Ion-containing polymers: new energy & clean water

Providing clean water, keeping water clean: an integrated approach.

Millions of people, most of whom are children in developing countries, die of basic hygiene-related diseases every year. Interventions in hygiene, sanitation and water supply have been shown to control disease burden. Universal access to improved water sources and basic sanitation remains elusive but is an important long-term goal. Studies have shown that improving the microbiological quality o...

Morphology of Ion-Containing Polymers: Correlations Between Structure, Dynamics, and Ion Conduction

Ion-containing polymers are of intense interest for applications in energy storage and conversion devices. The conductivities of these polymers are determined by both the ion mobility and the total number of mobile charge carriers, which in turn depend on the chemical structure and morphology. To rationally design ioncontaining polymers with high conductivity, a comprehensive understanding of t...

Clean Water Act

Definition The US Congress enacted the Clean Water Act in 1972 (P.L. 92-500, the 1972 Amendments to the Federal Water Pollution Control Act), which is the principal law dealing with polluting activity in streams, rivers, lakes, and estuaries of the USA (Copeland, 2006). The Clean Water Act established a water quality standards approach for regulating water quality, with the US Environmental Pro...

New Thermal and Microbial Resistant Metal-Containing Epoxy Polymers

A series of metal-containing epoxy polymers have been synthesized by the condensation of epichlorohydrin (1-chloro-2,3-epoxy propane) with Schiff base metal complexes in alkaline medium. Schiff base was initially prepared by the reaction of 2,6 dihydroxy 1-napthaldehyde and o-phenylenediamine in 1 : 2 molar ratio and then with metal acetate. All the synthesized compounds were characterized by e...
