An oxidative stripping treatment triggers the transition from n- to p-type photoelectrochemical behavior of zinc copper indium sulfide quantum dot electrodes. These electrodes in contact with a polysulfide solution change from photoanodic to photocathodic behavior in a certain potential range upon electrochemical treatment.

A significant Au particle size-dependent electrocatalytic effect has been shown in a sandwich type photoelectrochemical solar cell consisting of CdS quantum dot (QD)-sensitized TiO(2) photoelectrodes, Au nanoparticle (NP)-loaded SnO(2) counter electrodes, and a polysulfide electrolyte solution intervening between the electrodes.

Polysulfide resins,with trade name of  G4 and G112, with short and long chain lengths respectively, were used as reactive modifiers to toughen epoxy resin. The effects of molecular weights of G4 and G112 on impact resistance, dielectric constant, thermal conductivity as well as decomposition  heat and adhesion properties of toughened epoxy were investigated. The impact strength and the diel...

Polysulfide adsorbers and the anti-shuttle electrolyte additive lithium nitrate have been identified as key strategies in enabling high-performance lithium-sulfur batteries. However, while these two additions studied isolation, little research has conducted on how they may interact. Herein, we demonstrate that polysulfide adsorber magnesium ferrite, MgFe2O4, interferes with beneficial effects o...
