Potassium Thiocyanate as Source of Cyanide for the Oxidative α‑Cyanation of Tertiary Amines

, 2016
Oxidation at the sulfur of the safe-to-handle potassium thiocyanate releases cyanide units that are trapped in the presence of co-oxidized tertiary amines to form α-amino nitriles. These cyanations work in aqueous solutions and do not require a catalyst,

Development of a Stable Electrolyte for Dendrite Suppression and High‐Performance Zn–I2 Redox Flow Battery

Small, EarlyView.
An NH4Cl additive stabilizes Zn–I2 redox chemistry in aqueous Zn–I2 redox flow batteries by suppressing iodine precipitation and mitigating zinc dendrite formation. These improve reversibility and electrolyte stability, leading to enhanced coulombic and energy efficiencies, as well as substantially prolonged cycling performance.

The Employment of Hydrogen Peroxide in Water Disinfection Poses a Threat to Aquatic Ecosystems Because of Its Toxicity to Nontarget Organisms

Environmental Toxicology, EarlyView.
ABSTRACT Hydrogen peroxide is widely used in water and wastewater treatment, particularly in advanced oxidation processes that aid in the degradation of compounds and microbial disinfection. Despite concerns about potential environmental contamination, its impact on freshwater ecosystems remains inadequately studied.
