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

Furthermore, a comprehensive analysis of the polysulfides detected a number of polysulfide candidates whose structures have not yet been determined.

From Science Daily

The team found that total polysulfide content in broccoli sprouts significantly increased during germination and growth, with an approximately 20-fold increase in polysulfides on the fifth day of germination.

From Science Daily

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