Chemists at Merck & Co. were performing experiments using nitric oxide at high pressure (10–20 bar) when two instances of an explosion occurred during rapid depressurization of the NO headspace from a ...

Nitric oxide is a double-edged sword. It’s a key signaling molecule that controls blood pressure and nerve impulses, yet when concentrations of the simple gas molecule are too high, it’s toxic to ...

Researchers are shifting focus from large arteries to microvessels, where nitric oxide activity may signal early circulatory changes before symptoms appear. Nitric oxide is a signaling molecule ...

Because metal-organic frameworks (MOFs) — highly porous metal complexes — are so structurally and chemically diverse, they could be used for many applications, such as drug delivery and environmental ...

Nitric oxide (NO) is a colorless gas and stable free radical that turns blue when it is liquefied or solidified. It was discovered and studied in 1772 by J. Priestley, who called it “nitrous air”. A ...
