Kinetics of gelation in photoreversible gels
… kinetics in these photoreversible systems. The gelation process can be considered to consist of photoreaction, micelle formation, and possibly polymer relaxation. It was found that the photon flux through the material limits the rate of reaction, which then controls the remaining processes in …

Multiscale probing of colloidal gelation dynamics
… colloidal particles in the early phase of gelation, by extending the applicability of Differential Dynamic Microscopy (DDM) to non-ergodic media. We demonstrate uncoupled development of the structure and dynamics that reveals an intermediate stage of gel formation, and compare the DDM …

Contemporary Problems in Aerosol Aggregation and Gelation
… aggregation leads to the phenomenon of gelation at a micrometer level, in which the submicron DLCA aggregates with a characteristic Df ≈ 1.8 jam together to form volume spanning gels with a characteristic Df ≈ 2.5. These aerosol gel particles, sometimes called superaggregates, have been …

Gelation Kinetics of Fumed Silica-Alcohol Suspensions
Aggregation and gelation kinetics of fumed silica were investigated by altering the solvent-surface interactions. Native and surface-modified (hydrophobic) fumed silica particles were dispersed in short-chain linear alcohols. Based on the kinetics of aggregation and gelation, it is shown that the …

Gelation Characteristics of Illinois Soybean Beverage Base
Tofu, being the most important source of protein in the Orient, is gaining popularity throughout the world. The Oriental method of producing soymilk for making tofu resulted in beany flavor, low protein and total solids recoveries, and waste treatment problems. Soybean beverages made from whole …

Kinetics of Crystallization and Gelation in Colloidal Suspensions
The competition between crystallization and gelation in colloidal suspensions is addressed as arising from three underlying processes at the particle level, viz., aggregation, dissociation, and rearrangement. Particles aggregate via Brownian encounters into clusters that have open structures. …

Engineering gelation in metal ion cross-linked hydrogels
Inspired by their role in the extraordinary mechanical properties of aquatic mussel threads, reversible metal ion cross-links have been utilized to engineer the toughness, stress relaxation, and healing ability of polymer hydrogel networks. Such transient network hydrogels are easily made by …

Elucidating Dual Methylcellulose-and-Oil-Nanoemulsion Thermoresponsive Gelation
… This represents a unique system in which two gelation regimes with distinct identity and behavior are tuned using only nanoemulsion volume fraction. This behavior is made possible by the unique fact that the component which stabilizes the nanoemulsion, methylcellulose, is also active in the …

Self-Assembly and Gelation Behaviour of Pyridyl Urea Complexes
Bis(3-pyridyl)ureas with ethylene, propylene, butylene, phenylene and napthy- lene spacer groups were synthesised by the reaction of 3-isocyanato-pyridine, pre- pared in situ from nicotinoyl azide, with the appropriate diamine. Each ligand was crystallised and their structures were solved using …

A study of the gelation of air-setting refractory mortars
… mortar was found to be helpful in overcoming the gelation but these tended to lower the refractoriness of the mortar.</p> <p>A study was made of the base exchange capacities of the dry materials and the material with the highest base exchange capacity was found to contribute more to the gelation …

Aggregation and gelation characteristics of high protein dairy ingredient powders
… and a range of functionalities including rennet gelation, heat stability, ethanol stability and acid gelation, which influence the manufacture and stabilization of the foods. The protein dispersed in water is typically subjected to various processes, including concentration, homogenization, …

Visible Light Cured Thiol-vinyl Hydrogels with Tunable Gelation and Degradation
… (NVP) was used to accelerate gelation kinetics. The gelation rate could be tuned by changing the concentration of eosinY or NVP. Variation of thiol concentration affected degradation rate of hydrogels. Many bioactive motifs have been immobilized into hydrogels to enhance cell …

Critical Properties of the Emergent Random Solid in Vulcanization/gelation Transition
The vulcanization/gelation transition is a continuous equilibrium phase transition from a liquid state to a random solid state, controlled by the density of permanent crosslinks between the constituent particles. The emergent random solid state is characterized by nonzero shear rigidity and …

Comparison of thermal gelation properties of pork, beef, fish, chicken and turkey
… thigh (TT), and catfish fillets were obtained. Gelation properties of muscle (10% protein at pH 5.5, 6.0, 6.5, or 7.0 and cooked at 0.7$\sp\circ$C or 3$\sp\circ$C/min to 70$\sp\circ$C) and myofibril (5, 7, or 10% protein at pH 6.0 and cooked at 0.7$\sp\circ$C/min to 70$\sp\circ$C) of all species …
