Niobium-Titanium-Based Photocatalysts: Its Potentials for Free Cyanide Oxidation in Residual Aqueous Effluent

open access: yesFrontiers in Chemistry, 2020
Organic compounds are employed as additives to increase the dissolution speed of gold, in concentrations around 1 g/L when using cyanidation, thereby forming a residual aqueous effluent with high amounts of free cyanides and organic compounds, which ...

Biochemical and structural properties of cyanases from Arabidopsis thaliana and Oryza sativa. [PDF]

open access: yesPLoS ONE, 2011
Cyanate is toxic to all organisms. Cyanase converts cyanate to CO₂ and NH₃ in a bicarbonate-dependent reaction. The biophysical functions and biochemical characteristics of plant cyanases are poorly studied, although it has been investigated in a variety

Comparative Genomics of Thiohalobacter thiocyanaticus HRh1T and Guyparkeria sp. SCN-R1, Halophilic Chemolithoautotrophic Sulfur-Oxidizing Gammaproteobacteria Capable of Using Thiocyanate as Energy Source

open access: yesFrontiers in Microbiology, 2019
The genomes of Thiohalobacter thiocyanaticus and Guyparkeria (formerly known as Halothiobacillus) sp. SCN-R1, two gammaproteobacterial halophilic sulfur-oxidizing bacteria (SOB) capable of thiocyanate oxidation via the “cyanate pathway”, have been ...

Activation of the CN Single Bond in Iso(thio)cyanates by a Phosphinine‐Borane Lewis Pair: Unravelling a Complex Reaction Network

open access: diamondChemistryEurope, Volume 4, Issue 1, January 2026.
The Lewis pair 1, comprising an aromatic phosphinine and the strong Lewis acid B(C6F5)3, selectively activates the CN bonds in tBuNCO and tBuNCS. The experimental and computational studies confirmed the formation of a 1‐tBu‐phosphininium salt, acting as a key intermediate. Unlike classical frustrated Lewis pairs, this method allows the alkylation of
