A new luminescent silver-based probe for on/off sulfide determination
(2016-01-01)
The sulfide anion is a corrosive, toxic and harmful compound found in a wide range of anoxic environments. Metal-based complexes have been used as luminescent probes for sulfide determination. However, their synthesis ...
Hemeproteins as targets for sulfide species
(Mary Ann Liebert, 2020-01-02)
The binding of sulfide to ferric hemeproteins has been described in more than 40 systems, including native proteins, mutants, and model systems. Mechanisms of sulfide binding to ferric hemeproteins have been examined by a ...
Sulfetos: por que nem todos são insolúveis?
(2010)
The solubility of sulfides is discussed in this article based on the factors that can influence this property, such as predominant type of chemical bonds and structures formed in many compounds. For soluble sulfides, ...
Scavenging of Hydrogen Peroxide by Allyl Methyl Sulfide and Diallyl Sulfide, Two Garlic Active Compounds: A Theoretical Study
(Wiley Blackwell Publishing, Inc, 2020-03)
We study potential scavenging of hydrogen peroxide by Allyl Methyl Sulfide and Diallyl Sulfide, two garlic components. The antioxidant properties of garlic are attributed to organosulfide compounds, which react with reactive ...
Synthesis of (diphenylphosphinoyl)methyl vinyl sulfides, symmetric and asymmetric divinyl sulfides from bis[(diphenylphosphinoyl)methyl] sulfide
(Georg Thieme Verlag Kg, 2011-04)
Convenient Horner-Wittig-based synthetic approaches to the preparation of (diphenylphosphinoyl)methyl vinyl sulfides as well as symmetrically and unsymmetrically substituted divinyl sulfides, are described. The syntheses ...
Poole-Frenkel effect in amorphous poly(p-phenylene sulfide)
(Wiley-Blackwell, 1996-03-01)
The conductivity of poly(p-phenylene sulfide) (PPS) amorphous samples sandwiched between metallic electrodes has been studied as a function of applied voltage, temperature, and electrode material. The voltage (U) dependence ...

Effect of sulfide concentration on autotrophic denitrification from nitrate and nitrite in vertical fixed-bed reactors
(ELSEVIER SCI LTDOXFORD, 2012)
Autotrophic denitrification coupled with sulfide oxidation represents an interesting alternative for the simultaneous removal of nitrate/nitrite and sulfide from wastewaters. The applicability of such bioprocess is especially ...
