What comes to mind when you think of a chemistry lab? Maybe it’s smoke billowing out of glassware, or colorful test tubes, or vats of toxic substances. Chemistry and hazardous solvents just seem to go hand in hand. But chemists like James Mack think there’s a greener way: It’s called mechanochemistry, a kind of chemistry that uses physical force to grind materials instead of solvents. And it’s getting the attention of such huge corporations as Exxon Mobil. Still, some chemists are not ready to give up their traditional techniques. “I thought they were married to the molecules,” says Mack, who is pictured above placing vials into a machine that uses fast-spinning ball bearings to pulverize molecules. “Little did I know they were actually married to the flask.”
