The more complete list of review papers (38 !) about structure
determination by powder diffractometry is available at :

Other goodies including details on 350 experimental cases
searchable by keywords (that will show you if GSAS is
sufficient or not), a tutorial, (...), are gathered at :

Nanocrystalline means large FWHMs and difficulties if
the structure is complex. Obtaining a better crystallinity, if
possible, would be the first step.
