2014 Herbert C. Brown Award for Creative Research in Synthetic Methods

2014 Herbert C. Brown Award for Creative Research in Synthetic Methods

Paul Knochel (Ludwig-Maximilians-Universität in München, Germany) has been honored as recipient of the Herbert C. Brown Award for Creative Research in Synthetic Methods. This prestigious award is given "to recognize and encourage outstanding and creative contributions to research in synthetic methods". A special symposium to honor Knochel will take place at the upcoming 247th ACS National Meeting in Dallas. He is best known for development of novel organometallic reagents and methods for use in organic synthesis, asymmetric catalysis, and natural product synthesis and he is on the Editorial Board of ChemPlusChem.

  1. Tuning the Mechanical and Adsorption Properties of Silica with Graphene Oxide

    Dr. Vivek K. Singh, M. Erkin Cura, Dr. Xuwen Liu, Dr. Leena-Sisko Johansson, Dr. Yanling Ge and Prof. Dr. Simo-Pekka Hannula

    Get set, GO! Silica/graphene oxide (GO) composite powders of various compositions have been synthesized and compacted by spark plasma sintering. The optical and mechanical properties of silica were tuned by varying the GO content (see figure). Improved fracture toughness occurred with increasing amount of GO. Powders were also applied to Cu removal from water; the adsorption properties of silica were improved with a high concentration of GO.

  2. The Oxygen Reduction Reaction in Ferrofluids: Towards Membrane-less and Spill-less Gas Sensors

    Dr. Janjira Panchompoo, Mengchen Ge, Dr. Chuan Zhao, Dr. May Lim and Dr. Leigh Aldous

    Article first published online: 30 JUL 2014 | DOI: 10.1002/cplu.201402105

    Spill-less droplets: An aqueous ferrofluid based upon poly(diallyldimethyl ammonium chloride)-coated maghemite (γ-Fe2O3) iron oxide nanoparticles can be used on disposable screen-printed electrodes to create simple membrane-less and spill-less gas sensors (see figure). Apparent electrocatalysis towards the oxygen reduction reaction is observed owing to the polymer; an applied magnetic field strength both immobilises the electrolyte and enhances the oxygen reduction current.

  3. Mechanical Model of Globular Transition in Polymers

    Dr. Simon Tricard, Dr. Robert F. Shepherd, Dr. Claudiu A. Stan, Dr. Phillip W. Snyder, Dr. Rebecca Cademartiri, Danny Zhu, Dr. Igor S. Aranson, Prof. Eugene I. Shakhnovich and Prof. George M. Whitesides

    Different phases: A millimeter-scale granular model of coil-to-globule transitions: one “polymer” chain—a cylinders-on-a-string “pearl necklace”—and many spheres, all shaken on a horizontal surface, is described by using formalisms generally applied in statistical physics of polymers, namely, first- and second-order coil-to-globule transitions, to give insight into molecular behavior through granular experiments (see picture).

    Stratified Dipole-Arrays Model Accounting for Bulk Properties Specific to Perfluoroalkyl Compounds

    Chain effects: A perfluoroalkyl (Rf) group with (CF2)9 or longer spontaneously aggregates in a hexagonal manner through the stratified dipole-arrays aggregation mechanism, which explains Rf-specific bulk properties (see picture).

    Opening the window: Gelation of 2 M Li2SO4 with carboxymethyl cellulose (CMC) and agar results in the augmentation of the electrochemical stability window ΔE (see figure) relative to that of the liquid electrolyte, and in the reduction of the electrolyte ionic conductivity.
