No,Nanoparticles are in pure state and they want to absorb asphaltene dissolved in toluene. I want to have data on molar volume and surface tension of nanoparticles in pure state (i.e. before absorption)

Hi .how can i calculate the molar volume and surface tension of nanoparticles ? shoud i have to calculate? or these parameters is available in tables or sth?

Yes, but i couldn't found it .

Hi , this is my equation : μA= μA0 + RTlnaA A is the asphaltene in toluene solution . i want to calculate μA in different temperatures. where can i get μA0 and aA? tables? other equations? μA0 is the standard chemical potential of asphaltene and aA is the asphaltene activity in solution.

I think yes, solution is ideal. if its ideal,what is the fugacity of asphaltene in solution equal to? ( i mean which equation should I use? ), and why determining fugacity of asphaltene on nanoparticles is complicated?

Yes, for a better understanding, these images show what i need For the fugacity of asphaltenes in the solid and liquid phase, i don't know what equations of state can be used to include fugacity coefficients? after doing this, i use the equation that encluding Z, instead of fugacity...

What do you mean by simply can not? what i have to do? Do you know what equations should I make instead of fugacity of asphaltenes on solid and in solution?

Hi guys I want to model the adsorption of asphaltenes on nanoparticles from a thermodynamic equilibrium solution ( this is my thesis ). from this way, I want to show how much asphaltene is adsorbed on nanoparticles at different temperatures and pressures (without using of isotherms of...
