The rheological properties of sputum
Biorheology, 1969Mucoid sputum has been examined by three different rheological techniques, continuous shear, creep and oscillation. Continuous shear experiments using a Ferranti–Shirley cone and plate viscometer, are limited in their application by the viscoelastic nature of the material.

Rheological properties of casein gels
Journal of Dairy Research, 1989SummaryThe 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

Rheological Properties of “Dry Water”
Volume 6: Fluids and Thermal Systems; Advances for Process Industries, Parts A and B, 2011This study reports the rheological properties of the novel material “dry water” which contains about 98% by weight water but resembles a dry powder. Dry water is a water-in-air inverse foam which consists of microscopic water droplets encapsulated with hydrophobic fumed-silica nanoparticles. This novel material offers a large surface to volume ratio on

Rheological properties of magnetic suspensions
Journal of Physics: Condensed Matter, 2008We present results of a theoretical study of the magnetorheological viscosity η of a suspension versus the applied magnetic field H and shear rate [Formula: see text]. It is supposed that the macroscopic rheological effects are provided by linear chain-like aggregates.

Rheological Properties of Magmas
Annual Review of Earth and Planetary Sciences, 1984Recent studies of igneous rocks have taken a refreshing new direction, mainly as the result of a greater awareness of the important role played by physical properties of magmas in determining the eruptive behavior and compositional variations of volcanic rocks.

Rheological properties of topical fluoride gels
Dental Materials, 1989The 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.

Rheological properties of micro-nano magneto-rheological fluid
Materials Express, 2019In this paper, a novel micro-nano Magneto-rheological Fluid (MR) is proposed, and its mechanical performance, mainly including the shear torque and normal stress, is studied. Here, the magnetic particle in this kind of smart fluid is composed by the micro and nano particle, that is, produced by adding some nano magnetic or nonmagnetic particles into ...

Rheological Properties of Multichain Polybutadienes
Rubber Chemistry and Technology, 1965Abstract The introduction of one or two long chain branches into a polybutadiene molecule to form trichain or tetrachain molecules, respectively, leads to profound changes in Theological behavior. At low molecular weights the Newtonian (zero shear) viscosity is decreased relative to a linear polymer of the same molecular weight.

Tissue Conditioners: II. Rheologic Properties
Journal of Dental Research, 1970The rheology of proprietary and experimental tissue conditioners was studied. Viscoelastic properties were examined to evaluate the role of ethanol in the liquid component and the effect of temperature. Experimental materials were prepared that corresponded closely to the proprietary materials in their viscoelastic properties.
