Is there an estimate of the maximum fullerene concentrations achievable for these three systems?

The concentrations of the systems studied were 2.5 mg/ml for arginine, 2.33 mg/ml for lysine, and 2.36 mg/ml for piperazine.

~10 mg/ml of C60 is a kind of limit for the ultrafiltration method used here. Further increases in concentration will be the subject of research in the nearest future.

Thank you!

Thank you for curious poster!  

I have a number of questions about it:
1) What is p(r)norm function at the third slide with SAXS and which model I(q) did you use for the curves fitting? 

2)  Did you investigate the fresh solutions of C-60 or you kept it for some time (about a day or smth like that) before analysis?

Thank you!

[Alina Tomchuk]

For data treatment, the procedure of indirect Fourier transform was used, as a result of which the pair distance distribution functions, p(r), were obtained. Solid lines are corresponding spline fit.
These systems are quite stable. Experiments on neutron scattering and DLS were carried out in the period from one to eight months after preparation, the results were repeatable.

Best regards, Alina
