Reactions of alpha,beta-Unsaturated Carbonyls with Free Chlorine, Free Bromine, and Combined Chlorine

Chemical disinfectants employed in water and wastewater treatment can produce a variety of transformation products, including carbonyl compounds (e.g., saturated and unsaturated aldehydes and ketones). Experiments conducted under conditions relevant to chl ...

Mechanistic Studies of Two Ni-Catalyzed Reactions: Reductive Amidation of Esters with Nitroarenes and Hydrosilylation of Alkenes

Marten Leendert Ploeger

Mechanistic investigations into homogeneously catalyzed reactions are essential for the fur-ther development of synthetic methodologies. Insights in the overall reaction pathway and vital steps such as the rate-determining and selectivity-determining steps ...

High-Valent Nickel Promoted by Atomically Embedded Copper for Efficient Water Oxidation

Jun Li, Ning Wang, Yun Liu, Bo Zhang

Efficient and low-cost electrocatalysts for oxygen evolution reaction (OER), particularly in neutral conditions, are of significant importance for renewable energy technologies such as CO2 reduction and seawater splitting electrolysis. High-valent transiti ...

Impact of cation redox chemistry on continuous hydrothermal synthesis of 2D-Ni(Co/Fe) hydroxides

Andreas Stephan Lesch, Massimo Rosa

Continuous hydrothermal flow synthesis (CHFS) is a facile, upscalable and cost-efficient synthetic method enabling the nanostructuring of advanced functional materials in steady conditions, i.e. not in batch synthesis. In this paper, we use CHFS to crystal ...

Fe-Ni ideality during core formation on Earth

James Badro

Earth's core is essentially composed of a light-element bearing iron-nickel alloy (Birch 1964). The nickel content in the core has negligible effects on physical properties such as density and compressibility (e.g., Lin et al. 2003; Kantor et al. 2007; Mar ...

Formation of brominated trihalomethanes during chlorination or ozonation of natural organic matter extracts and model compounds in saline water

Urs von Gunten

Oxidation experiments (chlorine, ozone and bromine) were carried out with synthetic saline waters containing natural organic matter (NOM) extracts and model compounds to evaluate the potential of these surrogates to mimic the formation of brominated trihal ...

Solid oxide fuel cell anode degradation by the effect of hydrogen chloride in stack and single cell environments

Jan Van Herle, Christian Ludwig, Stefan Diethelm, Hossein Madi, Davide Papurello

The poisoning effect by hydrogen chloride (HCl) on state-of-the-art Ni anode-supported solid oxide fuel cells (SOFCs) at 750 degrees C is evaluated in either hydrogen or syngas fuel. Experiments are performed on single cells and short stacks and HCl concen ...

A Functional Model of [Fe]-Hydrogenase

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Tao Xu, Simona Mazza

[Fe]-Hydrogenase catalyzes the hydrogenation of a biological substrate via the heterolytic splitting of molecular hydrogen. While many synthetic models of [Fe]-hydrogenase have been prepared, none yet are capable of activating H-2 on their own. Here, we re ...

Regioselective Nitration and/or Halogenation of Iridabenzofurans through Electrophilic Substitution

Andrew Francis Dalebrook

Regioselective electrophilic substitution reactions of the iridabenzofurans [Ir(C7H5O{OMe-7})(CO)(PPh3)(2)]-[OTf] (1) and IrCl(C7H5O{OMe-7})(PPh3)(2) (2) provide a convenient route to mononitro-, dinitro-, and mixed nitro-/halo- substituted derivatives. Tr ...

A TEM study of Ni interfaces formed during activation of SOFC anodes in H 2 : Influence of grain boundary symmetry and segregation of impurities

Jan Van Herle, Cécile Hébert, Aïcha Hessler-Wyser, Quentin Thomas Jeangros

The electrochemical properties of a solid oxide fuel cell depend on many parameters, including – on the anode side – the connectivity of the Ni network and the segregation of impurities at active points. In this work, advanced scanning transmission electro ...
