Distribution of methyl iodide, ethyl iodide, bromoform, and dibromomethane over the ocean (east and southeast Asian seas and the western Pacific)

Ambient concentrations of four marine-derived halocarbons (methyl iodide, ethyl iodide, bromoform and dibromomethane) and two man-made halocarbons (trichloroethylene and tetrachloroethylene) were measured during western Pacific cruises and east and southeast Asian cruises. Ethyl iodide was detected in the atmosphere for the first time and was identified as an atmospheric iodine source compound. Bromoform concentrations were positively correlated with those of dibromomethane, and methyl iodide showed variations similar to those of ethyl iodide. However, there was no correlation between the bromocarbons and the iodocarbons. The concentrations of methyl iodide and ethyl iodide changed more markedly, possibly owing to higher rates of photodecomposition of iodocarbons.

The influence of the precipitation method on defect formation in multishell AgBrI (111) tabular crystals.

Multishell tabular grains have a higher speed than pure AgBr tabular grains. Usually the shells differ in size and iodide content, but also the precipitation method for the iodide containing shells has an influence on the iodide incorporation. A TEM investigation was performed to determine the defect structure of multishell AgBr (111) tabular crystals containing a shell with a low iodide concentration and one with a high iodide concentration. The twins that induce tabular growth and stacking fault contrast in the region of the iodide shells have been observed, similar to previously studied AgBr/Ag(Br,I) coreshell crystals. Moreover in some of the crystals dislocations have been observed, sometimes even an entire network. The number of dislocations formed varies for the different methods of iodide addition. Also variations in average thickness between the different iodide addition methods have been observed. A higher number of dislocations and thicker crystals point towards a higher local concentration of iodide. These observations allow deciding which iodide incorporation method is most useful for a preferred dislocation pattern.

SYNTHESIS AND CHEMISTRY OF SECONDARY ALKYL IODIDE COMPLEXES OF THE FORMULA [(ETA-5-C5H5)RE(NO)(PPH3)(ICHRR’)]+BF4-

Reactions of deuterodichloromethane complex [(eta-5-C5H5)Re(NO)(PPh3) (ClCD2Cl)]+BF4- with (a) isopropyl iodide, (b) sec-butyl iodide, (c) cyclopentyl iodide, and (d) cyclohexyl iodide give secondary alkyl iodide complexes [(eta-5-C5H5)Re(NO) (PPh3)(ICHRR’)]+BF4- (3a-d) in good to high NMR yields, depending upon the quantity of alkyl iodide employed. These compounds are much less stable than analogous primary alkyl iodide complexes, but analytically pure 3d can be isolated from the reaction of (eta-5-C5H5)Re(NO)(PPh3)(CH3) and HBF4.OEt2 in neat cyclohexyl iodide (73%). Complex 3d decomposes in CD2Cl2 to give cyclohexyl fluoride, cyclohexene (74% total) and bridging halide complexes [(eta-5-C5H5)Re(NO)(PPh3)]2X+BF4- (X = I, 33%; Cl, 36%). The formation of cyclohexyl fluoride suggests BF4- participation in carbon-iodine bond cleavage. Reaction of 3d and PPh3 gives the substitution product [Ph3PC6H11]+BF4- (24%), cyclohexyl fluoride (24%), cyclohexene (30%) and (eta-5-C5H5)Re(NO)(PPh3)(I) (7, 95%). An analogous reaction of 3d and PPN+BR- gives cyclohexene (57%) and 7 (99%).

Dynamic iodide trapping by tumor cells expressing the thyroidal sodium iodide symporter

The thyroidal sodium iodide symporter (NIS) in combination with various radioactive isotopes has shown promise as a therapeutic gene in various tumor models. Therapy depends on adequate retention of the isotope in the tumor. We hypothesized that in the absence of iodide organification, isotope trapping is a dynamic process either due to slow efflux or re-uptake of the isotope by cells expressing NIS. Iodide efflux is slower in ARH-77 and K-562 cells expressing NIS compared to a thyroid cell line. Isotope retention half times varied linearly with the number of cells expressing NIS. With sufficient NIS expression, iodide efflux is a zero-order process. Efflux kinetics in the presence or absence of perchlorate also supports the hypothesis that iodide re-uptake occurs and contributes to the retention of the isotope in tumor cells. Iodide organification was insignificant. In vivo studies in tumors composed of mixed cell populations confirmed these observations. (C) 2004 Elsevier Inc. All rights reserved.

