Sediments are considered the sink for metals in aquatic environments because of their strong metal-binding capacity, but they are a potential source for metal ingestion by marine benthic animals as well. Sediment contamination is now a major environmental problem in many countries, including China. This study examines the bioavailability to a marine suspension-feeder (the clam Mactra veneriform...
We present data of the time-evolution of a remediation approach on a marine shore tailings deposit by the implementation of an artificial wetland. Two remediation cells were constructed: one in the northern area at sea-level and one in the central delta area (above sea-level) of the tailings. At the beginning, the “sea-level” remediation cell had a low pH (3.1), with high concentrations of diss...
Chronopotent iometry of chromate in the presence of NiC12 in molten LiCIKCI eutectic reveals a diffusion controlled, three electron reduct ion step. In the presence of excess NiC12, chromate is reduced at --0.35V vs. P t ( I I ) / P t reference electrode and the electroactive species responsible for the chronopotentiometric wave is estimated to have a diffusion coefficient of 1.06 9 10 -5 cm 2 ...
Sputtered-deposited Zn(O,S) is an attractive alternative to CdS for Cu(In, Ga)Se 2 (CIGS) thin-film solar cells' buffer layer. It has a higher band gap and thus allows greater blue photon collection to achieve higher photon current. The primary goal of the thesis is to investigate the effects of the secondary barrier at the buffer-absorber interface on the distortions to current-voltage (J-V) c...
This note is a reply to the « Comment on The Cu-Pb-Zn-bearing veins of Bou Skour deposit (Eastern Anti-Atlas, Morocco): structural control and tectonic evolution » by Hmidou El Ouardi et al., published in Comptes Rendus Géoscience Volume 354, 2022, pages 119–123 (https://doi.org/10.5802/crgeos.115). It concerns article Aabi online May 04, 2021, Geoscience 353, 81–99 (https://doi.org/10.5802/crg...
Angouran zinc and lead deposit is located about 135 km west of Zanjan city, in the northwest of the Sanandaj-Sirjan structural zone The results of this study indicate that the dolomitic alteration occurred in the carbonate hanging-wall and the presence of ankerite in the schist footwall. The main host of ore deposit is metamorphic carbonate. The Angouran dolomite is secondary and hydrothermal. ...
