Electrochemical comparison between IrO2 prepared by anodic oxidation of pure iridium and IrO2 prepared by thermal decomposition of H2IrC16 precursor solution

Christos Comninellis, Olivier Frey, Stéphane Fierro, Lassine Ouattara

Surface redox activities, oxygen evolution reaction (OER), oxidation of formic acid (FA), and anodic stability were investigated and compared for IrO2 electrodes prepared by two techniques: the thermal decomposition of H2IrCl6 precursor (TDIROF) and the an ...

Stability of enhanced yield and metal uptake by sunflower mutants for improved phytoremediation

Jean-Paul Schwitzguebel, Erika Nehnevajova, Cécile Bourigault

Plant biomass and metal shoot accumulation are key factors for efficient phytoextraction. In a previous study, chemical mutagenesis has been used to improve the phytoextraction potential of sunflowers. The main goal of the present study was to assess the s ...

Increased tolerance of sunflower mutant seedlings to Cd and Zn in hydroponic culture

Jean-Paul Schwitzguebel, Erika Nehnevajova

Cadmium and zinc show similarities in their chemistry, geochemistry and environmental properties. Whereas Cd is a phytotoxic non-essential element, Zn is an essential trace element for plant growth and development. Zinc plays a fundamental role in several ...

Charge storage at the Pt/YSZ interface

Christos Comninellis, György Foti, Cyril Falgairette, Arnaud Jaccoud

The electrochemical behavior of Pt/YSZ electrodes in oxygen containing atmosphere at 450 A degrees C has been investigated by double-step chronoamperometry and programmed linear sweep cyclic voltammetry. The response of the O-2(g),Pt/YSZ system in these ex ...

(Pentamethylcyclopentadienyl)iridium-PTA (PTA = 1,3,5-Triaza-7-phosphaadamantane) Complexes and Their Application in Catalytic Water Phase Carbon Dioxide Hydrogenation

Paul Joseph Dyson, Gabor Laurenczy, Andrew Douglas Phillips

The water-soluble iridium(III) complexes [CpIr(PTA)Cl2] (1) and [CpIr(PTA)2Cl]Cl (2) (PTA = 1,3,5-triaza-7-phosphaadamantane) have been synthesised and characterised by spectroscopy and X-ray crystallography. The complexes were evaluated as catalyst prec ...

Synthesis of new aminophosphine complexes and their catalytic activities in C-C coupling reactions

Rosario Scopelliti, Zhaofu Fei, Wee Han Ang

Two new aminophosphines, benzyl-N(Ph2P)(2) and 2-picolyl-N(Ph2P)(2), have been synthesized. Oxidation of the aminophosphines with either hydrogen peroxide, elemental sulfur and selenium gave the corresponding oxides, sulfides and selenides benzyl-N(Ph2P=E) ...

CZE-ICP-MS as a tool for studying the hydrolysis of ruthenium anticancer drug candidates and their reactivity towards the DNA model compound dGMP

Paul Joseph Dyson, Christian Hartinger, Michael Groessl

Elucidating the mode of action and thereby opening the way to the design of chemotherapeutic agents is one of the major goals of metal-based anticancer research. Hydrolysis and DNA binding play an important role for pharmaceutical formulation and for exert ...

Selective degradation of wood lignin over noble-metal catalysts in a two-step process

Paul Joseph Dyson, Chenxu Zhao, Ning Yan, Cheng Wang

Direct conversion of lignin into alkanes and methanol was carried out in a two-step process (hydrogenolysis and hydrogenation) involving initial treatment of white birch wood sawdust with H2 in dioxane/water/phosphoric acid using carbon supported Ru, Pd, R ...
