Simulation of Scattering Properties of Gels

Macromolecules, 1999
Brownian dynamics simulations of a simple model of a polymer gel were performed to investigate the conditions under which gels show nonergodicity, the presence of frozen density fluctuations which do not relax completely, and to explore possible connections between nonergodicity and the existence of density fluctuations of large spatial extent which ...

Viscoelastic Properties of Particle Gels

Journal of Colloid and Interface Science, 1999
The effect of strength of attraction and volume fraction on the mechanical properties of alumina particle networks were investigated. Alumina particle gels were formed reversibly and in situ in the rheometer by cooling alumina particle suspensions with adsorbed poly(12-hydroxy stearic acid) suspended in a marginal solvent, hexanol.

Thromboresistant properties of hydrophilic gels

Bulletin of Experimental Biology and Medicine, 1980
Thromboresistant properties of hydrophilic gels prepared on the basis of copolymers of nitrogen-containing heterocyclic vinyl compounds with vinyl monomers have been investigated. Hydrophilic gels prevent fibrinogen adsorption, activation of procoagulants and adhesion of platelets. Hydrogel surfaces possess selective tropism for plasma albumin.

Rheological properties of contraceptive gels

Contraception, 2000
The rheological properties of 4 commercially available contraceptive drug delivery gels and their dilutions with a vaginal fluid simulant were measured. These properties govern the critical functions of spreading and retention of these gels over the vaginal surfaces.

Scattering Properties of Dipolar Gels

Macromolecules, 2008
We study the effects of dipolar interactions of polymer chains where the dipolar moments are aligned along the polymer segments on the scattering properties of dipolar gels made by randomly cross-linking dipolar chains in polar solvent. Using the field-theoretical approach, the dipolar interactions of polar solvent and dipolar polymer segments are ...

Rheological properties of topical fluoride gels

Dental Materials, 1989
The rheological properties of several commercial topical fluoride gels were studied. For that purpose, we investigated hysteresis loops under standard conditions, equilibrium values, apparent viscosities as a function of shear rate, rate of thixotropic recovery, and the influence of temperature.

The rheological properties of carbopol gels II. Oscillatory properties of carbopol gels

International Journal of Pharmaceutics, 1979
Abstract Viscoelastic properties of aqueous Carbopol gels were examined at frequencies of 7.91 × 10 −3 to 25 Hz using a Weissenberg rheogoniometer. Neutralized gels changed little from 10 to 50dgC and were similar to unneutralized gels. Data confirmed the dominant elastic nature of Carbopol gels (phase lags of 2–14°) and the relative small change of

Rheological properties of casein gels

Journal of Dairy Research, 1989
SummaryThe rheological properties of rennet-induced skim milk gels at 30 °C are compared with casein gels formed by acidification to pH 4·6 at 2 °C and subsequent heating to 30 °C. Both types of gels are viscoelastic. However, the gels formed by rennet action are relatively more viscous over time scales longer than 1 s. This implies that on average the

Fracture properties of starch gels

1992
Abstract Fracture properties of starch gels are, in contrast with their small deformation properties, clearly time dependent. Fracture stress and deformation at fracture increased with increasing rate of deformation. A possible explanation for this is friction between the granules during large deformations.
