We investigated the ability of zinc sulfate (5, 25, 50 mM) to inhibit the sweetness of 12 chemically diverse sweeteners, which were all intensity matched to 300 mM sucrose [800 mM glucose, 475 mM fructose, 3.25 mM aspartame, 3.5 mM saccharin, 12 mM sodium cyclamate, 14 mM acesulfame-K, 1.04 M sorbitol, 0.629 mM sucralose, 0.375 mM neohesperidin dihydrochalcone (NHDC), 1.5 mM stevioside and 0.01...

We investigated the effect of locally applied zinc on the healing of partial-thickness skin wounds in the domestic pig using two zinc compounds (zinc oxide and zinc sulfate) in two different vehicles (a gauze compress and a collagen sponge). The rate of re-epithelialization was determined morphometrically 48 and 64 hr after infliction of standardized square wounds (4.8 cm2 and 400-microns deep)...

Zinc sulfate is an inorganic compound: the sulfate salt of zinc and a good source of zinc ions. The molecular 40 formula for zinc sulfate is ZnSO4. A graphic representation of the structure of zinc sulfate is shown in figure 1 41 (Pubchem, 2014). Zinc sulfate appears geologically as a white crumbly salt efflorescence known as “goslarite.” 42 Goslarite, the heptahydrate of zinc sulfate was first...

Cobalt-catalyzed activation of methylthio-substituted N-heterocycles facilitates either cross-coupling reactions with aryl- or benzylzinc compounds or synthesis of the corresponding zinc compounds.

A xanthene-forming condensation reaction yields rhodol and rhodamine dyes carrying a zinc-binding ligand that includes the aniline-type nitrogen donor of the fluorophores. Upon zinc coordination in neutral aqueous solution, rhodol RF3 behaves as a ratiometric sensor, and rhodamine RA1 acts as a turn-off intensity-based indicator. Both fluorescent compounds bind the divalent zinc cation with mic...

Zinc sulphide thin films have been deposited with CADT using zinc chloride and zinc acetylacetonate as Zn compounds and thiourea and 1,1,3,3-tetramethylthiourea as S compounds soluted in methanol, ethanol, isopropanol and cellosolve. After optimalization of the deposition process homogeneous layers with a c-axis oriented hexagonal columnar structure with a high density (up to 96%) were obtained...
