Phytoremediation capability of Anabaena sp. for high organic and chromium-loaded wastewater in membrane bioreactors.

The efficiency of Anabaena sp. was analyzed for the phytoremediation of wastewater loaded with organic matter and heavy metals like chromium. Simulated wastewater was contaminated with chromium.

Air and Moisture Stable - and -Quinodimethane Derivatives Derived from --Heterocyclic Olefins.

Herein we report the development of a new methodology for the synthesis of various quinodimethane derivatives under two-electron oxidation of --heterocyclic olefins linked by different π-conjugated aromatic spacers. In case of - and -phenylene bridge, we obtained air and moisture stable diimidazolium - and -quinodimethane derivatives. Analogues of the -phenylene spacer such as tetrafluoro--phenylene and -anthracene also led to the corresponding air and moisture stable quinodimethane derivatives.
