For all the automation effort, there's always something that has to be done by hand...

From the experimental paper: "The XRD sample holders must be cleaned manually when the lab has depleted its stock"

A couple other observations on the experimental side:

They define success as being a sample with >50% of the target material. I guess that's success, but wow you can't test any actual properties (hardness, electrical conductivity, etc.) with samples like that.

As the reviewers noted, they're only making oxides (no alloys or intermetallics).

Likely that issue could be "solved" by using disposable plastic tubes or plates if you really wanted.
