Marten, You might want to google or bing "nickel nanowire grow" or "nickel whisker grow".
Some of these techiques are hazardous, so better use extreme caution. My guess is that (poly-)crystalline nanostructures are most promising. > Hello guys > I have a q, i have been reading all the posts about the problems with > energy transfer, core melts and so on . > Why not embed the nickel / catalyst mix in a honeycomb, or other > structure that gets easy acess for both H2 and > heat trasnfer to the walls of the tube ? > > Is there any practical method of doing this? > I have thought about covering steel or other material with nickel as so > many other people, but in my mind that decrease the surface > too much, a fungi or honeycomb like structure would maybe work, but how > to make one ? > > Any ideas ? > > > Marten > > >
