Sodium chromium hexacyanoferrate as a potential cathode material for aqueous sodium-ion batteries

Hubert Girault, Emad Oveisi, Pierre Mettraux, Dominika Baster, Surbhi Agrawal

Sodium chromium hexacyanoferrate (NaCrHCF) is obtained here using a facile co-precipitation method at room temperature. The powder was investigated in terms of potential use as a cathode material for aqueous sodium-ion batteries under neutral conditions. T ...

Overview on recent progress in magnetron injection gun theory and design for high power gyrotrons

Stefano Alberti, Jean-Philippe Hogge, Jérémy Genoud, Ioannis Pagonakis, Konstantinos Avramidis

The magnetron injection gun (MIG) is one of the most critical subcomponents in gyrotrons. The electron beam, which has the primary role on the gyrotron operation, is generated and configured at this part of the tube. The electron beam properties determine ...

Energetics and cathode voltages of LiMPO4 olivines (M = Fe, Mn) from extended Hubbard functionals

Nicola Marzari, Matteo Cococcioni

Transition-metal compounds pose serious challenges to first-principles calculations based on density functional theory (DFT), due to the inability of most approximate exchange-correlation functionals to capture the localization of valence electrons on thei ...

The role of malachite nanorods for the electrochemical reduction of CO2 to C-2 hydrocarbons

Emad Oveisi, Jie Zhang, Kun Zhao, Mariana Spodaryk

The electrochemical reduction of CO2 to higher hydrocarbons is a very challenging process that has high potential for the storage of large amounts of renewable energy with a high gravimetric and volumetric energy density. The distribution of hydrocarbons f ...

Effect of the electrochemical characteristics of titanium on the adsorption kinetics of albumin

An electrochemical quartz crystal microbalance (EQCM) was used to examine the electrochemical behaviour of pure titanium in phosphate buffered saline (PBS) and PBS-containing bovine serum albumin (BSA) solutions, and the associated adsorption characteristi ...

Linear collisionless dynamics of the GAM with kinetic electrons: Comparison simulations/theory

Alberto Bottino

Barely trapped and passing electrons have been recently predicted to strongly enhance the damping rate of Geodesic Acoustic Modes (GAMs) in tokamak plasmas, while keeping their real frequency almost unchanged as compared to the case with adiabatic electron ...

Modeling of parasitic oscillations in smooth-wall circular symmetric dielectric-loaded gyrotron beam ducts

Stefano Alberti, Jean-Philippe Hogge, Jérémy Genoud

The self-consistent simulation of the electron beam interaction was performed in the presence of a lossy dielectric layer in the smooth-wall beam duct of a gyrotron oscillator. For this purpose, the linear and spectral code TWANGlinspec was extended. In th ...

Degradation analysis of commercial interconnect materials for solid oxide fuel cells in stacks operated up to 18000 hours

Jan Van Herle, Manuel Bianco

Despite being a mature technology, solid oxide fuel cell (SOFC) devices are still limited by lifetime issues. In SOFC stacks, cell/interconnect interaction is the main responsible for voltage degradation at the oxygen electrode side. Corrosion and chromium ...

Ultrafast Studies of Hot-Hole Dynamics in Au/p-GaN Heterostructures

Giulia Tagliabue

Harvesting non-equilibrium hot carriers from photo-excited metal nanoparticles has enabled plasmon-driven photochemical transformations and tunable photodetection with resonant nanoantennas. Despite numerous studies on the ultrafast dynamics of hot electro ...
