Study on the Passivation of Defect States in Wide-Bandgap Perovskite Solar Cells by the Dual Addition of KSCN and KCl [PDF]

Nanomaterials
Wide-bandgap (WBG) perovskite solar cells (PSCs) are critical for high-efficiency tandem photovoltaic devices, but their practical application is severely limited by phase separation and poor film quality. To address these challenges, this study proposes

Aqueous Biphasic Systems Based on Tetrabutylammonium Bromide for Extraction and Determination of Azorubine, Allura Red, Sunset Yellow, Tartrazine and Fast Green in Food Samples [PDF]

Molecules
Aqueous biphasic systems (ABSs) based on tetrabutylammonium bromide (TBABr) and potassium thiocyanate or citrate (K3Cit) were proposed as “green” tools for liquid–liquid microextraction of Azorubine, Allura Red, Sunset Yellow, Tartrazine and Fast Green ...

The Role of Polarizability in Isoelectronic Ions: The Case of Pseudohalides [PDF]

Molecules
Specific ion effects are widespread and have been studied for over a century, yet they remain poorly understood. Terms like “kosmotropes” and “chaotropes” are convenient rules of thumb but the frequent reversal of the Hofmeister series implies their ...

Paired Electrolysis Enabled Cyanation of Diaryl Diselenides with KSCN Leading to Aryl Selenocyanates

Molecules, 2023
The first example of paired electrolysis-enabled cyanation of diaryl diselenides, with KSCN as the green cyanating agent, has been developed. A broad range of aryl selenocyanates can be efficiently synthesized under chemical-oxidant- and additive-free ...

Potentiostatic transients related to the electrolytic oxidation of KSCN and mixtures of NaSCN + KSCN melts on polycrystalline platinum [PDF]

Journal of Electroanalytical Chemistry and Interfacial Electrochemistry, 1985
Potentiostatic transients related to the electrolytic oxidation of molten thiocyanate (KSCN and KSCN + NaSCN, 0.7:0.3 mol/mol) on polycrystalline Pt obtained in the 168–290°C range are interpreted in terms of a nucleation and growth mechanism under diffusion control which involves the formation of two different products constituting the passivating ...

Investigation of the effects of the magnetic field on the anodic dissolution of alloy 690 in SO42− + SCN− solution using digital holography

Heliyon, 2023
Digital holography has been employed for in situ observation of dynamic processes occurring at the electrode|electrolyte interface during the anodic dissolution of Alloy 690 in solutions containing SO42− + SCN− with or without magnetic field (MF). It was

Synthesis, crystal structure and properties of chloridotetrakis(pyridine-3-carbonitrile)thiocyanatoiron(II)

Acta Crystallographica Section E: Crystallographic Communications, 2023
Reaction of FeCl2·4H2O with KSCN and 3-cyanopyridine (pyridine-3-carbonitrile) in ethanol accidentally leads to the formation of single crystals of Fe(NCS)(Cl)(3-cyanopyridine)4 or [FeCl(NCS)(C6H4N2)4].

Synthesis, Characterization and Antibacterial Properties of Complex [Ag(SCN)(2-NH2py)] [PDF]

E3S Web of Conferences
The reaction of AgSCN with 2-aminopyridine in ammonia solution produces the colorless crystal of catena-poly [Ag(SCN))(C6H5N2)]n. The crystals were characterized by FTIR analysis and single crystal X-Ray diffraction.

Novel one-pot process for the synthesis of ethyl 2-imino-4-methyl-2,3-dihydrothiazole-5-carboxylates [PDF]

Journal of the Serbian Chemical Society, 2015
A facile one-pot two-step process for the synthesis of ethyl 2-imino-4-methyl-2,3-dihydrothiazole-5-carboxylates via the cyclocondensation of ethyl 2-thiocyanatoacetoacetate with a variety of hydrazine and hydrazide derivatives has been ...
