*”Hadad leads an effort to model the chemical structure of candidate enzymes on the powerful parallel supercomputer systems at OSC, while Magliery is producing synthetic versions of the new enzymes for further testing and preclinical evaluation by the Army.” *”The preliminary results from the fir...
," she said. "The surfaces of clay minerals, which only contain oxidized iron, are not reactive. They adsorb arsenic, but don't transform it chemically. However, these same surfaces become reactive as soon as a minor amount of reduced iron is introduced into the clay mineral's structure."...
Despite the general trend of qualitative changes in the bacterial community, it was found that the differences in the chemical structure of the AgNP stabilizing layers had a significant impact on the specific metabolic activity resulting from qualitative changes in the microbiome. Keywords: silver ...

their 3D structure. Accordingly, results of many researches on different hydrogels used to remove metal ions were reviewed. To understand the adsorption process and optimize the environmental conditions at the maximum adsorption, effective parameters such as pH, initial metal concentration, contact time,...
Arsenic is one of the most important contributors to non-car TE risk in hospitals in Portugal (Slezakova et al., 2014). The high non-car risk of Mn cannot be ignored. Because of its high solubility, Mn can cause toxic effects on multiple organs and the cardiovascular, reproductive, ...
