Accelerated Workflow for Antiperovskite-based Solid State Electrolytes

Andrea Fedrigucci, Ivano Eligio Castelli

We developed and implemented a multi-target multi-fidelity workflow to explore the chemical space of antiperovskite materials with general formula X(3)BA (X=Li, Na, Mg) and Pm-3m space group, searching for stable high-performance solid state electrolytes f ...

Data Management Plans: the Importance of Data Management in the BIG-MAP Project[**]

Nicola Marzari, Giovanni Pizzi, Martin Uhrin, Ivano Eligio Castelli

Open access to research data is increasingly important for accelerating research. Grant authorities therefore request detailed plans for how data is managed in the projects they finance. We have recently developed such a plan for the EU H2020 BIG-MAP proje ...

Yttrium Tantalum Oxynitride Multiphases as Photoanodes for Water Oxidation

Nicola Marzari, Ivano Eligio Castelli

The perovskite yttrium tantalum oxynitride is theoretically proposed as a promising semiconductor for solar water splitting because of the predicted band gap and energy positions of band edges. In experiments, however, we show here that depending on the pr ...

Highly Active Nanoperovskite Catalysts for Oxygen Evolution Reaction: Insights into Activity and Stability of Ba0.5Sr0.5Co0.8Fe0.2O2+delta and PrBaCo2O5+delta

Nicola Marzari, Ivano Eligio Castelli, Xi Cheng

It is shown that producing PrBaCo2O5+delta and Ba0.5Sr0.5Co0.8Fe0.2O2+delta nanoparticle by a scalable synthesis method leads to high mass activities for the oxygen evolution reaction (OER) with outstanding improvements by 10x and 50x, respectively, compar ...

Precision and efficiency in solid-state pseudopotential calculations

Nicola Marzari, Nicolas Frank Mounet, Antimo Marrazzo, Ivano Eligio Castelli, Gianluca Prandini

Despite the enormous success and popularity of density-functional theory, systematic verification and validation studies are still limited in number and scope. Here, we propose a protocol to test publicly available pseudopotential libraries, based on sever ...

Determination of Conduction and Valence Band Electronic Structure of LaTiOxNy Thin Film

Nicola Marzari, Ivano Eligio Castelli, Alexander Wokaun

The nitrogen substitution into the oxygen sites of several oxide materials leads to a reduction of the band gap to the visible-light energy range, which makes these oxynitride semiconductors potential photocatalysts for efficient solar water splitting. Oxy ...
