A Parallel Simulator for Mercury (Hg) Porosimetry
A parallel simulator, based on the Dual Site-Bond Model of complex media, is developed to study Hg intrusion and extrusion processes in the myriad of voids contained in a porous network. In order to reduce the requirements in RAM and computing resources, the porous network is partitioned into several sub-networks distributed in different cluster processors. The simulator uses shared memory to p...
متن کاملBacterial oxidation of mercury metal vapor, Hg(0).
We used metalloregulated luciferase reporter fusions and spectroscopic quantification of soluble Hg(II) to determine that the hydroperoxidase-catalase, KatG, of Escherichia coli can oxidize monatomic elemental mercury vapor, Hg(0), to the water-soluble, ionic form, Hg(II). A strain with a mutation in katG and a strain overproducing KatG were used to demonstrate that the amount of Hg(II) formed ...
متن کاملMercury(II)-mediated formation of imide-Hg-imide complexes.
Three different kinds of cyclic imides with imido protons are chosen to interact with Hg(II): succinimide, the simplest cyclic imide (five-membered ring); phthalimide (conjugated five-membered ring); and 1,8-naphthalimide (conjugated six-membered ring). Based on the results of MS, (1)H-NMR, XPS, IR spectroscopy and fluorescence response analyses, it is suggested that N-unsubstituted cyclic imid...
متن کاملSynthesis and crystal structure of mercury (II) complex Hg (Meca2en) I2
The mercury (II) complex, Hg (Meca2en)I2 (1), containing bidentate Schiff base ligand Meca2en = N,N′-bis[(E)-2-benzylidenepropylidene]ethane-1,2-diamine, has been synthesized and characterized by elemental analyses (CHN) and 1H-NMR spectroscopy. The crystal structure of 1 was determined using single-crystal X-ray diffraction. Structural investigation shows that 1 crystallizes in a monoclinic s...
متن کاملEnvironmental contamination of mercury from Hg-mining areas in Wuchuan, northeastern Guizhou, China.
Total Hg and methyl-Hg were evaluated in mine wastes, soils, water, and vegetations from the Wuchuan Hg-mining areas, Guizhou, China. Mine wastes contain high total Hg concentrations, ranging from 79 to 710 microg g(-1), and methyl-Hg from 0.32 to 3.9 ng g(-1). Total Hg in soil samples range from 0.33 to 320 microg g(-1) and methyl-Hg from 0.69 to 20 ng g(-1). Vegetations present a high average...
