Dimethyl trisulfide (DMTS) is an organic chemical compound and the simplest organic trisulfide. It is a flammable liquid with a foul odor, which is detectable at levels as low as 1 part per trillion. Dimethyl trisulfide has been found in volatiles emitted from cooked onion, leek and other Allium species, from broccoli and cabbage, as well as from Limburger cheese, and is involved in the unpalatable aroma of aged beer and stale Japanese sake. It is a decomposition product of bacterial decomposition, including the early stages of human decomposition, and is a major attractant for blowflies looking for hosts. Dimethyl trisulfide along with dimethyl sulfide and dimethyl disulfide have been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum (Helicodiceros muscivorus). These flies are attracted to the odor of fetid meat and help pollinate this plant. DMTS contributes to the foul odor given off by the fungus Phallus impudicus, also known as the common ...

Tetradecylthioacetic acid (TTA) is a synthetic fatty acid used as a nutritional supplement. TTA acts as a peroxisome proliferator-activated receptor alpha (PPARα) agonist and increases mitochondrial fatty acid oxidation in vitro.[1] In rodent studies, TTA has been reported to have other activities such as reducing inflammation[2] and preventing high fat diet induced adiposity and insulin resistance.[3] In human clinical study, there have been mixed observations in preliminary studies. One Phase I study showed no significant changes in the blood lipids or free fatty acids[4] and another showed that TTA attenuates dyslipidemia in patients with type 2 diabetes mellitus.[1] ...

The thermodynamics for the first electron transfer step for sulfide and oxygen indicates that the reaction is unfavorable as unstable superoxide and bisulfide radical ions would need to be produced. However, a two electron transfer is favorable as stable S(0) and peroxide would be formed, but the partially filled orbitals in oxygen that accept electrons prevent rapid kinetics. Abiotic sulfide oxidation kinetics improve when reduced iron and/or manganese are oxidized by oxygen to form oxidized metals which in turn oxidize sulfide. Biological sulfur oxidation relies on enzymes that have evolved to overcome these kinetic constraints to affect rapid sulfide oxidation. Here we review the available thermodynamic and kinetic data for H2S and HS• as well as O2, reactive oxygen species, nitrate, nitrite and NOx species. We also present new kinetic data for abiotic sulfide oxidation with oxygen in trace metal clean solutions that constrain abiotic rates of sulfide oxidation in metal free solution and agree with

With the development of science and technology, new applications about nanoparticles should be explored to achieve full-scale knowledge. Therefore, in this work, the toxicity and potential application of raw cadmium sulfide nanoparticles (CdS) in vivo were further studied through ICP-OES and CTs. Surprisingly, CdS exhibited an excellent photographic property, except for finding the accumulation of CdS in the lungs, liver, spleen, and kidney with a strong dependence on time; it is also found that there were a significant uptake in the pancreas for an obvious CT imaging. And the following investigations showed that the raw CdS could damage the tissues accumulating nanoparticles. Through this work, it can be seen that the raw CdS being modified might be an excellent photographic developer for detecting cancers or other diseases.

Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately choosing the composition of the sulfide host. Main application areas are flat panel displays based on thin film electroluminescence, field emission displays and ZnS-based powder electroluminescence for backlights. For these applications, special attention is given to BaAl2S4:Eu, ZnS:Mn and ZnS:Cu. Recently, sulfide materials have regained interest due to their ability (in contrast to oxide materials) to provide a broad band, Eu2+-based red emission for use as a color conversion material in white-light emitting diodes (LEDs). The potential application of rare-earth doped binary alkaline-earth sulfides, like CaS and SrS, thiogallates, thioaluminates and thiosilicates as conversion phosphors is discussed. Finally, this review concludes with the size

