7_12/2014Cover Picture: Integrated, Cascading Enzyme-/Chemocatalytic Cellulose Conversion using Catalysts based on Mesoporous Silica Nanoparticles (ChemSusChem 12/2014)

The Front Cover image depicts a unique cellulose deconstruction strategy developed by Kevin Wu and co-workers. Enzymatic cellulose deconstruction is achieved by using hydrolase enzymes hosted by mesoporous silica. Abundant sources of cellulose in Taiwan can be explored by using hydrolase enzyme immobilized on magnetic mesoporous silica nanoparticles. This strategy is capable of deconstructing cellulose to produce a versatile platform chemical that, through upgrading to liquid fuels and chemicals, is capable of fuelling the globe like the sun. How an integrated enzyme cascading chemocatalytic strategy can be used for a formidable cellulose deconstruction is one of the most interesting findings revealed. More details can be found in the Communication by Lee et al. on page 3241 (DOI: 10.1002/cssc.201402605), while more information about the research group is available in the Cover Profile (DOI: 10.1002/cssc.201402973).

7_12i/2014Inside Cover: Directed Synthesis of Nanoporous Carbons from Task-Specific Ionic Liquid Precursors for the Adsorption of CO2 (ChemSusChem 12/2014)

The Inside Cover illustrates a series of task-specific ionic liquids used to synthesize porous carbon materials that are suitable for the post-combustion CO2 capture. The pore architecture and surface properties of the carbon adsorbent can be tailored by varying the structure of the ionic liquid precursor. As the linker in the bisimidazolium cation is varied, the porosity of the resulting carbon can be modified from purely microporous to hierarchical. The composition of the ionic liquid also generates porous carbon with nitrogen-containing functional groups for enhanced CO2 adsorption. More details can be found in the Full Paper by Mahurin et al. on page 3284 (DOI: 10.1002/cssc.201402338).

7_12c/2014Inside Back Cover: Photoactive Nanocrystals by Low-Temperature Welding of Copper Sulfide Nanoparticles and Indium Sulfide Nanosheets (ChemSusChem 12/2014)

The Inside Back cover illustrates the coalescence of binary chalcogenide nanoparticles to photoactive ternary nanocrystals. When oppositely charged nanocrystals are mixed in room temperature, they coalesce to the final product by simple stirring. The coalescence of polycation-coated CuS nanoparticles and negatively charged In2S3 nanoplates to CuIn5S8 nanocrystals are driven by close contact of the particles due to electrostatic interactions. A photovoltaic device utilizing coalesced particles yields a power conversion efficiency of 1.9 %.

7_12b/2014Back Cover: Nanorod and Nanoparticle Shells in Concentration Gradient Core–Shell Lithium Oxides for Rechargeable Lithium Batteries (ChemSusChem 12/2014)

The Back Cover image highlights the use of nanorods in the development of an innovative battery. These nanorods have a concentration gradient in its core–shell structure, which facilitates the transport of lithium ions and electrons and thus increases the resulting electrical conductivity. In addition, densely agglomerated nanorods in the shell region give rise to a high tap density with a reduced pore volume and surface area, which result in the outstanding electrochemical properties and high rate performance. Using the unique structure of these nanorods, we can move one step closer to the commercialization of lithium ion batteries with the large energy storage capacity and the safety required to power electric vehicles. More details can be found in the Full Paper by Yoon et al. on page 3295 (DOI: 10.1002/cssc.201402389).
