The cover image depicts a cellulose based superabsorbent hydrogel produced through environmentally sustainable processes.  A heterogeneous TiO2 photo-catalysed process has been proposed for the detoxification (and a possible re-use) of washing waste waters produced from the hydrogel preparation.  Image reproduced by permission of Alessandro Sannino.

The cover illustrates the use of the same continuous reactor for either hydrogenation or oxidation in high pressure high temperature water, merely by changing the precursor for the reacting gas.  In the background are the Tis Abay (Blue Nile Falls), Ethiopia.  Image reproduced by permission of Martyn Poliakoff.

The cover image illustrates how pure products can be removed from ionic liquids either by extraction with carbon dioxide as co-solvent, or by precipitation using carbon dioxide as anti-solvent.  Image reproduced by permission of Maaike Kroon.
