Mendeley Data - Consequences of trace metal cocktail …

Trace metal elements are significant stressors in urban areas. Their harmful effects on physiological parameters are demonstrated, but current laboratory studies are not representative of wild chronic exposure to a trace metal cocktail. Calcium can reduce the accumulation and toxicity of several metals, but soil acidifiion in cities leads to a decrease in bioavailability of this element

Two-way Valorization of Blast Furnace Slag: Synthesis of …

Since calcium acetate has an acetate-to-calcium ratio of 2:1, double the stoichiometric amount was used, as was found necessary by Chiang et al.5 In order to limit the presence of undesired impurities in the generated PCC, the leachate solution should be subjected to further purifiion before being carbonated; this is another novelty of the proposed syiotic process.

Effect of processing conditions on physical properties of …

The influence of processing conditions on the physical properties of transition metal-metalloid based metallic glasses was studied. It was shown that if the melt superheat and cooling rate are changed, the quenched-in stresses and the local environment of the constituent atoms are modified causing remarkable changes in several magnetic, mechanical and chemical properties. In addition, the

Why is calcium a metal? Why does it seem to have so …

Elemental calcium is indeed a metal, although a reactive one that tends to oxidize in air because of reaction with oxygen. The Ca 0 metal is not found often in nature for this reason. The "calcium" we talk about when we think of calcium scale on pluing is calcium carbonate , and other calcium salts.

Bromine - Wikipedia

Bromine is a chemical element with the syol Br and atomic nuer 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob
