The 1,2,3,4-thiatriazole-5-thiolate anion (TTT(-)) was found to be a strongly binding ligand for CdSe nanocrystals, quantitatively exchanging various long-chain ligands to yield stable colloidal suspensions in common polar solvents. The TTT(-) ligand thermolyzes at <100 °C to produce thiocyanate in situ, resulting in reduced quantum confinement in nanocrystal films. CdSe(TTT) possesses far high...

This study of objective measurement of smoking behaviour reports the findings from a sample of 421 children aged 10 and 11 years from Sheffield. Saliva thiocyanate determination did not provide a satisfactory objective method of validating the self-reported smoking of children in this age group. There was a trend (non-significant) for non-smoking children from homes in which a close relative sm...

Patients with subacute combined degeneration who smoked had significantly lowered plasma thiocyanate levels than control smokers, but plasma thiocyanate levels in non-smoking patients with neurological disease due to vitamin B1, deficiency were not significantly different from control values. The results provide no support for the hypothesis that chronic cyanide intoxication is responsible for ...

Neutron diffraction and magnetic property measurements reveal that Cr[Bi(SCN) 6 ], a metal thiocyanate perovskite-analogue with face-centred cubic lattice, orders magnetically at 4.0(2) K shortest through-bond path of 15.1 Å.

The affinities of a series of biologically relevant ions for a hydrated phospholipid membrane were investigated using molecular dynamics simulation. Interactions of molecular ions, such as guanidinium, tetramethylammonium, and thiocyanate with the bilayer were computationally characterized for the first time. Simulations reveal strong ion specificity. On one hand, ions like guanidinium and thio...

The most commonly used protocol of the RNA isolation, the guanidine thiocyanate method, was unsuitable for recalcitrant plant tissues containing a large amount of storage proteins and secondary metabolites. We demonstrated that RNA could bind to the silica particles, which have been used successfully in DNA isolation from various sources, under a high concentration of NaCl in the presence of et...

The nitrile stretching mode of the thiocyanate moiety is a nearly ideal probe for measuring the local electric field arising from the organized environment of the interior of a protein. Nitriles were introduced into three proteins: ribonuclease S (RNase S), human aldose reductase (hALR2), and the reaction center (RC) of Rhodobacter capsulatus, through a facile synthetic scheme for the transform...

In the performance of routine determinations of serum chloride by the automated method, which depends on halide displacement of mercury from the thiocyanate to allow formation of ferric thiocyanate complex, 4 cases of bromide poisoning were detected. Experimental evidence shows the halide substitution to be an equilibrium, with higher formation constants for the heavier halide ions. As a result...

1-Benzyl-2-(methylthio)-imidazole-5-ketone is obtained in a few simple steps starting from thiocyanate and glycine amide (glycin). Subsequent treatment with diethyl phosphorocyanidate and functional group manipulations gives 1-benzyl-5-chloromethyl-imidazolium chloride. This compound is converted under mild O'Donnell conditions into the corresponding L-histidine derivative. After deprotection L...
