Dark Sulfur: Quantifying unpolymerized sulfur in inverse vulcanized polymers [PDF]
, 2022 Elemental sulfur is produced as a by-product of the refining process of the petrochemicals industry. This generates an excess of sulfur each year that currently goes unused.

Sulfur and Sulfur Compounds in Plant Defence [PDF]
Natural Product Communications, 2012 The multiplicity of chemical structures of sulfur containing compounds, influenced in part by the element's several oxidation states, directly results in diverse modes of action for sulfur-containing natural products synthesized as secondary metabolites in plants. Sulfur-containing natural products constitute a formidable wall of defence against a wide

Bunsen section thermodynamic model for hydrogen production by the sulfur-Iodine cycle [PDF]
, 2009 A model for the Bunsen section of the Sulfur – Iodine thermo-chemical cycle is proposed, where sulfur dioxide reacts with excess water and iodine to produce two demixing liquid aqueous phases (H2SO4 rich and HI rich) in equilibrium.

Sulfur-bound biomarkers of a Monterey shale and a Greenland lake sediment [PDF]
, 2009 Seeking to reconstruct the biogeochemical processes that produced organic sulfur compounds in two unique depositional environments, we used the nickel boride desulfurization reaction to release hydrocarbons from sulfur-bound macromolecules not otherwise ...
