I totally buy it that there is no such thing as an "unidentifiable alloy." I also buy it that journalists, not being materials scientists or indeed scientists of any sort, do not know the difference between an "alloy" and "a hunk of some hard material," so at some point they wrote down "alloy" because the word sounds exotic, like something you'd find at Area 51. This happens in the press /all the time/. Journos get s…
Yeah, if you are willing to buy that they have something stored they can't identify, this is the most logical explanation. That said, I would still buy that there are probably almost no materials that we couldn't at least get a handle on. If they were truly incomprehensible it would likely be because they were the result of manipulating properties that we don't even know exist yet (higher dimensionality, etc, whateve…
I agree the reporters probably flubbed the word "alloy" for lack of a better understanding of science or a better term to describe it.
An integrated circuit is a fine grained combination of several different kinds of metal and other materials, but they're meticulously arranged and sandwiched together, not just melted together into an alloy.
At what point do you draw the line between nanotechnology and alloy, when you have the technology to 3d-print each and every atom?
