The phrase "a number of liquid" is not correct in written English.
It is typically used when referring to multiple items or quantities, but "liquid" is an uncountable noun and should not be used in this context.
Example: "A number of liquids were tested for their viscosity in the experiment."
Alternatives: "several types of liquid" or "various liquids".
Many manufacturers still use the controversial chemical, but a number of liquid brands advertise the fact that their flavours contain no diacetyl, with some smaller companies favoured by more experienced vapers even paying for independent chemical analyses of their liquids and sharing the results with consumers.
The work of Heric and Brewer (1969 Journal of Chemical Engineering Data, 14, 55 63) which involved testing a number of liquid viscosity correlations resulted in concluding that the McAllister (1960 A.I.Ch.E. Journal, 6, 427 431) model was the most accurate.
We now describe quantitatively how the thermal and mechanical properties of a number of liquid crystalline epoxy resins vary with polymer mesogen concentration, using biphenyl- and biphenol-based diepoxides with varying spacer lengths and a range of aromatic diamine curing agents.
A number of liquid sodium devices have been implemented with a spherical geometry.
In logical succession, it also contains the synthesis of a number of liquid biofuels and hydrogen from bio-based syngas.
There are a number of liquid processes and waste streams at nuclear facilities (i.e., nuclear power plants, fuel reprocessing plants, nuclear research centers, etc).
Lewis acid catalysts have found widespread applicability for a number of liquid-phase oxidation and isomerization reactions.
For those individuals who may have difficulty swallowing tablets, colesevelam (WelChol®) is also available alternatively as a powder which can be mixed with a number of liquids to form a suspension that can be ingested.
A number of hydrodynamical liquid crystal examples are computed to demonstrate the effects of the parameters and the performance of the method.
In this work, a number of ionic liquid + catalyst combinations are screened using a combinatorial experimental technique with fructose, high fructose corn syrup, and glucose as a feed.
Materials of interest typically have a Tg below ambient, a crystalline melt transition around 100°C, and exhibit a number of complex liquid crystalline phases with clearing ranges to isotropic in the region 120 180°C.
