October 2009: US-China Workshop on Supramolecular Chemistry for Early Career Scientists

A successful meeting of 12 US and 12 Chinese supramolecular chemists at early stages in their careers was held in Beijing. The meeting was sponsored by the respective chemical societies (ACS and CCS) and the national science foundations (NSF and NSFC).
