The phrase "a shift of concentration" is correct and usable in written English.
It can be used when discussing changes in focus or attention, particularly in contexts like education, work, or mental processes.
Example: "After a long meeting, I felt a shift of concentration as my mind wandered to other tasks I needed to complete."
Alternatives: "a change in focus" or "a shift in attention."
Ranking sites by concentration and by change in concentration across the day showed a shift of high NO2 concentrations across the central city from morning to afternoon.
Moreover, the overexpression of MT1-MMP in MDCK cells resulted in a shift of the collagen concentration threshold for cyst formation from 1.8 mg/ml to 2.5 mg/ml.
Raising the cell concentration by increasing the cell number resulted in a shift of the nominal concentration-effect curves for the elimination of H2O2 toward higher concentrations (Fig. 4a, b).
Following development of severe CHF, both noradrenaline and phenylephrine could produce a greater maximum tension and a shift of the resultant concentration-effect curve to the left compared to the curves seen before the development of CHF.
Overexpression of N-myristoyltransferase in parasites leads to a shift of IC50 to higher concentration thus providing strong evidence that this enzyme is the target of these compounds.
The main effect of oxidation is a reduction of the composite conductivity for a given concentration and a shift of the percolation threshold to higher concentrations.
Addition of salt causes a shift of the boundary toward a lower concentration.
An increase of Cl− concentration generates a shift of the cd plateau towards lower cathodic cd values.
When comparing the binding of supernatants with either 6 μg/ml PD-L1-IgG or PD-L1-IgM fusion protein and J-chain, a shift of the binding curve toward lower concentrations of PD-1 was observed (Fig. 2B).
They reported that ε increase with increasing CNT concentration, resulting in a shift of reflectivity peak toward lower frequency [2].
