Disodium zinc bis(sulfate) tetrahydrate (zinc astrakanite) revisited
We present a new low-temperature refinement of disodium zinc bis-(sulfate) tetra-hydrate {systematic name: poly[tetra-μ-aqua-di-μ-sulfato-zinc(II)disodium(I)]}, [Na(2)Zn(SO(4))(2)(H(2)O)(4)](n) or Zn astrakanite, which is an upgrade of previously reported data [Bukin & Nozik (1974 ▶). Zh. Strukt. Khim.15, 712-716]. The compound is part of an isostructural family containing the Mg (the original ...
متن کاملThe Zinc-Ferro Ferrite System Revisited
Highly stoichiometric zinc ferrous ferrites Zn,F+,O, were prepared and characterized by magnetization, desacwmmodation, electrical conductivity, thermal expansion and magnetostriction measurements. The results of the magnetization measurements indicate that up till x = 0.5 the magnetic structure is collinear, which led to the highest saturation magnetizations ever found in spinel femtes. The th...
متن کاملZinc and Zinc Compounds
Zinc is an essential element in people’s diet. Too little zinc can cause health problems, but too much zinc is harmful. The U.S. Recommended Dietary Allowance (U.S. RDA) for zinc is 5 15 milligrams a day for humans. Not enough zinc in one’s diet can result in a loss of appetite, a decreased sense of taste and smell, slow wound healing and skin sores, or a damaged immune system. Young men who do...
متن کاملZinc and the common cold: a meta-analysis revisited.
The common cold has been estimated to cost the United States > $3.5 billion per year. Despite several randomized clinical trials, the effect of treating colds with zinc gluconate remains uncertain due to conflicting results. We conducted a meta-analysis of published randomized clinical trials on the use of zinc gluconate lozenges in colds using the random effects model of DerSimonians and Laird...
متن کاملImmunobiology of zinc and zinc therapy.
In a recent article in Immunology Today, Wellinghausen et al.1 reviewed the various interactions between zinc and the immune system. The authors clearly pointed out that zinc (zinc ions and/or chelated zinc) plays an important role in the maintenance of immune function. Zinc deficiency results in hypoplasia of the immune system, impaired immune response, poor wound healing, diminished T-cell de...
