The paper tests the influence of mass fractions of carbonyl iron particles (CIPs) on the rheological properties of magnetorheological (MR) gels. Polyurethane-based MR gels with different weight fraction of CIPs, i.e., 40, 60, and 80%, were firstly prepared by mechanical mixing, respectively. The changes of shear stress and viscosity with shear rate under different magnetic flux density were

The rheological properties of the gels were determined by oscillatory viscometry at a stress range of 0 - 100 Pa and a frequency of 0.05 Hz using a 1 mm gap. The dynamic moduli of gels filled with particles have been studied as a function of the volume fraction of dispersed particlesϑ f (0–0.4) and of the way in which they interact with the gel matrix. Two gels of different nature were studied, viz. polyvinyl alcohol (PVA) — Congo red gels (a so-called rubber gel) and casein gels made by acidification of skimmed milk. Emulsion droplets Rheological properties of acid skim milk gels as affected by the spatial distribution of the structural elements and the interaction forces between them. International Dairy Journal 2008, 18 (5) , 585-593. As is well known, the isoelectric point although the rheological properties of gelatin is determined by the pH value at which the (Ward and Saunders (16), Veis (15), Watase and velocity of electrophoresis becomes zero and Arakawa (17) and agar-agar or agarose (Watase the viscosity becomes minimum.

Ring 2 In particular, the gelling properties of zein promote the formation of a porous network, which can be easily used for the controlled leakage of the entrapped bioactive compounds. Several studies have described the rheological behavior of speciﬁc fractions of zein such as - and -zein dispersions, It is shown that upon exceeding the certain shear rate value gels demonstrate abnormal rheological property (instant flow cessation). Dependence of shear stress and dynamic viscosity of Gel 1 on 2017-04-10 · A correlation was shown between the results of the rheological properties and the barrier properties of the gels. This confirms the possibility of monitoring the quality of the gels at the stage of recipe development. CONCLUSIONS: Polyacrylates are viable for use in industry to produce hydrophilic barrier creams suitable for skin protection.

Rheological behavior of vaginal gels strongly depended on the type of gelling agent used, which potentially influences their spreading and retention properties when administered in the vaginal canal. Small variations in gels composition can result in substantial changes in their features, namely viscosity, yield stress and thixotropy.

Although rheological properties are considered bulk and macroscopic properties, they are strongly affected by the gel chemical composition and microstructure, which depends on both covalent and physical bindings. The dynamic moduli of gels filled with particles have been studied as a function of the volume fraction of dispersed particlesϑ f (0–0.4) and of the way in which they interact with the gel matrix. Two gels of different nature were studied, viz.

Rheological analysis. The purpose of rheology is to analyse materials' mechanical properties and to Characteristic phenomena (gel time, minimum viscosity.

polyvinyl alcohol (PVA) — Congo red gels (a so-called rubber gel) and casein gels made by acidification of skimmed milk. The rheological properties of concentrated wheat starch gels were measured with shear stress relaxation experiments in cone‐plate geometry. The water content of the investigated gels were 80, 60, 50 and 30% (w/w), respectively, and the relaxation modulus (G) and half relaxation time (T 1/2) were studied after heating to different temperatures. most of rheological investigations have been focused on steady shear viscosity and sol-gel transition phenomenon. Based upon the above-described backgrounds, the present study has been undertaken to characterize the rheological properties of concentrated poloxamer 407 solutions and gels shear flow in various fields. EXPERIMENTAL SECTION The rheological properties of filled polymers are determined not only by the type and amount of filler, but also by the shape, size and size distribution of its particles.
