European Journal of Inorganic Chemistry 19/2013 19/2013 EurJIC 1st July Issue European Journal of Inorganic Chemistry Cover Picture Emmanuel Terazzi, Claude Piguet et al. Single-Stranded Dinuclear Lanthanide Helicates A Journal of www.eurjic.org EJICFK (19) 3271–3440 (2013) · ISSN 1099-0682 · No. 19/2013 CONTENTS Hungary Italy Germany Greece EurJIC is a journal of ChemPubSoc Europe, a union of 16 European chemical societies formed for the pur- pose of publishing high-quality Czech Republic France science. All owners merged their national journals to form two leading chemistry journals, the European Journal of Inorganic Sweden Belgium Chemistry and the European Journal of Organic Chemistry. Austria Portugal Poland Spain Netherlands Other ChemPubSoc Europe journals are Chemistry – A European Journal, ChemBioChem, ChemPhysChem, ChemMedChem, ChemSusChem, ChemCatChem, ChemPlusChem and ChemistryOpen. COVER PICTURE The cover picture shows how single-stranded di- nuclear lanthanide helicates (green) survive immer- sion into a drop of less polar solvent (e.g. CH2Cl2) and their eventual self-organization into a liquid- crystalline material. For alternative triple- stranded lanthanide helicates (red), drastic solvation effects lead to complete dissociation. Details are discussed in the article by E. Terazzi, C. Piguet et al. on p. 3323ff. For more on the story behind the cover research, see the Cover Profile. Eur. J. Inorg. Chem. 2013, 3273 3273 © 2013 Wiley-VCH Verlag GmbH & Co.

  • Annual Report: CY2018 Chempubsoc Europe
    1 Annual Report: CY2018 ChemPubSoc Europe Growth, change, awards, and sponsorship More scientists, more publications, more competition. As in the past, growth continued unabated worldwide in 2018 and is also reflected in the performance metrics of the ChemPubSoc Europe / Wiley-VCH publishing program, which now consists of 16 titles. The most recent product, ChemSystemsChem, was announced in Fall 2018. In 2018, the journals that are co-owned by ChemPubSoc Europe societies published nearly 9,000 articles (excluding contributions to the online publication ChemViews Magazine). Compared to the previous year, manuscript submissions grew by 12%, and the number of published articles rose by approximately 5%. A record number of full-text downloads, >8.9 million, was witnessed for the ChemPubSoc Europe journals, with increases in usage compared to the same time last year; notable among them ca. +20–30% for ChemCatChem, ChemElectroChem, ChemMedChem, and ChemPlusChem; and ca. +70% for ChemistrySelect and ChemPhotoChem. Approximately 3% of articles published in ChemPubSoc Europe's hybrid journals in 2018 were open access: ca. 10% at ChemBioChem and ca. 5% at ChemCatChem, Chemistry—A European Journal, ChemMedChem, and ChemPhysChem, respectively. ChemPubSoc Europe's gold open access journal, ChemistryOpen, experienced a ca. 47% growth in submissions compared to 2017. Generational change After the retirement of Peter Gölitz in November 2017, additional responsibility was taken on by Guido Herrmann (VP, Co-Managing Director Wiley-VCH, since April 1, 2017), Eva Wille (VP, Executive Director Wiley-VCH), Neville Compton (Editor-in-Chief of Angewandte Chemie and publisher for the GDCh journals), Haymo Ross (Editor-in-Chief of Chemistry—A European Journal and publisher of the ChemPubSoc Europe journals), Theresa Kueckmann (Editor-in-Chief of Chemistry—An Asian Journal and publisher for the Asian Chemical Editorial Society (ACES) journals), and Greta Heydenrych (development of new journals).

Desalinating saline water offers a rational choice to produce fresh water thus resolving the crisis. Among various kinds of desalination technologies, capacitive deionization (CDI) is of significant potential owing to the facile process, low energy consumption, mild working conditions, easy regeneration, low cost and the absence of secondary pollution. The electrode material is an essential component for desalination performance. The most used electrode material is carbon-based material, which suffers from low desalination capacity (under 15 mg g 1). However, · − the desalination of saline water with the CDI method is usually the charging process of a battery or supercapacitor. The electrochemical capacity of battery electrode material is relatively high because of the larger scale of charge transfer due to the redox reaction, thus leading to a larger desalination capacity in the CDI system.

Despite advances in the knowledge of parameters that drive the efficiency of enzymatic electrocatalysis, the weak stability of bioelectrodes prevents large scale development of bioelectrocatalysis. In this review, starting from the understanding of the parameters that drive protein instability, we will discuss the main strategies available to improve all enzyme stability, including use of chemicals, protein engineering and immobilization. Considering in a second step the additional requirements for use of redox enzymes, we will evaluate how far these general strategies can be applied to bioelectrocatalysis.

  • Energy Storage and Conversion Applications of Transition Metal Oxide Nanoflakes
    Energy Storage and Conversion Applications of Transition Metal Oxide Nanoflakes. A thesis submitted to the University of Dublin, Trinity College Dublin for the degree of Doctor of Philosophy in Chemistry by Aurélie A.S. Rovetta Under the supervision of Prof. Michael E.G. Lyons. School of Chemistry & CRANN Trinity College Dublin 2017 Energy Storage and Conversion Applications of Transition Metal Oxide Nanoflakes. Aurélie A.S. Rovetta Abstract In this work, MoO3 and Co(OH)2 were prepared via liquid phase exfoliation (LPE) and tested for application as supercapacitor materials and for a catalyst material for the oxygen evolution reaction (Co(OH)2 only). LPE was shown to be an effective synthetic route to prepare large quantities of high quality few layer 2-D nanosheets. When combined with liquid cascade centrifugation it allowed the size selection of the flakes within a narrow range. In chapter 4, the intercalation of lithium and potassium into MoO3 film was studied. For potassium intercalation, the influence of the support was the first parameter examined. Three carbon based support, glassy carbon, edge and basal plane pyrolytic graphite, were drop coated with the MoO3 flake suspension and double layer capacitance values of 11 mF g-1 for glassy carbon, 20 mF g-1 for pyrolytic graphite edge plane and 43 mF g-1 for basal plane were observed. The influence of the coating technique was assessed. The suspension was sprayed and phase transferred onto an ITO support electrodes and were found to have double layer capacitance values of 68 and 26 mF g-1 respectively. Lithium intercalation, for sprayed and phase transferred films displayed double layer values of 25 and 139 mF g-1 respectively.
