Unique response of polysulfide in serum albumin to oxidative stress [PDF]

Scientific Reports
Supersulfide species have been identified as molecules that have catenated sulfur atoms as persulfides (R-SSH) and polysulfides (R-SSnH). The physiological activities of intracellular supersulfides have been widely studied, but little is known about the ...

Tunnel Structure Enhanced Polysulfide Conversion for Inhibiting “Shuttle Effect” in Lithium-Sulfur Battery

Nanomaterials, 2022
The Lithium sulfur (Li-S) battery has a great potential to replace lithium-ion batteries due to its high-energy density. However, the “shuttle effect” of polysulfide intermediates (Li2S8, Li2S6, Li2S4, etc.) from the cathode can lead to rapid capacity ...
