16 S (Sulfur Element) Flashcard of Sulfur. Sulfur is abundant, pale yellow, odorless, tasteless, crystalline solid non metal, which is insoluble in water but soluble in carbon disulfide (CS2). It is a good insulator. In every state (liquid, solid, or gas), sulfur occurs in more than one allotropic form or modification.

Sulfur exists in nature as elemental deposits as well as sulfides of iron, zinc, lead, and copper, and sulfates of sodium, calcium, barium, and magnesium. Hydrogen sulfide is often a component of natural gas and occurs in many volcanic gases, like those shown in Figure 18.58. Sulfur is a constituent of many proteins and is essential for life.

While pristine graphene with naturally occurring edges and vacancies (i.e., intrinsic defects) exhibits a non-zero magnetic moment, the addition of S-dopants was found to quench this magnetic ordering. In fact, we found that sulfur doping drastically changes the magnetic behavior of the as-prepared samples.

Von Guericke included an illustration of his sulfur globe, similar to this one, in his 1672 treatise. He first made the globe, however, in the 1660s. More than a decade later, he noticed that sometimes when he rotated the sulfur globe, it glowed. Although von Guericke did not understand it, the glowing he observed was electroluminescence, the ...

The effects of sulfur content and slab reheating temperature on the magnetic properties of four fully processed nonoriented electrical steels have been investigated. Four slabs of nonoriented electrical steels with sulfur content in the range of 0.0006–0.0126 wt% were reheated to 1100, 1200, and 1300 °C, respectively.
