsion of the enclosed pore liquid. This slow process is known as “natural syneresis” and s...

Purpose: To evaluate imbibition and syneresis in four commercially available irreversible hydrocolloid (alginate) impression materials at different time intervals (10, 20 and 30 minutes). Materials and methods: Eighty samples of four commercially available irreversible hydrocolloid (alginate) impression materials Algitex (DPI, Mumbai), Plastalgin (Septodont, Cedex, France), Zelgan 2002 (Dentspl...

1. When solid blocks of isoelectric gelatin are placed in cold distilled water or dilute buffer of pH 4.7, only those of a gelatin content of more than 10 per cent swell, while those of a lower gelatin content not only do not swell but actually lose water. 2. The final quantity of water lost by blocks of dilute gelatin is the same whether the block is immersed in a large volume of water or whet...

Desirability and good background of yogurt have led the manufacturers to use this product mostly for producing milk-based probiotic products. The aim of this study was to evalutate the effect of a mixture of prebiotics including oligofructose, lactulose, and inulin on physicochemical properties (pH value, acidity, and syneresis) of synbiotic yogurt containing lactobacillus casei. Pasteurized mi...

The eyes of 15 rhesus monkeys were evaluated. Various degrees of vitreal syneresis were observed in 28 of the 30 eyes. The observed vitreal structures varied from fine strands randomly spaced throughout the vitreous to thick, intertwining, fibrous networks with some clumping of the collagenous condensate at the fiber junctions. Qualitatively, the degree of syneresis was slightly more extensive ...
