Sequential Slot-Die Deposition of Perovskite Solar Cells Using Dimethylsulfoxide Lead Iodide Ink

This work demonstrates a sequential deposition of lead iodide followed by methylammonium iodide using the industrially compatible slot-die coating method that produces homogeneous pin-hole free films without the use of the highly toxic dimethylformamide. This is achieved through the careful selection and formulation of the solvent system and coating conditions for both the lead iodide layer and the methylammonium iodide coating. The solvent system choice is found to be critical to achieving good coating quality, conversion to the final perovskite and for the film morphology formed. A range of alcohols are assessed as solvent for methylammonium iodide formulations for use in slot-die coating. A dimethylsulfoxide solvent system for the lead iodide layer is shown which is significantly less toxic than the dimethylformamide solvent system commonly used for lead iodide deposition, which could find utility in high throughput manufacture of perovskite solar cells.

DETERMINATION OF IODIDE- AND TOTAL-IODINE IN OSAKA BAY BY AN ELECTROLYTIC CONCENTRATION METHOD

Iodide- and total-iodine (Iodide + iodate) in seawaters of Osaka Bay were determined by an electrolytic concentration on glassy carbon electrode and detection with a polished Ag3SI electrode. The standard deviation of this method was within about 2%. The concentrations of iodide-iodine in seawaters of Osaka Bay were in the range from 0.10 to 0.30 pM and from 0.24 to 0.47 pM for total-iodine. Compared with those values in the open oceans, iodide was enriched in Osaka Bay, because of activities of marine organisms. While, totaliodine showed considerable uniform distribution.

Expression of the human sodium/iodide symporter (hNIS) in xenotransplanted human thyroid carcinoma

The uptake of iodide in thyroid epithelial cells is mediated by the sodium/iodide symporter (NIS). The uptake of iodide is of vital importance for thyroid physiology and is a prerequisite for radioiodine therapy in thyroid cancer. Loss of iodide uptake due to diminished expression of the human NIS (hNIS) is frequently observed in metastasized thyroid cancer. So far, no animal model for the study of radioiodine therapy in thyroid cancer has been available. Strategies to restore iodide uptake in thyroid cancer include the exploration of hNIS gene transfer into hNIS defective thyroid cancer. We have performed a stable transfection of hNIS into the hNIS defective follicular thyroid carcinoma cell line FTC133. Stabily transfected colonies exhibited high uptake of (NaI)-I-125, which could be blocked completely with sodiumperchlorate. hNIS transfected FTC133 and non-transfected cell lines injected subcutaneously in nude mice formed tumors after 6 weeks. Iodide uptake in the hNIS transfected tumor was much higher than in non-transfected tumor, but a rapid release of radioactivity from the hNIS transfected tumor was observed. Further studies are necessary to investigate the role of hNIS in relation to other thyroid specific proteins in iodide metabolism in thyroid cancer.

COMPARISON OF TWO IODINE QUANTIFICATION METHODS IN AN ARTIFICIAL SEAWATER SYSTEM HOUSING WHITE-SPOTTED BAMBOO SHARKS (CHILOSCYLLIUM PLAGIOSUM)

Iodine is an essential micronutrient for elasmobranchs in order to prevent goiter. Preventing goiter requires bioavailable iodide: either oral iodide or maintaining adequate aquarium water iodide concentrations. The objective of this study was to determine how oral and water supplementation affected iodine (I-2) and iodide (I) concentrations in artificial seawater aquaria housing captive white-spotted bamboo sharks (Chiloscyl hum plagiosum). Daily water samples were collected and free iodine (I-2) was determined using ultraviolet-absorbance spectrophotometry (a relatively simple in-house assay) and total iodide (I) via liquid chromatography (a more time- and expertise-intense quantification method) to learn the effects of supplementation. One water system received iodine and iodide supplementation in the form of 5% Lugol’s iodine solution added directly to the water, while a second water system received no supplementation. In addition, one tank of sharks in each water system received oral iodide supplementation. Results indicated that oral supplementation provides greater increases in water concentrations of bioavailable iodide (I) than direct water supplementation. In addition, the chromatographic results suggested that iodide is present in higher concentrations in the systems not receiving water supplementation. Increased iodide concentrations were detected in water samples after water changes and after oral iodide supplementation was administered, but total iodine (I-2) concentration changes were not detectable within the same time frame.

Research on the gold ore leaching in iodine-iodide system

Iodine-iodide leaching gold ore is a promising method alternative to cyanide leaching. In this paper, Eh-pH diagram of Au-I–I-2-H2O system was established through calculating the equilibrium potentials of the main chemical reactions based on the thermodynamic data of the actual iodide leaching of gold system. Gold ore leaching experiments in iodine-iodide system under different influence factors were carried out to verify the effectiveness of the Eh-pH diagram. The results indicated the diagram of Eh-pH can effectively guide the actual gold ore leaching in iodine-iodide system.
