I n this issue of PNAS, Schoonheydt, Solomon, and coworkers (1) definitively characterize the structure of the Cu-ZSM-5 site that oxidizes methane to methanol. With the successful correlation of a specific copper-oxy structure to such reactivity, the importance of this work extends beyond hydrocarbon oxidation on zeolites. This breakthrough potentially has farreaching implications in both the f...

 The aquatic fern Azolla, a small-leaf floating plant that lives in symbiosis with a nitrogen fixing cyanobacteria (Anabaena), is an outstanding plant, thanks to its high biomass productivity along with its tremendous rate per unit area for nitrogen-fixation.  The present study investigates the potential growth of Azolla in secondary effluents for removal of COD, phosphorus, and nitrogen. Resul...

La4Cu3MoO12 is a new (ABO3)n)4 cuprate with mixed B-cations in a ratio of 1:3. When synthesized at ambient pressure, the structure is not perovskite as expected but rather a homeotype of YAlO3, a rare-earth hexagonal phase. While the P63/mmc and Pmnm space groups can be used to model average structures which appear in quenched samples; powder, electron, and neutron diffraction data all confirm ...

The mixed-metal title compound, BaCu1/3Ta2/3S3 [barium copper(II) tantalum(V) tris-ulfide], was prepared through solid-state reactions. The crystal structure adopts the BaTaS3 structure type and consists of face-sharing [MS6] (M = Ta,Cu) octa-hedra (point-group symmetry -3m.) that are condensed into infinite chains along [001]. Adjacent chains are linked through the barium cations (site symmetr...
