The front cover artwork for issue 12/2013 is provided by the group of Prof. Zhonghua Zhu, in collaboration with Prof. Sean C. Smith of Oak Ridge National Laboratory, and Prof. Aijun Du from Queensland University of Technology. The image shows how carbon nanotubes and/or graphene with doped pyridinic nitrogen could be applied for controllable, highly selective, and reversible CO2 capture.

What is the most significant result of this study?
12Pyridinic nitrogen on carbon nanotubes (CNT) is found to increase the CO2 adsorption strength in the presence of injected electrons, leading to a highly selective adsorption of CO2 over N2. This functionality can induce intrinsically reversible CO2 adsorption by switching the charge carrying state of the system on/off.
What inspired you for the cover image?
The inspiration is the study presented in this paper itself. The image shows the main source of accumulating CO2 in atmosphere, our solution, and the outlook of the solution, arranged along a diagonal from lower left to upper right. The models investigated within this paper are arranged along the diagonal from upper left to lower right.
What future opportunities do you see?
The future opportunity raised by this work is that fully metal-free, carbon based materials could be applied for efficient CO2 separation and clean energy storage/conversion.
