I suspect the reason this may be trending again is the 'Black Nitrogen' was just discovered. So called because of its similarities to 'Black Phosphorous', it is the only known allotrope of Nitrogen other than Ninitrogen,and the only one that has properties similar to elements on the periodic table row underneath Nitrogen. It show good conductivity too, but researchers are unable to stabilize it so commercial uses are out until they do. https://phys.org/news/2020-06-black-nitrogen-high-pressure-material-puzzle.html https://phys.org/news/2020-06-black-nitrogen-high-pressure-m...
