The phrase "a maximum in efficiency" is correct and usable in written English.
It can be used when discussing the highest level of effectiveness or productivity in a particular context, such as business or engineering.
Example: "The new software update has resulted in a maximum in efficiency, allowing the team to complete tasks in half the time."
Alternatives: "peak efficiency" or "optimal efficiency".
A maximum in the removal efficiency is observed at a certain seeding concentration and at the lower pH values, which is explained from competing effects that take place with respect to magnetic susceptibility and size of aggregates as the seeding concentration and solution pH are increased.
The bilinear approximation of a biconvex FPR accurately predicts the position of the maximum in efficiency, even for large convexity, but somewhat overestimates its height and width.
This maximum is explained by the combination of an increase of short-circuit current density Jsc and a decrease of open-circuit voltage Uoc with L. In configuration B, Jsc also increases with L, but Uoc stays rather constant and the maximum in efficiency only appears at very large values of L ≈ 12 mm.
Consequently, the DMUs identified as 'high performers' are only the firms which have a maximum efficiency in the relevant set of migrant entrepreneurs.
T7E1 showed a maximum efficiency in a DNA pool containing between 5 and 30% of 20-bp deletion mutant DNA, and by symmetry from 70 to 95% of mutant DNA.
From Fig. 4, we observe that there is a maximum energy efficiency in each case of, where κ is the set of occupied sub-bands.
The effective particle size of OPA was determined to be 212 300 μm, resulting in a maximum bleaching efficiency of 97.3%.
The lessons learnt through the characterization measurements were subsequently utilized to produce an optimized cell morphology, resulting in a maximum conversion efficiency of 16%.
With proper device design high short-circuit current densities of 29.6 mandm2 and quantum efficiencies up to 90% are obtained resulting in a maximum conversion efficiency of 9.6% within a 2-μm-thick μc-Si H solar cell.
The selective formation of HCOOH on the prepared Sn electrocatalyst was observed with high faradaic efficiency and HCOOH formation rate over the rod shaped Sn catalysts, resulted in a maximum faradaic efficiency of 94.5% at 1.6 V vs Ag/AgCl and a maximum formation rate of about 0.5 mol/gcat h at 2 V vs Ag/AgCl.
