A probe with aggregation induced emission characteristics for screening of iodide

The dilution controlled aggregation enhanced emission of spherically aggregated form of a triazole based probe dies down upon detecting iodide over other inorganic anions. The sensing is realised as a dynamic quenching mechanism dominated event. Being highly selective for iodide, the probe finds application in the detection of iodide in human urine.

Active transport and accumulation of iodide by newly isolated marine bacteria

Iodide (I-)-accumulating bacteria were isolated from marine sediment by an autoradiographic method with radioactive (125)1-. When they were grown in a liquid medium containing 0.1 muM iodide, 79 to 89% of the iodide was removed from the medium, and a corresponding amount of iodide was detected in the cells. Phylogenetic analysis based on 16S rRNA gene sequences indicated that iodide-accumulating bacteria were closely related to Flexibacter aggregans NBRC15975 and Arenibacter troitsensis, members of the family Flavobacteriaceae. When one of the strains, strain C-21, was cultured with 0.1 muM iodide, the maximum iodide content and the maximum concentration factor for iodide were 220 +/-3.6 (mean +/- standard deviation) pmol of iodide per mg of dry cells and 5.5 x 10(3), respectively. In the presence of much higher concentrations of iodide (1 muM to 1 mM), increased iodide content but decreased concentration factor for iodide were observed. An iodide transport assay was carried out to monitor the uptake and accumulation of iodide in washed cell suspensions of iodide-accumulating bacteria. The uptake of iodide was observed only in the presence of glucose and showed substrate saturation kinetics, with an apparent affinity constant for transport and a maximum velocity of 0.073 p,M and 0.55 ptnol min(-1) mg of dry cells(-1), respectively. The other dominant species of iodine in terrestrial and marine environments, iodate (10(3)(-)), was not transported.

Thermodynamics analysis of indium iodide polycrystal synthesis

According to the thermodynamics analysis, the molar enthalpy change, the molar entropy increase, the Gibbs free energy change and the balance constant of indium iodide polycrystal synthesis reaction were calculated in order to evaluate the feasibility of reaction temperature on 653 K. After the temperature 653 K was applied in the synthesis experiment, indium iodide polycrystal was successfully obtained by the two-zone vapor transporting method. The result of X-ray diffraction analysis indicates the temperature 653K can be used for indium iodide polycrystal synthesis.

Effect of annealing on the laser induced photoluminescence behavior of template-synthesized silver iodide nanowires

Silver iodide nanowires have been fabricated using non-galvanic template synthesis technique. The effect of annealing on the laser induced photo luminescent behavior of silver iodide nanowires has been studied. It is established that due to annealing, emission wavelength of silver iodide nanowires change. In comparison with un-annealed nanowires, the emission wavelength is found to decrease with the increase in annealing temperature and annealing time as well. These studies are very important as silver iodide is a very useful candidate for photography applications.

THE INFLUENCE OF IODIDE-IONS ON PHOTOELECTRON BEHAVIORS OF T-GRAIN AGBR(I) EMULSION

The experimental observation shows that photoconductivity decay kinetics in T-Grain AgBr(I) emulsion obeys the first-order reaction rule which is not only affected by addition of iodide, however, significantly affects the mean lifetime of photoelectrons. With the increase of iodide content and the bulk-to-edge location of iodide distribution, the lifetime of photoelectrons decreases successively. This fact indicates that for T-Grain AgBr(I) emulsion photoelectron behaviors are affected not only by iodide concentration but also by iodide distribution and location in the grains.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2043-57-4, in my other articles.

Kinetics of acute and chronic iodine excess

Iodine plays an important role in thyroid physiology resulting from its importance as a requisite substrate for the synthesis of thyroid hormones and from its action as a regulator of thyroid function. Following intestinal absorption, inorganic iodide is largely confined to the extracellular fluid. Serum concentrations of inorganic iodide well reflect the amount of iodine present in the extracellular compartment. Since serum inorganic iodide levels are important determinants of thyroid iodine uptake, serum iodide measurement offers a valuable tool for the investigation of many basic and clinical aspects of thyroid iodine metabolism. Here we summarize important aspects of iodine metabolism and focus selectively on technical aspects of serum inorganic iodide measurement and on the kinetics of inorganic iodide in various states of iodine excess. Presently, paired-ion, reversed-phase HPLC with electrochemical detection is obviously the best method for measurement of serum inorganic iodide being highly sensitive, easy to perform, and almost completely insensitive to interfering substances. Using this method, we could demonstrate an acute increase of serum inorganic iodide during the administration of large amounts of iodide as Lugol’s solution given preoperatively in patients with Graves’ hyperthyroidism. In patients under treatment with the iodine containing drug amiodarone (n=37), serum inorganic iodide levels were highly elevated (range 3.5-208.2 mu g/dl, median 36.6 mu g/dl). Serum concentrations of inorganic iodide were correlated neither to the daily amiodarone dose, nor to the serum levels of amiodarone.

Optical absorption spectra of lead iodide nanoclusters

Optical absorption spectra of nanoclusters of lead iodide, synthesized by the colloidal technique, have been investigated. It is shown that the absorption peaks are due to different orders of interband transitions of a nominally single size of particles rather than the first-order transitions of a number of discrete sizes of particles, as reported earlier. The model used to explain the spectra of lead iodide has also been used to account for the optical absorption peaks of colloidal mercuric iodide and bismuth tri-iodide. [S0163-1829(98)01443-X].
