Nitrogen gas is an industrial gas produced by the fractional distillation of liquid air, or by mechanical means using gaseous air (pressurised reverse osmosis membrane or pressure swing adsorption). Nitrogen gas generators using membranes or pressure swing adsorption (PSA) are typically more cost and energy efficient than bulk-delivered ...
Does nitrogen admit metastable allotropes under standard conditions? [10] Can new solvents or other techniques make direct carbon capture economical? [11] Can artificial photosynthesis make any common fuels? [12] What is a reliable synthesis and stabilization method for catenary allotropes of sulfur and carbon?
The stated intent was to recruit "intelligent individuals" by presenting a series of puzzles to be solved; no new puzzles were published on January 4, 2015. A new clue was posted on Twitter on January 5, 2016. [5] [6] Cicada 3301 posted their last verified OpenPGP-signed message in April 2017, denying the validity of any unsigned puzzle. [7]

Solid nitrogen is mainly the subject of academic research, but low-temperature, low-pressure solid nitrogen is a substantial component of bodies in the outer Solar System and high-temperature, high-pressure solid nitrogen is a powerful explosive, with higher energy density than any other non-nuclear material.
By: Patrick Jones. A 30-year-long question about black holes has finally been resolved. Apparently, black holes twist space time like taffy. This finding is based off a principle put forward by ...
Reddit user marijn1412 cracked the code behind the song declared the "most mysterious song on the internet" after a nearly two-decade-long search.
Example 3 — nitrogen oxides: Dalton was aware of three oxides of nitrogen: "nitrous oxide", "nitrous gas", and "nitric acid". [16] These compounds are known today as nitrous oxide, nitric oxide, and nitrogen dioxide respectively. "Nitrous oxide" is 63.3% nitrogen and 36.7% oxygen, which means it has 80 g of oxygen for every 140 g of nitrogen.
