Development of a solid material capable of slowly releasing hydrogen sulfide and nitric oxide
(PHYSorg.com Chemistry)

National Institute for Materials Science has developed a solid material capable of slowly releasing hydrogen sulfide (H2S) and nitric oxide (NO) when exposed to air. These gases can induce physiologically favorable effects at low concentrations (e.g., reducing inflammation and expanding blood vessels). However, their medical use has been limited due to difficulties in storing them and regulating their concentration. This material can release these gases safely and conveniently and will facilitate their medical use.
