Fluorido-bridged robust metal-organic frameworks for efficient CH/CO separation under moist conditions.

The modern technology for acetylene production is inevitably accompanied by the contamination of carbon dioxide and moisture impurities. Metal-organic frameworks (MOFs), with rational configurations of fluorine as the hydrogen-bonding acceptor (HBA), exhibit excellent affinities to capture acetylene from the gas mixtures. Currently, most research studies feature anionic fluorine groups as structural pillars (, SiF , TiF , NbOF ), whereas insertion of fluorine into metal clusters is rather challenging.

[Study on the public health emergent events in Fujian province in 2004--2007].

Objective: To study the public health emergent events (PHEE) in Fujian province, from 2004 to 2007.

Methods: Descriptive and analytic methods were used to analyze the PHEE in Fujian province according to the internet-based surveillance reports.

Results: From 2004 to 2007, there were 304 emergency events being surveyed.
