High‐Sublimation‐Temperature Additives for Efficient Perovskite Solar Cells via Single‐Source Evaporation

Advanced Energy Materials, Volume 16, Issue 23, 17 June 2026.
The introduction of high‐sublimation‐temperature additives during the mechanosynthesis of FAPbI3 powders enables the single‐source evaporation of phase‐pure, additive‐free FAPbI3 thin films of high optoelectronic quality. The additive‐engineered deposition process yields photovoltaic devices with stabilized efficiencies exceeding 18% for an active ...

Computational and Experimental Studies of 4-Aminoantipyrine as Corrosion Inhibitor for Mild Steel in Sulphuric Acid Solution

International Journal of Electrochemical Science, 2012
The inhibitive effect of 4-Aminoantipyrine (4-AAP) on the corrosion of mild steel in 0.5 M H2SO4 solution at 303 – 323 K was studied by weight loss measurement as well as computational techniques. Results obtained showed that 4-aminoantipyrine (4-AAP) is

Nitrite to Nitrate Spontaneous Oxidation in Suspended Aqueous Droplets

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report experimental evidence of the spontaneous formation of NO3− in suspended aqueous droplets containing NO2−, driven by hydroxyl radicals and NO2 produced by the intrinsic properties of the air‐water interface. This oxidation of nitrite anions is observed in single droplets of micrometer size using optical tweezers, with the υ1(N–O ...

Morphologically Uniform Electron Transport Layer Incorporating Conjugated Polymer for Efficient Charge Extraction in Tin Perovskite Solar Cells

Carbon Energy, Volume 8, Issue 5, May 2026.
A compact and morphologically uniform electron transport layer is created by blending PC61BM with a small amount of P3HT. The optimized architecture enables efficient charge extraction and suppresses interfacial recombination, which enhances power conversion efficiency and strengthens long‐term operational stability in tin‐based perovskite solar cells,

The anodic oxidation of thiocyanate ion dissolved as KSCN in dimethylsulphoxide

Electrochimica Acta, 1972
Abstract The anodic oxidation of SCN − ion dissolved as KSCN in dimethylsulphoxide, on platinum electrodes, was investigated at ca 25, 60 and 160°C by means of various non-stationary electrochemical techniques. At low temperatures one anodic and two main cathodic processes were found.

Thiocyanate adlayer on a gold surface: an efficient strategy for enhanced electroreduction of hydrogen peroxide [PDF]

RSC Advances
This study explores the electrochemical reduction of H2O2 on an Au electrode containing potassium thiocyanate (KSCN) in an alkaline medium. The presence of thiocyanate (SCN−) ions in the reaction system modifies the Au electrode surface (SCN−-modified Au)
