Most chemical engineers and chemists are aware of the recent excitement generated by nanotechnology, but many may wonder what all the fuss is about. Nanotechnology deals with small, nanometer-scale objects, which chemical engineers and chemists deal with everyday, at least in the form of atoms and molecules. Even so, those who realize that there is some distinction are often a little unsure of the "nuts and bolts" involved.... http://www.che.com/processing_and_handling/nanotechnology/Cover-Story-Nano-Know-How_4496.html
A new pilot reactor — claimed to be the world’s first, complete two-step supersonic reactor — for producing nanoparticles has started operation at the Technology Service Center of the Wolfgang Industrial Park (IPW) GmbH, a subsidiary of Evonik Industries AG (Essen, Germany; www.evonik.com). Designed by Evonik’s Process Technology & Engineering Service Unit, in collaboration with seven universities and the German Aerospace Center (DLR; Cologne, Germany), the reactor uses supersonic flow to generate particles in the gas phase.... http://www.che.com/processing_and_handling/nanotechnology/Chementator-Making-nanoparticles-at-Mach-2-6_4330.html
