This study focuses on the spatial distribution of carbonation levels across the thickness of concrete sidewalk samples that are many decades old.
Always in real samples, there are many ions and determination of one of them may be influenced by others.
This is just a sampling; there are many more.
In Fig. 2b, Sample-B are many spherical particles which are uniform in size and dispersed on the surface of SWCNTs.
Each genomic fragment is sequenced from a single species, but within a sample there are many different species, and for most of them, a full genome is absent.
How many free samples are too many to take?
Clearly, this is a small sample and there are many areas of chemistry where we have not yet published anything.
This is just a sampling and there are many others but it's worth noting that many sharing their stories on these sites are still conservative Christians and even home schoolers.
In addition, there are many samples that were collected before leukocyte depletion became a standard technique.
There are many samples available that detail the structure and important information.
