Dual-Facet Mechanism in Copper Nanocubes for Electrochemical CO2 Reduction into Ethylene

Raffaella Buonsanti, Jianfeng Huang, Giulia Mangione

The product selectivity in the electrochemical reduction of carbon dioxide depends on the structure of the copper electrode. Cube-shaped copper catalysts, enclosed by {100} terraces, {110} edges, and {111} corners, exhibit a size-dependent enhanced only se ...

Catalyst Proximity-Induced Functionalization of h-BN with Quat Derivatives

Magalí Alejandra Lingenfelder, Gabriele Tocci, Bart Willem Stel, Huanyao Cun

Inert single-layer boron nitride (h-BN) grown on a catalytic metal may be functionalized with quaternary ammonium compounds (quats) that are widely used as nonreactive electrolytes. We observe that the quat treatment, which facilitates the electrochemical ...

Runaway electron modelling in the self-consistent core European Transport Simulator

Joan Decker, Gergely Papp

Relativistic runaway electrons are a major concern in tokamaks. Although significant theoretical development had been undertaken in recent decades, we still lack a self-consistent simulator that could simultaneously capture all aspects of this phenomenon. ...
