About the Research Going on in the Field of Nano Fluids

That's not my field, but some quick searches might yield some useful information.

It is a rather new, unknown field.

Heat transfer enhancement of nanofluids - ScienceDirect.com

Heat Transfer Intensification Using Nanofluids - IDC Technologies

Mechanisms of Enhanced Heat Transfer in Nanofluids - FNOES

Maybe contacting some universities that are doing research in the field.

Good luck!

Newsletters from these two sources do not deal exclusively with nanofluids, but they give you lots of material. You can pick and choose at your pleasure.

In matters of online research, Google is your friend. Good luck!

What is a "nano fluid"? The concept of nano solids is understandable, but aren't all fluids inherently nano?

Nanu Nanu.

A suspension consisting of nanophase powders and a base liquid.

I'm from the ferrofluid era. A sort of fluidic dinosaur.

Oh, upscale slurry.
