Potential-sensing electrochemical atomic force microscopy for in operando analysis of water-splitting catalysts and interfaces

Kevin Sivula

Heterogeneous electrochemical phenomena, such as (photo)electrochemical water splitting to generate hydrogen using semiconductors and/or electrocatalysts, are driven by the accumulated charge carriers and thus the interfacial electrochemical potential grad ...

Majority Logic Synthesis

Giovanni De Micheli, Mathias Soeken, Luca Gaetano Amarù, Eleonora Testa, Odysseas Zografos

The majority function (xyz) evaluates to true, if at least two of its Boolean inputs evaluate to true. The majority function has frequently been studied as a central primitive in logic synthesis applications for many decades. Knuth refers to the majority f ...

SECM study of hydrogen photogeneration in a 1,2-dichloroethane | water biphasic system with decamethylruthenocene electron donor regeneration

Hubert Girault

This paper reports light driven hydrogen evolution reaction (HER) at 1,2-dichloroethane | water (DCE | W) interface using photoexcited decamethylruthenocene (DMRc) as electron donor. DMRc is in situ regenerated by electroreduction of its oxidized form (DMR ...

Pyrazolium Ionic Liquid Co-catalysts for the Electroreduction of CO2

Paul Joseph Dyson, Dmitry Vasilyev, Erfan Shirzadi

Pyrazolium ionic liquids (Pz ILs) were employed as co-catalysts for electrochemical conversion of CO2 to CO on a silver disk electrode, leading to a significant decrease in the onset potential for the reduction (ca. 500 mV). The electrochemical conversion ...

Electrochemical Reduction of Protic Supercritical CO2 on Copper Electrodes

Victor Costa Bassetto, Alberto Battistel, Patrick Voyame, Olga Melchaeva

The electrochemical reduction of carbon dioxide is usually studied in aqueous solutions under ambient conditions. However, the main disadvantages of this method are high hydrogen evolution and low faradaic efficiencies of carbon-based products. Supercritic ...
