A few articles from this week's issue of C&EN:
- Cover: Virtuous materials cycles (by Melody M. Bomgardner)
- This Mitch Jacoby piece on liquid metals (specifically gallium alloys) is really cool.
- The U.S. Geological Survey had a rogue chemist with an ICP-MS? (article by Jessica Morrison)
- Unexpectedly fascinating article by Alex Tullo on the decline of cellulose acetate sales due to declining cigarette sales.
- Methane and sulfur trioxide to make methanesulfonic acid? (article by Michael McCoy)
gallium-based flexible circuits would be probably not allowed on the planes. Also, the assertion that methanesulfonic acid is a nontoxic biodegradable noncorrosive alternative to sulfuric acid is a ridiculous sales pitch. (If you work in process group, one thing to watch out for is mixing MsOH with methanol, methyl methanesulfonate forms readily and is pretty genotoxic. The advantages of MsOh over sulfuric acid is that it does not have oxidative properties and does not sulfonate, and the molarity is lower - if you are using it as a reaction medium and need to quench and neutralize the whole damned reaction mix.)
