Previous studies have indicated a binary change of this capacitive effect for different ranges of ionic strengths; in particular, this capacitive effect was positively correlated with pore fluid ionic strength at low ionic strength, but negatively correlated at high ionic strengths [24].
Hydrogels are classified as stimuli-sensitive swelling-controlled release systems because they can respond to various environmental conditions, such as pH, the surrounding fluid ionic strength, temperature, an applied electrical or magnetic field, or glucose level changes.
Effect of physical properties of the fluid (surface tension, ionic strength, liquid viscosity) and that of the non-Newtonian behavior on mixing time was studied.
The way shale interacts with the injected fluid depends on shale properties, such as mineralogy, rock mechanical properties, porosity, clay composition and permeability, as well as the properties of injected fluids such as ionic strength and salt concentration (Gomez and He 2012; Lal 1990; Horsrud et al. 1998).
The biggest disadvantage of FET sensors is that they may not work with blood samples or body fluids, because the ionic strength of such physiological solutions is about 150 mM, which yields a Debye screening length of about 1 nm.
The correlation between ionic strength (fluid conductivity) and σ" is positive during the early stage of Phase III, indicating a promoted polarization magnitude in this phase.
Thus, the decrease of ionic strength (fluid conductivity) observed during the early stage of Phase I would have been predicted by Lesmes and Frye [24] to have resulted in a decrease of σ", contradictory to our observations.
Silica is used to exhibit various functions in the DF: it is added to a drilling fluid to change density, ionic strength, charges, etc. that are needed for special functions of DF such as drill-bit cooling, bit cleaning, effective cuttings removal to surface, downhole pressure control, and shale stabilization.
Although relatively smaller NBs were released after switching the eluting fluid to one with lower ionic strength, most of the NBs in lower-pH water were still retained in the porous media even altering the chemical condition.
The thickness of the EDL is strongly dependent on the ionic strength of the fluid medium and has a significant effect on electrical conductivity.
Human blood serum was used because of its similarity to natural tear fluid in terms of pH, osmolarity, ionic strength, and protein composition [ 54- 57].
