Specific surface area

Nano technology demystified is for anyone interested in the nanoscale world who wants to learn more about this exciting new area. It can also be used by home-schooled students, tutored students, and those people wanting to change careers. The material is presented in an easy-to-follow way and can best be understood when read from beginning to end. However, if you want more information on specific topics—for example, quantum dots, nanoelectronics, lab-on-a-chip, and so on—or you want to check out only nanotechnology business happenings, those chapters can be reviewed individually.

Carbon aerogels prepared from resorcinol formaldehyde organic aerogels have a wide range of use due to their considerably large specific surface area. Since the applications mostly happen in wet form, e.g. in aqueous medium, NMR cryoporometry was employed to follow the porous behavior of an organic aerogel and its carbon derivative, as well as the textural changes after the pyrolysis.
