Rate-Determining Step for Electrochemical Reduction of Carbon Dioxide into Carbon Monoxide at Silver Electrodes
Sophia Haussener, Etienne Boutin
Silver is one of the most studied electrode materials for the electrochemical reduction of carbon dioxide into carbon monoxide, a product with many industrial applications. There is a growing number of reports in which silver is implemented in gas diffusio ...
2024Multiphysics model for assessing photoelectrochemical phenomena under concentrated irradiation
Sophia Haussener, Isaac Thomas Holmes-Gentle, Franky Esteban Bedoya Lora
A multiphysics model was developed for a photoelectrochemical (PEC) cell at the device level to simulate water splitting operating under concentrated irradiation (between 50 to 600 kW m−2). The 2D model couples charge, heat, mass, photon, and momentum tran ...
2023Development of new volcano-shaped microelectrodes for single cell electrochemistry, electrophysiology and impedance studies.
Micro- nano-electrodes have demonstrated superior performances in measuring attenuated intracellular action potentials from electrogenic cell cultures compared to traditional multi-electrode arrays. Yet, the understanding of the critical electrode features ...
EPFL2023Anisotropic In-Plane strain engineering Ni(OH)2 to activate alkaline hydrogen evolution reaction
Realizing a hydrogen economy strongly requires alkaline water electrolysis to achieve large-scale generation of H2, but lacks stable and efficient catalysts. The insufficient active sites in Ni(OH)2 impair the catalytic performance of alkaline HER. Herein, ...
ELSEVIER SCIENCE SA2023Fast in vivo assay of creatine kinase activity in the human brain by P-31 magnetic resonance fingerprinting
Lijing Xin, Daniel Wenz, Mark Stephan Widmaier, Songi Lim
A new and efficient magnetisation transfer P-31 magnetic resonance fingerprinting (MT-P-31-MRF) approach is introduced to measure the creatine kinase metabolic rate kCK between phosphocreatine (PCr) and adenosine triphosphate (ATP) i ...
WILEY2023Electrochemically CO2 conversion using homogeneous and nanostructured heterogeneous Ru (II) electrocatalysts
The reduction of carbon dioxide to desirable products is an urgent goal in favour of the environment, the energy-cycle and mankind. We report the electrochemical reduction of CO2 to carbon monoxide by means of the ho-mogeneous electrocatalyst (1), [Ru(bpy) ...
ELSEVIER SCI LTD2022In situ spectroelectrochemical probing of CO redox landscape on copper single-crystal surfaces
Electrochemical reduction of CO(2) to value-added chemicals and fuels is a promising strategy to sustain pressing renewable energy demands and to address climate change issues. Direct observation of reaction intermediates during the CO(2) reduction reactio ...
NATL ACAD SCIENCES2022Monitoring and understanding Cu catalyst dissolution during CO2 electroreduction
Electrochemical reduction of carbon dioxide is a promising approach to decrease the amount of anthropogenic CO2 being released into the atmosphere, provided that a surplus of renewable electrical energy is available. Copper based materials are at the cente ...
EPFL2022Electrochemical imaging of metabolic activity in tissue and biofilms
Non-invasive and semi-invasive bioimaging is of great interest for the rapid diagnosis and efficient as well as specific treatments of biological systems affecting human health, such as cancer tissue and biofilms. Electrochemical bioimaging is one of the d ...
EPFL2022Electrokinetic, electrochemical, and electrostatic surface potentials of the pristine water liquid-vapor interface
Although conceptually simple, the air-water interface displays rich behavior and is subject to intense experimental and theoretical investigations. Different definitions of the electrostatic surface potential as well as different calculation methods, each ...
