Engineers at Oregon State University have discovered a new method of producing nanoparticles that is said to be 500 times faster than existing production methods. The approach uses an arrayed microchannel reactor and a laminated architecture in which many sheets, each with thousands of microchannels in them, are stacked in parallel ...
