A Cation Concentration Gradient Approach to Tune the Selectivity and Activity of CO2 Electroreduction

The linear scaling relationship of the binding energies of different intermediates limits the catalyst performance in CO 2 electroreduction. Here we demonstrate a cation concentration gradient strategy to promote the activity and tune the selectivity of CO ...

Mechanistic implications of lanthanum-modification on gold-catalyzed formic acid decomposition under SCR-relevant conditions

Oliver Kröcher, Davide Ferri

The use of formate-based ammonia precursors as alternatives to urea in the selective catalytic reduction (SCR) process requires that formic acid released upon their thermolysis in the hot exhaust is rapidly decomposed to carbon dioxide. This work aims at t ...

Promotion Effect of Alkali Metal Hydroxides on Polymer-Stabilized Pd Nanoparticles for Selective Hydrogenation of C–C Triple Bonds in Alkynols

Paul Joseph Dyson, Lioubov Kiwi, Jeremy Luterbacher, Florent Emmanuel Héroguel

Postimpregnation of Pd nanoparticles (NPs) stabilized within hyper-cross-linked polystyrene with sodium or potassium hydroxides of optimal concentration was found to significantly increase the catalytic activity for the partial hydrogenation of the C–C tri ...

Analyzing ion distributions around DNA

John Maddocks, Marco Pasi

We present a new method for analyzing ion, or molecule, distributions around helical nucleic acids and illustrate the approach by analyzing data derived from molecular dynamics simulations. The analysis is based on the use of curvilinear helicoidal coordin ...

Resilience of acid subalpine grassland to short-term liming and fertilisation

Thomas Spiegelberger

A fertilisation experiment was started in the French Alps on an acid grassland at 2000 m in 1989 where lime as calcium carbonate ("liming") and Thomas Slag enriched by potassium chloride ("fertilisation") were added in a random block design until 1992. Sin ...

Structure of nitrile-functionalized alkyltrifluoroborate salts

Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Dongbin Zhao

Two nitrile-functionalized alkyltriflouroborate anion based complexes [(Ph3P)(2)N][CH3CH(BF3)CH2CN] and [K(18-crown-6)][CH3CH(BF3)CH2CN] were synthesized and characterized by spectroscopic methods and single X-ray diffraction analysis. In the former comple ...
