The phrase "assembly concentrations" is correct and usable in written English.
It can be used in contexts related to chemistry, biology, or manufacturing, where it refers to the concentration of components in an assembly or mixture.
Example: "The assembly concentrations of the reactants were carefully measured to ensure optimal reaction conditions."
Alternatives: "component concentrations" or "mixture concentrations".
From Figure 7a, the resistances of Hy-rGO-based sensors could be calculated to be 12.3, 14.5, and 89.3 KΩ, respectively, when the assembly concentrations of GO were 1, 0.5, and 0.25 mg/mL.
All of the sensors based on Hy-rGO and Py-rGO, which were fabricated with different assembly concentrations of GO solution, were tested toward 50 ppm NH3 balanced in synthetic air.
Similar situations occurred for Py-rGO devices, as shown in Figure 7b, the resistances of the devices were 13.5 and 28.2 KΩ respectively when the assembly concentrations of GO solution were 1 and 0.5 mg/mL.
When the assembly concentrations of GO solution was high (1 mg/mL), much more Py-rGO sheets were deposited on the surfaces of Au electrodes; as a result, it is hard for NH3 gas to penetrate into the rGO flakes and the complete interaction between NH3 and rGO sheets could not be ensured.
In order to determine the optimal condition for the fabrication of sensing devices based on assembled rGO, the response of different sensing devices fabricated under different assembly concentration of GO solution were studied, and the exposure time of 12 min was defined here as the effective response time[29].
The mechanism of cellular uptake was elucidated monitoring the dependence of intracellular red fluorescence from the assembly concentration, time and presence of specific uptake inhibitors.
However, when the assembly concentration of GO solution decreased to 0.25 mg/mL, the resistance of the resultant device increased greatly.
In addition, the resistances of the sensing devices based on Hy-rGO and Py-rGO increased with the assembly concentration of GO solution.
It means that formed in an optimized assembly concentration of AHA solution, molecular adsorption layer on the copper surface is compact for enhancing corrosion protection [32].
