      Cover Picture: Kinetic Passivation Effect of Localized Differential Aeration on Brass (ChemPlusChem 1/2016) (page 1)

      Dr. Volodymyr Kuznetsov, Dr. Arturo Estrada-Vargas, Dr. Artjom Maljusch, Dr. Balázs B. Berkes, Prof. Dr. Aliaksandr S. Bandarenka, Prof. Dr. Ricardo M. Souto and Prof. Dr. Wolfgang Schuhmann

      Article first published online: 2 DEC 2015 | DOI: 10.1002/cplu.201500521

      Thumbnail image of graphical abstract

      The cover picture shows the passivation effect of a liquid in a brass tube in the presence of oxygen in the gas phase. The resulting differential aeration conditions promote the passivation of brass at short exposure times as revealed in images recorded by alternating current scanning electrochemical microscopy (AC-SECM) which were generated by holding the SECM tip over the temporarily passivated area. Details are given in the Full Paper by Wolfgang Schuhmann et al. on page 49 in Issue 1, 2016 (DOI: 10.1002/cplu.201500398).

      Back Cover: Radicals and Dormant Species in Biology and Polymer Chemistry (ChemPlusChem 1/2016) (page 154)

      Prof. Chryssostomos Chatgilialoglu, Dr. Carla Ferreri and Prof. Krzysztof Matyjaszewski

      Article first published online: 13 NOV 2015 | DOI: 10.1002/cplu.201500504

      Thumbnail image of graphical abstract

      The cover picture shows the encounter of free radicals and dormant species in biological systems and in synthetic polymer chemistry. The radical-based processes link chemistry with biology and medicine, creating a truly multidisciplinary field. A challenging control of very reactive radical intermediates has been accomplished in polymer chemistry through dynamic exchange between radicals and dormant species (ATRP, OMRP/NMP, RAFT), paralleling the control in biological processes (RNR, SAM, cobalamine). Details are given in the Review by C. Chatgilialoglu, C. Ferreri, and K. Matyjaszewski on page 11 in Issue 1, 2016 (DOI: 10.1002/cplu.201500271). The background shows “the near-touching hands”, a detail of the Creation of Adam by Michelangelo“.

      Radicals and Dormant Species in Biology and Polymer Chemistry (pages 11–29)

      Prof. Chryssostomos Chatgilialoglu, Dr. Carla Ferreri and Prof. Krzysztof Matyjaszewski

      Article first published online: 4 AUG 2015 | DOI: 10.1002/cplu.201500271

      Thumbnail image of graphical abstract

      Radical innovation: The past two decades have witnessed significant advances in the understanding of the role and methods of creation and control of free radicals in biological and polymerization processes. A commonality between polymers and life sciences, distant fields at first glance, can be found in their controlled radical reactivity, that is, the persistency of radical species. They resemble “Sleeping Beauty” to give marvelous results upon their awakening. The relevant convergences have been highlighted in this Review with seminal examples and parallelisms, thereby providing multidisciplinarity as a necessary driver of radical innovation in basic and applied science.

      Thumbnail image of graphical abstract

      Waterline passivation: A differential aeration cell formed at the meniscus between air and electrolyte invokes local corrosion of brass. In the presence of inhibitors, a short-term passivation effect takes place that can be analyzed by spectroscopic and local electrochemical techniques (see figure). Simultaneous rapid cathodic alkalinization and dezincification lead to the rapid formation of a barrier layer that is temporarily superior to the bulk layer.
