Duct Tape emits X-rays when unpeeled in vacuum

Great research, but I nearly choked on this sentence:
I can't wait for the Sticky Tape-Using Fast Fusion Universal Powerstation (STUFF-UP)

Its actually clear scotch or packing tape they used in the experiment, but duct tape probably works too.

I can't wait to show this to my wife, she's in radiology.

Three questions
WHAT???
is my first question. Then I chew on the actual statement and make my second question
IS THERE ANOTHER LINK TO THE ARTICLE?
I don't have a Nature account, you see. So I can have a chance at warping my mind around the third question, which is...
HOWCOME?
The sensation of being knocked over the head by the universe with an item I rely on frequently is too pleasurable, it's almost sinful. But I don't believe it yet and don't exactly buy that one about breaking chemical bonds. X ray energy I associate with ionization of molecules, not with the formation and breaking of covalent bonds in organic molecules. I don't know, but were that the case, a lot of chemical reactions in organic chemistry would produce X-rays.
Besides, I do suppose that the exposed adhesive has a higher potential energy than the adhesive sticking to something. Else it would not stick to itself and most substances (for example to itself) and it would not cost some effort to separate the tape from a surface.
Just off the top of my head, correct me if I shot a blooper.
But I hope it is true and not some sort of joke. These guys force me to waste my infinitely useful duct tape... and I will feel :ripped:

Thanks a million, gawinnard
So it is triboluminescence.
Well, still I don't understand how come because I am no expert in tribology. But there's a mechanism which is known to furnish visible, UV, and (now we know!) X-ray energy photons readily.
Neither the researchers understand it fully. Collective blast? Cooperative phenomena?
Impressive though... Nanosecond pulse(s) of hundreds of thousands of X-Ray photons, which is fine for reliable imaging and many other applications. From peeling tape! Now what? A handheld or tabletop tomograph machine with a small, safe "peeling" or "rubbing" source? The huge CAT machines will be replaced by duct tape?

Now .. inertial confinement fusion using radiation implosion using focused X-rays from duct tape!! Free energy!! Oh yeaa!!

Why free? Someone still has to pull the tape's end. :lol:

It's fun but it's not a joke...
A safe, portable, economic (in terms of manufacturing and of energy use), X-Ray source producing short pulses of a reasonable intensity is just what the doctor (in physics) ordered for all forms of X-ray imaging. Including X-ray tomography.
It matters also if they can produce anything resembling a beam with a triboluminescent source. I haven't the empirical knowledge to do a reasonable average of losses (attenuation and scattering) through a typical human torso (we don't know the frequencies), or of the sensitivity of the detectors used in CT tomography.
So it's wild speculation that they can make a tomograph machine out of this, and again we can defer to Dr. Schweiger in his professional area of expertise.
