gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. high specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. they are made by addition a suitable gellant to liquid propellants. in this research, nano al particles have been used in udmh gel fuel. the gel...

Acetaminophen is used as an analgesic and antipyretic agent. The aim of the study was evaluation of the effect of different polymers on rheological behavior of acetaminophen suspension. In order to achieve controlled flocculation, sodium chloride was added. Then structural vehicles such as carboxymethyl cellulose (CMC), polyvinyl pyrrolidone (PVP), tragacanth, and magnesium aluminum silicate (V...

The ability of pea protein isolates (PPI) to form complex coacervates with tragacanth gum was investigated. coacervate formation structurally compared three other PPI-polysaccharide interaction models: arabic and sodium alginate (known PPI) tara gum, a galactomannan. effects the pH protein/polysaccharide ratio were mainly investigated using turbidity zeta potential measurements. Regarding solub...

Background: The excellent biocompatibility, biodegradability and biological properties of the hydrogels, fabricated using natural polymers, especially polysaccharides, are very advantageous for biomedical applications. Gum tragacanth (GT) is a heterogeneous highly branched anionic polysaccharide, which has been used extensively in food and pharmaceutical industries. Despite,  its desirable prop...

We introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (GT), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems. The modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-APA) by means of Escherichia coli ATCC11105 with penicillin G ...
