J. Marvin Herndon, a geophysicist at Transdyne Corp. in San Diego, California, suggests conducting similar tests on calcium sulfide and magnesium sulfide, two minerals that are thought to float atop the liquid iron in Earth's core and could be obscuring certain seismic observations of the planet's interior, preventing more precise models of its structure.
Silicon carbide (SiC), amorphous or graphitic carbon (C) and, in some cases, a solid-state feature at 30 μm, previously thought to be due to magnesium sulfide (MgS; Hony et al., 2002; Zhang et al., 2009), are seen in the IRS spectra of carbon-rich AGB stars in the LMC (Zijlstra et al., 2006) and the SMC (Sloan et al., 2006b).
For this purpose magnesium ferrite-copper sulfide chalcogenide was synthesized and employed as an efficient nanosorbent.
Because all Na+ (sodium) and K+ (potassium) and many Ca2+ (calcium) and Mg2+ (magnesium) salts of chloride, sulfide, and carbonate are readily soluble, it is this set of metal ions that contributes most to soil salinity.
Construction of a chemical plant using solar evaporation to extract sodium chloride, sulfide, chlorate, and magnesium oxide started in 1980 near Lake Qārūn.
The first flash lamp used in photography was invented in Germany in 1887; it consisted of a trough filled with Blitzlichtpulver ("flashlight powder"), a mixture of magnesium, potassium chlorate, and antimony sulfide.
Calcium, magnesium, potassium, sodium, chloride, and sulfide concentrations increase with depth to 25.5 cm and remain constant at greater depths.
In addition to the carbon source, the in silico minimal medium used for simulations contained water (h2o), ammonia (nh4), sulfate (so4), phosphate (pi), calcium (ca2), ferrous iron (fe3), hydrogen sulfide (h2s), potassium (k), magnesium (mg2), pantothenate (pnto-r), and nicotinate D-ribonucleotide (nmn).
PTT-plated magnesium alloys showed outstanding adhesion to poly phenylene sulfide) (PPS) compounds during injection molding in 140 °C.
Water hardness arises due to the presence of cations such as calcium and magnesium and anions such as bicarbonates, chlorides and sulfides (Ravikumar et al. 2011).
