2023 Roadmap on molecular modelling of electrochemical energy materials

Alfredo Pasquarello, Chunmin Zhang, Assil Bouzid

New materials for electrochemical energy storage and conversion are the key to the electrification and sustainable development of our modern societies. Molecular modelling based on the principles of quantum mechanics and statistical mechanics as well as em ...

Chalcogenide glasses for innovation in applied science: fundamental issues and new insights

Assil Bouzid, Carlo Massobrio

We provide an overview of what has been accomplished by our team, since 1998, in the area of first-principles molecular dynamics (FPMD) modeling of glassy chalcogenides, a prototypical family of network-forming disordered materials. After a broad introduct ...

Reaction pathway of oxygen evolution on Pt(111) revealed through constant Fermi level molecular dynamics

Alfredo Pasquarello, Assil Bouzid, Patrick Gono

The pathway of the oxygen evolution reaction at the Pt(111)/water interface is disclosed through constant Fermi level molecular dynamics. Upon the application of a positive bias potential H2Oads and OHads adsorbates are found to arrange in a hexagonal latt ...

Oxide versus Nonoxide Cathode Materials for Aqueous Zn Batteries: An Insight into the Charge Storage Mechanism and Consequences Thereof

Alfredo Pasquarello, Assil Bouzid

Aqueous Zn-ion batteries, which are being proposed as large-scale energy storage solutions because of their unparalleled safety and cost advantage, are composed of a positive host (cathode) material, a metallic zinc anode, and a mildly acidic aqueous elect ...

Defect Formation Energies of Interstitial C, Si, and Ge Impurities in beta-Ga2O3

Alfredo Pasquarello, Assil Bouzid

Formation energies of C, Si, and Ge defects in beta-Ga2O3 are studied through hybrid functional calculations. The interstitial defects of these elements generally occur at higher energies than their substitutional counterparts, but are more stable at low F ...

The role of dispersion forces on the atomic structure of glassy chalcogenides: The case of GeSe4 and GeS4

Assil Bouzid, Carlo Massobrio

Recent first-principles molecular dynamics simulations (FPMD) results on two chalcogenide glasses (glassy GeS4 and GeSe4) are revisited by accounting explicitly for van der Waals (vdW) dispersion forces. This effort is motivated by the observation that suc ...

Sensitivity to Dispersion Forces in First-Principles Modeling of Disordered Chalcogenides

Assil Bouzid, Carlo Massobrio

The inclusion of dispersion (van der Waals, vdW) forces in first-principles modeling of disordered chalcogenides is analyzed and critically discussed in view of their impact on the atomic structure. To this purpose we considered the case of glassy GeTe4. W ...

FRONTIERS MEDIA SA2018

Because of the broad range of application of iron oxide nanoparticles (NPs), the control of their size and shape on demand remains a great challenge, as these parameters are of upmost importance to provide NPs with magnetic properties tailored to the targe ...

AMER CHEMICAL SOC2018

The amorphous structure of the phase change material Ge2Sb2Te5 (GST) has been the object of controversial structural models. By employing first-principles molecular dynamics within density functional theory, we are able to obtain quantitative agreement wit ...

Amer Physical Soc2017

Aset of structural properties of liquid GeSe2 are calculated by using first-principles molecular dynamics and including, for the first time, van derWaals dispersion forces. None of the numerous atomic-scale simulations performed in the past on this prototy ...
