Simulation of turbulent lithium transport in fusion reactors

Sous titre
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.

AI That Enables Real-Time Analysis of Steel Microstructure Using X-Ray Diffraction

Sous titre
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.

Study of electric arc dynamics using three-dimensional reconstruction: application to the detection of electrical faults in the aerospace industry

Sous titre
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.

Overlay of two plasma reconstructions with reversed electrode polarities. The dotted line indicates the boundary between the two distinct experiments with reversed polarities. In both cases, the plasma corresponds to a 4 A arc at atmospheric pressure with a gap of 10 mm, observed 4 seconds after ignition.

Humidity and CO₂: understanding to capture better

Sous titre
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.

[Article] - Spin texture of α-GeTe in the ultrathin regime

Sous titre
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.

[Article] - Study of the viability of calcifying bacteria of the genus Bacillus pseudofirmus in the ultra-alkaline environment of various Portland cement pastes in order to fill autonomously micro-cracks.

Sous titre
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
