ChemPlusChem 6/2015: Highly Important Paper
Articles that reviewers rate in the top 20% in terms of importance deserve special attention. We are pleased to highlight a paper of this caliber in Issue 6: Mohammad Gholinejad et al. describe a novel heterogeneous catalystconsisting of CuFe2O3 and Pd0 nanoparticles assembled on silica microparticles (see picture). This catalyst effects the Sonogashira coupling reaction of aryl iodides and bromides with various alkynes, a reaction that typically requires both palladium and copper cocatalysts, neither of which are readily recovered. The added extra of the new catalyst is that it can be recovered easily with a magnet, then rinsed, dried, and reused.

Focus on anodes: The application of microbial fuel cells for wastewater treatment has emerged as a green energy technology. In recent work leading to microbial fuel cells with enhanced performance, the anode has been manipulated to improved its biocompatibility, provide sufficient space for bacteria, and facilitate electron transfer.
- “On–Off” RGD Signaling Using Azobenzene Photoswitch-Modified Surfaces
Dr. Elisa Vaselli, Chiara Fedele, Dr. Silvia Cavalli and Prof. Dr. Paolo A. Netti
Article first published online: 1 JUL 2015 | DOI: 10.1002/cplu.201500179
Let there be light: Switchable light-responsive surfaces were developed by coupling the GRGDS peptide sequence to an azobenzene unit and then clicked to silanized glass substrates (see figure). The “on–off” reversible switch was monitored by contact angle techniques and photocontrolled cell adhesion was tested with human umbilical vein endothelial cells (HUVECs).

Cu2MnSnS4 nanosheets oriented parallel to the (002) crystal plane have been synthesized through a simple solution method. The Cu2MnSnS4 nanosheets show enhanced conductivity under light irradiation, disclosing their suitability for photovoltaic applications (see figure). Weakly ferromagnetic behavior at low temperatures was found for the Cu2MnSnS4 nanosheets.
