Studies on solvent extraction of free hydrogen cyanide from river water
Bulletin of the Chemical Society of Ethiopia, 2007 A method for free and strongly complexed cyanide measurement in river water was developed. Recovery tests from solution with and without river water, using various solvent combinations and background control were investigated to obtain an accurate and ...

μ-Cyanido-κ2C:N-dicyanido-κ2C-bis(N-ethylethylenediamine-κ2N,N′)copper(II)copper(I)
Acta Crystallographica Section E, 2014 In the title complex, [CuICuII(CN)3(C4H12N2)2], the CuI and CuII ions and a bridging cyanide group lie on a twofold rotation axis. The CuII ion is in a slightly-distorted square-pyramidal coordination environment, with the N atoms of the two symmetry ...

Advanced Materials, EarlyView.Rapid thiol‐maleimide addition frequently outpaces mixing, resulting in heterogeneous hydrogels. S‐nitrosothiols act as thiol‐protecting groups, allowing uniform mixing with maleimide‐functionalized polymers before gelation. Sodium thiosulfate or sodium ascorbate then regenerates thiols on demand, triggering controlled thiol‐maleimide crosslinking ...

Advanced Materials, EarlyView.Aqueous ammonium‐ion batteries (AAIBs) face a hydrogen‐bond paradox: the HB network enables fast NH4+ transport but triggers water decomposition. This review dissects this dilemma, evaluates multiple electrolyte engineering strategies, and outlines four future directions for next‐generation AAIB design ABSTRACT Aqueous ammonium‐ion batteries (AAIBs ...
