"insufficient efficiency" is correct and usable in written English.
You can use this phrase when discussing the relative effectiveness of various methods or processes. For example, "The project was unsuccessful due to the team's insufficient efficiency in completing their tasks."
Though the OSCs are comparatively efficient for commercial application due the insufficient efficiency and lower environmental stability factors controls the early arrival to the market.
However, significant formation of cis-DCE within the PRB resulted in an overall insufficient efficiency for cis-DCE removal.
The traditional generators are generally difficult to manage rapid power fluctuations due to their insufficient efficiency requirements and low responding speed.
These manipulations generally require large amounts of DNA at the beginning and tend to have insufficient efficiency for library cloning.
However, the reported severe or life-threatening complications that are associated with the use of exogenous stem cells/progenitors, including immunorejection, the risk of tumorigenicity and the insufficient efficiency of these progenitors/stem cells to acquire cardiac lineages to reconstitute the lost cardiac tissues, has hindered the clinical translation of this technology [ 21– 23].
The first reason was the insufficient filtration efficiency of the OA system for PM2.5 due to filter bypass and design shortage.
In lab setups incorporating SAW-based microfluidic actuators, insufficient energy efficiency resulting e.g. from interdigital transducers (IDTs) with inadequate electrical impedance, absorption of SAW power in vessel walls or maladjusted wavelengths, is often simply counteracted by an increase of the output power of the signal source.
Whereas this protocol still suffers from the drawback of insufficient transfection efficiency [18, 19].
Preliminary test radiolabelling proved useful in cases where insufficient radiolabelling efficiency was solved by longer incubation.
Because of the poor amplification of LRP1B, the gene was excluded from further analysis (insufficient qPCR efficiency).
