Here, we present evidence from laboratory experiments for the formation of nitrogen-containing complex organic ions by sequential reactions of acetylene with the pyridinium and pyrimidinium ions in ...

Nitrogen hypoxia is the term for when enough nitrogen gas is inhaled that it deprives the body of oxygen -- in this instance, intentionally so, as a means of execution. The protocol in Alabama ...

This is because when people breathe in nitrogen without expelling it, the gas replaces oxygen in the body and those levels plummet. If oxygen levels fall below 10 percent, it can be fatal.

Alabama’s second nitrogen gas execution is set to go ahead as planned after a death row inmate agreed to drop further litigation against the state as part of a settlement agreement. A federal ...
