Some alchemists termed this zinc oxide lana philosophica, Latin for "philosopher's wool", because it collected in wooly tufts, whereas Other people imagined it seemed like white snow and named it nix album.[82]
Sulfur candles of almost pure sulfur were being burned to fumigate constructions and wine barrels, but are actually regarded as as well harmful for residences. Prescribed drugs[edit]
Compounds with carbon–sulfur multiple bonds are unusual, an exception remaining carbon disulfide, a risky colorless liquid that is structurally similar to carbon dioxide.
Feature papers represent the most Highly developed investigate with major prospective for high effects in the sector. A Feature
Zn, by far the most ample isotope of zinc, is extremely prone to neutron activation, currently being transmuted in the really radioactive sixty five
Furthermore, ASS with 3 unique periods was fabricated with the best femtosecond laser Bessel beam, and the average transmittance of ZnS elevated by 9.7% within the wavelength variety of five μm~12 μm for that period of 2.six μm, which indicated that the hybrid micro/nanostructure acquired superior transmittance about a broad bandwidth. Finally, the novel electric subject depth distributions all-around ASS were being simulated via the FDTD method, and also the hybrid micro/nanostructure demonstrated much more stable antireflective general performance in broadband, attributed for the interface productive dielectric result and LLFE.
Sulfur–sulfur bonds really are a structural element utilized to stiffen rubber, similar to the disulfide bridges that rigidify proteins (see biological under). In the commonest type of industrial "curing" or hardening and strengthening of pure rubber, elemental sulfur is heated With all the rubber to The purpose that chemical reactions sort disulfide bridges between isoprene models from the polymer.

This kind is metastable at area temperature and step by step reverts to the crystalline molecular allotrope, and that is not elastic. This method comes about inside of a matter of hrs to times, but can be quickly catalyzed.
Summary: Zinc blend is really a compound that comes in two kinds: sphalerite and wurtzite. They are characterized by a one:one stoichiometric ratio of Zinc to Sulfur. It maintains a tetrahedral arrangement in both varieties.
Sulfur candle at first bought for residence fumigation Elemental sulfur is amongst the oldest fungicides and pesticides. "Dusting sulfur", elemental sulfur in powdered sort, is a typical fungicide for grapes, strawberry, lots of vegetables and several other crops. It has a superb efficacy versus an array of powdery mildew conditions in addition to black place.
In electrowinning, zinc is leached with the ore focus by sulfuric acid and impurities are precipitated:[109]
