[ pol-ee-suhl-fahyd ]

noun

, Chemistry.

1. a sulfide whose molecules contain two or more atoms of sulfur.

Word History and Origins

Origin of polysulfide¹

First recorded in 1840–50; poly- + sulfide

Example Sentences

A problem of particular interest is a side reaction in which the polysulfide intermediates migrate, called shuttling, to the lithium metal anode and react with it, consuming both sulfur and lithium and leading to energy loss and rapidly reduced storage capacity.

From Science Daily

Their study also found that the intermediate Li2S6 does not directly participate in the electrochemical process but is present as a major product from side chemical reactions and contributes significantly to the unwanted polysulfide shuttling effect.

From Science Daily

However, few studies have focused on the endogenous content of polysulfide in broccoli sprouts.

From Science Daily

Dr. Kasamatsu stated, "The discovery of the significant increase in polysulfide content during the sprouting process from broccoli seeds was completely by chance and very surprising. This finding suggests that polysulfides may play an important role in the process of plant germination and growth. Further investigation of the pharmacological function of these unknown polysulfides could lead to the development of new preventive and therapeutic approaches and medicines for neurodegenerative diseases, stroke, cancer, inflammation, and other oxidative stress-related diseases."

From Science Daily

Building upon their previous work, where the research team demonstrated the abundance of polysulfide molecules in cruciferous vegetables.
