The phrase "a decrease in the resistivity" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly when discussing materials and their electrical properties.
Example: "The experiment showed a decrease in the resistivity of the material as the temperature increased."
Alternatives: "a reduction in resistivity" or "a drop in resistivity".
At a composition of 75PA/25PE, presence of CNT at the interface promoted by premixing the CNTs in the PE phase, resulted in finer phase morphology and a decrease in the resistivity of up to five decades relative to other mixing procedures used.
Therefore, a decrease in the resistivity, while maintaining a constant current density, results in a decrease in the applied voltage gradient, and thus a decrease in the fluid flow due to applied electrical field.
Equations 23 and 26 indicate that an increase in the porosity of the reservoir results in a decrease in the total resistivity.
The original, conductive graphite-like structure was restored by reduction with N2H4 and annealing at 400 °C which, by gradual ordering of the carbon crystallites, caused a significant decrease in the resistivity.
The resistivity decreased with an increase in the film thickness or a decrease in the transparency.
After the incorporation of MWCNTs, a decrease in electrical resistivity of the fibers was found for MWCNT concentrations as low as 2 wt%.
The resistivity of the substituted indium (8.37 μΩ cm) is less than the replaced iron (9.61 μΩ cm) [20]; thus, a decrease in resistivity of the whole series is expected.
A decrease in apparent resistivity and an increase in the phase are shown after the removal of the resistors for different periods, of > 1 s for R1 and of > 100 s for R6.
The geoelectrical cross section (a) shows gradual decrease in the resistivity values toward the east in both the shallow and main aquifers.
By plotting the surface resistivity with respect to the loading content of SWNT in SWNT-PIL gel composites, a decrease in surface resistivity of gel composite (from 3.8 × 10 to 1.7 × 10 Ω/square) with an increase in the SWNT contents (from 0 to 1.5 wt.%) was recorded [ 129].
This decrease in the resistivity is due to an improvement in the crystalline quality of the layer.
