[Article] - Nanoscale Characterization of Atomic Positions in Orthorhombic Perovskite Thin Films

Sous titre
The original multidisciplinary approach described in this article, combining X-ray and electron diffraction, electron microscopy, and ab initio calculations, has successfully resolved the crystal structure of thin films of perovskite oxides. This work provides new insights for the vanadates and a methodology for determining precisely structural distortions for other heterostructures in general.

[Workshop] - Workshop on High Entropy Alloys

Sous titre
The Institut Jean Lamour is organizing a workshop on high-entropy alloys aimed at showcasing the breadth of research conducted at the institute on this new class of materials. In addition to presentations by IJL members, we will have the honor of welcoming Prof. Brian Cantor (University of Oxford and Brunel University) as well as Prof. Erik Lewin (Uppsala University).
The workshop will be held on February 25th at Amphitheater 200 (Campus Artem)

[Article] - Influence of using individualised ergonomic handles on upper limb kinematics and neuromuscular activity, perceived comfort and performance during scull rowing

Sous titre
In 2019, the Nano-Bio-Materials for Life team was approached by the French Rowing Federation in Nancy to assist a world champion athlete suffering from motor disorders related to carpal tunnel syndrome. The team developed two grip solutions: one eliminating constraints on the affected part of the musculoskeletal chain, and the other alleviating them. Both solutions were patented in 2022 and 2025. This work subsequently led to the writing of this article.
This article explores the biomechanical consequences of using customized ergonomic equipment for each high-level single sculler on the water. It validates an ergonomic handle designed and manufactured in Nancy in the context of high-performance sports.

[Article] - Microstructure optimization by combinatorial approach applied to Duplex Medium Manganese steels

Sous titre
This publication marks the first contribution from the "Microstructures and Stresses" group within the framework of the DIAMS project (PEPR DIADEM). It demonstrates the feasibility of studying phase transformations in combinatorial metallurgy by leveraging the "process" parameters of the design space.
This result stems from a significant collaboration between IJL, SIMAP, LEM3, and ESRF, with whom the team is developing the Long Term Partnership "CombiMet."

[Article] - TEM in situ crystallization of SmNiO3 nanoparticles

Sous titre
Amorphous Sm–Ni–O nanoparticles produced by laser ablation were crystallized into the perovskite phase (SmNiO3) via in situ thermal treatments in the TEM. This study demonstrated that the initial Sm/Ni stoichiometry of the nanoparticles plays an important role during crystallization, as confirmed by analysis of high-resolution TEM images and by the increase in the Ni3+/Ni2+ ratio, a clear indicator of perovskite formation-measured by EELS.

[Article] - Health monitoring of NiTi endodontic instruments using acoustic Emission: Spectral indicators for predictive damage detection

Sous titre
Ce travail a pour objectif ultime de concevoir un dispositif capable de surveiller en temps réel l’endommagement d’une lime endodontique par analyse acoustique, afin d’alerter le chirurgien-dentiste en cas de risque imminent de rupture et de lui signaler la nécessité d’interrompre immédiatement son utilisation. Cette approche fondée sur l’émission acoustique est appliquée pour la première fois en endodontie. Cet article présente une première proposition de critère d’alarme acoustique.

[Article] - When temperature and flow intertwine to stir up fusion plasmas

Sous titre
Selected as an Editor’s Pick, this article uncovers unexpected interactions between two types of instabilities in hot plasmas and demonstrates, for the first time, the capability of an advanced simulation code to accurately model these phenomena in the cylindrical SPEKTRE experiment at IJL.

[Article] - Watching Steel Transform in Real Time at High Temperatures

Sous titre
This work clarifies the actual conditions under which dynamic transformation occurs in steel during hot deformation. Using synchrotron X-ray diffraction, it demonstrates that conventional methods often overestimate both the extent and the temperature range of such transformations.
