Introduction Iodine is an essential nutrient found in seawater, seafood, and iodine-enriched food, such as iodized table salt. The most common forms of iodine in diet are iodide and iodate, with additional iodo-organic compounds providing a small fraction of bioavailable iodine. Iodine deficiency affects thyroid hormone production and leads to developmental diseases, goiter, and paralysis.1 Tab...

Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In fact, one past electroretinographic study led to the conclusion that in eels there is no change in scotopic sensitivity, with increasing sexual maturity. In the present experimen...

Objective: This study was design to determine the prevalence of IDD by measuring urinary iodine excretion among primary school age children, to assess the effect of goitrogen on urinary iodine absorption and assess the impact of salt iodization program. Methods: A questionnaire was given to all students participating in the study to be filled out by their families regarding whether or not they ...

An iodine biofortification experiment was conducted by applying potassium iodate fertilizer in soil and foliar form chitosan complex forms to investigate the growth, yield, quality uptake of shivam hybrid tomato Palaviduthi series Coimbatore region. Soil fertilization alone resulted lower fruits because is susceptible high volatilization less phytoavailability also yield poor fruits. When were ...

Two polytypic modifications of new non-centrosymmetric iodate Rb3Sc(IO3)6 are synthesized hydrothermally. Their structures demonstrate different degrees ordering and solved in the same space group, Pc, with differing choice b-axis: either 20 or 40 Å is selected from diffraction data, measured on crystals better ordering. The difference NLO properties two polytypes disclosed. Topology–symmetry a...

A promising electrochemical sensor was fabricated by the self-assembling of Pt nanoparticles (nano-Pts) on a chitosan (CS) modified glassy carbon electrode (GCE). A field-emission scanning electron microscope (FE-SEM), transmission electron microscopy (TEM) and electrochemical techniques were used for characterization of these composites. It has been found that nano-Pts are inserted into the CS...

The synthesis, crystal and band structures and optical characterizations of a new polar thallium(I) vanadyl iodate, namely Tl(VO)2O2(IO3)3, are reported. Tl(VO)2O2(IO3)3 crystallizes in the orthorhombic polar space group Ima2 (No. 46) with a = 14.1143(17), b = 10.2116(12), c = 8.0319(9) Å, V = 1157.6(2) Å(3) and Z = 4. The structure of Tl(VO)2O2(IO3)3 exhibits a 1D [(VO)2O2(IO3)3](-) chain in w...

Concentrations and species of iodine isotopes ((127)I and (129)I) provide vital information about iodine geochemistry, environmental conditions and water masses exchange in oceans. Despite extensive investigations of anthropogenic (129)I in the Arctic Ocean and the Nordic Seas, concentrations of the isotope in the Atlantic Ocean are, however, still unknown. We here present first data on (129)I ...

High-pressure synchrotron X-ray diffraction studies of cobalt iodate, Co(IO3)2, reveal a counterintuitive pressure-induced expansion along certain crystallographic directions. Raman and infrared spectroscopy, combined with density-functional theory calculations, that increasing pressure, it becomes energetically favorable for I–O bonds to increase in length over the full range pressure studied ...
