Green Chemistry issue 12 is now online! 

The front cover of this issue features work by Sibudjing Kawi and W. Thitsartarn from the National University of Singapore.  They report a stable and active CaO-CeO₂ catalyst, prepared by simple gel formation viaa co-precipitation method, which was applied to the transesterification of oil to biodiesel.  The catalyst could be reused up to 18 times without significant loss of activity and showed only low amounts of leaching.  Find out more by reading the full article ‘An active and stable CaO–CeO₂catalyst for transesterification of oil to biodiesel.’

The inside front cover highlights work from Jérôme Husson and co-workers from the Université de Franche-Comté.  They report a new synthesis route to 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine, a ligand that is a component of the “Black-dye” sensitizer for dye-sensitized solar cells.  The route developed by Husson has a lower ecological impact with respect to atom economy, yield, solvent and chemicals used and wastes generated, compared to the previously reported method.  Find out more by reading the full article ‘A more efficient synthesis of 4,4′,4′′-tricarboxy-2,2′:6′,2′′-terpyridine.’
