Not only chemical composition, but also texture, determine the degree of resistance to all these factors. The qualities of metals required for chemical purposes may be improved by (a) the elimination of impurities, (6) adding other metals in such quantities as to produce substantially new alloys...
In the case of metals, this is referred to as corrosion. In the case of polymers and ceramics, it is degradation. In all cases, there is a chemical reaction between the components in the environment, especially oxygen and the solid material. From the design point of view, environment sets...

The impact of chemicals on the environment and human health is a cause of increasing concern. Although many studies continue to be carried out on this subject, most address only individual chemicals or particular groups of chemicals, such as metals or radioactive substances. In this paper, we ...
dean of Institute for frontier technologies of low-carbon steelmaking of Northeastern University of China. He is serving as deputy secretary general of the Metallurgical Reaction Engineering Branch and member of the Metallurgical Solid Waste Resource Utilization Branch of the Chinese Society of Metals. ...
This raises the question as to why the metals would be remobilized at the post-subduction stage rather than by previous arc magmas. Nevertheless, the style and mechanism of Cu distribution and migration in the lower crust remain unclear due to the lack of direct studies on lower crustal rocks...
CHEMISTRYoftheENVIRONMENT环境化学讲义.ppt,Most municipalities also carry out secondary treatment, which harnesses(利用) bacteria to metabolize organic compounds, converting them to CO2. In this way, the BOD is substantially decreased (see Figure 14.6). I
Magmatism therein was dominated by the production of A-type granites, including granodiorite and monzonitic granite intrusions, as well as contemporaneous volcanism that formed rhyolite and tuff units, all of which formed in an extensional environment (Sun et al., 2007; Li et al., 2014; Liu ...
The interaction between the filler and the lithium salt. This involves the alteration of the lithium-ion chemical environment. And reflected mostly in the changes in ionic conductivity and tLi+. (2) The interaction between the filler and the polymer. This involves changes in the polymer aggregate...
