Direct Evidence of the Presence of Hybrid Charge Transfer State in a Perovskite Nanocrystal‐Polythiophene Blend Solid State Film

Advanced Materials Interfaces, EarlyView.
The photophysical properties of a hybrid solid state film, composed of a conjugated polymer and CsPbBr3 (zwitterionic sulfobetaine ‐capped) perovskite nanocrystals (NCs), are investigated by ultrafast spectroscopy and morphological characterization. The transient spectroscopy highlights the presence at the interface of a charge transfer state, and the ...

p‐Graphene/Quantum Dot/n‐GaAs Mixed‐Dimensional Heterostructure Junction for Ultrathin Light‐Emitting‐Diodes

Advanced Materials Interfaces, EarlyView.
Novel p‐type graphene/InAs quantum dot (QD)/n‐type GaAs mixed‐dimensional heterojunction structures are demonstrated for 1.3 µm light‐emitting diodes The p‐graphene serves as an ultrathin hole injection layer and the hybrid device shows 800 × stronger electroluminescence output powers than the reference LEDs without p‐graphene.

Tailoring the Solid Electrolyte Interphase Composition on Lithium Metal Anodes by the Choice of Ionic Liquid during Mechanochemical Modification

Advanced Materials Interfaces, EarlyView.
Roll‐pressing lithium foil in contact with ionic liquids is used to produce modified lithium anodes. The differences in performance, composition, and evolution upon cycling of the anodes depending on the ionic liquid used are highlighted, when used in combination with a classical Li‐ion electrolyte.

The Impact of Gas Cluster Ion Beam Sputtering on the Chemical and Electronic Structure of Methyl Ammonium Lead Iodide Thin Films

Advanced Materials Interfaces, EarlyView.
This study explores the impact of argon gas cluster ion beam (GCIB) sputtering on methylammonium lead iodide perovskite films. Short‐term GCIB exposure effectively cleans surfaces without degradation, unlike prolonged sputtering which degrades the sample.

Determination of Quaternary Ammonium Compounds

Journal of Pharmaceutical Sciences, 1961
Abstract The official potassium ferricyanide assays of quaternary ammonium, preparations can be modified to include a potentiometric titration with silver nitrate instead of the suggested iodometric method for the determination of the excess ferricyanide. Sodium nitrite interferes with the ferricyanide assay methods.
