A key statement in this paper is the very first sentence: "Nanoparticles show many novel properties different from their bulk materials."
This is why some here take issue with Ed's relying only on ". the laws from the past 100 years of chemistry/physics". Those laws were developed with bulk samples, not nanoparticles, so they may or may not apply to what's happening in LENR, and my $ is on the novel properties which the referenced paper is studying. This may also be the reason why the 'gray-hairs', or grairs to borrow a theme from Star Trek, have not been able to figure this out; they can't think out of the bulk-matter-box. So keep up the informed and researched speculations, cuz that's what we Vorts are good at!

Unfortunately, most of the search results for amorphous Pd out there return various Pd-based alloys -- not pure Pd.

The metal is vaporized in a vacuum chamber and then supercooled with an inert gas stream. The supercooled metal vapor condenses into nanometer-size particles, which can be entrained in the inert gas stream and deposited on a substrate or studied in situ.

Yes, I imagine abrasion would cause lots of surface cracks on an amorphous metal - if it behaves like glass. I had wondered in the past whether the surface preparation of the palladium electrodes was one of the keys. Don't know how to develop cracks in a powdered material. I suppose that if the material is not too ductile, just the formation of the powder in a ball mill would do it. SO experimenting with the ball mill might be one possibility.
