The front cover artwork for Issue3/2014 is provided by the Inorganic Chemistry and Catalysis group of Utrecht University. The image shows the concept of synchrotron-based IR and UV/Vis microspectroscopy monitoring a catalytic reaction on a single SAPO-34 crystal and the obtained spatially resolved information on the retained hydrocarbon species and crystal accessibility. See the Full Paper itself on http://dx.doi.org/10.1002/cctc.201300962. "We consider the isotopic switching experiments combined with IR microspectroscopy the most novel aspects of this research." This and more about the story behind the research featured on the front cover can be found in this issue's Cover Profile.
