Yeah, I guess I should have been a little more clear in my statement: Maybe.."If you are buying a nanofluid for thermal enhancement, and it is clear, and cheap, it is a bunch of crap"..that a little more clear? Is anyone even using SiO2 for thermal management? How much is it? Gold/Ti?Carbon nanotubes/Diamonds were way out of our price range..Thus, the CHEAP part in the statement above. Shoot, I bet your DI water has a few nanoparticles in it, and it is probably clear. I looked around and didnt see any gold nanofluids or silver nanofluids or Ti nanofluids or diamond nanofluids that I could buy for thermal management..where did you get yours?
Yeah, we know all about shape control..we do that as best we can. That is sort of limited by science and the actual manufacturing of the nanoparticle. We looked at all kinds of nanoparticles/sizes/concentrations. Nice things about ZnO is that it is a biocide and doesn't react with copper or aluminum. And, it is white because Zinc-Oxide is white, but your physics is close to right..if Zinc-oxide were blue it would be blue..
Still, we can do a comparison with your 30% by weight Si02 and our stuff to see which one works better..better yet, you can pick any transparent nanofluid and compare it with ours (We will define the transparency as our PIV system being to function. LaVision is where we got our system from. We can do a full comparison..looks at pump power, pump wear and tear, wear on the block, over all cost of the fluid, plus any upkeep of the loop needed..whenever you are ready.
