Photochemical Degradation of Cyanides and Thiocyanates from an Industrial Wastewater

Molecules, 2019
We have explored the simultaneous degradation of cyanides and thiocyanate present in wastewaters from a cokemaking factory using photoassisted methods under varied illumination conditions (from simulated solar light to UV light).

Lattice Dynamics and Thermal Expansion Behavior in Metal Cyanides, MCN (M=Cu, Ag, Au): Neutron Inelastic Scattering and First Principles Calculations [PDF]

Phys. Rev. B 93, 134307 (2016), 2015
We report measurement of temperature dependence of phonon spectra in quasi one-dimensional metal cyanides MCN (M=Cu, Ag and Au). Ab initio lattice dynamics calculations have been performed to interpret the phonon-spectra as well as to understand the anamolous thermal expansion behavior in these compounds. We bring out the differences in the phonon mode

Dimethylstibine cyanide, an analogue of cacodyl cyanide [PDF]

Proceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1926
The combination of cyanogen bromide and organic arsines has been studied by Steinkopf and collaborators, who found that triethylarsine furnished an unstable cyanobromide hydrolysed by air to triethylarsine hydroxybromide, although the unhydrolysed product, triethylarsine cyanobromide, was eventually isolated in a special apparatus.

The cometary composition of a protoplanetary disk as revealed by complex cyanides [PDF]

Nature, 2015
Observations of comets and asteroids show that the Solar Nebula that spawned our planetary system was rich in water and organic molecules. Bombardment brought these organics to the young Earth's surface, seeding its early chemistry.

A geometrical model for Mixed cyanide crystals [PDF]

J. of Non-Crystalline Solids {235-237} (1998) 570-575, 1999
A model of diluted random field sustained by quenched volume deformations is shown to reproduce puzzling physical features found in X(CN)_{x}Y_{1-x} mixed cyanide crystals. X is an alkali metal (K, Na or Rb) and Y is a spherical halogen ion (Br, Cl or I).

Detection of a branched alkyl molecule in the interstellar medium: iso-propyl cyanide [PDF]

Science 345, 1584 (2014), 2014
The largest non-cyclic molecules detected in the interstellar medium (ISM) are organic with a straight-chain carbon backbone. We report an interstellar detection of a branched alkyl molecule, iso-propyl cyanide (i-C3H7CN), with an abundance 0.4 times ...

Impact of Mining Activity upon Environment in Roşia Montană [PDF]

Romanian Review of Regional Studies, 2008
Roşia Montană is the greatest gold ore in Romania and one of the greatest in Europe, and its exploitation has been carried out since Antiquity up to nowadays. If the traditional extraction and processing technologies had a minimal impact upon environment,

Biomass burning and urban air pollution over the Central Mexican Plateau [PDF]

Atmospheric Chemistry and Physics, 2009
Observations during the 2006 dry season of highly elevated concentrations of cyanides in the atmosphere above Mexico City (MC) and the surrounding plains demonstrate that biomass burning (BB) significantly impacted air quality in the region. We find that

Various injury patterns due to combustion (typical but unfamiliar to physicians and easy to miss) in Korea: a case report [PDF]

Journal of Trauma and Injury, 2023
Patients transported from fire sites may exhibit various injury patterns. Major trauma, skin burn, inhalation burn, and carbon monoxide poisoning are typical injuries. However, most physicians may be unfamiliar that cyanide poisoning can frequently occur
