thixotropy

 [thik-sot´rah-pe]
the property of certain gels of becoming fluid when shaken or otherwise agitated and then becoming semisolid again at rest.

thix·ot·ro·py

(thik-sot'rŏ-pē),
1. The property of certain gels of becoming less viscous when shaken or subjected to shearing forces and returning to the original viscosity on standing (for example, synovial fluid, ferrous hydroxide gel).
2. A characteristic of a system exhibiting a decrease in viscosity with an increase in the rate of shear, usually a function of time.

There is however also the effect of starch thixotropy which appears most clearly at the lower level of monomer addition (Fig.
Considering the abovementioned, the current study revealed such features as maximal tension of shear, effective viscosity and thixotropy depending on temperature (Ahmetova and Egorova, 2008; Chawla and Saraf, 2012).
Note that dispersing nonfunctional-ized fumed silica in water at high concentrations would originate significant thixotropy and even gelation, due to extensive inter-particular hydrogen bonding.
It was verified the influence of thickeners on the viscosity as a function of time and shear rate, and adjusted the models of Bingham, Casson, Herschel-Bulkley and Ostwald-de-Waele to the flow curves and the Weltman's model to thixotropy test.

To Strik, then, thixotropy is also a metaphor for the perceptual power of the viewer who, through the act of looking, sets in motion the transformation of a hardened image to a more malleable one.
These solutions obey power-law model and do not suffer from thixotropy or change on aging.
Thixotropy can be defined as an isothermal and comparatively slow recovery of consistency through shearing on standing of material.

Thixotropy indicates continuous breakdown or rearrangement of structure with shearing time (Rha, 1978 apud Bhattacharya, 1999).
The casting slip was not suitably robust and the thixotropy hard to perfect.
It also introduces the development and implementation of a sample preparation method to reduce the impact of the thixotropy of a solder paste in conjunction with enhanced plate/plate rheometry.
