A bimetallic nanocoral Au decorated with Pt nanoflowers (bio)sensor for H2O2 detection at low potential

Giovanni De Micheli, Sandro Carrara, Irene Taurino, Francesca Puppo

In this work, we have developed for the first time a method to make novel gold and platinum hybrid bimetallic nanostructures differing in shape and size. Au-Pt nanostructures were prepared by electrodeposition in two simple steps. The first step consists o ...

Chemical Distribution of Multiple Cation (Rb+, Cs+, MA(+), and FA(+)) Perovskite Materials by Photoelectron Spectroscopy

Michael Graetzel, Ulf Anders Hagfeldt, Michael Saliba, Juan-Pablo Correa-Baena

Lead-based mixed perovskite materials have emerged in the last couple of years as promising photovoltaic materials. Recently, it was shown that improved material stability can be achieved by incorporating small amounts of inorganic cations (Cs+ and Rb+), p ...

Nitrification increases nitrogen export from a tropical river network

Janine Rüegg

Scaling aquatic ecosystem processes like nutrient removal is critical for assessing the importance of streams and rivers to watershed nutrient export. We used pulse NH4+ enrichment experiments and measured net NH4+ uptake in 7 streams throughout a mountain ...

Carbon Dioxide Based N-Formylation of Amines Catalyzed by Fluoride and Hydroxide Anions

Paul Joseph Dyson, Felix Daniel Bobbink, Shoubhik Das, Martin Hulla

We described herein a simple approach for N-formylation with CO2 and hydrosilane reducing agents. Fluoride and hydroxide salts efficiently catalyzed the reaction, principally through activation of the hydrosilanes, which led to hydrosilane reactivities com ...

Electrochemical oxygen reduction at soft interfaces catalyzed by the transfer of hydrated lithium cations

Hubert Girault, Pekka Eero Peljo, Haiqiang Deng, Thomas James Stockmann

The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...

An Imine-Based Molecular Cage with Distinct Binding Sites for Small and Large Alkali Metal Cations

Rosario Scopelliti, Kay Severin, Clément Schouwey

The synthesis of a cylindrical, imine-based cage composed of two trimeric metallamacrocycles is described. The cage acts as a heterotopic receptor for alkali metal cations. The small cations Li+, Na+, and K+ bind to the outside of the cage with good select ...
