That's an entirely misleading statement, and unnecessarily flippant delivery too.

I would say that the _article_ , which surely was not written by "these scientists", is very light on the important and interesting details. Possibly not aimed at a "programmers" audience.

It literally says what materials they've used it with successfully and mentions what materials they're still aiming to be able to use.

The single sentence about "polymer-metal composites" and "metal" raises more questions than it answers. To me, anyway.

I'm sure that "these scientists" are on the case, but the article not so much.
