The phrase "amounts of material available" is correct and usable in written English.
It can be used when discussing the quantity of resources or materials that are accessible for a particular purpose or project.
Example: "The amounts of material available for the construction project will determine the timeline and budget."
Alternatives: "quantities of material accessible" or "volumes of material on hand".
However, the project was much more difficult than anticipated as the amounts of material available were miniscule and the lab facilities unable to scale up to the level required.
Restrictions imposed by obscure sources and small amounts of material available for testing were initially impediments to their study.
Useful information to provide possible investigators with includes limitations of the informed consent, types and amounts of material available and storage conditions.
Because of the very limited amounts of material available and the large volume needed for measurements using the H2O2 electrode system, it was not feasible to use the electrode system for measurements in broken cell or purified preparations.
Second, the amount of material available for downloading is enormous.
It's also disturbing when you consider the amount of material available.
Do this by unpicking the side seams in the folded over hem allowance to increase the amount of material available in the circumference.
In many cases it is crucial to pick a minimal set of the most informative markers due to the limited amount of material available for analysis.
For example, their photovoltaic cell converts incoming photons (packets of solar energy) into flowing electrons with notable efficiency, given the small amount of material available for absorbing incoming sunlight.
The bronze coin, about 19 mm. in diameter, of the Yaudheya series, has been dated about 100 B.C. From the very large amount of material available, Prof. Sahni has been able to work out in the greatest detail the entire story of the casting technique employed1.
Due to the limited amount of material available and the unique geometry of the disks, test specimen design and development of fixturing for machining operations were critical aspects of this work; multiple designs were considered and refined during mock-up testing on unirradiated disks.
