At the most trivial level, look at wikipedia’s article on diamond, the phase change diagram in particular. Diamond starts to be thermodynamically preferred over graphite at around 100k atmospheres, and has been known about for a century.
For a 2012 paper, there’s this. Note that the first thing in the paper is the unquestioned statement “High pressure can fundamentally alter the bonding patterns of light elements and their compounds, leading to the unexpected formation of materials with unusual chemical and physical properties.”
Here’s a 2006 paper from Germany that directly looks at how high pressures affect the chemistry of alkalai metals, including sodium.
And a 1998 reference book containing five hundred pages of high pressure chemistry notes, including a handful of sodium compounds.
Seriously, nothing new here. Vastly overblown and irresponsible hype.
Thanks. I’m wondering now if there are no (more? diamonds are good for something) useful compounds to made under high pressure, or if it’s just a matter more time being needed for research.
There’s plenty of neat new stuff to be discovered in high pressure regimes, and I’m sure there will be reseach on it for quite some time.
I wasn’t objecting to the paper itself, I object to the vastly overblown hype. The research itself is probably valid if relatively uninteresting, but it certainly does not live up to the claims given.
