“Stratospheric clouds of nitric acid trihydride ice particles form in this cold polar vortex.”
“All who have learned a little of chemistry doubtless remember the experiment with vortex rings produced by phosphorus trihydride mixed with a little phosphide of hydrogen.”
“Lanthanum trihydride stabilized at about 100,000 atmospheres and a transition temperature of - 423°F (20 Kelvin), while the other two stabilized at about 200,000 atmospheres and temperatures of -427 °F (18 K) and -387 °F (40 K) for ScH”
“The compounds were scandium trihydride (ScH3), yttrium trihydride (YH3) and lanthanum trihydride (LaH3).”
“In yttrium trihydride, the superconductivity state reappeared at about 500,000 atmospheres, but not in the others.”
Looking for tweets for trihydride.
