What about adding nano technology?

Laura Pena seems to reduce friction by 60% adding specific nano particles in lubrication.

Dear Wederley,

Here are 4 references on the discussions about the validity of Reynolds and Generalized Reynolds equations for 3 types of lubricated contacts:

1) On pocket pad slider bearing:

Thank you very much, Michel! These papers will be very useful to my studies. I would like to comment that I already knew the second one from your list, and I found it a great paper, particularly in terms of its approach about the applications of Navier–Stokes and Reynolds equations for modelling the lubricant flow.

Best regards,
