This paper presents a new method to determine the turbulent transport coefficients of an impurity using the gyrokinetic code GYSELA. Applied to lithium, with and without a transport barrier, it provides initial results on this promising species for next-generation plasma-facing components.

À l’occasion de la Semaine de la recherche, l’Institut Jean Lamour a accueilli 80 étudiants pour un après-midi consacré à la découverte de la recherche en physique et en chimie, à travers des visites d’équipements et des échanges avec des chercheurs, des doctorants et des responsables de formation.

This work introduces an AI-based method to quantify phase fractions in steels directly from X-ray diffraction data in real time. It overcomes the limitations of traditional time-consuming analysis methods and enables fast, high-throughput experiments with real-time feedback.

This article presents the first study of the correlation between plasma dynamics and the electrical signature of an arc across different frequency ranges, based on a time-resolved three-dimensional reconstruction.

The capture and storage of CO₂ using porous materials is one of the strategies being explored to combat climate change. However, humidity—present everywhere—tends to adsorb preferentially onto most solids, reducing their capacity to capture CO₂.

Ferroelectric Rashba semiconductors such as α-GeTe have recently emerged as promising candidates for all-electrically controlled spin-orbitronics. The persistence of Rashba spin-split electronic states in ultrathin α-GeTe films is of utmost importance in the context of device downscaling. Using spin- and angle-resolved photoemission spectroscopy supported by first-principle calculations, the authors here demonstrate that α-GeTe films as thin as 5 nm still exhibit an in-plane spin texture at the Fermi surface.

The highlights of this article are:
• Bacillus pseudofirmus enabled calcite mineralization on 3 pure cement pastes
• Bacillus pseudofirmus enabled the complete filling of 9 mm3 holes in cement pastes in 21 days
• The bio-induced precipitation of calcite leads to the coating of bacterial cells