A process for biooxidation of sulfides in a heap of mineral ores by freeing precious metals dispersed or occluded within said ores as pyritic or arsenopyritic sulfides and the like; the process comprises forming particulates from ore particles with an inoculate comprising bacteria capable of attacking, by biooxidation, sulfides and/or elemental sulfur in said ore particles; from these particulates a heap is constructed; and the biooxidation takes place in such heap by adding to or dispersing within the heap a leaching solution, circulating the leaching solution within the heap and recovering the precious metal values from the heap; recovery may be accomplished with a cyanide, thiourea, or a thiosulfate lixiviant.
Frank: Thank you for the comment. It is hard to answer your question because GTAC has not been very forthcoming about what its plans actually are. There are two end-members of a range of possibilities. At one end, it is possible that everything GTAC has said is true, that it has not looked at the cores, that it has no idea what is in they Tyler shale, and that this is an iron mine pure and simple. In that case the mine will uncover pyrite and apatite in the process of recovering the iron, which is a problem that has not been discussed at all by either by GTAC or the legislators. The whole rationale for creating separate laws to cover the mining of iron oxides is that iron oxide mining will not uncover sulfides. The presence of sulfides in the Tyler undermines this rationale. At the other extreme is the possibility that GTAC knows exactly what is in the Tyler and is hiding it, either to prevent the issue of sulfides being raised during debate over a bill that creates an artificial distinction ...

The six families we will investigate include the sulfides, sulfates, oxides, halides, carbonates, borates, and silicates. Sulfides and sulfates all have sulfur in the anion. For example galena is a sulfide and its composition is PbS. The sulfides mainly are metallic. The sulfates include the radical SO4 and include minerals that are nonmetallic. These can include gypsum. Some families have an anion that is related to oxygen. Oxides contain a anion that is usually a metal in combination with oxygen. For example, hematite is iron plus oxygen (Fe2O3). Carbonates include the CO3 radical and includes minerals like calcite. Borates contain the BO3 group and include minerals like borax and ulexite. Sulfates also have oxygen within its radical.. Silicates form the largest chemical class among the minerals. They contain various elements in different combination like sodium, potassium, calcium, magnesium, aluminum, and iron in combination with silicon and oxygen. They have very complex chemical structures. ...

A method for treating a heavy metal-containing liquid, such as a wastewater stream, oil for recycling, or other metal-bearing liquid, with a trithiocarbonate, particularly an alkali metal trithiocarbonate, such as sodium trithiocarbonate, to precipitate the metals as insoluble sulfides. The precipitated metal sulfides are recovered as a low volume sludge, which can be processed through standard metallurgical techniques to yield the metals in economically useful forms. Among the most unexpected results produced by this method is the lowering of the selenium content in a naturally occurring body of water from 1.0 ppm to 0.0015 ppm.

Gratonite is a rare lead sulfide mineral. It forms nice crystals that can be arranged into rosette-like clusters with projecting rhombohedral terminations. Clusters can be attractive and good specimens command large prices, mostly because of the rarity of the mineral. Gratonite is a sulfosalt, a segment of sulfides where the arsenic acts more like a metal than a non-metal and occupies a position where it is bonded to sulfurs. Also, Gratonite is the most common mineral whose symmetry is in the Trigonal Pyramidal Class. ...

The Rb-Sr dating of sphalerite is a powerful method for evaluating the timing of large-scale crustal fluid flow events and testing hydrological models. The Mississippi Valley-type Zn-Pb deposit at Blendevale, Western Australia, is the largest of several such deposits situated on the northern margin of the Canning basin on the Lennard shelf. It is hosted by the reefal facies of the Devonian (Frasnian) Pillara Limestone, flanked to the south by the Fitzroy trough, a deep half-graben. Rb-Sr isotope analysis of six sphalerites and their fluid inclusion leachares form an isochron indicating an age of 357 + or - 3 Ma (( 87 Sr/ 86 Sr) 0 = 0.7129 + or - 2), in good agreement with the average age, 355 + or - 14 Ma, of the leachate-sphalerite pairs and an isochron consisting of a sphalerite sample, its leachate, and associated host carbonate (362 + or - 12 Ma). This age renders as untenable a recently proposed model calling for basinal brine expulsion in response to a hydrocarbon generation event ...

A recently discovered, moderately thermostable Baeyer-Villiger monooxygenase, polycyclic ketone monooxygenase (PockeMO), from Thermothelomyces thermophila has been employed as a biocatalyst in a set of asymmetric sulfoxidations. The enzyme was able to catalyze the oxidation of various alkyl aryl sulfides with good selectivities and moderate to high activities. The biocatalytic performance was able to be further increased by optimizing some reaction parameters, such as the addition of 10% v v−1 of water miscible solvents or toluene, or by performing the conversion at a relatively high temperature (45 °C). PockeMO was found to display an optimum activity at sulfide concentrations of 50 mM, while it can also function at 200 mM. Taken together, the data show that PockeMO can be used as robust biocatalyst for the synthesis of optically active sulfoxides.
