The phrase "affecting the activity and" is correct and usable in written English.
It can be used when discussing the impact or influence on a particular activity or process.
Example: "The new regulations are affecting the activity and efficiency of the production line."
Alternatives: "influencing the operation and" or "impacting the process and".
The organic group appears to act as a modifier (horizontal spacer) around the active sites, thus affecting the activity and kinetics of the catalyst.
Salinity is an important factor affecting the activity and community structure of nitrogen transformation-related microorganisms in natural and engineered ecosystems.
In this critical review, we systematically shed light on the key factors affecting the activity and stability of enzymes in ILs and discussed the relationships among these factors.
The effect of the preparation procedure and La2O3/Pd weight ratio on activity of the resulting catalysts can be explained by: (i) the amount of Pd particles in contact with La2O3 moieties, positively affecting the activity, and (ii) the extent of coverage of Pd particles by La2O3 patches, negatively affecting the activity.
The duration of the antibiotic treatment was found to be an important factor affecting the activity and stability of the GIT carbohydrate metabolism.
Hepatocyte growth factor/scatter factor may induce invasive growth by affecting the activity and expression of cadherins, integrins and matrix metalloproteinases.
The strength of hurricane seasons affected the activity, and the especially active 1835 season brought even bigger profits.
Results showed that water exposure did not affect the activity and persistence of the tested combination.
Yan et al. (2013) found that the catalyst preparation methodologies significantly affected the activity and stability of Ni/SiO2 catalysts.
This indicates small changes in the specific surface area as the result of impregnation sequence will not fundamentally affect the activity and selectivity of the catalysts.
To conclude, the choice of the type of zeolite/silicoaluminophosphates affects the activity and selectivity of the different steps in the SCR process.
