ChemPlusChem 2/2015: Special Issue
The contributions in this special issue of ChemPlusChem focus on metal--air batteries and redox flow batteries. Our guest editors Jaephil Cho, Linda Nazar, and Peter Bruce have ensured that a broad range of papers on cutting-edge research are presented in addition to two Reviews and three Minireviews. In research on lithium--iodine batteries Hye Ryung Byon has developed high-performance aqueous cells in which a solid polymer electrolyte buffer layer serves to passivate the metallic lithium. In another paper of immediate relevance for the operation of vanadium redox flow batteries, Maria Skyllas-Kazacos and Ao Tang model the effect of the ambient temperature on residential-scale battery systems used for peak shifting. Finally, the concept of an "oxygen shuttle" for Li--air batteries is the focus of the article featured on the cover of this issue by Tatsumi Ishihara. More information on this research is given in the cover profile.

Nose to the grindstone: 1D double-zigzag and 2D polyrotaxane frameworks of ZnII-papx solids (x=so, sc, oc, soc) can be interconverted by heating and grinding in the presence of moisture. This structural transformation has been proven experimentally by powder and single-crystal X-ray diffraction studies.

Unwanted ion adsorption: Ultrathin, hydrogel-like antifouling surface chemistry on glass, which features monoethylene glycol based molecular residues, markedly reduces the rate of fluoride depletion from aqueous solution. At room temperature, anion adsorption until surface saturation is delayed by several hours.
- Biosynthetic Studies of the Male Marking Pheromone in Bumblebees by Using Labelled Fatty Acids and Two-Dimensional Gas Chromatography with Mass Detection
Dr. Petr Žáček, Dr. Jiří Kindl, Dr. Kateřina Frišonsová, Markéta Průchová, Dr. Alena Votavová, Dr. Oldřich Hovorka, Dr. Tomáš Kovalczuk and Dr. Irena Valterová
Article first published online: 26 FEB 2015 | DOI: 10.1002/cplu.201402420
The birds and the bees: The biosynthesis of marking/sex pheromones in male bumblebees (Bombus lucorum, B. lapidarius, and B. terrestris) was studied. In vivo application experiments of isotopically labelled fatty acids and subsequent analysis of the metabolites revealed that aliphatic pheromonal components can be synthesized from fatty acids stored in the fat body.
- Synthesis and Composition-Dependent Visible Photocatalysis of Ag/AgBr Necklace-Like Heterostructures
Xiaoyu Li, Xiao Zhang, Dr. Changchao Jia, Katarzyna Matras-Postolek and Prof. Ping Yang
Article first published online: 23 FEB 2015 | DOI: 10.1002/cplu.201500032
Functional necklace: A two-step synthesis was developed to fabricate Ag/AgBr necklace-like nano-heterostructures. The material with 40 mol % AgBr displayed a regular necklace-like morphology and samples with 10 to 50 mol % AgBr exhibited enhanced plasmonic photocatalytic performance for the degradation of organic pollutants (methyl orange, methylene blue, and rhodamine B) under visible light.
- Highly Selective Continuous-Flow Synthesis of Potentially Bioactive Deuterated Chalcone Derivatives
Chi-Ting Hsieh, Dr. Sándor B. Ötvös, Prof. Dr. Yang-Chang Wu, Dr. István M. Mándity, Prof. Dr. Fang-Rong Chang and Prof. Dr. Ferenc Fülöp
Article first published online: 23 FEB 2015 | DOI: 10.1002/cplu.201402426
Avoiding over-reaction: Various dideuterochalcones have been synthesized selectively by means of the highly controlled partial deuteration of antidiabetic chalcone derivatives. The benefits of continuous-flow processing were exploited in combination with on-demand electrolytic generation of D2 gas (see figure) to avoid over-reaction to undesired side products and to achieve selective deuterium incorporation without the need for special reagents.
