Mercury/oxygen reaction mechanism over CuFe 2 O 4 catalystYingju YangJing LiuJunyan DingYingni YuJunying Zhang
Oxygen-hydrogen titrations of a platinum black show that the stoichiometry of the reaction is variable. Blocking of the surface by mercury reduces the titre. The formation of the alloy PtHg is postulated, with the platinum at the surface of the alloy retaining reactivity for the titration reacti...
The atmosphere of Mercury is a "surface-bound exosphere, essentially a vacuum." It contains 42% oxygen, 29% sodium, 22% hydrogen, 6% helium, 0.5% potassium, with possible trace amounts of argon, carbon dioxide, water, nitrogen, xenon, krypton and neon, according to NASA. Mercury's orbit...
Indeed, where the study of condensable vapours is involved it may be necessary to utilize alternative protective devices (for example, gold foil) or to eliminate mercury from the system entirely.doi:10.1038/197284b0CHARMAN, H. BDELL, R. MNature Publishing Group UKNature...

Mercury (Hg) toxicity is governed by cellular thiol compounds and its capacity to generate reactive oxygen radicals and oxidative stress. Selenium (Se) plays a key role in the prevention of the toxic effects of Hg by modulating the activity of several Se-dependent enzymes, including glutathione ...
The energy barriers of Hg0oxidation by oxygen on Fe- and Mn-terminated MnFe2O4surfaces are 206.37 and 76.07kJ/mol, respectively. Mn-terminated surface is much more favorable for Hg0oxidation than Fe-terminated surface. In the whole Hg0oxidation process, the reaction between adsorbed mercury ...
The low THg concentrations in fish were attributed to the storage capacity, high oxygen concentrations and high organic matter content of the wetlands surrounding Thruston Bay. However, caution is required because the storage capacity and the methylation rates present in the wetlands of Thruston Bay...
