195pt and 1h nmr has been used to show that addition of chlorine and bromine to [pt(cn)4]2_ in presence of perchloric acid in water results in cyanide and water scrambling with formation of eleven complexes of the type [pt(cn)4-ncl(h2o)n+1](n-1)+ (n=0, 1, 2, 3, 4). addition of nbu4oh to this solution gives (nbu4)2[pt(cn)4cl(oh)]. nmr measurements in acetone also show cyanide and hydroxyl group ...

Spent pot lining (SPL), a waste product containing cyanide, has been deposited in a landfill at an aluminum refining site in British Columbia (Canada). Since the capping of the landfill, a continuous decline of the cyanide level in the groundwater was observed for more than a decade, suggesting that natural attenuation might be taking place. The information gathered from a critical review of th...

During experiments on the effect of cyanide on the oxidation of ethanol and butyrate by dried cell preparations of Clostridium kluyveri (3), it was observed that cyanide depressed acetyl phosphate accumulation much more than the oxygen uptake. An investigation of this phenomenon led to the discovery that cyanide at rather high levels induces a rapid enzymatic acetylation of amino acids and prot...

This chemical sensor method was selected to detect cyanide in this paper. We synthesized a new reagent which can produce color change from colorless to yellow when encountering cyanide. According to this feature, this reagent can be used to identify cyanide. This reagent had also a good ability of anti-interference, the color change is not obvious when this reagent Encounter the interference io...

Green hydrogen: Cyanide-bound cobalt hydroxides in-situ grown from Prussian blue analogue Co3[Co(CN)6]2 in alkaline solution deliver excellent activity with low anodic onset potential for biomass oxidation. The performance is attributed to the cyanide group and adjacent unsaturated Co sites cooperatively promoting oxidation associated stabilization.

it has been known that cardiomyocytes possess a remarkable ability to downregulate their energy expenditure on restricted 02 supply. however it has also been speculated that an ability to suppress aerobic respiration and atp utilization could be a protective response to prolonged hypoxia. having the role of the cytochrome oxidase enzyme in mind, one can ask if its inhibition by using cyanide ha...

Superoxide reductases (SORs) are nonheme iron-containing enzymes that reduce HO(2) to H(2)O(2). Exogenous substrates such as N(3)(-) and CN(-) have been shown to bind to the catalytic iron site of SOR, and cyanide acts as an inhibitor. To understand how these exogenous ligands alter the physical and reactivity properties of the SOR iron site, acetate-, azide-, and cyanide-ligated synthetic mode...

When cassava (Manihot esculenta Crantz) root was cut into blocks and incubated under laboratory conditions, the blocks showed more widespread and more even symptoms of physiological deterioration than those under natural conditions. Thus, the tissue block system has potential for biochemical studies of natural deterioration of cassava root. The changes in cyanide content and linamarase (linamar...

The records of 255 cyanide poisoning deaths obtained from National Forensic Service (NFS) headquarters, located in Seoul of Korea, from 2005 to 2010 were retrospectively reviewed. The mean age was 41.88 ± 13.09 and range was 6~80 years (unknown in seven cases). The number of deaths of males and females were 200 and 53, respectively (unknown in two cases). The largest number of cases occurred in...
