The roles of mixed ammonium chloride and potassium additives on the growth Cs 0.1 FA 0.9 PbI 3 perovskite film are investigated along with surface treatment by an n -propylammonium iodide solution which produces interfacial buffer layer.

The catalytic activity of four metal ions the fourth period table by D.I. Mendeleev in oxidation potassium iodide with ammonium persulfate. greatest increase reaction rate is observed presence copper sulfate, least cobalt and nickel salts

Two-dimensional (2D) phenylethyl ammonium (PEA + )-methyl (MA ) lead iodide ((PEA) 2 (MA)[Pb I 7 ]) hybrid perovskite exists as temperature-dependent dimorphs exhibiting an ill-defined phase transition occurring over 150 - 200 K range. Raman scattering,...

1. The biliary excretion of [(14)C]trimophonium iodide [tri[(14)C]methyl(3-hydroxyphenyl)ammonium iodide] was studied in normal Wistar animals and in jaundiced homozygous Gunn rats. 2. In normal Wistar rats small amounts of radioactivity (approx. 3% of the dose in 4h) were excreted in bile as two glucuronide conjugates, i.e. [(14)C]trimophonium glucuronide [tri[(14)C]methyl-(3-oxyphenyl)ammoniu...

Probably the first studies of the pharmacology of quaternary ammonium compounds were made by Crum-Brown and Fraser in 1868. Burn and Dale (1915) found that, unlike nicotine, tetraethyl-ammonium chloride blocked autonomic ganglia without noticeable initial stimulation. Barlow and Ing (1948a and b), Paton and Zaimis (1948a and b), and Balaban et al. (1949) studied the properties of some chemical ...
