chitosan is a polysaccharide derived from chitin by n-deacetilation, which has the property of gel formation. the objective was to develop a chocolate milk beverage using modified (hydrogel) chitosan as a thickening agent, and to make a sensory and rheological evaluation of this beverage. in the sensory evaluation an acceptability and comparative test with 50 local consumers was carried out, wi...

Nano-TiO2 (NT) and nano-SiO2 (NS) were separately added in the cement paste to investigate the rheological property of fresh mixtures and mechanical strength in hardened state. The effects of different dosages and types of nano-particles on the properties of cement paste were studied. The results indicated that the rheological behavior of the fresh cement paste coincides with the Modified Bingh...

Effective and accurate methods for characterizing rheological changes of proteins by alteration of their level, composition, or conformation are of significant clinical and biotechnological utility. Current implementations to measure rheological properties of a fluid, however, require mechanically moving components or off-chip measurement setups, thereby preventing incorporation of them into mi...

This paper presents the design, fabrication and evaluation of magneto-rheological damper. Semi-active control devices have received significant attention in recent years because they offer the adaptability of active control devices without requiring the associated large power sources. Magneto-Rheological (MR) dampers are semiactive control devices that use MR fluids to produce controllable damp...

© Appl. Rheol. 15 (2005) 90-97 Abstract: There is often a need to perform rheological tests on dilute polymeric liquids at a time long after their initial preparation, for example if a more sensitive or novel method of measuring a material property (such as uniaxial/biaxial extensional viscosity or second normal-stress differences) becomes available. An inexpensive method of storing such fluids...

Background: Tailings dams are made up of mining residue deposits, and they represent a high risk, in terms of mechanical instability. In the event of collapse, the tailings in such dams may be released and flow over long distances, with the potential risk of extensive damage to property and life. The traditional geotechnical assessment of tailings facilities has mainly concentrated on the stabi...

In this paper, the formation of liquid crystal structure in preparation of emulsion and the change of those liquid crystal structures during storage and usage were studied. Besides, the rheological and moisturizing property of the liquid crystal structure emulsion was investigated as well. The results show that the liquid crystal structure at oil-water interface in the emulsion forms gradually ...
