A novel heteroleptic Ru II complex (BTC-2) employing 5,5 ′ -(2,2 ′ -bipyridine4,4 ′ -diyl)bis (thiophene-2-carboxylic acid) (BTC) as the anchoring group and 4,4 ′ dinonyl-2,2 ′ -bipiridyl and two thiocyanates as ligands is prepared. The photovoltaic performance and device stability achieved with this sensitizer are compared to those of the Z-907 dye, which lacks the thiophene moieties. For thin...

We describe a method for rapid and specific measurement of thiocyanate in serum or urine. We separate thiocyanate from interfering compounds by adsorbing it on an anion-exchange resin that has special affinity for thiocyanate, then eluting with sodium perchlorate. The eluted thiocyanate is quantified by a modified König reaction, sodium hypochlorite being used as the chlorinating reagent. Analy...

Atomic resolution STM images of Au( 11 1) treated with solutions of Na2.9, H2S, or NaSCN display patterns of atoms in the shape of squares with nearest-neighbor distances of 0.27 f 0.3 nm. QCM data demonstrate that Au dissolves in aqueous solutions of sulfide and thiocyanate with 02 present. The square pattern observed is ascribed to images of Au atoms on a reconstructed Au( 11 1) surface cause...

At the end of a multifactorial cardiovascular preventive trial serum thiocyanate was measured in random samples of 1035 cases and 1087 controls. A cut-off point 0.45 mg/dl (77.6/mumol/l) gave a sensitivity of 82.1% among the cigarette smokers in the control group and a specificity of 91.0% among the non-smokers. When the intervention and control groups are compared in terms of self-reported smo...

INTRODUCTION The enzyme rhodanese, which catalyzes the for mation of thiocyanate from cyanide and thiosulfate, is of interest to the cancer problem for reasons to be mentioned below. The administration of nitriles causes an increase in the thiocyanate level of the blood and in its urinary excretion. In seeking an explanation for the growth-retarding effect of certain substituted malononitriles ...

The Colorado River is contaminated with low levels of perchlorate. Perchlorate has the potential to disrupt thyroid function by inhibiting the uptake of iodide. Brassica are rich sources of thiocyanate and nitrate, also inhibitors of iodide uptake. This study was conducted to estimate potential human exposure to perchlorate, thiocyanate, and nitrate from Brassica sp. irrigated with Colorado Riv...
