Perennial ryegrass (S23), timothy (S48), white clover (S100) and red clover (Hungaropoly), grown in culture solutions containing 0.2 x 5.0 x M-potassium iodide, showed relatively small differences in iodine uptake. The lowest uptake occurred with timothy, the species that also produced the lowest yields of dry matter. Red clover had the lowest concentration of iodine in the shoots on all treatm...

Endemic goiter is widely prevalent in the countries of Southeast Asia; the Himalayan endemic is one of the world's most extensive and severe endemics. It is accompanied in many areas of this region by endemic cretinism, deaf-mutism, and other developmental disorders and thus constitutes a significant health problem. For many years the etiology and pathogenesis of goiter in the Himalayas had rem...

In this study we present the results of an emission study of different phytoplankton samples in aqueous media treated with elevated ozone levels. Halocarbon measurements show that the samples tested released bromoform and different iodocarbons, including iodomethane, iodochloromethane and diiodomethane. Iodide and iodate levels in the liquid phase were representative of concentrations of surfac...

A number of experimental techniques have been used to study two of the equilibria which control the speciation of solutions of molecular iodine in water. These are the tri-iodide formation reaction; 12 + 1= 13and the iodate formation reaction: 312 + 3H20 = 103+ 51+ 6H+. The eqiulibria were studied at temperatures up to the region 150 to 200.C. The 13formation reaction was studied by a vapour eq...

The bandstructure was calculated by the full-potential linearized augmented plane wave method. The result reveals two important insights to the novel second harmonic generation (SHG) of alpha-phase lithium iodate (α− LiIO3) crystal: the existence of finite intraband momentum matrix elements due to the non-inversion symmetry of the crystal illuminating the potential of the intra-band transition,...

Iodine (I) biofortification of vegetables by means of soil and foliar applications was investigated in field experiments on a sandy loam soil. Supply of iodine to the soil in trial plots fertilized with potassium iodide (KI) and potassium iodate directly before planting (0, 1.0, 2.5, 7.5, and 15 kg I ha(-1)) increased the iodine concentration in the edible plant parts. The highest iodine accumu...

We have previously derived seven requirements for the formulation of effective stain etchants and have demonstrated that Fe3+, Ce4+, and VO2+ + HF solutions are highly effective at producing nanocrystalline porous silicon. Here, we show that Cl2, Br2, I2, ClO3-, BrO3-, IO3-, I-, and I3- induce etching of silicon when added to HF. However, using the strict definition that a pore is deeper than i...

Nanostructured nickel-aluminum-zirconium ternary layered double hydroxide was successfully applied as a solid-phase extraction sorbent for the separation and pre-concentration of trace levels of iodate in food, environmental and biological samples. An indirect method was used for monitoring of the extracted iodate ions. The method is based on the reaction of the iodate with iodide in acidic sol...