Sorption characteristics of iodide on chalcocite and mackinawite under pH variations in alkaline conditions

In terms of long-term safety for radioactive waste disposal, the anionic iodide (1-129) with a long half-life (1.6 x 10(6) yr) is of a critical importance because this radionuclide migrates in geological media with limited interactions. Various studies have been performed to retard the iodide migration. Recently, some minerals that are likely generated from waste container corrosion, have been suggested to have a considerable chemical interaction with iodide. In this study, chalcocite and mackinawite were selected as candidate minerals for underground corrosion materials, and an iodide sorption experiment were carried out. The experiment was performed under anoxic and alkaline conditions and the pH effects on the iodide sorption were investigated in the range of pH 8 to 12. The results showed that both minerals demonstrated a noticeable sorption capacity on iodide, and the distribution coefficient (K-d) decreased as the pH increased in the experimental condition. In addition, when the alkalinity increased higher than a pH of 12, the sorption capacity of both minerals decreased dramatically, likely due to the competition of hydroxy ions with the iodide. This result confirmed that chalcocite was an especially good sorbing media for iodide under alkaline conditions with a pH value of less than 12.

Polycrystalline Mercuric Iodide Photodetectors for Cesium Iodide Scintillators

We have fabricated thin films of polycrystalline mercuric iodide for use as photodetectors coupled to cesium iodide scintillators. The compound semiconductor mercuric iodide has a large band gap (2.13 eV) causing a peak in its quantum efficiency (570 nm) which is well matched to the output of cesium iodide (550 nm). Single crystal mercuric iodide photodetectors coupled to cesium iodide have demonstrated a full width at half maximum (FWHM) energy resolution of 4.58% at 662 keV. Single crystals providing sufficient surface areas for coupling with scintillators; are difficult to grow and are therefore cost prohibitive to use in large field of view applications. However, polycrystalline films can be fabricated quickly and cheaply on a variety of surfaces including curved ones. We have therefore developed a thermal vapor transport method of growing polycrystalline mercuric iodide films onto transparent glass substrates coated with indium tin oxide. A palladium thin film is thermally evaporated on top of the film and the photodetectors; are operated at low voltage (up to 0.4 V/mu m) demonstrating the first use of polycrystalline mercuric iodide as a photodetector. The polycrystalline mercuric iodide films have a high resistivity producing a very low dark current typically about 1 nA per square cm at 0.4 V/mu m. When coupled to cesium iodide a FWHM energy resolution of 9% at 662 keV is obtained. The quantum efficiency at 570 nm is about 40% as compared to single crystal mercuric iodide which is 80%. We are currently optimizing the growth method to improve the quantum efficiency with the ultimate goal of obtaining an energy resolution close to that of single crystal performance.

Bromide and iodide selectivity in membrane capacitive deionisation, and its potential application to reduce the formation of disinfection by-products in water treatment

The formation of toxic disinfection by-products during water disinfection due to the presence of bromide and iodide is a major concern. Current treatment technologies such as membrane, adsorption and electrochemical processes have been known to have limitations such as high energy demand and excessive chemical use. In this study, the selectivity between bromide and iodide, and their removal in membrane capacitive deionisation (MCDI) was evaluated. The results showed that iodide was more selectively removed over bromide from several binary feed waters containing bromide and iodide under various initial concentrations and applied voltages. Even in the presence of significant background concentration of sodium chloride, definite selectivity of iodide over bromide was observed. The high partial-charge transfer coefficient of iodide compared to bromide could be a feasible explanation for high iodide selectivity since both bromide and iodide have similar ionic charge and hydrated radius. The result also shows that MCDI can be a potential alternative for the removal of bromide and iodide during water treatment. (C) ‘2019 Elsevier Ltd. All rights reserved.
