I don't know your background, so it is hard to know what to recommend. If you have a PhD in a subject area then in theory you should have enough general knowledge to be able to effectively read a recent review article explaining the state of the art in some sub-discipline. I can then use the references in that paper to read about the concepts and ideas I am not familiar with and I think are important to understand. Using google scholar (not regular google), I found this recent article "Contributed Review: Culet diameter and the achievable pressure of a diamond anvil cell: Implications for the upper pressure limit of a diamond anvil cell" https://doi.org/10.1063/1.5049720 https://doi.org/10.1063/1.5049720 I would read this to update my ideas about what diamond anvil cells can do right now. Then, if I wanted to actually use one or find out if I should use one, I would talk with one of the authors of a paper referenced in the review paper that I thought was good and dealt with the particular reason I wanted to use one. That was a bit long winded. Hope it helped.
