NASA, Purdue study offers recipe for global warming-free industrial materials http://apocadocs.com/s.pl?1272974517
Let a bunch of fluorine atoms get together in the molecules of a chemical compound, and they're like a heavy metal band at a chamber music festival. They tend to dominate the proceedings and not always for the better.
That's particularly true where the global warming potential of the chemicals is concerned, says a new study by NASA and Purdue University researchers.
The study offers at least a partial recipe that industrial chemists could use in developing alternatives with less global warming potential than materials commonly used today.... "What we're hoping is that these additional requirements for minimizing global warming will be used by industry as design constraints for making materials that have, perhaps, the most green chemistry," says Joseph Francisco, a Purdue chemistry and earth and atmospheric sciences professor. The classes of chemicals examined in the study are widely used in air conditioning and the manufacturing of electronics, appliances and carpets. Other uses range from applications as a blood substitute to tracking leaks in natural gas lines....
