Uptake of iodide by rat tissues is influenced by an excessive intake of bromide

The effect of an enhanced bromide intake on the uptake of iodide by tissues of rats was studied. It was found that a high level of bromide in these animals caused a marked decrease in iodide concentration in the thyroid, stomach and skin. In other organs (kidneys, liver), no decrease in iodide concentration was observed. In animals maintained under the conditions of iodine deficiency the decrease was inexpressive obviously due to the fact that iodide concentration in all their tissues was already reduced. The results indicate that the effect of an excessive bromide can manifest itself only in organs/tissues which are able to accumulate iodide. The decrease in iodide concentration is probably caused both by the competitive inhibition of an uptake of iodide by superfluous bromide, and by the rise in the renal excretion of iodide due to the excess of bromide in the organism. High uptake of iodide by skin can significantly diminish the losses of absorbed iodide since skin accounts for about 20 % of the rat body weight.

Separation of free iodide from other I-species in human serum – Quantification in serum pools and individual samples

A method for the determination of free iodide in human serum has been developed. Iodide from pooled serum samples has been separated from the organic matter by SEC, subsequently freeze-dried and analyzed by ion chromatography. Investigations for recovery and precision have been carried out and provided sufficient results. For quality assurance ICP-MS has been taken additionally as a total I-detector. The iodide results of ICP-MS agree well with IC values, Iodine containing SEC- fractions from iodide-spiked samples has shown no increased I-values except that in the iodide fractions, proving that there has been no iodide conversion into other I-species (and vice versa) during the whole procedure. Free iodide from two serum pools of different healthy persons has been determined as 2.25 and 2.43 mu g I-/l, respectively. The values are related to total iodine levels determined by ICP-MS, For comparative reasons a table of individual iodine and iodide values is presented.

Long-range correlations in iodide cluster aggregates

The morphology of tin iodide deposits grown during gas-solid transformation demonstrated long-range correlations. These iodide deposits include basically two kinds of forms: fractal structure and dendritic-like structure. The fractal structure was a sort of tin iodide cluster aggregation. Each fractal structure was composed of numerous tin iodide clusters that connected or disconnected with each other. The average size of fractal structures is between 10 and 22 mu m. The dendritic-like structure was also composed of many tin iodide clusters. These clusters aggregated and formed a dendritic pattern.

ATOMIC-FORCE MICROSCOPY OF LEAD IODIDE CRYSTAL-SURFACES

Atomic force microscopy (AFM) was used to characterize the surface of lead iodide crystals. The high vapor pressure of lead iodide prohibits the use of traditional high resolution surface study techniques that require high vacuum conditions. AFM was used to image numerous insulating surfaces in various ambients, with very little sample preparation techniques needed. Freshly cleaved and modified surfaces, including, chemical and vacuum etched, and air aged surfaces, were examined. Both intrinsic and induced defects were imaged with high resolution. The results were compared to a similar AFM study of mercuric iodide crystal surfaces and it was found that, at ambient conditions, lead iodide is significantly more stable than mercuric iodide.

Interaction of cesium iodide with an air flow at high temperatures

The behavior of cesium iodide labeled with I-131 in an air flow at 630-660 and 1200-1250 degrees C was studied. At the melting point of polycrystalline CsI only insignificant amount of iodide ion is oxidized to free iodine, whereas at 1200-1250 degrees C nearly 1-2 wt % of the initial iodide is converted into free iodine in 10 min and only several hundredths of percent of the initial iodide is oxidized to iodate ions.

Biocompatible Choline Iodide Catalysts for Green Living Radical Polymerization of Functional Polymers

Herein, nontoxic and metabolizable choline iodide analogues, including choline iodide, acetylcholine iodide, and butyrylcholine iodide, were successfully utilized as novel catalysts for green living radical polymerization (LRP). Through the combination of several green solvents (ethyl lactate, ethanol, and water), this green LRP process yielded low-polydispersity hydrophobic, hydrophilic, zwitterionic, and water-soluble bio-compatible polymethacrylates and polyacrylates with high monomer conversions. Well-defined hydrophobic-hydrophilic and hydrophilic-hydrophilic block copolymers were also synthesized. The accessibility to a range of polymer designs is an attractive feature of this polymerization. The use of nontoxic choline iodide catalysts as well as green polymerization conditions can contribute to sustainable polymer chemistry.

Capture and Recovery of Organic Iodide Species from the Product Stream of a Process for the lodative Dehydrogenation of Ethane to Ethylene

A method has been proposed for the capture and recovery of organic iodides produced in the iodative dehydrogenation of ethane to ethylene. Bench-scale experiments have identified ethyl iodide as well as vinyl iodide as the main organic iodide species at levels of several hundred ppmv in the products. The capture, recovery, and recycle of these organic iodides in an absorber-stripper system, using a heavy hydrocarbon absorbing medium, has been modeled and shown to be effective in removing these organic iodide species from the hydrocarbon product stream, reducing concentrations down to around 50 ppbv levels, which enables iodine losses from the process to be maintained at economically acceptable levels.

Copper-catalyzed cross-coupling of alkylsamarium reagents with alkyl halides

SmI2/HMPA converts alkyl iodides and bromides to alkyl samarium reagents which can be cross-coupled with primary alkyl iodides and bromides and secondary iodides in the presence of Cu(I) halides or Li2CuCl4 at room temperature. The alkylation of primary iodides gives good yields of cross-coupling products with negligible homo-coupling products. The method is especially useful for the small scale cross-coupling reactions.
