2019-12-05 · NaOCl led to the greatest alteration of its rheological parameters. CONCLUSIONS: Irrigant solutions and intracanal medications adversely affected at least 1 of the tested rheological properties of both sealers, except for DW and 3% NaOCl, which did not alter any rheological property of GFB.
2020-11-01 · More CH is an indication of the greater degree of hydration at higher curing temperatures which leads to enhancement of the rheological properties of the mixture due to the two following processes: i) the produced hydration products (e.g., CH, C–S–H, ettringite) fill up the voids, and also increase the solid volume fraction in the CPB system and ii) the consumption of water in the cement hydration process results in the reduced thickness of the adsorbed water film that
Compression tests revealed that these semi-IPNs were robust materials with compressive modulus between 13.3 and 90.5kPa, the addition of Salecan increased the fracture strain from 71.1% to 88.8%. Rheological measurements play an essential role in quality control (QC) of many liquid and semi-solid materials. Two Point Tests It is well established that the flow properties of fresh concrete at low shear rates approximate the Bingham model, expressed as follows: 2020-11-01 · More CH is an indication of the greater degree of hydration at higher curing temperatures which leads to enhancement of the rheological properties of the mixture due to the two following processes: i) the produced hydration products (e.g., CH, C–S–H, ettringite) fill up the voids, and also increase the solid volume fraction in the CPB system and ii) the consumption of water in the cement hydration process results in the reduced thickness of the adsorbed water film that Saliva is a complex biological fluid that cannot be effectively studied by conventional methods such as theFerranti-Shirley Viscometer. Testing with theWeissenberg Rheogoniometer shows that saliva is viscoelastic and that the dynamic viscosity falls from 400-0.1 Poise over the frequency range 2.5×10−3 to 10 Hertz. The calculated elastic contribution can be correlated with dry weight content Salecan is a recently identified water-soluble viscous extracellular β-1,3- d -glucan polysaccharide from an Agrobacterium species. It is a high-molecular-mass polymer (about 2 × 10 6 Da) and composed of a linear chain of glucosyl residues linked through a repeat unit of seven β- (1,3) and two α- (1,3) glucosidic bonds.

have established relationships between the molecular structure of CMC and the rheological properties of the aqueous solutions over the CMC concentration range 0.5–3%. They reported that the molar mass and the polymer concentration are the governing parameters, whereas the degree of substitution (DS) has only a little influence affecting primarily the solubility.

Material and rheological properties of (glycidoxypropyl) trimethoxysilane modified colloidal silica coatings Korea-Australia Rheology Journal December 2004 Vol. 16, No. 4177 (TA Instruments AR2000) at 30oC. Prior to the rheological characterization, the suspensions were stirred for 20 min-utes, because nanoparticles had a higher tendency to rheological properties of fuel rich propellant slurry was st udied, and the results are .
3.5g of the flour sample was Chapter 1 Rheological Properties of Tomato Products.
The rheological properties of particles suspended in a non‐polar mineral oil have been investigated as a function of volume fraction of particles, particle size, surface properties and shear rate.
ZX09, has been the subject of considerable interest in recent years because of its multiple bioactivities and unusual rheological properties in solution. In this study, both succinyl and pyruvyl substituent groups on salecan were identified by an enzymatic hydrolysis following nuclear magnetic resonance Abstract.
The material properties that govern the specific way in which these deformation or flow behaviors occur are called rheological properties. The Greek philosopher and scholar, Heraclit (550–480 BC) once said “ πάντα p ɛĩ” (“everything flows”).
ZX09, mainly composed of β- (1→3)-D-glucosidic linkages as the main backbone structure, together with a small portion of α- (1→3)-D-glucosidic linkages [ 20 ].
Salecan is a novel soluble glucan produced by Agrobacterium sp. ZX09, displaying the ability to inhibit pancreatic amylase and reduce postprandial glucose.

With increasing frequency, the storage and loss moduli G′ and G″ of Salecan solution increased and complex viscosities decreased continuously, which showed an elastic behaviour. All data indicated that Salecan has excellent rheological properties and could be utilized in food industry as a new source of thickening agent. Salecan is a novel soluble glucan produced by Agrobacterium sp. ZX09, displaying the ability to inhibit pancreatic amylase and reduce postprandial glucose.
The research here provides an investigation of the rheological properties of Salecan solution over a wide range of shear rate (0.001-1000 s-1), frequency (0.1-100 rad/s), concentrations (0.3%, 0.5%, 1.0% and 1.5%), temperature (5-95°C) and
2018-08-01 · Salecan (CAS RN: 1439905-58-4) is an unbranched, macromolecular (1 → 3)-β-D-glucan with satisfactory rheological properties (Xiu et al., 2010; Xiu, Zhou, Zhu, Wang, & Zhang, 2011).

2013-03-20 · Salecan is an identified extracellular macromolecule from Agrobacterium sp.
2018-05-16 · Thus, rheological studies are important for studying the behavior of these visco-elastic fluids. In the present work, we systematically study these properties by investigating the effect of concentration, temperature and molecular weight of PEG as additives in a common base STF of 20% fumed silica in PEG200 under both steady and dynamic rheology.
The physical properties of these polymers make these glucans not suited for all applications as food additive.
