Kinetics as well as the evolution of the agarose gel topology is discussed, and the agarose gelation mechanism is identified. Aqueous high melting (HM) agarose solution (0.5% w/v) is used as the model system. It is found that the gelation process can be clearly divided into three stages: induction stage, gelation stage, and pseudoequilibrium stage. The induction stage of the gelation mechanism ...

The various molecular weight (MW) regenerated silk fibroins were prepared with different dissolution condition and the effect of MW on the gelation behavior of regenerated aqueous silk fibroin (SF) solution was investigated. The result of gelation time measurement indicated that the gelation of SF aqueous solution was accelerated by the increase of MW and SF concentration. When formic acid was ...

-Gelation and precipitation are two possible outcomes for the polymerization of monomers dissolved in a solvent. Gelation is obtained when the polymers

in this paper, polyacrylamide/chromium acetate gel polymer system was prepared as water shut-off system to control water production in one of the iranian oil reservoirs condition. effect of various parameters such as temperature (90 °c) and water formation from view point of salinity and divalent cations, was evaluated on the gelation kinetic and gel strength using bottle testing method. the re...

Studies on the functionality of muscle proteins in gelation mechanisms of structured meat products during the last three decades are briefly reviewed. Among muscle proteins, myosin is primarily the most important protein for gelation, whereas actin plays a complementary role in gelation when it coexists with myosin. The combined data of gelation and denaturation indicate that the gelation of my...

The main objective of the study was to design a non-condensing polymeric microspherebased gene delivery system for targeting macrophages. An external gelation technique was used to prepare plasmid DNA-encapsulated calcium alginate microspheres. The microspheres were characterized for particle size, surface charge, surface morphology, and DNA loading efficiency. Stability of encapsulated DNA was...

We developed a novel fabrication technique of titania microspheres utilizing a robust external gelation method on an oil/hydrogel interface. By putting sodium alginate droplets on an interface between oil and Ca 2+ -loaded hydrogel, surfactant dissolved in oil forms amphiphilic bilayer. Water molecules and calcium ions transfer through this amphiphilic bilayer. As a result, alginate droplets sh...
