7_07/2014Cover Picture: Multifunctional Organized Mesoporous Tin Oxide Films Templated by Graft Copolymers for Dye-Sensitized Solar Cells (ChemSusChem 7/2014)

The Front Cover image illustrates the importance of organized mesoporous SnO2 film with high porosity, larger pores, and good interconnectivity in dye-sensitized solar-cells (DSSC) applications. Although SnO2 films have been studied to increase electron transport, a multifunctional SnO2 film with high porosity and an organized mesoporous structure has not yet been reported. The group of Prof. Jong Hak Kim prepared multi-functional organized mesoporous SnO2 (om-SnO2) film through a facile sol–gel process using a cheap graft copolymer as a structure-directing agent. The use of om-SnO2 film resulted in enhanced light harvesting, increased electron transport, reduced charge recombination, and decreased interfacial/internal resistance. More details can be found in the Full Paper on page 2037 (DOI: 10.1002/cssc.201301215), while more information about the research group is available in the Cover Profile (DOI: 10.1002/cssc.201400102).

7_07i/2014Inside Cover Picture: Chitosan-Microreactor: A Versatile Approach for Heterogeneous Organic Synthesis in Microfluidics (ChemSusChem 7/2014)

The Inside Cover picture shows a new technique developed by Prof. D.-P. Kim and co-workers to immobilize diverse metal/metal complex catalysts such as copper, gold, palladium, or ruthenium on chitosan as a common substrate in a solvent-resistant poly(dimethylsiloxane) microreactor for performing click chemistry, ester-assisted hydrations, and different coupling reactions. The channel surface grafted by chitosan biopolymer acted as a polymeric ligand owing to the presence of -OH and -NH2 groups. Up to 50 μg of the immobilized catalyst achieved turnover numbers on the order of 105 for organic transformations without the use of extra ligands and with no leaching; this is presumably attributable to highly dispersed chitosan nanobrushs present in the medium as well as the intrinsic characteristics of the microreactor. More details can be found in the Full Paper on page 1864 (DOI: 10.1002/cssc.201400012).

7_07b/2014Back Cover: Peapod-Like Composite with Nickel Phosphide Nanoparticles Encapsulated in Carbon Fibers as Enhanced Anode for Li-Ion Batteries (ChemSusChem 7/2014)

The Back Cover picture shows the unique evolution of the layered precursor of hydrated ammonia nickel phosphate nanorod to the peapod-like nanocomposite with nickel phosphide nanoparticles tightly encapsulated in carbon nanofibers. The transformation relies on glucose molecules as the carbon source and reductive reagent during the hydrothermal reaction and the high-temperature calcinations in inert atmosphere, respectively. The obtained peapod-like nanocomposite has prominent benefits for secondary Li storage, which can be attributed to the unique peapod nanostructure. The picture also shows the badge of Chongqing University in the center, which was founded in 1929 which has been substantially supported by the Chinese central government under the “985” and “211” educational schemes. More details can be found in the Full Paper by Wang et al. on page 2000 (DOI: 10.1002/cssc.201301394).
