BACKGROUND: A batch electrochemical reactor with a rotating cylinder electrode is analysed for the transformation of sulfur dioxide into either sulfuric acid or colloidal sulfur. RESULTS: Potentiostatic experiments carried ...

Sulfur deficiency in soils has become a worldwide concern for agricultural production. This study aimed to evaluate the concequence of variable sulfur source and dosing on the nutritional status and production of Piatã ...

A nephelometric technique based on a liquid drop is described for the measurement of atmospheric sulfur dioxide. A 40-mul drop of barium chloride and hydrogen peroxide solution is suspended in a flowing-air sampling stream. ...

Sulfur management is an important issue in crop plant nutrition. Sulfur has a role in fundamental processes such as electron transport, structure and regulation. It is also associated with photosynthetic oxygen production, ...

Xylooligosaccharides (XOS) acts as a prebiotic, a food component that is not digested but stimulates the growth of beneficial microorganisms present in the intestine, such as bifidobacteria and lactobacilli, improving the ...

Production of sulfur globules during sulfide or thiosulfate oxidation is a characteristic feature of some sulfur bacteria. Although their generation has been reported in Acidithiobacillus ferrooxidans, its mechanism of ...

Oxidative addition of thiols RSH, R = CH3, CH2CH2CH3, CH2C6H5, C(CH3)3 and C6H4Br, by the complex [CpFe(dppe)1] afforded the oxidized thiolate complexes [CpFe(dppe)-SR]PF6. The reaction of [CpFe(dppe)1] with HSC6H4NH2 ...

The conversion of pastures natives to grain production in soils with low clay and organic matter levels and/or the non-replacement of the exported sulfur by crops could cause a decrease on the availability of this nutrient ...
