howdy, just wondering if anyone had some keen insight. should there be a way in which i can predict the shapes of growing fcc metal nanocrystals based simply on things like the metal precursor, the reducing agent, the "capping agent" etc. (iow, the reaction conditions) i mean, would i have to go all out and do ab initio or semi-empirical calculations? or is there some back-of-the-envelope method that i am missing? i've found it's fairly easy to "predict" what shape crystals might become in a high vacuum using older theories like Wulff, etc. but those don't hold up well with nanocrystals in a condensed phase, is there some old theory that i'm missing?
