Hydrogen Sulfide (H2S) Gas Sensor: A Review

IEEE Sensors Journal, 2019
This paper reviews the most important sensor-based methods that are commonly utilized for detecting and measuring hydrogen sulfide (H2S) gas. It identifies a quite comprehensive overview related to the toxicity and hazardous effects of H2S gas from an ...

Hydrogen Sulfide Inhalation Injury

Journal of Burn Care & Rehabilitation, 2000
Hydrogen sulfide is a colorless, noxious gas with the distinctive smell of rotten eggs. This compound is a powerful reducing agent that is encountered in a number of industrial processes. When hydrogen sulfide is present, it exposes workers to the potentially lethal effects of the rapid hypoxemia that results from exposure to this agent.

Conductive Hydrogen Sulfide-Releasing Hydrogel Encapsulating ADSCs for Myocardial Infarction Treatment.

ACS Applied Materials and Interfaces, 2019
Hydrogen sulfide (H2S) exhibits extensive protective actions in cardiovascular systems, such as anti-inflammatory and stimulating angiogenesis, but its therapeutic potential is severely discounted by the short half-life and the poorly controlled ...

Hydrogen sulfide as a source of hydrogen

International Journal of Hydrogen Energy, 1984
Abstract We suggest that hydrogen sulfide (that which is removed from fossil fuels as an unwanted waste product, as well as that which might be sought as a mineral in its own right), should be considered as a source of hydrogen. We discuss several techniques by means of which hydrogen sulfide might be thus exploited.

Hydrogen sulfide intoxication

2015
Hydrogen sulfide (H2S) is a hazard primarily in the oil and gas industry, agriculture, sewage and animal waste handling, construction (asphalt operations and disturbing marshy terrain), and other settings where organic material decomposes under reducing conditions, and in geothermal operations.

Hydrogen Sulfide as a Neuromodulator

Molecular Neurobiology, 2002
Hydrogen sulfide (H2S) is a well-known toxic gas with the smell of rotten eggs. Since the first description of the toxicity of H2S in 1713, most studies about H2S have been devoted to its toxic effects. Recently, H2S has been proposed as a physiologically active messenger.

Chemisorption of hydrogen sulfide on lead sulfide

Russian Journal of Electrochemistry, 2006
The hydrogen sulfide chemisorption on lead sulfide at 22–100°C is studied by static testing in a vacuum and by pulsed chromatography. It is established that H2S is sorbed in reversible and irreversible forms and that the process is accompanied by the sample charging.

Recovery of hydrogen from hydrogen sulfide with metals or metal sulfides

International Journal of Hydrogen Energy, 1982
Abstract The following two types of reactions were investigated for the recovery of hydrogen from hydrogen sulfide: Type 1 H 2 S → H 2 + S 0 , Type 2 H 2 S + O 2 → H 2 + SO 2 Each type of reaction is constructed by a two-step cycle, in which H 2 S is reacted with metal or metal sulfide and then the resulting sulfide undergoes thermal ...

Hydrogen Sulfide and Urogenital Tract

2015
In this chapter the role played by H2S in the physiopathology of urogenital tract revising animal and human data available in the current relevant literature is discussed. H2S pathway has been demonstrated to be involved in the mechanism underlying penile erection in human and experimental animal. Both cystathionine-β synthase (CBS) and cystathionine-γ

Physiological implications of hydrogen sulfide: a whiff exploration that blossomed.

Physiological Reviews, 2012
The important life-supporting role of hydrogen sulfide (H(2)S) has evolved from bacteria to plants, invertebrates, vertebrates, and finally to mammals.
