Absorption of hydrogen sulfide in aqueous solutions of iodine—a critical reviewPOROUS MEDIASOLID GAS REACTIONHEAT TRANSFERTurbidimetry is used to characterize the kinetics of agglomeration of a finely ground sample of potassium sulphate in different stirred media, i.e. water and several organic liquids...
The functionalized sensor demonstrates an improved sensitivity of over 120 % at 0.01 ppm when compared to the pristine sensor. Abstract Hydrogen sulfide (H2S), a toxic and corrosive gas, poses significant risks in various industries and environments. This paper presents an electrochemical sensor design...
Hydrogen sulfide (H2S) was initially recognized as a toxic gas and its biological functions in mammalian cells have been gradually discovered during the past decades. In the latest decade, numerous studies have revealed that H2S has versatile functions in plants as well. In this review, we summar...
In this paper, a method to extend the detection range of hydrogen sulfide (H2S) gas sensor is demonstrated. The sensor is based on AlGaN/GaN high electron mobility transistors (HEMTs) with Pt gate. It is observed that the as-fabricated devices exhibited sensing signal saturation at 30 ppm ...
Liang Chen1, Wei Shen3, Xiang-Fang Tang1, Ling-Jiang Min3, Qing-Shi Meng1, Shu-Kun Wang1, Bao Yi1 & Hong-Fu Zhang1 A number of emerging studies suggest that air pollutants such as hydrogen sulfide (H2S) and ammonia (NH3) may cause a decline in spermatozoa motilit...
remainder in the form of the dissolved uncharged H2S gas (~20−25%) and negligible amounts of S2− 8. Here, unless specified, we refer to the sulfide pool (H2S + HS− + S2−) as H2S. H2S modulates various physiological functions including inflammation, metabolism, ...
Correspondence: Colin Selman (Colin.Selman@glasgow.ac.uk) Hydrogen sulfide (H2S) modulates many biological processes, including ageing. Initially considered a hazardous toxic gas, it is now recognised that H2S is produced endogen- ously across taxa and is a key mediator of processes that ...

This review explored the advancements in metal sulfide-based photocatalysts, focusing on their synthesis, structural classification, and bandgap engineering for enhanced hydrogen production. Key characterization techniques, including XRD, SEM, TEM, UV-DRS, XPS, and others were discussed for understanding ...
Caution should be taken since an unbuffered stock solution from H2S gas tends to be acidic, whereas that from metallic sulfide is basic (Eq. (1)). In the following discussion, unless specified we use H2S to indicate all three species H2S, HS− and S2−. The bond dissociation energy ...
