Hi all,
I am looking for a software the can calculate molecular surface as well as properties over that surface (such as hydrophobicity, electron density, electric potential, etc.).

Thanks ahead!

Hi Shirel, welcome!

And you hope that the output of such a software would make any sense?

To the very least, it would need an extremely accurate description of what a given surface comprises. Just a few molecular layers change completely these properties, and these adsorbed molecules are usually unknown, even in microelectronics with extreme cleanliness and control.

When cleaning silicon (during the paleomonolithic era), a simple visual test was hydrophobicity. Describing the surface as "silicon" wouldn't have sufficed, since it was still "silicon" after cleaning, but had become hydrophobic.

Except in the best technological vacuum, a surface gets contaminated within microseconds, and by unknown compounds. Are you limiting the predictions to perfect vacuum only?
