Just when you thought that spintronics and quasi-crystalline transistor fields were the new states of matter, along comes another new state of matter - Transparent Aluminum.
But the transparent aluminum, which is made by blasting regular "foils" with soft X-rays, doesn't stick around very long. In fact it only lasts about 40 Femtoseconds, or a little less.
So much for "foils" in this universe. Physics has proven it.
