Is there any way to correlate microhardness, youngs modulus and ultimate tensile strength for aluminum?

It would be interesting if Young's modulus and UTS correlated at a certain point. Then, the relationship could be proved with other essential characterisations without breaking the samples.

If you are using Pristine CNTs, 'Alkyl benzene ethoxylates' (low HLB) type of surfactants will work good. Polar functionalization on CNT will obviosly facilitate the process.

Thank you vishal,,,,,can you give a bit more details about natural surfactants??

The non-ionic surfactants which I used are purely/ semi- synthetic. You can use Stearic & Oleic (i.e. fatty acid) derivatives such as esters, sulfonates, ethoxylates etc., but all these are semi-synthetic..
