  • Characterizing the nature of heavy metal release reactions, sorption mechanisms, and movement in the soil is the main topic of this book. Because soils are heterogeneous, heavy metals in soils can be involved in a series of complex chemical and biological interactions including oxidation-reduction, precipitation and dissolution, volatilization, and surface and solution phase complexation. The heterogeneous nature of the different soil constituents adds to the complexity of interactions of heavy metal species with the soil environment....

  • The story of metal casting is as glamorous as it is ancient, beginning with the dawn of human civilization and interwoven with legends of fantastic weapons and exquisite artworks made of precious metals. It was and is involved in the two main activities of humans since they began walking the earth: producing and defending wealth. Civilization as we know it would not have been possible without metal casting. Metal casting must have emerged from the darkness of antiquity first as magic, later to evolve as an art, then as a technology, and finally as a complex, interdisciplinary science....

  • Metal foams are a new, as yet imperfectly characterized, class of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They offer potential for lightweight structures, for energy absorption, and for thermal management; and some of them, at least, are cheap. The current understanding of their production, properties and uses in assembled in this Design Guide.

  • Metal nanoparticles are certain to be the building blocks of the next generation of electronic, optoelectronic and chemical sensing devices. The physical limits imposed by top-down methods such as photo- and electron- beam lithography dictate that the synthesis and assembly of functional nanoscale materials will become the province of chemists.

  • Metals come from under the ground. Most metals are found in rocks, which are drilled out and crushed.The rocks are heated to make the metal melt. When the metal cools, it turns into a solid block.There are many different types of metal. Very strong metals are used to make bridges, boats and cranes.

  • The long-term effects of treatment with sirolimus-eluting stents, as compared with bare-metal stents, have not been established. Methods We performed an analysis of individual data on 4958 patients enrolled in 14 randomized trials comparing sirolimus-eluting stents with bare-metal stents (mean followup interval, 12.1 to 58.9 months). The primary end point was death from any cause. Other outcomes were stent thrombosis, the composite end point of death or myocardial infarction, and the composite of death, myocardial infarction, or reintervention....

  • Cadmium is a heavy metal and a pollutant that can be found in large quantities in the environment from industrial waste. Its toxicity for living organisms could arise from its ability to alter thiol-containing cellular com-ponents. Glutathione is an abundant tripeptide (c-Glu-Cys-Gly) that is described as the first line of defence against cadmium in many cell types.
