A chemical microreactor with a high aspect ratio. In one embodiment the chemical microreactor has a chemical microreactor section with channels having a height and with spacings having a width. There is a high aspect ratio of the height to the width. The high aspect ratio in one embodiment is more than substantially 5:1. The high aspect ratio in another embodiment is more than substantially 10:1. The high aspect ratio another embodiment is more than substantially 15:1. The high aspect ratio in one embodiment is substantially 20:1.

In one embodiment the catalyst coating the microchannels comprises a nanostructured material. In another embodiment the catalyst coating the microchannels comprises an aerogel. In another embodiment the catalyst coating the microchannels comprises a solgel. In another embodiment the catalyst coating the microchannels comprises carbon nanotubes.
摘要:
An automated process that can produce targets of any density gradient along an axial and a radial coordinate is explored. Such an approach is based on the observation that particles of different size, shape and density settle in fluid-filled columns differently. The invention presents models and procedures to automate the process so as to obtain any combination of density gradients.
