Polysulfide Coordination Clusters of the Lanthanides

Angewandte Chemie International Edition, 2017
AbstractThe reaction of [(DippForm)2Ln(thf)2] with an excess of elemental sulfur in toluene resulted in the formation of the trinuclear polysulfide coordination clusters [(DippForm)3Ln3S12] (Ln=Sm, Yb; DippForm=N,N′‐bis(2,6‐diisopropylphenyl)formamidinate).

Thermometric titration of polysulfides

Analytical Chemistry, 1987
A novel calorimetric approach has been developed for analyzing mixtures of sulfides and polysulfides in aqueous solution, where the moieties HS/sup -/, S/sub 2//sup 2 -/, S/sub 3//sup 2 -/, S/sub 4//sup 2 -/, and S/sub 5//sup 2 -/ are in dynamic equilibrium.

Polysulfide regulation by zwitterionic barrier towards durable lithium-sulfur batteries.

Journal of the American Chemical Society, 2020
Rational regulation on polysulfide behaviors is of great significance in pursuit of reliable solution-based lithium-sulfur (Li-S) battery chemistry. Herein, we develop a unique polymeric zwitterion (PZI) to establish a smart polysulfide regulation in Li ...

Treatment for Hydrogen Polysulfide

Journal AWWA, 1974
Despite recent advances in water‐utility technology, operators are still receiving consumer complaints of funny‐tasting water. Presented here is a new technique to rid treated water of polysulfide taste by sulfonating and by monitoring the process with Threshold‐Odor‐Number (TON) determination.
