The biggest such particle as defined in by Rossi's patent is 100 microns. The smallest is 1 micron.
Could You once do a proper calculation for e.g. a nanoparticle of 10nm?? (surface app. 2 x 10 x10 nm)
And then please explain us how you would find billions of nano-pores which certainly must be bigger than a single atom missing!
Thanks!
