Absolute frequencies of H13C14N hydrogen cyanide transitions in 1,5 μm region with saturated spectroscopy and sub-kHz scanning laser [PDF]
, 2022 The wide span and high density of lines in its rovibrational spectrum render hydrogen cyanide a useful spectroscopic media for referencing absolute frequencies of lasers in optical communication and dimensional metrology. We determined, for the first time to the best of our knowledge, the molecular transitions' center frequencies of the H13C14N isotope

Spectroscopic study and astronomical detection of doubly 13C-substituted ethyl cyanide [PDF]
A&A 590, A93 (2016), 2016 We have performed a spectral line survey called EMoCA toward Sagittarius B2(N) between 84 and 114 GHz with ALMA. Line intensities of the main isotopic species of ethyl cyanide and its singly 13C-substituted isotopomers observed toward the hot molecular core Sgr B2(N2) suggest that the doubly 13C-substituted isotopomers should be detectable also.

Effect of supporting electrolyte on electrolytic degradation of cyanide wastewater
Zaštita Materijala, 2014 The paper describes the influence of chloride ions on the electrochemical oxidation of cyanide from wastewater. Chloride ions are added in the form of NaCl (c=0.017 mol/L), and electrochemical oxidation is carried out in a laboratory electrochemical ...

Revised gas-phase formation network of methyl cyanide: the origin of methyl cyanide and methanol abundance correlation in hot corinos [PDF]
arXiv, 2023 Methyl cyanide (CH$_3$CN) is one of the most abundant and widely spread interstellar complex organic molecules (iCOMs). Several studies found that, in hot corinos, methyl cyanide and methanol abundances are correlated suggesting a chemical link, often interpreted as a synthesis of them on the interstellar grain surfaces.

Copper and Cyanide Recovery in Cyanidation Effluents
Advances in Chemical Engineering and Science, 2011 Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as

Removal of Cyanides from Gadung (Dioscorea hispida Dennst.) Tuber Chips using Leaching and Steaming Techniques [PDF]
, 2011 Gadung (Dioscorea hispida Dennst.) has been considered as one of staple foods in Indonesia. However, its high cyanides content has limited its utilisation for commercial food production. This work is aimed to investigate the removal of cyanides content
