Jason Graetz, left, and Jiajun Chen at NSLS beamline X14A with their transparent reactor for viewing chemistry in real time. Here's a recipe for basic chemistry: Mix a bunch of stuff in a reaction vessel and see what happens. Only you don't really see the action taking place -- unless you have some way to visualize the molecular magic. Researchers at Brookhaven National Laboratory have developed just such a technique: They've fabricated a transparent chemical reactor vessel that allows x-rays to pass through and capture the chemical changes as they take place. They recently used this…
