Advanced Science, EarlyView.ABSTRACT Hydrogen sulfide (H2S) can be transformed into hydrogen (H2) through several chemical and catalytic processes, offering a promising route for both waste treatment and clean H2 production. This colorless, flammable, and toxic gas is found abundantly in swamps, volcanoes, hot springs, sewages, other natural gas fields, and even in refineries and

Polarography of sulfur compounds
1987Publisher Summary This chapter discusses the polarography of sulfur compounds. Many sulfur compounds, both inorganic and organic, exhibit electrochemical behavior that is useful for analytical purposes. Simple polarography with a dropping mercury electrode can provide a versatile method for the simultaneous identification and quantitative ...

Atmospheric sulfur compounds and microbes
Environmental Research, 1978Abstract The current increased emissions of sulfur dioxide have necessitated the determination of the background levels of atmospheric sulfur-containing compounds, both inorganic and organic, to understand better the natural cycling of S through the biosphere and the impact of added S pollution.

Attraction of rats to sulfur compounds
Behavioral Biology, 1978Adult male and female Sprague—Dawley rats were assayed for olfactory preference of various sulfur-containing compounds. Both sexes preferred dimethyl disulfide. Male rats were also interested in dimethyl sulfite and hexyl mercaptan odor, while females preferred methyl isothiocyanate.

Toxicology of Thiono-Sulfur Compounds
Annual Review of Pharmacology and Toxicology, 1982Thiono-sulfur-containing compounds cause a wide variety of toxic effects in mammals. These toxic effects of thiono-sulfur-containing compounds appear to be at least partially the result of their metabolism to reactive intermediates by the cytochrome P-450-containing monooxygenase enzyme systems.

Sulfur Containing Compounds as Antioxidants
1990Several sulfur containing antioxidants have been used for therapeutic use as hepatoprotectors and radioprotectors. In particular the dithiolthione SULFARLEM, used as anticholestatic drug for more than 40 years, is shown to be antioxidant; preliminary pharmacokinetic data in man are presented, and hepatoprotective and radioprotective effect in mice are ...

Secondary chemicals, especially alkaloids and terpenes isolated from plants, have interested chemists for many decades, yet only comparatively recently have their important roles in ecology been realized. They are no longer incorrectly considered to be just metabolic by-products.1 Investigations of secondary compounds produced by mammals have a long ...

Rubber Chemistry and Technology, 1934
Abstract Since the beginning of the rubber industry, sulfur dosages used for soft rubber have declined from 20 to 2 or 3 per cent customary today. The decline is still under way, and present sulfur ratios are high in comparison with what is actually required to produce satisfactory commercial vulcanization—fractions of 1 per cent. Vulcanization
