8_05/2015Cover Picture: Electrifying White Biotechnology: Engineering and Economic Potential of Electricity-Driven Bio-Production (ChemSusChem 5/2015)

The Front Cover picture, drawn by co-author Frauke Kracke, was inspired by the concept of using electric energy and biomass for the production of fuels and chemicals. It depicts our present society based on fossil fuels, e.g., oil, which are converted into fuels and chemicals in chemical refineries, and a future greener world in which biomass is converted in electro-bioreactors using energy from renewable sources. The Concept article discusses current benefits and limitations of the technology and its potential to contribute to a more sustainable world. The article shows, for the first time, by the example of an established fermentation process, that there can be realistic economic incentives for using microbial electrochemical technologies for bio-production. However, it also addresses the many hurdles to be overcome before the depicted “green world” can become reality. More details can be found in the Concept by Harnisch et al. on page 758 (DOI: 10.1002/cssc.201402736).

8_05i/2015Inside Cover: Functionalized Fe3O4@Silica Core–Shell Nanoparticles as Microalgae Harvester and Catalyst for Biodiesel Production (ChemSusChem 5/2015)

The Inside Cover illustrates how a Fe3O4@silica core–shell magnetic nanoparticles functionalized with a strong base [i.e., triazabicyclodecene (TBD)] can be used for sequential microalgae harvesting and for the one-pot conversion of microalgae to fatty acid methyl ester (biodiesel). While being effective for transforming algae oil of multiple algae sources, its excellent adsorption and magnetic properties make TBD-Fe3O4@silica nanoparticles exceptionally suitable for algae harvesting. A wide range of other covalently functionalized nanoparticles can be envisaged to be applied for the production of liquid transportation fuels from algal biomass. More details can be found in the Communication by Wu et al. on page 789 (DOI: 10.1002/cssc.201402996).

8_05c/2015Inside Back Cover: Rhenium-Catalyzed Deoxydehydration of Diols and Polyols (ChemSusChem 5/2015)

The Inside Back Cover shows a van Krevelen diagram where it is clear that the deoxydehydration reaction (DODH, green arrows) furnishes a dramatic change in the H/C and O/C ratio for various biomass constituents. It is compared to dehydration (blue arrows) and reduction (red arrows). Although the DODH reaction is formally the sum of a reduction and a dehydration, the use of a one-step transformation can be advantageous, for example in the direct conversion of glycerol to allyl alcohol. The DODH reaction is discussed in the Minireview by Dethlefsen and Fristrup on page 767 (DOI: 10.1002/cssc.201402987).

8_05b/2015Back Cover: Bifunctional Silver(I) Complex-Catalyzed CO2 Conversion at Ambient Conditions: Synthesis of α-Methylene Cyclic Carbonates and Derivatives (ChemSusChem 5/2015)

The Back Cover image shows utilization of CO2, which holds great promise as a sustainable feedstock rather than a waste. The idea of the whole image comes from an ancient Chinese Taiji (Taoism) nose map: on the one hand, CO2 is an exhaust gas and a greenhouse gas; on the other hand, it can be upgraded into numerous fruits through an ingenious methodology, namely catalysis, which can be considered as a great contribution towards realizing a beautiful world and better life. Incorporation of CO2 into chemicals can be achieved through a catalytic pathway at ambient conditions. This metal-promoted protocol can be applied to various transformations of CO2 into value-added products on a 10 g scale. The synergic activation mode based on the bifunctional silver(I) catalyst used is supported by DFT studies, NMR spectroscopy, 13C labelling, and control experiments. More details can be found in the Full Paper by Song et al. on page 821 (DOI: 10.1002/cssc.201402921).
