The effect of ethanol addition on the rheological and mechanical properties of calcium alginate gels was determined. Small-angle X-ray scattering and

I would like to measure the rheological properties of a gel using a rotational rheometer with a plate-plate geometry.The sample is a cylinder with diameter D and thickness h. Normally I make two

The differences in gel strength using these two media were accounted for by the difference in the extent of hydrogen bond formation between the silanol groups on the silica surface. 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. Rheological properties and microstructures of Carbopol gel network system Rheological properties of a surfactant-induced gel for the lysozyme-sodium dodecyl sulfate-water system. / Montalvo, G; Khan, Ali. I: Colloid and Polymer Science, Vol. 283, Nr. 4, 2005, s.

Rheological properties of gels

Some of the classical but important Dec 31, 2019 Gels at concentrations of 2.0%, 2.5% and 3.0% exhibit rheopexy properties at low shear rate values (0.1 s-1). Accordingly, in such systems, the Apr 27, 2017 Whereas no correlation was found between gel rheological properties and the surfactant:hyaluronan charge ratio, the properties were sensitive The influence of strain amplitude, applied coil current, CIP weight fraction and driving angular frequency on the dynamic rheological properties of MR gels are It was determined that the replacement of part of potato starch with inulin significantly modifies rheological properties of starch pastes and gels, weakening their The formation of polysaccharides gels depends on intermolecular hydrogen- bonding interactions, which are generated by intermolecular collisions. During Formation, structure and rheological properties of soy protein gels. Ph. D. thesis, Wageningen University, The Netherlands.

In the range 0<θ s < 0.4 mixed gels showed higher mechanical (E, elastic modulus) and rheological (G′, storage modulus) properties than pure gels, with maximum values for θ s = 0.2–0.3.

Each protein was tested at 8% protein concentration and heated for 0–120 min at 80°C in an agitating water bath. 2003-09-01 · Obviously, DSC and dynamic rheological testing examine different properties of the gel network. The latter shows the density of junctions zones, while the former their nature and ‘quality’ of organization.

The effect of ethanol addition on the rheological and mechanical properties of calcium alginate gels was determined. Small-angle X-ray scattering and

Here, we report the nonlinear rheological properties and failure behavior of alginate hydrogels, a class of polysaccharide hydrogels, synthesized via ionic and covalent crosslinking. PDF | Long-chained surfactant solutions have found widespread use in the oil and gas industry due to a host of attractive properties. In this paper, we | Find, read and cite all the research Gels are soft-elastic materials consisting of a three-dimensional crosslinked polymer network and liquid filling the space between this network. Numerous gels with unique physical properties have Notably, by increasing temperature over T g, the rheological properties of these gels can be tuned in a wide range. Careful engineering of the block copolymer composition later led to a patented material, commercially known as Mebiol Gel, whose mechanical strength and permeability at physiological temperature are highly suitable for cell growth

1 Dec 1988 DSC and dynamic viscoelastic measurements were carried out for agarose– DMSO–water gels in order to clarify the relation between the Rheological profiling offers an unparalleled insight into the sensory, handling, stability and appearance characteristics of starch-based products. These insights Cells were observed within the gels over 0–28 days, and accumulation of of mechanical and rheological properties of a cell-loaded peptide gel during ECM Carrageenan emulsion gels containing sunflower oil were prepared using Moreover, the rheological properties and the micro- and nanostructure from the Avhandlingar om RHEOLOGICAL PROPERTIES.

The effect of basil seed gum (BSG) on the rheological and physicochemical properties of heat‐induced egg albumin gels. Food Hydrocolloids , 82 , 268–277. 10.1016/j.foodhyd.2018.01.013 [ CrossRef ] [ Google Scholar ] Relation between Rheological Properties of Pectin Gels and Pectin Fine Structure Anna Ström1, Leif Lundin2, Ed Morris3 and Martin A.K. Williams4,5 1 Pharmaceutical Technology, Chemical and Biological Engineering, Chalmers University of Technology, 412 96 Göteborg, Sweden 2Food Science Australia, Private Bag 16, Werribee, Vic 3030, Australia The impact of oat β-glucan concentration and molecular weight (MW) on gel properties was investigated. Mixed MW gels/viscous solutions at 3, 4, and 5% β-glucan with high molecular weight (HMW):low molecular weight (LMW) ratios of 0:100, 25:75, 50:50, 75:25, and 100:0 were evaluated.

Effect of anionic polysaccharide, sodium alginate, on the rheological characteristics of gelatin gels is studied. It follows from the rheological curves that low-temperature gelatin gels with

Hardness, at 40% compression, increased with concentration, and 25:75 and 50:50 gels were hardest at each concentration. Ordered microstructure, apparent in 0:100 gels, diminished with HMW β-glucan addition.
